Title: So ... 3d Printers....
Post by: Howard_Casto on November 26, 2016, 12:54:56 pm
It's that time of year again and all the low to mid end 3d printers are on sale.  I'm considering it this time, but I'm a little overwhelmed from all the choices. 

Thus far these two stick out on the low end:

http://www.monoprice.com/product?c_id=107&cp_id=10724&cs_id=1072403&p_id=15365&seq=1&format=2&AID=11064683&PID=4485850&ref=cj&utm_source=cj&utm_medium=11064683&utm_term=Slickdeals+LLC-1122587 (http://www.monoprice.com/product?c_id=107&cp_id=10724&cs_id=1072403&p_id=15365&seq=1&format=2&AID=11064683&PID=4485850&ref=cj&utm_source=cj&utm_medium=11064683&utm_term=Slickdeals+LLC-1122587)

I believe this is the one a bunch of you got a while back.  It seems to be built to high quality and it isn't a kit, which is nice.  Then I found this one....

http://www.gearbest.com/3d-printers-3d-printer-kits/pp_343643.html?wid=8&siteid=136649&utm_source=webgains&utm_campaign=GearbestUSA (http://www.gearbest.com/3d-printers-3d-printer-kits/pp_343643.html?wid=8&siteid=136649&utm_source=webgains&utm_campaign=GearbestUSA)

Now obviously it's a kit, it's constructed of a cheaper lexan base, and the fit and finish isn't as nice but....  it has a build volume of 220x220x240mm!  That's nearly a 10 inch cube!

So suggestions or comments sure would be appreciated.  I really like the larger build size of the cheaper model, but if it's a piece of junk all the extra volume is pointless.

I got the monoprice mini for $170.  The learning curve for it isn't nearly what I expected.
Make crap in tinkercad>export stl file>open in the copy of Cura included with the printer>export gcode to microsd card>pop in printer and select file.
I cranked out this fairly quickly: http://forum.arcadecontrols.com/index.php/topic,152133.0.html (http://forum.arcadecontrols.com/index.php/topic,152133.0.html)
I also made a bracket to hold my cell phone right under the radio in my truck.
So far, I only have a couple ideas in my head that I'd need a larger printer for, but decided I'd just join the local maker space and use their 3D printer after I get the designs done.
For me, this purchase was all about getting my feet wet and moving along the learning curve.  It has been great for that.

As far as the other one, I'd probably still be a bit intimidated by the user interface and needing to tweak it to get better results.
The guy in the video sounds like he had some issues before printing modifications for it.

So as a total noob I'd want the monoprice one, but if I were more experienced the bigger one would be better.

After I get experienced with design software more complicated with Tinkercad, I'll probably move up to a bigger machine.

Well the tinkering I expect, but there are a few issues creeping up with the china unit.  Apparently the included software isn't supported by win 10.  I'm sure you can download something else, but that means software tinkering as well.  Also I'm unsure if it comes with sample filament, which isn't a huge deal, but then it isn't really cheaper.  I'll have to research more.  I'm waiting until Monday to see if there are any sales.

The amount of filament the monoprice comes with isn't really enough to make anything.
For me, it did the bed level test print (per the instructions) and about 1/5th of the included cat figurine.
Rough estimate: only pennies worth of filament.

Well I'm just wondering how much I'll waste before getting it calibrated properly.  Yeah it's probably not enough to matter, but when you'll throw a decent portion in the trash every little bit helps. 

They've also sold out at the LA warehouse, meaning shipping isn't free and it'll likely come over on the slow boat from China.

When I get a 3D printer, I intend to build a grinder/extruder to recycle botched prints.

Howard - No.  No new projects.

Finish up your other projects first.  My Everdrive purchase is on hiatus until you clean up that front end.

I was just reading up on that.  One guy made a pellet extruder that you just swap out instead of the normal filament extruder.  He's gotten decent results thus far but the thing about pellets is you typically have to buy them in massive quantities to get those big savings. 

I'm impressed with what you can print with now.  They have metal filament, wood-like filament and even felt filament. 

pbj:  This would probably give me more time to work on that junk.  The physical building of my racing cab has taken up the bulk of my time.  Being able to just print the fiddly bits would be a huge help.  Are you talking about the n64 one?  The third party FE isn't that bad once you get it configured.... it probably needs a bit more fit and finish though.

Been researching this tonight.  Man my head is spinning.... so many options.  I found one that is an i3 clone (apparently the Chinese model and several others are just i3 clones) and uses a rigid steel construction.... it's a slightly smaller print area, but many of the bugs have been fixed.  Unfortunately the shipping is ridiculously high... I think the cheapest option was 70 bucks.  Maybe this is why many of the diy kits are acrylic based.   

Still torn between the two.  Something that is leaning me towards the monoprice one is the fact that it hasn't been known to catch fire.  Apparently many of the i3 clones use sub-standard connectors that can heat up and melt over time.  So right out of the box it has to be modded with molex connectors.

Eh, I thought you were hacking the NES and Genesis Everdrives.  Nobody cares about N64.  Get that 3D printer.

Title: Re: So ... 3d Printers....
Post by: Howard_Casto on November 28, 2016, 04:27:49 pm
Well if somebody can find me some source code I can.  The n64 cart has an open-source alternative.  The others don't afaik.

I have the Anet A8.  It definitely needs some upgrades and several plugs and wires are undersized which are a known fire hazard.  Expect to spend an extra $100 or so on upgrades.  That said, I really like it.  It's my second 3d printer and it has worked really well for me.  The print volume really sold it for me.  If you can live with a bit smaller print volume I'd go with one of the smaller Prusia I3 based units that doesn't need quite so many upgrades.

With RepRap based printers like the A8 or other Prusia I3 based units, you really don't need to worry about included software as there are many free and often open source options that work well.  Some of the closed source hardware designs may lock you into certain software.  The Anet controller board firmware is not open source but there is a group called Skynet3D that has an alternative firmware available that's I believe open source (free anyway).

Starter filament I wouldn't worry about since you will need far more to get things dialed in and then plenty more for printing.

They are available from more places than Gearbest but pretty much all of the sources I've heard of have non-existent customer service.  I got mine from https://www.3dprintersbay.com (https://www.3dprintersbay.com) which lists a US address but ships from China. 
Ship time was a bit under 2 weeks but might be more now with the holidays.
Title: Re: So ... 3d Printers....
Post by: Howard_Casto on November 28, 2016, 11:32:11 pm
My next question was going to be where to buy.  Gearbest is out... as you said their customer service isn't great, they are out of units in the US, and shipping is no longer free. 

I've found a ton of i3 clones on ebay/amazon/ect.  Some have anet pcbs and some have melzi.  I've heard bad things about both so I'm not sure which one to get.  The melzi are slightly cheaper which makes me think they are worse.

The build size is what interests me.  It's large enough to print enclosures for projects without having to print in pieces. 

I want to try and get one that's already in the USA just so it'll get here before the holidays. 
Title: Re: So ... 3d Printers....
Post by: SammyWI on November 29, 2016, 08:39:21 am
I believe the Anet PCB is a rearranged Melzi. But I am seeing reports that people are getting newer Anet boards that have improved connectors which is good. I've seen some other variations between kits. Some have gotten acrylic sub frames on the heat bed which is not as good as the aluminum that I got.

Keep in mind that printing right up to the edge of the designed print volume can be difficult. I try to leave some margin. And large prints are both more difficult to print and can take a very long time.
Title: Re: So ... 3d Printers....
Post by: Howard_Casto on November 29, 2016, 04:08:01 pm
Well then I'm probably seeing an older model of the same printer then, and that's the reason for the discount. 

How could I tell about the printer sub-frame?  It's covered in most pics, but if I knew what to look for...

I'm aware I can't print to the bounds easily, but the monoprice ones are so much smaller I'm thinking they would struggle to print out... let's say a Gameboy shell or something similar. 
Title: Re: So ... 3d Printers....
Post by: SammyWI on November 29, 2016, 07:03:50 pm
I don't think you can really tell anything about what particular changes you might get from the resellers pages or photos.  I doubt the resellers themselves have much of a clue, they just get the boxes from China and ship them out.  These Chinese manufacturers tend to make small changes and upgrades as they go without updating descriptions, etc.  Can make assembly interesting! These printers seem to be selling like mad so I doubt you'll really find old stock anywhere.

Most all of the printer parts are available cheaply from Chinese suppliers. Sometimes quality is too cheap but for the most part I have had good luck.  I know an aluminum sub bed is available from other places or making one would not be very hard. It becomes slightly addicting to upgrade and mod your printer when you see parts on Amazon Prime for $10.

A gameboy shell should not be too difficult at all to print.  I looked up sizes and I saw less than 150mm as the biggest dimension.  I'd say you could print that on a 170mm bed or larger very easily.  Pushing things nearly to the edges should be possible but may be more challenging.

If you see versions that have an auto bed level upgrade, don't get it.  I bought that version and it did not actually do auto bed leveling, it just swapped the typical Z home limit switch (physical microswitch) for an inductive sensor that senses the aluminum build plate.  I ended up buying a new inductive sensor (better range and repeatability) and changing to the Skynet3D firmware to enable auto leveling. A very worthwhile upgrade IMO.

Materials: I would stay away from ABS.  I used it for several years and always had problems.  The main issue is that it shrinks when cooling which leads to it pealing of the bed when printing, warping and just a general pain. PLA is the easiest printing material and works for many parts, would probably be fine for gameboy shells.  For stronger and more heat resistant stuff I use PETG.  PETG is also more flexible in thin sections and comes in both opaque and translucent colors.  Both PLA and PETG (and ABS) print at temps low enough for the Anet hot end. Some materials require higher temps (nylon and polycarbonate for example) and really need the hotend changed to an all metal version.  The included hot end has a teflon liner which will melt and give off nasty gasses if heated too high.  How high is too high is debatable but I like to keep mine to 240 C and below.

I'm rambling, I know but I'm at home now with a real keyboard to type on.  And it's nice to talk about this on a real forum rather than a Facebook group where each thread seems to have three reasonable people and a hundred kids screaming: "yes it is, no it isn't, hey look something shiny!"
Title: Re: So ... 3d Printers....
Post by: Howard_Casto on November 29, 2016, 11:29:54 pm
Yeah I'm swaying back in the i3 direction due to the amount of parts and mods available.  Anything from dual heads to new frames.  I'm glad you said something about the auto-level because on the aforementioned facebook page everybody swears by the auto-level version.  It didn't make sense to me how a cheap sensor would help. 

I'm not interested in abs except for special projects due to the fumes alone.  I'm thinking it might be better to keep it in the house as it looks a bit delicate. 



I hear ya.  As per usual I ask in this forum and somebody who knows what they are talking about answers.  Funny how that works around here.  ;)

Keeping it inside is a very good idea. Climate controlled is best as any temperature changes can mess things up. Even a draft can mess up prints, keep away from open windows or HVAC vents. Humidity can affect the filliment too but PLA and PETG are not too sensitive to moisture. Dry filliment is happy filliment.

We are lucky to have the BYOAC forum. Many forums are dying with people shifting to Facebook groups, etc which is a huge loss IMO.

Well I know I said gearbest is out, but it's back in.  They just had a new sale, 149 bucks shipped from LA.  I used paypal for payment and bought the shipping insurance for a couple bucks to protect myself. 

So:  [Smee]If anybody's not 3d printing... get here quick![/Smee]

http://www.gearbest.com/3d-printers-3d-printer-kits/pp_343643.html?wid=8&siteid=136649&utm_source=webgains&utm_campaign=GearbestUSA (http://www.gearbest.com/3d-printers-3d-printer-kits/pp_343643.html?wid=8&siteid=136649&utm_source=webgains&utm_campaign=GearbestUSA)

Pay attention to the warehouse because when they run out it switches over to China and they charge you an additional 30 bucks (not to mention the 4-6 weeks for delivery)

So now that I've ordered one and I've saved so much money, are there any parts/mods/ect you guys recommend getting?  Urls on stuff would be helpful.

I've gotta buy some filament as well.  I stumbled across a ebay store that was selling red and blue pla 1kg spools for a mere 10 bucks a spool.  I'm unsure why those filaments are so cheap while other colors can be upwards of 30 bucks.  I've gotta get black though as I'll be printing some stuff for my car.  Transparent is interesting as well.

I'll respond in some detail when I get home tonight and can use a real keyboard. But I would stay away from the cheap mystery fillimaent. It will only cause you grief. Hatchbox and Esun brand PLA have both been good for me and are on Amazon Prime. Makergeeks are not on Amazon but are one of my favorites and they do grab bag style deals for discounts but they pick the colors.

I'm using Amazon for most links since that's where I buy most but Ebay and Aliexpress (cheap but slow) are both fine sources.

My feeling is that most of the overheating issues people have are a combination of marginally sized connectors / wires and poor assembly.  I have to bet that Howard will have no issues with electrical assembly  ;) after that check things carefully during the first few prints for any overheating.  Also, I don't like running the bed too hot with the stock setup.  50 - 60 C is plenty for PLA and PETG.  ABS needs more like 100+ C which is pushing things for this unit and another reason to avoid ABS.  Make sure the wires to the hotend are secured with a strain relief to the corner of the X carriage. Otherwise things can loosen up and fall out of the hotend causing a thermal runaway. This comes up weekly on the Facebook groups at least.  Make sure the wires to both the hotend and hot bed are able to reach freely to all movement positions and don't get pinched or pulled too tight.  Zipties are your friend.

My must do upgrades:
Power supply.  The supplied unit is 20A with no fan.  It's undersized and poor quality.  Easiest to up it to a 30A with fan like these: https://www.amazon.com/gp/product/B00MAC9MO6/ref=s9_acsd_hps_bw_c_x_5_w (https://www.amazon.com/gp/product/B00MAC9MO6/ref=s9_acsd_hps_bw_c_x_5_w)
Also possible to use a computer power supply.  And some people run two power supplies, one for the hot bed and one for the rest.

Hotbed SS relay.  I use this one: https://www.amazon.com/gp/product/B01HEQVQAK/ref=oh_aui_detailpage_o05_s00?ie=UTF8&psc=1 (https://www.amazon.com/gp/product/B01HEQVQAK/ref=oh_aui_detailpage_o05_s00?ie=UTF8&psc=1)
This lets you bypass the PCB for the hotbed power, the PCB hotbed output is then used as a signal to the relay.  Really cuts down on the undersizing / overheating issues.

Hotbed electrical connection.  The plug / wires are a little undersized and it gets warmer than I'd like but has not failed or discolored on me so far.  Most straight forward fix is to up the power wire size and solder them directly to the board.  Easiest to do during assembly but since I didn't do it then and I hate to disassemble a working unit, I'm still working in this.

Hot bed springs.  The hot bed springs can scratch through the 'paint' insulation on the bed and short the bed.  Easy fix just add some kind of insulating washer.  I just cut up some plastic I had laying around.

Really recommended:
Hot bed surface.  Getting the plastic to stick well for the whole print time but still pull off when done is the eternal problem for 3D printers.  The right print surface is a big part of this.

The masking tape that comes on the bed will work for PLA but is kinda crap.  PLA will print pretty well with blue painters tape and an unheated bed. 3M tape seems to be one of the best.  Needs to be replaced every 10 prints or so (depends on how hard you are on it). Clean off any fingerprint residue, dust, etc with some rubbing alcohol before each print (true for most any surface). May help to roughen up the surface a bit.

My best recommendation here is to use PEI (Ultem). It's a type of plastic that has just the right amount of stick and release on a heated bed, at least for PLA and PETG. Leaves a very smooth surface on the bottom. No glue or other stuff to mess with. Most common PEI is a plastic sheet about 1/32" thick that you have to add adhesive to, often sold as a kit for 3d printers.   I prefer precut PEI tape I get from here: http://catalog.cshyde.com/item/3d-printing-materials/ultem-pei/36-3a-3d-866x866 (http://catalog.cshyde.com/item/3d-printing-materials/ultem-pei/36-3a-3d-866x866). Lasts for a lot of prints as long as you don't tear it up getting prints up. I have yet to replace my first piece. I've used a lot of different surfaces and PEI bets them all, works great and easy to use. Just wipe with alcohol before each print.

Decent tool to remove prints.  Lots of options but I like this one: https://www.amazon.com/ToyBuilder-Labs-Print-Removal-Tool/dp/B00VB1U886/ref=sr_1_2?ie=UTF8&qid=1480556021&sr=8-2&keywords=3d+print+removal+tool (https://www.amazon.com/ToyBuilder-Labs-Print-Removal-Tool/dp/B00VB1U886/ref=sr_1_2?ie=UTF8&qid=1480556021&sr=8-2&keywords=3d+print+removal+tool). It's cheap, thin and flexible enough to get under the part but not sharp so won't hurt the surface.

OK I better stop now.

Thanks Sammy that's extremely helpful. 

I think I've got an old atx power supply from a gateway of all things.  I'll have to check the wattage but it's small enough to fit on the chassis.  I have some nylon washers from another project that will fix the spring issue. 

In regards to the bed, I saw where one guy used glass that was roughed up with a dremel.  Do you think that would work?  I was thinking of maybe a mirror as I could monitor the underside of a print as it's printing. 

I'll go ahead and order the other stuff. 
Title: Re: So ... 3d Printers....
Post by: SammyWI on December 01, 2016, 08:10:27 am
Glass is a good choice for a print bed. Best is borosilicate glass that can handle the heat and stress well. Some people report using plain glass or mirrors without problems, others say those can shatter without warning.  Some people like to roughen up the surface but most print with some kind of glue on the glass. Hairspray is one choice but I had great results using PVA glue which is just the basis of Elmer's white glue. Elmer's purple glue stick worked great for pla and nylon on my old printer.  The downside of glue is  bit of mess and needing to clean it off prints and every 5 prints or so I had to clean the build up off the glass and start fresh. But PVA is water soluble and easy to clean.

Glass can be attached to the bed with binder clips so you can remove which is very useful. But the nozzle can run into the clips if you're not careful. You can also stick the glass down more permanently. Heatsink tape works well from what I hear and helps the glass get up to temperature faster. Speaking of that, you will probably have to take a bit more time heating the bed and remember the bed temperature sensor is on the bottom so the glass temp will lag behind the indicated temp.

The big issue that made me switch away from glass is that an inductive sensor needs metal to work. The glass adds more distance to the Aluminium heat bed and it's hard to get a sensor to work for that extra distance. I know I said don't get the auto level version but that is only because Anets version sucks. A DIY upgrade is very worthwhile and is one of my favorite things about my new printer.

Awesome thread.  I've been on the fence about getting a 3D Printer and I think I may finally pull the trigger this season.  Merry Christmas to me!  I'm looking at custom brackets, project enclosures, etc.

I've used mine more than I thought I would.

It's strange.  Several times now I've needed a small part that I would usually have cut out of wood or bent up metal to make.
Rather than getting out the jigsaw to cut it (poorly), drill and bits to drill it, It's easier to just make the thing in tinkercad and print it out.

This weekend I'm going to be stuck at a Christmas party when I'd rather be at home watching football.
I made a tiny stand to hold my phone up at a good viewing angle.  It only took 10 minutes to design and 6 minutes to print.
I printed out extra for the office, car, coat pockets.

What I've found to be the most useful tool is a digital caliper.
Adjust to size of part needed>look at number on display>drag object in tinkercad to that size

I've also started printing thin partial parts to test fit, as part of the design process.

Well I'm having to come to terms with the fact that in my left eye at least, my eyesight isn't what it used to be.  I used to be really good at fabricating fiddly bits for projects but now I'm constantly screwing stuff up.  Depth perception plays more of a role in making things than you would expect.  Hopefully when I get glasses this spring it will help, but in the meantime I think I would actually save time and money by designing stuff in the computer and then printing it out.  I guess all those years learning 3dsmax and autocad for 3darcade wasn't wasted. ;)

I'm also very excited about the auto gear and sprocket plugin for google sketchup.  Being able to design and print out a working gear box seems very useful. 

A digital caliper is on my short list of things to buy.  I wanted to see if harbor freight had any deals. 

I will get an auto-level kit down the road, but I want to learn how to use the thing first.  I figure manual calibration knowledge will help me troubleshoot any problems with the auto-level system.  Believe it or not I probably have pyrex or possibly some safety glass around here somewhere.  Sometimes I feel like WV is just some elaborate Truman Show, only mixed with Sanford & Son.... and Cops. 

Oh btw... companion projects: 

One of the first things I want to build is a 3d scanner.  Sure enough there are thingiverse plans for a small scanner.  I want to up-scale it so it can handle larger objects though.  I also spent all night watching some guy rube-goldberg together a filament extrusion machine over the course of several months only to wake up this morning and see another guy had designed one that I would have made... vertical with the  hot end gravity fed, which solves 90% of the consistency problems because...well...gravity is a constant.

If I haven't mentioned it yet check out www.thingiverse.com (http://www.thingiverse.com) for models shared to print.

Nothing wrong with using a simple switch for the Z home. I would recommend modding it like this: http://www.thingiverse.com/thing:1479176 (http://www.thingiverse.com/thing:1479176)
This lets you level the bed seperatly from adjusting Z home position and gives you a fairly precise adjustment. Also make sure that you lock the bed into position after leveling the corners. I think this area tends to move during printing and the wing nuts supplied may not have very good threads.  Kits come with extra M3 nuts so I'd use extras as jam nuts.

A better fan duct is a good early mod.  Plenty to choose from, I used this one: http://www.thingiverse.com/thing:1823404 (http://www.thingiverse.com/thing:1823404)

You'll see a lot of printed frame braces to support the points where the y axis (hotbed) belt attaches. I don't know if the frames tends to bend there or not but it seemed like a reasonable thing to reinforce at assembly.  IMO the printed braces are a lot of material to solve a simple issue.  I liked this idea: http://www.thingiverse.com/thing:1517525 (http://www.thingiverse.com/thing:1517525).  But I just ran the extra threaded rod as close to the belt attachment as I could without printing a special belt attachment part.  Just had to drill some holes through the front and center frame pieces, the back frame piece already has an oversized hole to use that can be covered with some fender washers. Again, best to do at initial assembly.  You do risk cracking the acrylic parts drilling the holes but I had no problems going slow with light pressure and scrap wood backing.

3D scanner is on my list of projects.

Funny you should mention gears.  I am a mechanical engineer and I design gears as part of my job. Surprised to hear that SketchUp has a plug in for gears. Last time I tried to look at Sketchup for a friends project it drove me nuts with how imprecise it was.  Maybe it's changed. I do have some gear models shared at Thingiverse under the username Drawcut.

For frame stability is was just going to mount the whole thing on some laminated wood.  I think I have part of a countertop lying around somewhere. 

I think I've got everything ordered.  I still need to order a spatula to remove prints and unfortunately spatula city is no longer in business.  ;)  I was looking into pcb milling and some people have add success using the i3 to mill with a large dc motor and spindle.  I've probably got that crap lying around.  I'm also looking into 3d scanning... it hasn't progressed much since the last time I looked.  A laser pointer/camera combo still seems to be the way to go.

I ended up putting mine downstairs in our spare bedroom closet. I am not sure if your is going to be as loud as mine. The Printrbot Simple Metal gears have a really high pitch to them, gets super annoying after awhile.

(https://s19.postimg.org/y8jyt55pr/0719161741.jpg) (https://postimg.org/image/y8jyt55pr/)

The Printrbot has a built in auto level but I had too many issues with it. I just took out the auto level gcode command and threw in some nuts and screws and just manually adjust it. Ive never had leveling issues since.

As mentioned earlier in the thread Hatchbox PLA is my go to filament. Can get it shipped in a couple days through Amazon Prime and consistency has been good.

I was going to get a glass build plate but once I upgraded to a heated build plate I stopped having warping or peeling issues. Now I just slap on some painters tape and I am good to go. (Image shows kapton tape instead, this is when I first upgraded the build plate size, pre auto level fix)

Scanning is also my next thing but the ones I really want are like 5K and up.

I have mine mounted to some 3/4" plywood I had laying around. I cut pieces of rubber gasket material to put between the printer and the wood then got some stick on rubber feet for under the plywood. Works well and probably helps dampen noise and vibration.  I used this stuff but got it at a local hardware store: https://www.amazon.com/Danco-59859-Rubber-Packing-Sheets/dp/B000PS9Z8A/ref=sr_1_10?s=hi&ie=UTF8&qid=1480866712&sr=1-10&keywords=rubber+sheet (https://www.amazon.com/Danco-59859-Rubber-Packing-Sheets/dp/B000PS9Z8A/ref=sr_1_10?s=hi&ie=UTF8&qid=1480866712&sr=1-10&keywords=rubber+sheet)

The Anet A8 has been quieter than my Printrbot original. I have it in the basement in an unfinished workbench area.  But it is directly below our bedroom. My wife says she can't hear it at all in the bedroom.  I can just barely hear a few bits if it's quiet and I concentrate but it doesn't bother me for sleeping.

I just got the  heated bed plug worked out.  It is a 6 pin plug with only 4 used.  The two outside plugs are bed power, the two innermost pins are for the thermistor. But the two unused pins are soldered in to the heatbed just unused on the wire side of the plug. (Somebody on a FB group saw this.) So I added two connectors and wires back to the Mofset and I now have 4 wires for heating the bed and the plug sides and wires have gone from warm to the touch to room temperature. Soldering the wires directly is still probably a better way to go but I really didn't want to take the bed off since it has been printing so well.  The bed plug is a JST VH series (or a copy of one). I got parts from Digikey (https://www.digikey.com/product-detail/en/jst-sales-america-inc/SVH-41T-P1.1/455-1319-1-ND/608888 (https://www.digikey.com/product-detail/en/jst-sales-america-inc/SVH-41T-P1.1/455-1319-1-ND/608888)).

Another project I've been considering is a laser cutter / engraver. I won't be able to get the power to cut very heavy material but I wonder how much I could cut with slow speeds and multiple passes.  My old Printrbot may be donating parts.

So for anyone interested I assembled my anet the other day.  It took two afternoons, but some of that had to do with the fact that I stupidly used the instructional videos on the site I ordered it from instead of the ones on the included sd card.  These bad boys are getting revised faster than the vendors can keep up with.  It wasn't particularly hard, but if you want to save yourself a big headache, go ahead and take all the nuts and tape them in place on the slots in the acrylic panels to hold them in place.  I'd say 50% of my time was used up trying to get the little sobs in place.  Cable management is also an issue.  The included wraps work, but they are kind of ugly and some of the cables are waaaay too long, so you have to fold them up and manage them somehow.  I'm thinking of re-routing mine around the board so that it looks better.... perhaps I'll run them behind the board to take up some of that slack.

Overall I'm extremely impressed with the build quality for something so inexpensive.  There are a couple of head scratching design flaws, but they can be fixed easily by just printing out parts.  I would show an example print, but like an idiot I somehow managed to order 3mm filament instead of 1.75mm.  So to be continued I guess.

Nothing major.  Third generation Camaros don't have much in the way of cup-holder options, so I'm going to design one for my car.  Hopefully if it turns out well enough I can distribute it to keep people from cutting holes in their center consoles.  There are some extra holes on the extruder carriage, so I'm going to try and design some quick-release accessories like a plotter pen and maybe a pcb mill. 

I've got a couple of arcade related ideas, but really important.

Decided to take the plunge -- for $154 shipped from California, had to give this one a try - the bedsize is a bit smaller than the Anet A8 (200mmx200mmx180mm) but a good bit larger than the monoprice mini. Was going to wait for the A8 to get replenished in LA but came across this one for about the same price so decided to order rather than wait before I spent the $ on something else  :laugh2:

Now to find a good place to order some filament from (it comes with a small roll (250g) for setup but I'm sure that wont last long !) -- Note to self be sure to get 1.75mm not 3.0mm  ;D

Post by: BadMouth on December 30, 2016, 09:43:36 am
Looks like a hell of a deal to me.  I ended up spending another $10 on a spool holder like that to go with my monoprice mini.

I also picked up a little needle nose pliers & sidecutter set at Walmart for 3 or 4 bucks.  Also had a flexible scraper.  I already had this stuff, but it's nice to have a set that stays with the machine.

Post by: JDFan on December 30, 2016, 10:59:16 am
OK - couple questions for those with a printer already -- How long does a roll of filament tend to last ? And has anyone used the monoprice filament - Is it good quality ?

Asking because Monoprice has a pretty good deal on the filament right now ($19.99 per 1Kg roll of most PLA ) and till the 31st they have a 15% off code (maker15) that makes it $16.99 a roll but the thing is if you purchase 1 or 2 rolls the shipping is about $12 but if you get 3 rolls it makes the free shipping cut off and shipping is free which means the 3rd roll only costs a couple bucks and seems like it is what I should order but will 3 1Kg rolls be too much ? :dunno

Total cost breakdown :

Quote
3 rolls @19.99 + Free shipping = $59.97 - $9 code Maker15 = $50.97 or $16.99 per roll
2 rolls @19.99 + $12.44 shipping = $52.42 - $6 code Maker15 = $46.42 or $23.21 per roll
1 roll @19.99 + $11.39 shipping = $31.38 - $3 code Maker15 = $28.38 per roll

How long a roll will last is pretty hard to answer because everybody is printing different things / shapes / sizes, etc.  I found a couple of places that try to answer that question:
http://www.soliforum.com/topic/1409/how-long-will-a-spool-last-how-much-can-i-print/ (http://www.soliforum.com/topic/1409/how-long-will-a-spool-last-how-much-can-i-print/)
https://www.makerbot.com/media-center/2012/02/24/a-matter-of-scales-how-much-can-you-print-with-a-single-1kg-spool (https://www.makerbot.com/media-center/2012/02/24/a-matter-of-scales-how-much-can-you-print-with-a-single-1kg-spool)

IMO, buy the three spools. If you enjoy 3d printing at all, you will end up buying a lot more than that in the long run.  Plus it's always nice to have a variety of colors to use. I have not used the Monoprice filament but it is a brand that I have heard others using and those prices are good at the 2 roll option and very good at 3 rolls. For one roll $28 is fairly expensive for basic PLA.

Now I do need to go dig up that thread on printing a Star Wars control yoke. That's been something I have wanted to do for a while but have never gotten around to.

Yeah - I was surprised the price had come down that much recently - they were quite a bit higher when I was looking a few months ago so was hard to not order when I came across it.(esp. since they had stock in CA rather than having to wait for shipping from China !) Completely agree about having a set of tools specifically for the printer (otherwise it can get hard to find the correct one when needed - since I tend to leave tools laying where they were last used at times  :cheers: )

Thanks for the response - interesting links - seems it goes a bit further than expected on a roll - but agree having the extra never hurts and I can see it becoming a matter of getting all the right colors for each project. Went ahead and ordered the 3 rolls so should have plenty to get started and play with for awhile  :cheers:

So 1.75mm pla is on the way.  You know I think that might be the thing keeping these rigs from going mainstream.  My local hardware store sells some rep-raps and such, but you can't buy filament.  They need to keep filament in stock at the hardware/electronics/hobby stores.

Printer arrived today along with the order from Monoprice with the 3 rolls of filament - Now just need to find the time to put things together. ( Busy laying tile this week - so not much free time )

Opened the box after getting home and it actually seems to be decent quality for the $154 shipped - will know more after assembly. ( noticed the price went to $209 from the same seller, when I went to check the order status yesterday - glad I purchased when I did ! )

I'm hoping this thread re-motivates me. Bought a new nozzle and extruder. only found the time to install the nozzle. Lost motivation/time to finish leveling the bed and test.

Saw a interesting article that suggests that dusty filament can increase clogs. saw that some folks install gizmos to wipe off the filament as it enters the extruder. Go figure.
I'll just be happy once I start printing again.

I wouldn't recommend using anything that will leave a residue on the filament.  Could easily cause printing issues or clogging.  Don't leave your hotend heated up for long periods when not printing.  If your hotend has a cooling fan, leave the fan running after shutting off the hotend heater until the temp drops below about 40C.  Both of those things will help prevent clogging.

Post by: Howard_Casto on January 10, 2017, 02:23:28 pm
Ok so I finally got my filament.  I'm running into problems.  :(

The first problem was that I couldn't get the printer to take the filament... apparently the filament guide mechanism is designed poorly, so I had to remove the fan from the extruder (which essentially disassembles the whole extruder assembly), feed it into the hot end, and reassemble.  Then I had some really bad problems with leveling... I finally got it to an acceptable level. 

Ok now for the final problem.  The printer is printing the first layer of a file perfectly, but once it needs to move up, it jumps waaaay too far up and I've essentially got silly string from then on.  Now I haven't modded it or anything, this is the stock printer with the original firmware installed and I'm trying to print from the test files on the included sd card.  Do you think the examples could be the problem?

I'll install the software and find a file later tonight, but if anyone has had experience with this I could sure use some help.... worked on it about an hour at lunch.

Title: Re: So ... 3d Printers....
Post by: Howard_Casto on January 10, 2017, 04:34:58 pm
So the sd card was corrupted, so that might be part of the problem.  I think CURA and/or the built in firmware might be the rest of the issue.  I tried some more prints and as per usual the first layer printed fine.  On the second layer it jumped up like an inch, so I'm not sure what is going on.  I used the included cura profile for my printer and I tried one of their models as well as one I converted... same problem with both.

Post by: 05SRT4 on January 10, 2017, 04:42:12 pm
Whats the layer height set too? I usually start with .2 mm.

Sounds like the firmware might be having issues, could always flash it with the latest version.

Also does it do the same thing on the 3rd layer?
Title: Re: So ... 3d Printers....
Post by: BadMouth on January 10, 2017, 04:43:23 pm
Post a screen grab of your cura settings.
(the ones on the left of where the model is displayed.)

If it is the settings and not a hardware issue, it could be that the layer height is set to something crazy high.
It has separate settings for the first layer height and following layer heights.

EDIT: was posting same time as 05SRT4....we're thinking along the same lines.

I've never had the layer height jumping issue but I would not be surprised if the installed firmware was corrupted. I'm pretty sure mine was as it would not accept an auto level command and would not communicate temperatures with Octoprint.  Flashing to the Skynet firmware fixed both.  Not sure if still true but when I flashed there was no original firmware files available so a flash to Skynet was one way.

ETA: After some searching I see a lot of people say the included SD card is crap and can cause this.  Using a different card seems to fix it.  Also the filament loading is tricky but after a few times it gets pretty easy.  Straighten out the end of the filament and you'll need to get used to where that tube is that you need to hit.  I also replaced the socket head screw they used for the part you have to press on with a hex head so that my thumb has a more comfortable piece to press on.

Ok, to reply. 

I'm using Cura 14.7, which is what the documentation recommends.  The layer height is 0.2mm.  Tried with a different sd card... it didn't help. I tried a rep-rap stl file of the maker bot mascot and things got weird.  First time it just set at idle and did do nothing, the next time it make noises like the printer was moving and the percentage meter went up, but nothing happened.  Then I tried two of the models I tried earlier... they are still doing the same thing.   The printer is acting weird.... like when I browse files I can hear the fan ramping up as I go through the menu.   Can Skynet be configured to not use auto level?  I need to print the sensor bracket before I buy the sensor.

Post by: Howard_Casto on January 11, 2017, 01:12:12 am
Ok more stuff. 

I tried a different slicer, it didn't help, so I think that rules that out.  I haven't been able to do anything via a usb connection.  Cura will connect if I force the port number and the printer will reset, but then cura hangs.  I've had similar issues with other software. 

Skynet includes the stock firmware for A8, but I'm afraid to install it.  I used it in avrdude with the verify option (surprisingly avr dude can connect?) and it comes back saying some of the bytes don't match.  I checked what is supposedly an updated version and it doesn't match either (shows the exact same byte differences).  I'm just scared that I'll brick the thing because there are multiple driver boards and I'm not 100% sure which one I have.

Also Skynet does not have to use autolevel. You would just ignore setting up any z offset for the sensor, set z height manually and don't use the gcode for autolevel in your slicer.

Yeah I've got a set of those as well.  What worries me is the fact that I can't get the bytes to match via verify with any version of the firmware.  I *think*  I dumped the firmware to a hex file for backup, but if there is any kind of strange bootloader or funny business going on it could corrupt the dump.  I've seen tutorials on how to use an uno to write directly to the serial port in case of issues after a bricked unit, but I would like to avoid that.

Did you flash yours with avrdude or arduino's toolkit?
Title: Re: So ... 3d Printers....
Post by: SammyWI on January 11, 2017, 02:32:48 pm
I flashed using what was included with Skynet, arduino I think.

What are you comparing to match bytes? Just a non programmer guess but if you are comparing the fw that came on your board wouldn't you expect the bytes to be wrong if that fw was corrupt from the factory?
Title: Re: So ... 3d Printers....
Post by: Howard_Casto on January 11, 2017, 02:46:41 pm
Well yeah that's true, but what concerns me is that it finds errors so early on... like in the first 30 bytes or so... that could be the boot loader.  I opened them up in a hex editor and they look nothing alike.  Mind you they are compiled, so a different revision would change things drastically.

I mean at this point it isn't working and I've heard very few complaints about Skynet, so I'll probably take a chance and update it tonight, I just don't want to have a gigantic project of getting things re-flashed if it doesn't work or the boot loader is corrupted, ect.

Oh and this morning just to make sure it wasn't a mechanical issue I used the position commands within the printer and the movement is dead on, down to the millimeter, so that rules one more thing out.  It's really odd, it's almost like it can't read the g-code properly, because everything else seems to work ok.

Post by: Howard_Casto on January 11, 2017, 10:39:20 pm
Alright guys, I got it sorted.  Thanks a bunch for the help.  Part of the problem was on my end and the other part was on the printer's end. 

Ok now keep in mind that I can't see well yet, so don't make fun of me too bad.  It turns out my hotbed leads had a single strand of the braided wire touching and it was causing the sensor to go nuts.  The thing is, the crappy firmware that is included with the printer doesn't really have any status messages, and thus why some of the models I sliced myself yesterday were just hanging... the bed never read the correct temp so it just sat there heating up. 

Skynet also hang, but it hang at the "heating" message and the temp seemed off to me so I figured it out.

That still didn't explain the huge z-axis jumps though and why I couldn't connect the printer via usb in cura... that was all corrupted firmware. 

So yeah, for those that order one of these, just skip some frustration and install Skynet.  They even have a config file for the non-autolevel  version so if you are going to buy the better sensor later on like me you are still covered. 

The test cube turned out great.  No gaps, no distorted edges, ect. and keep in mind I had to pick the thing up to fix that wire and didn't re-calibrate afterwards.  I have a few issues to sort out though.  I couldn't figure out how to set the z-offset as the instructions are for the auto level sensor and some of the menu options aren't in the new firmware anymore.  So it's like .1mm off.... it still prints fine but if there is a bubble in my tape or something it drags.  Speaking of dragging... the cooling neck that goes on the fan drags really bad... I had to take it off to print.  I figure this isn't a big deal as I'm going to print a new one anyway.

Glad to hear that you got it running. You don't need to set any z offset in software. Leave it as is and adjust the nozzel to bed gap by adjusting the z switch height or the bed height. The cooling duct height is probably off because the hot end height can be installed at different heights and it may be a bit high. Be very careful if you adjust it - the threaded tube is not strong and many people break them. But they are cheap to replace. Most people print a different cooling duct but you may find that the models out there will also run too low unless you adjust the hot end or adjust the duct model. You can do plenty of printing with no cooling duct.

I guess I'll just keep posting my progress in case someone else wants to takes the plunge on this particular printer and wants some tips.

So I printed out this:

http://www.thingiverse.com/thing:1954001 (http://www.thingiverse.com/thing:1954001)

It replaces the stock fan duct and it fits much better. It latches on the tab on the left wall of the fan, so it won't fall off anymore.  It also sets a few mm above the hotend and just blows the air downwards, so it's far less likely to hang. 

I'm done printing for the night so I'll report back if it works well when I print the next upgrade.  I think I'll print the power supply cover next because not getting electrocuted = good.  Also it might be nice to have a switch to turn the thing off.... I currently have to unplug it.

Well yeah and for normal printing I'll just adjust the screws on the hotbed.  The thing is I would also like to experiment with a glass bed and perhaps print out a spindle attachment so it would be nice to be able to throw some g-code in there to change the offset.  I might not even bother with auto level.... it seems to do ok as-is. 

As mentioned, the duct I printed out is about right, so that much isn't an issue at least.

Glad you got it going. Having a 3d printer is 90% figuring out how to use it and making adjustments and 10% printing.

The printer I had was all about the Auto level feature but after awhile it just started causing more issues. I ended up removing the auto level Gcode and just put nuts and bolts on each corner of the bed. I rarely need to adjust anything once I get it dialed in.
Title: Re: So ... 3d Printers....
Post by: Howard_Casto on January 13, 2017, 11:26:01 pm
Heh yeah tell me about it.  I'll be spending the next day or so printing out parts to make the printer better.  The duct was an instant improvement... much smoother texture on the objects now.  I just printed out z-axis bushings to fix a flaw in the design (z-screws were too short).  Right now I'm printing out a top-mounted spindle holder since the one that came with it is basically a stick and the spool wobbles like crazy when printing (which has to screw up the precision).  Then I want to design and print some tool holders since apparently fiddling is going to be a thing any time I change anything. 

After all of that I'll be able to trust it to print with a good degree of precision. 

I still need to print a power supply cover and motherboard cover as well... I might have to design my own for that as I can't find one that I like.

..... I just printed out z-axis bushings to fix a flaw in the design (z-screws were too short).  ....

This comes up on the FB groups a lot.  If the ends of the Z axis threaded rods don't quite reach to the holes in the top piece it's almost always because coupling to the Z motor is installed wrong.  It usually comes from the factory with the coupling pushed too far down on the motor shaft, and people often push the threaded Z rod too far in the top.  Both the motor shafts and the threaded Z rods should only be inserted about 5 mm into the coupling, then the threaded rods will reach into the upper holes and the coupling is free to flex correctly.  Also the top of the threaded rods do not need to be tightly restrained.  The smooth Z rods hold the alignment, small movements of the threaded rods will not hurt anything and trying to tightly restrain them can cause binding.
Title: Re: So ... 3d Printers....
Post by: Howard_Casto on January 14, 2017, 12:31:55 pm
Nah it's a flaw in the design.  Even with the couplings raised to where there is just barely enough contact to grip onto the motor shaft and z screw the screws just barely make it into the upper holes.  I mean it's so little that if the axis were to have any kind of strain I would be afraid of them popping off.  Before I installed them the right z screw had a tendency to lay crooked and when the z axis got towards the top it squeaked horribly....I think it was rubbing on the frame.  Now it moves much more smoothly and their isn't any squeak.  The bushings I printed don't bind the screws as there is just a little bit of room.

Printed out a new spool holder that mounts to the top of the unit and a power supply switch.  I think I might reprint both later on because they weren't designed real well.  I'm learning that blindly printing out stuff on thingiverse isn't always wise.  I suppose I'm going to have to download a 3d cad program and knock the rust off my old school skills.

Bah!  Another day, another problem.  I was printing out a pcb cover, which is the last part I need to print and shortly after printing the bottom layer the printer throws a thermal runaway error and aborts the print.  I'm trying again, but I'm not too optimistic. 

The interwebs tell me that a drastic change in temperature will do this, but I didn't notice any change.  It certainly didn't overheat at least.  Re-checked the wiring and it looks secure and in tact.  Could my new fan duct be cooling too well?  Is there a way to stop the fan on a running print?  (Other than unplugging it of course).

I am not familiar with the printer you are using but on mine since I am using OctoPrint software I am able to adjust or turn off the fan mid print from my phone or PC. When connected to my PC and using simplify3d (slicer) I am also able to make the adjustments mid print.

But I doubt its because the fan is cooling it to fast. I would recommend checking the hot end and heated bed's thermistor, it may be loose or out of place or bad. Its a good idea to pick up a cheap laser temp gauge and use that to confirm the hotends actual temps.
Title: Re: So ... 3d Printers....
Post by: Howard_Casto on January 15, 2017, 04:44:28 pm
Well cura has a little status window and it has a text box.... I'm assuming I can use that to send commands, but I don't know what the command is to stop the fan.  It seems to be doing ok this time.  The only thing I did was put a big old fan on the power supply just in case and cinched up the wires to the hot end a little better as they were hanging below the fan duct. 

It's very annoying... one of those watched pot deals.... It was printing fine last time so I went in the living room to watch a movie and it crapped out on me.  Right now I'm on my computer anyway and wouldn't you know it... no errors.  I don't mind checking in occasionally, but this is a 6 hour print.    It's about halfway done, so hopefully it'll make it this time.  The solution for rapid cooling is to insulate the hotend, so I'll look into that.  And of course overheating just needs more fans, so I'll go through my junk drawers and start throwing every 12v fan I have at it.

While I'm waiting for this to finish I took a look at tinkercad.  it's surprisingly robust.  The only thing I don't like about it is there doesn't seem to be any way to work on models at the vertex level or the ability to delete/add/weld vertices.  I'm old school.  I usually plop down the basic shapes and then do all of the detail work with vertices.  I want to try one or two projects with it though.  No having to install a bloated 3d modeling program is a big check in the pro box for me.

I went through the included tutorials, then a few from this youtube channel: https://www.youtube.com/playlist?list=PLt4JWLrDaOYmjyhE08HbNdsHMGKAmX6jG (https://www.youtube.com/playlist?list=PLt4JWLrDaOYmjyhE08HbNdsHMGKAmX6jG)

With that, I've been able to pull off everything I can think up, except for complex curves.

The only annoying part is that every single thing you do is recorded in the file, so designs you've worked on a lot and redone parts of get so complicated that they take longer to load and sometimes get glitchy.  You can work around this by saving individual pieces as stl files, then importing them into a new design file.  Then they only show up as one shape instead of all the shapes & changes that went into making them.  Of course you can't undo or ungroup the parts that went into it.

You can also copy and paste from one design to another, which is helpful.

EDIT: BTW for some reason I can't access the drop down menu to change the snap grid size on the new Beta version (lower right corner of grid area).
         I can click on it, but the options are always hidden behind the tool panel or right edge of the screen.  Could be the 1600x900 resolution on my laptop.
         If you have the same issue, you may want to use the Legacy Design option.

I agree that a cooling fan is very unlikely to cause a thermal runaway error.  I'd check the temp sensor wiring very carefully.  After that, some of the Skynet releases have had some bugs.  I'm still on 2.0 because it works for me and I hate to fix what's not broken.  2.3 (or 2.3.1) seems to be pretty good from what I've read but some of the in between versions have had reports of thermal runaway errors.

Post by: Howard_Casto on January 15, 2017, 10:02:52 pm
I think it was just glitching out for some reason.  I'm currently running it via usb cable and I think when my pc gets busy it is sending odd data or something. 

The latest print turned out just fine and I checked the print every 15 min or so and there was never a fluctuation in temp more than a degree or two.  I checked the wiring the whole length, even removing the covering and I couldn't find any kinks or breaks. 

Anyway my pcb cover turned out great.  As per usual there was a design flaw in the author's design.... the box hit the right bolt on the z limit switch, pushing it down, so I had to take it off and dremel out a small hole.  It looks nice and tidy though.... I'm only hoping the vent holes are enough to keep it cool.  I'll probably mount a pair of fans to the outside just in case. 

Btw.... I've been using painter's tape on the bed because the included stuff sucked and I have a real hard time removing some prints.  My tape is ruined every two or three jobs.  I was thinking maybe contact paper or something.  Are there any pre-made covers out there that actually work?

As annoying as peeling tape of every other print its been the best for me. I just get the really thick cuts so I only need to do a few strips. I can go 4-5 prints before changing it out.

They had flexible sheets you can buy, I used one for a bit but eventual stopped when then 1st layer wouldn't stick anymore.

First layer sticking (and later releasing) is one of the biggest issues. I've used a lot of surfaces and I have found PEI to be the best so far with PLA or PETG. You can get PEI kits from Amazon or EBay that have a 30 mil sheet plus separate adhesive sold for 3d printing. I personally like 3 mil PEI tape from C S Hyde. Lasts for many prints with just a quick alcohol wipe before each print. Eventually gets beat up to need replacing. I have not yet tried the specialty print surfaces like Printz but the reports seem to be no better than PEI at higher cost.
Title: Re: So ... 3d Printers....
Post by: BadMouth on January 16, 2017, 12:15:51 pm
I've easily done two dozen prints on my current sheet of PEI and have no plans of changing it anytime soon.

I did have an issue once where it turned white and was ever so slightly puffed where the last part was stuck to it.
I do not know if it was that I was experimenting with higher temperatures, that I stretched it slightly while removing the part, or what.
It's just enough that if I print a big flat part face down and you hold it up to the light at just the right angle, you can see the outline.
This has only happened once and I'm still using the same sheet.  Just been too lazy to clean all the adhesive off and I haven't needed to print anything big and flat that needs to have a perfect shiny smooth surface.  Discussion here if interested: http://forum.arcadecontrols.com/index.php/topic,151479.msg1597116.html#msg1597116 (http://forum.arcadecontrols.com/index.php/topic,151479.msg1597116.html#msg1597116)

Other than that once instance, I pretty much consider PEI to be the permanent bed and not a consumable.

Well the smooth surface is one of my concerns.  Right now it is quite noticeable that I'm printing on tape because you can see the lines.  With what I'm printing right now it doesn't really matter, but when I start printing stuff out for my car it would be nice to have a smooth surface, or at least a uniform one. 
Title: Re: So ... 3d Printers....
Post by: Howard_Casto on January 18, 2017, 01:45:19 am
I saw a youtube video where someone used a butane mini torch to smooth pla prints.... I might try it.  Anyway, I figured out the z-offset.  You just want to throw a G92 in your starting g-code. 

Let's say you want to print on some glass and it's 10mm thick.... you would add the g-code:
G92 Z-10

That tells the printer that the current z-position is -10, so before printing it's going to move up 10mm to get to 0, which will be on top of the glass. 

So I need to read up on g-code as my 3d modeling training was more on the artistic side than the industrial.

when I start printing stuff out for my car it would be nice to have a smooth surface, or at least a uniform one.

When I first got my printer I thought I could pull off a nice smooth surface on the side facing the print surface.
I have since given up.  I can get it pretty smooth, but you can still see the path the printer took.
Getting something finished looking enough for a car interior without finishing in some other way is a pretty tall order.

When I had an 83 TransAm, I would cut panels out of textured ABS, clamp a guide across the corners and file the surface of the corners down until they looked like the factory panels.  If your Camaro interior looks the same, you'll understand what I mean.


So make anything cooler than a cube yet?

Post by: Howard_Casto on January 24, 2017, 10:43:57 pm
Well the idea was to cook each flat side on a hot plate for a second or two to melt everything flat and maybe use a torch for curves, but I think I'll experiment on reject parts first.  If all else fails spraying it with some filler primer and painting isn't a big deal. 

In previous cup holders I've used the excess of a midway 27" crt bezel from happ.  The stuff is a dead ringer for the plastic texture on the center console, but I think I'm about out of it. 

I've printed a bunch of stuff, but not much for fun yet.  I printed out a cover for the pcb and some bushings for the Z axis. I designed a couple of tool holders for the included kit that snap to the top.  I also printed off a spool holder that mounts to the top from thingiverse, but it kind of sucks so I might make a new one.  Other than that, I printed the Nintendo logo (small test size for a HUGE sign) and I made a little mounting box for a wifi extender that doesn't get good service unless I mount it in the window. 

I saw a Shao Kahn model from mk9 on thingiverse... I want to print that and paint it.  I had this idea to print out control panels for candy cab buttons/sticks.  I did some tests and with a 100% solid print it's probably stronger than most plastic madcatz sticks. 
Title: Re: So ... 3d Printers....
Post by: Howard_Casto on January 30, 2017, 09:23:31 pm
Yeah so I've been experimenting a little.

I found a plotter attachment on thingiverse for the i3 in which you had to remove the cooling fan.  I modified it so that it bolts behind the fan instead.  Sorry I should have taken more pics, but here is the first test before I dialed all the settings in.  As of now it has the accuracy of a black and white printer for the most part.  I'm still trying to keep the pen from dragging when it first starts printing, but other than that, it works.  The key to doing this is to save an additional machine profile in cura and change all the settings for the plotter.  Then switching back and forth is as easy as loading profiles. 

The next step is to modify the plate to make it a universal mount.  A dremel extension and vinyl cutting drag knife can work via the same principal for 2d cutting.

So I thought I would give a glass plate a try.  Thus far glass sucks.  I'll try to tweak the settings one more time tomorrow, but even with a bunch of glue down on the bed it's just sliding all over the place.  So I guess I'll try some of the ready made sheets you guys suggested as the parts are sticking to blue tape so bad that I fear I'm going to warp the bed removing prints.
Title: Re: So ... 3d Printers....
Post by: Howard_Casto on February 02, 2017, 09:57:41 pm
Bah! 

Never mind, the glass is actually better, I just goofed a bit of g-code.  Printed out the little makerbot keychain and he turned out pretty good.  You can make out most of his buttons and stuff, so I call that a success.  I need to lay off the glue stick a little next time, but I actually managed to get a flat edge on the bottom without any path lines.  He pulled off the glass a lot better than the tape, so assuming I can get this glue stick ratio down I think I'll stick with glass.

Yeah it's a pretty good printer so long as you understand that you'll be fiddling with it.  Like I kept getting thermal overruns recently... the solution was to zip-tie a set of wires down because the vibrations were wiggling the thermal sensor loose.  I've printed most of the hardware for my world of Nintendo cab with it and it has held up well.

Not a lot really.  I made a couple of tool holders since you need to keep all the hex wrenches and stuff it comes with for maintenance.  You also need to throw out the fan duct it comes with and print out a half circle one.  I printed a spool holder that sits on top of the unit to save space, but I think I want to re-design it a bit as I bumped into it and cracked it a bit.  I also printed a cover for the Arduino as it just sits there.  If you decide to get one I have links.  ;)

In terms of the power supply, it would aid in heating the bed faster (takes about 5 min to heat up) but it seems to be optional. 

There are a few things that aren't in the instructions that you need to do as well, like isolate the power wires and sensor wires to the heat bed and zip-tie them in place, ect.  I've learned that from half a year of trial and error.

Honestly seeing some of your guys prints made with this printer are comparable to my 700$ one. I think once you get the settings dialed in the quality is really good.

And I feel we probably spent the same amount of time testing and tinkering.

I ordered a couple rolls of Black PLA from AMZ3d (https://www.amazon.com/gp/product/B01BZ5ND8O/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1) for 16 bucks Prime free shipping. For the Price the filament print really well.

He had printed it on his new 3D printer, Thought it was pretty damn good!

I must admit i kind of fancy getting one to play with but will have to wait till the new year I think.

I admit itís a chance.  In saying that Kickstarter has been good to me.  I kickstarted the basslet and because the shipping company lost track of all Canadian orders, they felt compelled to recall the first order and send us another.  Only thing, a bunch of us still got the original order, so two for the price of one.  Wonderful little device, brought me back to the days when it was cool to just sit and listen to full albums and relax.  Itís quite immersive if a bit clunky to use because itís not wireless

Anyway......

Yots when your printer arrives I've got a list of stuff you need to print.  Some of it can wait, but you need a new fan duct and a power switch housing asap.  You might want to go ahead and buy/salvage a standard computer cord plug and a small on/off switch.  (I pulled mine from a broken pc power supply).  For some unknown reason the a8's don't have a guard over the ac voltage lines, nor is there a power switch.  So you need to print a guard with a switch and plug on it to make everything nice and tidy.  I think it's like a 20-30 minute print so It's a good thing to start with anyway.

So I don't know if I jinxed myself or what, but my power supply burnt out an hour ago.  I think the mosfet inside it blew but the power supplies are so cheap it probably isn't worth it to buy parts.  I can't complain too much as I've been running the poor thing for a year now.  I was running it pretty hard.... I'm printing the Nintendo sign for my world of Nintendo cabinet and it's been printing for about 15-20 hours non-stop. 

I'll have to get out my bench power supply tomorrow and make sure the boards didn't fry, but they should be ok as I did a visual inspection and the damage seems to be localized to the power supply itself. 

The one it comes with is 20 amps and doesn't have a fan.  They have one on amazon right now that is 30 amps with a fan included, which might provide a bit of insurance.  I might get some external mosfets to go with it since I have to re-wire anyway.  Honestly though they don't seem to be needed.  The main board hasn't even gotten a little warm since I bought the thing.

For the board?  No I still have the stock ones in place.  I think a lot of those melted connector concerns come from people not making sure the wires are properly connected because the main board, even with 20 amps running through it, it doesn't really get warm.

Then again I thought the power supply was ok as well.

For me personally, using Tinkercad was a mistake.
It's so easy and I've been able to make everything I've wanted with it. 
So much so that I never moved on to learning "real" 3D design software.
My purpose for buying a cheap little 3D printer was to motivate me to learn CAD software.  :lol

Title: Re: So ... 3d Printers....
Post by: Howard_Casto on October 26, 2017, 02:22:41 pm
Tinkercad is great for making functional parts, but not for making art, toys, or anything with compound curves.  So far that's all I've been using, but so far I've mostly been making hinges or project boxes, ect.  I saw a Johnny 5 R/C shell on thingiverse that I'm thinking of doing next, it isn't fully articulated, so I might brush up on my 3dsmax skills by adding full articulation to it. 

On the burnt out power supply front, I hooked it up to the bench supply and everything appears to be ok, so yeah, it was just the shoddy power supply.  So looking at it the transformer appears to have blown or something close to it.... I didn't even know that could happen.  That makes me think it was just defective, but it's been nearly a year, so I doubt its worth it to try and get my money back.

I might pull an old pc power supply to run it while the new one comes in... just so I can get this damn sign finished.  It's coming along nicely, but the slowness of printing something this big is killing me.  It takes approx. 2 hours per letter (1 hour per half of the shell) and it crapped out on the bottom half of the "d" in Nintendo.  So I've got about 10 hours of printing left plus however long it'll take to print the loop around the "Nintendo"  That's really the only thing that kills me about 3d printing, the speed.... it's just too damn slow.

^^Both of those ^^

You can speed up prints by doing less infill and adjusting the layer density and move speed, but stuff just takes a long time in general and fiddling with those settings results in a lower quality print.  It's basically slow because you have to print slow enough for the plastic to squirt out and harden before moving on to the next area.  To quote Scotty:  "I CAN'NA CHANGE THE LAWS OF PHYSICS!"

And yeah, you don't have to sit there and stare at the thing, but you need to be in the general vicinity of your printer while it's printing incase the print de-laminates from the hotbed or something goes boom, like what happened to me, ect.  They are far too dangerous to leave them unattended.  It's such a time sink I've seen some people setup an array of webcams so they can step out for a few and still check on things.  I'm thinking of building a metal box to put mine in which would help prevent a fire if something went wrong.  Hmm..... I wonder if the printer would still operate in a vacuum.... that would eliminate the fire risk. 

Actually the pieces I'm doing are pretty small.  Each letter is around 2 inches with 10mm height and they are hollow so I can install red plastic and back-light the whole thing.  One of the main things slowing this print down is I'm using the method where CURA can convert a jpg into a 3d height map, which gives the printer hundreds of points instead of smooth path.  It works really well for what I'm trying to do though and I'll post a step-by-step once I'm done.  If you are crafty about how to set things up and can do a bit of math, you can use this technique to make signs and project boxes and stuff without ever having to crack open the 3d software. 
Title: Re: So ... 3d Printers....
Post by: Howard_Casto on October 26, 2017, 11:14:29 pm
So I ordered a new 30 amp power supply and a mosfet for the hotbed.  Ebay sellers are frikkin scalping these things.  From china the mosfet is like 3 or 4 bucks.. but you'll have to wait 2 or 3 months for it to get here.  The US sellers are selling the exact same thing...they don't even bother to use different pics, only the price is around 10 bucks. 

For the record an ATX supply won't work unless it's an older model.  I tried to use one just to finish up my print but even with a few rails twisted together it kept triggering the overload protection when the hotbed kicked in and the whole psu shut down.  My benchtop faired better as it's made from a really old psu, but I know the wires aren't up to the task so I'll just have to be patient.

I didn't find it necessary.  The wires don't bind in any way and those chains add a lot of weight that could effect the nozzle.  You might want to get some of those mesh wire organizers though as the stuff it comes with is pretty ugly.  Since I'll have it apart for a while anyway I'm currently researching any upgrades that have come out since I built mine.  If I run across anything interesting I'll post a link.

Anything can blow up if you dont follow instructions.

Like the 2 printers I have, most if not all 3d printers are equipped with sensors which will catch if the hotend or heated bed start to over heat. If the Heat sensor (thermistor) dies or goes bad the system will stop heating and shut everything down.

Most issues ive seen is shotty / cheap PSU's, or the end user crimped some wires wrong.

I would say these are as dangerous as EZ bake ovens, mess up and you get burned. But do it right and you'll get some good tasting muffins.

I installed OctoPrint (Web Cams) on mine simply because I hated hearing the thing all night. I moved both of them to my garage. I can now see and manage my printers from my PC and cell phone, anywhere anytime. I get alert text messages if anything goes wrong (which is very rare). And its nice to give purpose to all these RasberryPi's collecting dust.

With respect... nope, ALL 3d printers are extremely dangerous to leave unattended.  Anything with a heat source shouldn't be left on while you are gone because heat can lead to fire... that's just common sense.  You don't leave the oven on while you are away do you?  How about your soldering iron?  Yeah it's that dumb to just walk away from something that is hot enough to melt plastic. Thermal runaway protection is not 100 percent reliable and if you are relying on it you are literally playing with fire as they only monitor the internal temps of the hotend and heatbed and now any fires on the bed itself from heating contaminated plastic or the psu.

Tell me more about this ... OctoPrint...

Download HERE (http://octoprint.org/download)

Easy to setup, only thing you need to edit is the WiFi settings, just add your WiFi name and password. Once all setup get the IP address of the PI and plug that into your browser (PC, mobile, anything connecting to that wifi)

You can setup access for outside your network but that involves some IT networking knowledge.

Plug the PI USB into your printer (Assuming that yours will have one) someone can confirm. I tapped my PI power from the PSU provided on the printers.

On my Printrbot I used the Pi Camera module, the quality is fine. On the Folger Tech FT5 I am using a Logitech C920 which works great when it stops trying to focus.

Quality lowered for gif:

I do agree that anything hitting 400 degrees should be watched, I guess I lost concern after 3 years of printing with no issues.
I should probably start looking at a all metal container or something, as always something bad is bound to happen.

3d printer is the one thing people are surprised I don't have yet.
but figuring out which one to get  :dizzy:

I do like the looks of this one and it's features.

That's supposed to be a good printer but keep in mind you are literally paying an extra 250 bucks just to print in three colors.  You might want to buy one that is mono color that can be upgraded at a later date.  I only say that because 3d printing isn't for everyone... it's quite tedious to make what you want and depending upon your time schedule you might discover that it isn't for you.

that thought had occurred to me also.
I may end up just printing a bunch of models I found online then letting it collect dust.
Or may learn to actually create something new on it or copy the stupid little plastic parts that occasionally break on my 20yr old car cause 20yr old interior replacement parts off a parts car are still 20yrs old. :)

I definitely want a kit so i can put it together.
I know the best way for me to learn how one actually operates is to assemble as much of it myself.

this is probably what i'm looking for then.

I had to buy an upgraded extruder in order to use Ninja Flex, the slightest gap would cause the filament to bend.
If you do get metal, carbon fiber or any abrasive filament remember to stock on on nozzles, its like running sandpaper filament through.

Cool beans man. 

My 30 amp power supply came in yesterday and I went ahead and printed the "d" and "o" even though the mofset hadn't arrived yet.  Considering the low cost, it might be a worthwhile upgrade to the anet/prusa printers.  I had it running about 3 hours non-stop and the power supply didn't even get warm to the touch.  I'm sure the fan helped, but regardless the whole unit just feels a bit safer now.

I'm an enthusiast, and the first thing that went through my mind when I saw those a few years back, was that's the next thing to be banned.  That said, for all the time they've been available, this is the first and only time they have been used for something like this.  It's also important to note that they aren't necessary to make a weapon behave like this...it just facilitates it.

Cool to see more folks playing with 3D printers.  I'm guessing you guys are starting to see now why very few make large 3D printed parts to sell.  Unless they are very rare and often sought after items, the design time, print time, maintenance and materials usually makes it not worth the effort, or the final cost of the item too high to be reasonably marketable.  But they are great for tinkerers, making personal "one-offs" and prototyping for other manufacturing processes.  Not sure we'll ever see machines based on this type of technology which would be well-suited to replace the more standard methods of production.

*sigh*

I made a lengthy post in response to that, but I don't want this thread ruined so I deleted it. 

Anyway....

I agree that 3d printers will probably never replace more traditional manufacturing methods.  What I can see happening is that 3d printers eventually become so turn key that manufacturers might send you an stl to print out when you break a knob off your dryer instead of sending a replacement part.  I eventually see them installed as a vending machine in Lowes/Home Depot.... right next to the key machine.  It's good to print out a rough shape for a casting project or something like that.  I believe someone is selling a wax filament now.... that'd be great for casting jewelry and gears and stuff.

I tend to think that the FDM process will never really be that autonomous.  I have an expensive unit, which I use exclusively for prototyping.  It prints perfect parts, and did so straight out of the box.  But geometry plays a huge role in what needs to be done after.  Some parts pop right off the raft, and some are a nightmare to release.  Support structures can also be a major issue.  There are just too many variables, too much post-print work, and the process simply takes too long for something like a vending machine.

But for something like you mentioned at the end, absolutely!  That type of application is where these machines really shine.  I would imagine that a wax filament model would be really easy to clean up and make a very nice master for molding.

You aren't kidding.  Looks like they spent a lot of time and money to make a piece of scrap.

Based on some reviews, a better material for lost wax is found here (http://machinablewax.com/product.php?product=52).  Lower melt-out temp, and supposedly leaves the mold much cleaner in the end.  The Moldlay material has been reported by some to leave a lot of charred residue in the mold.  Your mileage may vary.

I might try that. 

My mofset came in today.  I was looking at pre-made mofset holders for the a8 and I'm not a fan.  Most put it too close to the board.  The whole point of using one is to get heat away from the main pcb.  I drilled a couple of holes and mounted mine a couple of inches above the pcb.... Mine has a housing around it and heat rises, so it should be good.  I've gotta hunt up some wire tomorrow and finish the install.

Move the bed via either the on-board menu or within cura to a corner with the tape or whatever you use already on the bed.  Stick  a piece of typing paper under the nozzle.. you should feel a bit of tension as you move it in and out, but the paper should go under... use the included screw driver to adjust.  Now repeat for the other three corners of the bed.

Yeah, I just plan to do the cube.

So I downloaded Skynet 2.2 and am looking at the directions, Seems simple enough, but I do have a question. It sys you need to select the correct probe configuration before you compile. There are two choices I think that would apply to me - Stock A8 with front left tubular sensor or Stock A8 with official rear sensor. My machine is totally stock, so which applies to me? According to the comments in the code, it says "I recommend for the A8 that you use the front mounted sensor (8MM) because they give greater sensing distance). Or is this for a auto-level sensor and I don't need to uncomment anything here? Advice?

Post by: Howard_Casto on November 06, 2017, 02:35:21 pm
Full stop.  The latest version of Skynet is 2.3.2.  You don't really comment or uncomment anything.... you download the master zip file, go to the Skynet folder, go to the anet a8 folder and then select the appropriate configuration file to put in the main Skynet folder.  There's an illustrated readme if you scroll down the included link. 

https://github.com/thijsk/Skynet3d (https://github.com/thijsk/Skynet3d)

I believe cura isn't included in this zip, but I have the older version of the zip file if you need it.

I installed Skynet 3D last night. Compiled & flashed flawlessly. I want to finish cleaning up my wiring tonight and then I will be ready to print The Cube.

I did order some inexpensive but I highly rated filament to start testing out. The funny thing is the first set of things I plan to print out is upgrades for the printer.

Print out one thing at a time.  If a print screws up it's better to screw up one thing instead of 8 things.  Of course once you are more confident you might want to print batches of parts.... I'm still not that brave yet.

The edges are nice and crisp, as you can see. Iím curious about the layer fill. Also, on the Z sides, you can clearly see some gaps.

Now, I didnít change a thing in Cura, just loaded the cube from Thingiverse, hit print, and this was the result. Any tips?

 Btw, this was the THIRD try. Back to auto-leveling being a PITA, I thought I had it leveled once, but clearly it was too high, as nothing stuck to the bed. So I adjusted... and the nozzle ended up tearing up the tape. I have thick painters tape, so I tore up that yellow and put the blue down. I finally got the nozzle low enough, adjusted the Z stop switch, and then success. But my dick be paininí.

You said you didn't touch cura's settings at all.  I'm assuming you created a machine profile for the anet right?

I did a machine profile at the start.

The Anet troubleshooting guide says to up the fill layers. Itís not the test cube that comes with Skynet, itís one I got off Thingiverse.
Title: Re: So ... 3d Printers....
Post by: Howard_Casto on November 07, 2017, 10:04:39 pm
Is it a stl or something pre-sliced?  Something is certainly wrong because the test cube I printed didn't have that kind of separation.  I used the included cube though.  Having the bed off level would only effect the bottom of the print unless it's REALLY off level.  Upping the fill layer probably won't help because we aren't seeing separation on the z axis but rather on every axis.  Actually those look like diagonal lines, which shouldn't be possible unless there are diagonal lines on the 3d model.  What's the elevation like in AZ?  It effects baking so I suppose it could effect 3d printing.  I'm honestly kind of dumbfounded at the results you are getting.

I thought so.  ;)

That looks a lot better.  With some more tweaking you can get an even straighter cube, but you are in the ballpark now, so no need to swim to China and complain.  :)

What temp are you setting the hotbed to?  I realized after a while that heat isn't really necessary for pla.  You can really print with it off, but I found 40c is just warm enough to help you pry the print off without melting the bottom of the print.  It really depends on what you are printing though. Playing around with settings can drive you mad.  I would suggest you start printing utilitarian objects right now so you can tweak as you go and not get frustrated about "ruined" prints. 

Anyway, welcome to the club man..... you'll be printing cool swag in no time.

Cube is look in good dude!  :applaud: :applaud:
It takes a minute to learn what to tweak and when to tweak it. Once you get the bed level you shouldn't have to mess with it too much after.

As Howard mentioned printing multiple parts simultaneously can cause issues. If one messes up it usually messes everything up. Printing 2 things at a time If the parts are not to complicated should be fine.

I am not sure if CURA has an option to print each part individually or not. I ended up buying Simplfy3d which allows you to do individual parts, with their own settings/speed/infill.

Do yourself a favor and buy a PEI sheet now.  This is the one I bought:

https://www.amazon.com/dp/B074XK8BWY (https://www.amazon.com/dp/B074XK8BWY)

No more messing with tape.  When the print cools it pops right off.  It also gives your print a smooth as glass bottom. 

Sheet starts becoming less "sticky"?  All you have to do is wipe it down with rubbing alcohol. 

I hold mine to the hot bed with tiny binder clips, works great.

Ok, so Iíve got the hang of bed leveling and all that other stuff. Here is a picture of a bracket I printed to attach the MOSFET to the main board.

(https://uploads.tapatalk-cdn.com/20171110/545107e453566f0d873fd1671d9dd18c.jpg)

Iím generally happy, although you can see that the post holes are pretty rough. I can clean up the internal holes with a drill, but Iíd like the outer diameter to be a bit more round. So now I guess itís time to tweak the other settings.

Any suggestions for optimizing my prints? Any magic numbers or checkboxes I should pay attention to?
Title: Re: So ... 3d Printers....
Post by: 05SRT4 on November 10, 2017, 12:52:12 pm
Based on the bracket you printed Id say you may be over extruding (blobs everywhere, holes are smaller then expected)

To fix the over extruding I think in Cura you would change the FLOW settings. By default its at 100, maybe bump it down a little.

A good way to test is print a 10x10x5 test cube. Then measure it with a caliper, if it comes out larger lower the flow rate. Bump it down to like 96 and print, measure again.

The stringing can be caused by the temp being to high or the retraction settings need to be adjusted.

Lines on the top layer (Dragging) is usually an indication that the nozzle is too low, try raising just a tad.

Here a good Troubleshooting Guide (https://www.simplify3d.com/support/print-quality-troubleshooting/) that I always turn to if I need help.

And last SPEED. You will eventually find your printers sweet spot, both of mine are usually 50-60 mm/s. For smaller prints I will go lower

I have a different printer, but will mention a few things.

I print PLA at 190-195, but different brands of filament have required different temperatures.
Hard to tell from the pic, but the first layer looks blobb-ier.  There are separate settings for the first layer in Cura.  You might double check those.

One of the little things that improved my prints was making sure the wall thickness was set to a multiple of the nozzle diameter.

190 for me.  The key to good prints when you have to bridge gaps is to have the plastic cool and harden as quickly as possible so it doesn't sag.  If the plastic is melting fully then it's hot enough.

Yeah, those came out fine, and are very functional.

I have a question about overhangs. I printed a frame for the LCD monitor. In this design, there are two areas with long spans in them. As you can see, the tops look fine:

(https://uploads.tapatalk-cdn.com/20171111/729096ccddbfdc883c3789138381abcb.jpg)

But on the bottom, the sides where there is no support under the spans, itís a stringy mess:

(https://uploads.tapatalk-cdn.com/20171111/b6112634ecf75e866a6e95107a4a3276.jpg)

(https://uploads.tapatalk-cdn.com/20171111/078299d1827f525f9ef85c1627b916b6.jpg)

I figure thatís because there is no support under the overhang, plus the length of the run. Is it normal? Should I print it with supports underneath? Or is there a different setting I should look at? Thanks so far!
Title: Re: So ... 3d Printers....
Post by: Slippyblade on November 11, 2017, 11:49:25 am
If you tell it to print with supports, it just makes these really flimsy posts underneath the overhangs.  They really help and then when done, they just snap off.

Thereís a section thatís bridges by a little piece thatís only maybe 1 cm between the back plate and the nozzle, and that piece was wrecked during printing. So much so that I had to stop the print because it ruined the nozzle part. So Iím reprinting it, but I laid the piece on its back so the bridge is built horizontally, and I increased the print temperature to 200. I also increase the print speed to 35 just to see what happens. Itís been fun tweaking and tinkering with Settings, I feel like Iím 90% there, I just got to get it dialed in.

Oh, and thanks for all your help. It just saddens me this is the only thread on the site worth a damn anymore.

If you tell it to print with supports, it just makes these really flimsy posts underneath the overhangs.  They really help and then when done, they just snap off.

Yeah, Iíll probably have to do that. I wasnít aware of the long overhang when I loaded the model, it was something I got off Thingiverse, and actually I cleaned it up with a Dremel so it doesnít look bad at all. Itís just a piece itís going on the back of the printer to help enclose the LCD, so Iím not worried about reprinting it, but I will keep that in mind for future prints. Thanks!

What you'll find going forward is the key to doing good prints is learning how to best use supports and orient the parts.  Anything with excessive overhangs will have a "bad side" even with supports (although it'll look significantly better with supports,  I use the "touching buildplate" option.).  You just want to orient parts so that unimportant, smaller sides get the overhang and sometimes add a sacrificial layer to the print that you know will get ruined and cut it off.

So if you were printing this, would you use supports?

With no supports that still came out surprisingly well, for the price you guys paid the print quality has been amazing.

For the support question. Yes I would print that with supports.

Question for the CURA users, does it it allow you to place supports where ever? or does it auto generate based on your settings?

(https://i.imgur.com/PD3pdlN.png)

Yots, thats what the print would look like if I was going to print, dark spots are the supports. If the underside isn't going to be seen you can usually still with a less dense support infill.
Title: Re: So ... 3d Printers....
Post by: Howard_Casto on November 11, 2017, 07:03:01 pm
Cura has a few options via plugin I think, but thus far the auto generation has been pretty good and I haven't tried anything else.  That's about what the auto-generated supports would look like on a part oriented that way.  If that is the front then that is the way to do it.

Post by: yotsuya on November 11, 2017, 07:18:21 pm
Yeah, Howard is right. I wasnít using the support check box, but I will do that when I reprint the piece.

Reprint, you say? Why yes, it doesnít fit. I did some investigating and realized that my Y-axis belts are too loose. I tried printing something round and it was coming up oval, so I tightened the belt and it made a huge difference.

I haven't had it loosen yet, so if you have it secure it should stay.

Right now I'm investigating the one flaw in the printer's design.... changing the filament.  It's a huge pain.  I've seen a few on thingiverse that allow the fan assembly to open like a door... I'm thinking a simple cone to attach to the throat of the top of the hot end assembly might work better.

I guess I should check back on this thread more often.  Glad to hear that folks here are enjoying 3D printing.  I haven't been doing as much as I'd like to but that should change with winter coming.  I do remember the A8 filament loading problems.  I was able to get good at doing it with practice and a few tricks.  1. cut the filament end at a sharp angle to get a nice point to work with.  2. straighten out the filament from it's natural curve from being on the spool so it will actually go where you are aiming it.  3. practice a few times with the fan off so you have an idea where that hole is that you are aiming for.  I was able to get good enough to reliably hit that hole on the first or second try.  Even so, some people never get the hang of it.  I did end up switching to an E3D hotend and Bowden setup - mainly to use higher temp materials but a side affect is no more loading issues.

Speaking of pegboard, lots of benefits to 3d printing your pegboard stuff for the shop/garage.

I found the parametric pegboard tool to be very very helpful, especially when dealing with my special sized stuff.

And for pegboard, if you have those hooks that just slip down, these clips are a MUST. I will not go back to hanging hooks without em.

I also use epoxy all the time, so I made disposable mini pallet knives for small epoxy jobs, since they only give you one mini popsicle stick with each package of epoxy. They work great and hang on pegboard. I attached the STL.

The only time ive had to sand something is because I didn't calibrate / compensate for something and two pieces dont fit. Or if I plan on painting the model I will sand a little.

Yeah, totally depends. 90% of the time, no. I was interested in Acetone Vapor finishing when I first got into 3d printing, but nothing I build needs that much attention.

I do occasionally sand down and fill the z banding, spray paint, brush on acetone, reshape with a plastic welding iron, etc. to a print if there is a need.

That's something we both need to research.  When I first setup my printer the docs said to stick with that version, but that was over a year ago.  It's a stand-alone app, so I suppose multiple versions could run on the same machine.  Worth a shot.

Finally dove into the multi color on single extruder printing. Doing it in simplfy3d was super easy. In the latest 4.0 update there is a process spliter that lets you set specific settings for individual layers. I just did 2 processes, after the first job the printer head moved to the side allowing me to swap out the filament, then I started the next process and it continued where it left of, super cool.

When I swamped out the filament it re-homed X and Y then went back to printing so moving the head wasn't an issue. Usually the motors will still be locked so I dont think it would move to much. But you guys did mention that your printers are a pain to change filament.

Here's a tip that I forgot to share.  If you are printing something you want to look nice and it's flat, print it face side down.  If you heat up the bed it will melt and smooth things out a bit.

Alright, last one I promise. Im just super chuffed I was able to figure out the multi color stuff. After Howard made the comment about the bottom top layer I went through and leveled my bed again which helped with the top layer. No more random lines.

So the interesting thing about this one is that there were 4 G codes just for the middle section. (Blue base, Red Belt, White Stars, and Gold logo) I actually printed the base, belt, and stars first and knowing that my nozzle wasn't going to be near the bottom I printed the logo after everything was done. All I really had to do is take out the Home Z code on all the processes.

So I printed a case for the LCD on the A8. It was actually my second print of it since my belts were loose and the first version was out of whack. The second version was perfect, but the back acrylic piece was too big! Apparently Anet makes design changes willy nilly and ships whatever.

Undaunted, I imported the case file into Tinkercad and used it to design a brand new back piece that snaps into place (so its multilayered). I also incorporated a space for a 40mm fan if I decide to add it. Took me about 20 minutes total to knock out the design.

I loaded it into Cura, and ran the print. The first run started to look poor, so I canceled the print and slowed the print speed down to 30 (from 40). I also turned the heater bed on.

What a difference! 9 hours later, I had a beautiful, professional looking part that fit perfectly.

That is one of the problems with 3D printers. They are great for many jobs, but they are super slow, at least the affordable ones are. A CO2 laser could produce that part in a few minutes. It would also be smooth and look like a finished production part. On the other hand, If you can only have one fabrication tool the 3D printer might be the most versatile.

Yots, you were producing usable stuff right out of the gate. It seems that the affordable 3D printers have graduated from the "print useless trinkets" phase.
I am going to have to pick up a 3D printer one of these days. There are many times I need a part that my laser is not ideally suited to.

Kudos to the work so far, and to the help you have received from the community.

That is one of the problems with 3D printers. They are great for many jobs, but they are super slow, at least the affordable ones are. A CO2 laser could produce that part in a few minutes. It would also be smooth and look like a finished production part. On the other hand, If you can only have one fabrication tool the 3D printer might be the most versatile.

Yots, you were producing usable stuff right out of the gate. It seems that the affordable 3D printers have graduated from the "print useless trinkets" phase.
I am going to have to pick up a 3D printer one of these days. There are many times I need a part that my laser is not ideally suited to.

Kudos to the work so far, and to the help you have received from the community.

Yeah, I had no desire to get one until Vigo introduced me to a really cool project that requires one. My friend Arcadenut printed me parts, but he uses his to make money and I didnít feel right asking him to print me additional parts (though he would have done so without hesitation).

The guys here made it super easy to get mine up and running. Thatís why I still come around even though Iíve outgrown MAME as a collector. Well, for that and the fishies.

So I printed a case for the LCD on the A8. It was actually my second print of it since my belts were loose and the first version was out of whack. The second version was perfect, but the back acrylic piece was too big! Apparently Anet makes design changes willy nilly and ships whatever.

Undaunted, I imported the case file into Tinkercad and used it to design a brand new back piece that snaps into place (so its multilayered). I also incorporated a space for a 40mm fan if I decide to add it. Took me about 20 minutes total to knock out the design.

When I want to test fit before doing the entire print, I'll just print out the first couple layers or however much is needed to check clearances.
If the part that needs test fit isn't on the bottom, just block off the rest of the design with a giant "box of empty space" in tinkercad.
The test parts are usually only 10 minute print jobs.

I bought some gauge blocks and got all psyched up to calibrate my printer, but it ended up being good out of the box.
I still have to play the high/low game with super precise parts, but I guess that's just the nature of the beast.

Buy a set of digital calipers if you don't already have them.  They make designing useful parts in tinkercad much quicker.

This has easily become the one tool I use 10x more after 3d printing. I've also grown much more comfortable with MM measurements.

No, I get it. I was leery at first, but after using it for a while, I have not noticed any thermal issues. Also, my main board is a revised version of the original boards. They use better connectors. I also made sure to use crimp terminals for all power hook ups instead of just straight bare wire. Between the fans and the MOSFET, I think Iím good. But trust me, I did my research.

I donít know much about other printers, but I will say that I am deliberately printing at a very slow speed because I prefer quality over speed. Once Iím done printing functional upgrades for the printer, Iíll experiment with speed.

Thatís a good point, LC, but for me, I want to make functional objects more than anything. The look of the surface isnít as much of an issue as the accuracy and durability of the object. And for that, itís great.

By settings a smaller layer height you can rid of most lines you see. But you are tacking on hours more to the build time. If your printer can handle 50-100 micron layer height (.05mm - .10mm) then you will see some really nice and smooth surfaces.

Yes you can vapor smooth most filaments, or you can sand a little and hit it with some primer. Most functioning parts ive made I haven't had any reason to paint though.

You shouldn't look at getting a 3d printer to make post production quality parts. Look at it more of a way to fill that creative void that us do it yourself hobbyist have. And at the price that these guys are paying! Now is the PRIME-time to get one :)

I have an odd question.  After printing does everyone find themselves just accepting the final product of the printer or do you spend time on your creations honing what you created?  ie sanding, etc...

Dude, it is all about real, out-of-the-home engineering. It opens a whole new world, and a real builder like you will dig it.

Very simple example I have from yesterday. I have a new video camera for work, and the microphone is too narrow for the shotgun mic arm. Without needing to search online for a conversion part, or going to my garage to see what I can cobble together, or running a wad a duct tape around my microphone I was able to solve this little problem. I just spend all of 5 minutes designing a part, threw it on the printer and an hour later I have a fairly professional looking solution. I can use this microphone at work without looking like an the idiot on the shoestring budget that I am on.

Now imagine having that ability for every aspect of something you are building, where you need a very specific bracket, clip, spacer, stand, enclosure, fitting, wedge, etc.... You can suddenly throw this together in no time and the bigger creation you are building looks much more professional because of it.

Went to print something after the spools have been in the open air for a few months.   First few feet of PLA was brittle AF and could not be fed into the printer without breaking.

TIL spools fit in foodsaver rolls. It is a tight fit and the bag needs to stretch a little.  Shame I didn't have a silica packet to toss in there.
(as an aside, I don't recommend the countertop food saver unless you have lots of unused counter.  The small cheaper ones function the same and can be tossed in a drawer.)

Its not terrible, It was much worse when I had the extruder too hot. I do put it in my basement, so I just shut the door while printing, its no bother. Smell doesn't linger or spread.

In case you didn't know. You can change the skirt to a brim. This makes the outer purge ring attach to the actual print. This helps will really small parts with little surface area to start with.

Okay, somebody please put together the no ---steaming pile of meadow muffin--- this is what I need shopping list so I can get started on this boondoggle. I want the cheap kit but with all the extra components and upgrades that everyone eventually realized they needed.

Please please pretty please and thank you.

No way, ---smurfette---. You need to pay your dues! Get the kit and suffer like the rest of us.

Get a PEI sheet. Thank me later.Also find a local friend who can print you all the upgrade pieces you need while you wait for it to get here from China.

If youíre going to get the A8 (and I would, for the price), start by reading this thread in its entirety, then go read this page here:

https://pevly.com/anet-a8-upgrades/

I used it to get the upgrade parts that Arcadenut graciously printed out for me. I had them on hand when I did the build. 

Sign up for an account at Thingiverse.com and Tinkercad.com to get started.

I bought a spool of this so that I could get started with long print runs. Itís been great to use for a learning experience.

https://www.amazon.com/gp/aw/d/B0722YQTPY/ref=mp_s_a_1_17?ie=UTF8&qid=1511193909&sr=8-17-spons&pi=AC_SX236_SY340_QL65&keywords=filament+1.75&psc=1

Get this MOSFET to take the load off your main board PCB and run power directly to the heaterbed:

https://www.amazon.com/gp/aw/d/B06XY5HBFX/ref=mp_s_a_1_7?ie=UTF8&qid=1511194053&sr=8-7&pi=AC_SX236_SY340_QL65&keywords=mosfet&dpPl=1&dpID=51FrR--Y6qL&ref=plSrch

Buy a PEI sheet, binder clips, and some 608 bearings. Print out the TUSH spool reel that HaRuMaN linked to.

Finally, go here and just read everything:

https://3dprint.wiki/reprap/anet/a8

This was all a part of my journey to get to this point!

Ive decided ime going to take the plunge in the new year and buy one to play with!

Think ime going to get a Creality CR10 mini.
They seem pretty good for the money.

Just bought the CR-10 (normal) for 330$ will let you know how it is.

Shes up and running, ran into one issue. After getting everything setup I turned it on and nothing would power on. I opened the control box and saw that I was getting 120v to the PSU and 12DC out. After tightening the power wires to the motherboard everything turned on. This will be my first printer with a bowden style extruder.

This was covered a little ways back

http://forum.arcadecontrols.com/index.php/topic,152421.msg1633821.html#msg1633821 (http://forum.arcadecontrols.com/index.php/topic,152421.msg1633821.html#msg1633821)

Basically its a way to watch and manage your 3d printer. I like it because I have all my printers downstairs and my main PC that I use to design, slice (3d printing stuff) is upstairs. I design and slice a model on my PC, then open Octoprint (in a browser) send the gcode and start the print. You can then watch it from the PC upstairs , or on a mobile device.
And when I need to manage Octoprint while downstairs next to the printers I can just load the site on my phone or tablet.

Just watched a yt video looks interesting.
May look into that at some point but as this will be my first printer think I will start off small.

What is everyone using on their beds?

Seems a mine field of different ideas out there!
Title: Re: So ... 3d Printers....
Post by: 05SRT4 on November 28, 2017, 06:49:16 am
What is everyone using on their beds?

Blue Painters tape is the most common, cheap but is annoying to swap out every other print.

PEI sheets is the next most common, usually one sheet will last a really long time and long as your not jamming the nozzle into it.
and once it starts to lose its jazz you can wipe it with a little isopropyl alcohol and it should perform like new.
Title: Re: So ... 3d Printers....
Post by: Titchgamer on November 28, 2017, 08:28:17 am
I looked at the PEI sheets before and I liked the idea of them, But they seem to be a real PITA to find over here.
Ile have a look to see if I can get a sheet the right size and clip it to the bed.
Title: Re: So ... 3d Printers....

Why did you get the Mini? seems like the price is only 20-30 difference.
Title: Re: So ... 3d Printers....
Post by: Titchgamer on November 28, 2017, 10:54:17 am
A few reasons really.

1) Its slightly smaller which is good for where I want to put it (my house is pretty small) and I am unlikely to need that extra 80mm depth for what I intend in printing.
2) From what I gather the mini is better built than the standard CR10, No printed parts all metal/cast/moulded. But also keeps all the good stuff.
3) its £40 cheaper lol

Well I will prob spend more on it in the long term as is the way.

But as I stated above its a better build quality and smaller footprint to fit on my table so ime willing to sacrifice the 80mm for that.

The standard cr10 has glowing reviews so I have high expectations :)

I leveled it with a bare bed, then put down painter's tape, so I think that screwed it up.  It seems like the nozzle was actually slightly dragging on the first layer.  Pics are the bottom layer and then the top layer.

Make sure you guys do a legit extruder calibrate before messing with the flow rate. Its simple just measure and mark 100 mm of filament from the top of your extruder and have the system feed 100 mm. See if the line levels out or if it come up short or feeds to much. Then adjust the steps in marlin or what ever firmware your using.

My second printer was coming up way blobby no matter how low I had the flow rate. Found out I was extruding 150  for every 100.

There's a slightly different extruder calibration procedure here (http://zennmaster.com/makingstuff/reprap-101-calibrating-your-extruder-part-1-e-steps) that works for over-feed and under-feed.
- Measure and mark at 120mm
- Feed 100mm
- Measure where the mark falls
-- If it is at 20mm, the setting is correct
-- If not, use the formula    (Expected feed length / actual feed length) * current steps setting = new steps setting

For example, if you expected to feed 100mm, but only fed 96mm (120mm start position - 24mm end position) with a current steps setting of 150, you would need to adjust the steps setting to 156.25.

(100 / 96) * 150 = 156.25

Slippy, if your using Cura, make sure the filament size is correctly set to 1.75. The default is larger.

Hereís why I love 3D Printing. Every year, we have a Christmas party with a killer white elephant. Every year we make the little slips with numbers and such.

I had a brainstorm the other day on a way to make the process easier and have some fun. I jumped in to Tinkercad, and voŪla!

(https://uploads.tapatalk-cdn.com/20171202/88058803e3006ea00aba8ec952235ea1.jpg)

A nice, cute, fun and permanent way to do our white elephant. Weíll use these at Our party, and then two weeks later at our family Christmas party. Then we have them already for next year! Thanks, additive manufacturing!

If I was using this purely for making money I would take the time to figure that out. I know for a fact that the filament for each badge is only 12 cents, electricity probably .01 cents if that, printer 330$

Fun fact.  That monkey with a razor is from a little known 80's horror film called creepers.  It's well worth a watch.

I printed out one of the carts for the snes classic last night, only I hollowed the model out first.  I think when I moved my printer the other day I threw the calibration out of wack because it got some crazy bad z-banding and one side lifted... something I haven't had happen on this printer yet.  I'm going with pbj's idea... make it hollow and when/if I decide to do a usb expansion, I can put the stick in the cart.

Well I tin foiled the underside and it made quite a difference!
Still not perfect but should be useable.

I attempted to print the decapacat, It started off good but it started to peel after the first layer or 2 and ended up catching the nozzle.

I am hoping thats because my bed is dirty. My Isopropanol has not yet arrived so the bed has not been cleaned properly yet.

So I need to ask you guys using PEI.

What sort of settings and tricks are you using etc?

Ime really struggling to get this printing properly.

So currently I have it set at 0.2 with a speed of 40mm.
My bed temp is set to 65 (actually about 50-55) and nozzle temp 196.

It always seems to start peeling at the same place (back of the cat) and catch on the nozzle before being pulled off the bed.

Ive re-levelled the bed several times and cleaned with isopropanol 90%.

Title: Re: So ... 3d Printers....
Post by: 05SRT4 on December 05, 2017, 07:26:29 am
Pull the filament out, start the print and pause it mid first layer. Slide a piece of paper between the bed and nozzle and check to see if its touching the tip or not, you should have a slight drag, if not the tip is to high. If its tight then the filament may be scrapping itself. Also, although I print around 40-60 My first layer is usually 30-40% of that. If using Cura there should be a first layer settings.

If your using the small roll of filament that came with the printer try 210C for the temp instead.

Using a bowden extruder I learned that the retract settings a way different from direct drives. Normally I would set my retract to .5 - 2 max. The bowden seems to work best at 5-6mm. I think I finally found a sweet spot on the CR-10, was able to print 4 badges at the same time, all came out level.

One last thing, Im not sure if Cura lets you move the model ,maybe try moving it to a corner or mid front to see if it prints better there. I have a dead zone I try to stay away from on my other printer.

When I do the bed levelling with the paper I also do the centre spot.

It drags but not quite as much as the corners but as mentioned previously my beds dipped in the centre.

I was using the PLA that came with it but ime just about to try again with a new roll ive got.
My retraction is set at 5mm 60mm/s speed.

So I was able to print a cube with your settings.

But I would change a couple settings.

First (Not sure if the Mini has the same) I hate the "Wipe" gcode they put in, I think it just causes stringing all over the platform. My starting Gcode is only G28.

I just use the skirt to purge everything.

I would keep the Thickness at .8 (2 shells is perfect for most prints)

Top and bottom layers I usually only do 2-3, again Cura basis it off your layer height so .4 to .6 is a good start. If you notice the top layers are bumpy from the infill then you can up that.

Temps: try 200-205
Pattern: Ive always picked lines over the concentric.




Title: Re: So ... 3d Printers....
Post by: 05SRT4 on December 05, 2017, 01:01:14 pm
Also ditch the cat and make a 20 x 20 x 20 cube in tinkercad and work on that. If its the Stl or gcode that came with the printer it may be bad, I couldn't even get mine to load and the forums are saying they never got it to print. There is a new one on Thingiverse if you really want it.
Title: Re: So ... 3d Printers....
Post by: Titchgamer on December 05, 2017, 01:41:27 pm
Ile give them a shot tomorrow mate cheers. No natural light now.

Ive been googleing the curling fillament and the general idea seems to be it may be a partially clogged nozzle.

Suggestion seems to be heat the nozzle up to around 220 and push a little through.
Then reduce to 90 and yank out the filament once cooled to pull any crap out with the filament.

Few things for me to try tomorrow, I may get this thing going eventually....

What do you mean about the wipe and g28 start code btw?

Total novice at this stuff :)
Title: Re: So ... 3d Printers....
Post by: 05SRT4 on December 05, 2017, 02:55:31 pm
There is a Gcode that happens before and after every print, the Cura Cr-10 profile has a code that makes the hot end  home, then wipes a line of filament like a purge then starts. On most of my printers I just have G28 to home everything and thats it. Thats just my preference though.
Title: Re: So ... 3d Printers....
Post by: Titchgamer on December 05, 2017, 04:09:06 pm
Ahh right so get rid of the line under G28 then?

From recent research at least, there used to be a big diff between stock Marlin and Skynet, but recently Marlin adopted many of Skynet's features.  Now if we could just get a pause feature and a resume feature both would be perfect. 

I'm about to start printing the top of my Nintendo sign for the world of Nintendo cabinet.  For those of you following along at home, it was this non-stop print job that burnt out my previous power supply, so wish me luck.

Same with mine, but I am using a repetier host based printer. Even then, I prefer to add a pause line to the gcode when pausing to change filament colors or insert something inside the print. That way I can determine the exact point in which the print stops.

Really?  Do you have to use the printer's menu or can you do it remotely?  I just use pause lines atm, but it'd be nice to pause a long print before going to bed, ect.

Btw, on the Anet FB Group, most people are saying to switch to Marlin. They said even the Skynet developer recommends this.

Post by: Slippyblade on December 08, 2017, 10:51:16 am
From what I've been able to piece together, Skynet was a fork of Marlin back in the day, but they recently re-absorbed into the main Marlin codebase.

(https://uploads.tapatalk-cdn.com/20171209/24c6352880fbf573ce9898f3ffbac7cb.jpg)

The heat bed is Aly but is slightly bowed also.
But its only thin so no real surprise there.

I have emailed a local glazer with my requirements see what they suggest.

I agree, reading online the ones that have said something ended up getting replacements.

I ended up swapping the glass plate with another one I had. The one Creality sent had to many deviations. The Heated bed actually wasn't that bad. Running the Dial thingy I got from Harbor Freight and a custom gcode I made I was able to compare everything. The heated bed never went over 5 microns (.005) The Mic 6 Casting plate I got was the same, although there wasn't as much change throughout the entire plate. just a couple areas went near the .005 tolerance it stated.

Doing the test on the glass Creality sent the dial was all over the place. Some areas dipped in and out of the 10-15 microns, no consistency at all. This was tested on both sides. 10-15 microns doesn't seem like a lot but you could see it in the bottom and top layers.

Titch one thing you can do to try to help is change the first layer thickness maybe to 150-200% this will put down a fat layer that will help fill in those dips.
Title: Re: So ... 3d Printers....
Post by: Titchgamer on December 09, 2017, 06:02:05 pm
The bed itself is not that bad tbh and can be straightened out using the adjusters.
I suspect a good piece of glass would pull it straight also.
Like I said its only thin Aly.

But the glass is way to far out to do anything with so ile just buy a nice new flat piece somewhere local and roll with it.

Just gutted my £20 sheet of PEI is wasted :(

Post by: Howard_Casto on December 10, 2017, 12:49:52 pm
Yeah I got a chuckle out of that.... there aren't that many parts, and you are really supposed to peel those off (except for connecting points) after it is assembled so you don't scratch anything.  I mean the way the bolts and nuts attach via those cut slots is a pain in the butt, but once you get the hang of it, it isn't that bad.  Being honest it probably took a little longer than an hour and a half as the final assembly videos I watched were a little sketchy and I had to go back and re-watch them a couple of times, but certainly not for 12 hours.

Is that full size? I scaled mine down to 25% to test it first.

Out of interest is it the light or are his front teeth slightly moulded together?

print me some...
First test print started.

The notes on thingiverse say that the screw hole sizes aren't confirmed yet.

What size screw does it use for the crossbars (outer holes) and what size for the PCBs? (inner holes)

Looks like they are different sizes.  #8-32?  #6-32?


Scott
EDIT: Print completed. The holes are different sizes.

The crossbar holes are the right size for #6-32 screws.

The PCB holes appear to take something smaller than a #4 (0.112" diameter) sheet metal screw, maybe a #2 or #0 sheet metal screw.  :dunno

Turning the print 90 degrees on the long axis should result in a smoother ramp.

EDIT2:Turning the print increases the odds of the PCB screw holes splitting due to layer separation.

The inner holes are smaller.  A number #6 machine screw was ever so slightly too large. (One of my attempted kludge repairs)

Original part was a sheet metal screw.  Maybe their thread is a little smaller?

I can believe 6 and 8 are the right sizes.... will try to confirm tomorrow.

I can believe 6 and 8 are the right sizes.... will try to confirm tomorrow.
Machine screws and sheet metal screws have the same thread outer diameter for corresponding sizes, but the tpi (threads per inch) are different.

The threads on a #6-32 machine screw (32 tpi) are the same outer diameter as the threads on a #6-20 sheet metal screw. (20 tpi)

#2: 0.086"
#4: 0.112"
#6: 0.138"
#8: 0.164"
----------
Here are the rough measurements of the printed part:
2.835" long
0.795" wide
0.775" tall at the highest parts (inner screw towers)
0.200" outer diameter of inner screw tower  *** this looks too thin to handle a #4 or #6 screw hole ***
1.065" center-to-center on the inner screw holes
2.475" center-to-center on the outer screw holes

Snapped a few pics this morning.  Sorry, didn't have a metric ruler nearby.

The black screw is the one that holds the horseshoe PCBs to the inner posts on the plastic part.  It's too small for a 7/64" hole and too large for a 3/32" hole.  The larger bolt screws perfectly into a 1/8" hole, and slides through the larger holes on the end of the plastic part.  Note that it just passes through that hole, it doesn't actually screw into it.

The black screw is the one that holds the horseshoe PCBs to the inner posts on the plastic part.  It's too small for a 7/64" hole and too large for a 3/32" hole. 
Since it's between 0.093" and 0.109", it is probably a #3 x 5/16". (0.099" diameter threads)

If so, those two screw holes probably should be enlarged from about 0.055" and 0.070" to about 0.081" (#46 drill bit) or 0.078" (5/64" drill bit) to reduce the odds of splitting.

The larger bolt screws perfectly into a 1/8" hole, and slides through the larger holes on the end of the plastic part.  Note that it just passes through that hole, it doesn't actually screw into it.
From your pictures, it appears that the machine screw is #5-40 x 5/8". (0.125" diameter threads)

For these holes, a *very* slightly larger diameter hole will allow the screw to pass through easier or you can run a 1/8" drill bit through them.
--------------
Do you have calipers to verify the outer diameter thread sizes?


Scott
Title: Re: So ... 3d Printers....
Post by: pbj on February 15, 2018, 02:34:00 pm
Yes, I've got calipers laying around somewhere as part of that research lab tool looting I did 3 years ago.  I'll dig them out and measure anything you want, baby. 
Title: Re: So ... 3d Printers....
Post by: PL1 on February 15, 2018, 03:59:34 pm
If you could confirm these four measurements, that should be enough for Haruman's friend to make several helpful adjustments to the .STL file.

1.) 0.125" outer diameter threads on the #5-40 x 5/8" machine screw

2.) 0.099" outer diameter threads on the #3 x 5/16" screw

3.) 0.081" (?) screw body diameter (valley between the threads) on the #3 x 5/16" screw
- The pilot hole should be this size or slightly larger to reduce the odds of splitting the cylinder during tightening.

4.) 0.200" outer diameter for the inner screw towers
- Can those cylinders be a larger diameter to reduce the odds of splitting/stripping?
- If so, how much larger would you recommend?

Top scale is cm broken down to mm. Bottom scale is inches broken down to tenths of an inch. So for example, the screw in the last pic is 2.1 cm long. (which is the wrong way to measure the length of a fastener, correct length of that screw is 3/4")

Widget, depends on how hackerish you wanna get.  The Anet-A8 is a kit.  That requires a lot of assembly/calibration/babysitting, but is very inexpensive.  A lot of us have that one.  Then there's the Creality CR-10.  More expensive, but it's a lot more turn-key.  Comes assembled and ready to print I believe.

I don't want to scare people away from the anet though.....  if you are comfortable with assembling furniture the a8 isn't all that different..... there are just a lot more parts.  It's the last "tool" I've bought in a long time that I use constantly.  It's good for figures and stuff as well, but I haven't had much time to play with that aspect of it yet.

Not-so-good news: No luck getting readings from the photos to match up with thread-size charts.   :banghead:

Good news: Found a diagram for the Williams D-7931-5S drop target assembly on Marco Specialties (http://www.marcospecialties.com/pinball-parts/D-7931-5S) showing that the machine screw is #6 x 3/4".   ;D

Mixed news: The PCB screws are labeled as P/N 20-8815 in the diagram below and P/N 20A-8815 in another version of the diagram.

The horseshoe screws are sheet metal #4 x 1/4".

Question for PBJ: Are the PCB screw threads the same diameter and pitch as the horseshoe screw threads?

(http://www.marcospecialties.com//images/products/D-7931-5S/additional1/large.jpg)

Anyone know where this diagram came from?

Haven't found any manuals with a similar parts breakdown.


Found it.   ;D

Planetary Pinball (http://www.planetarypinball.com/mm5/merchant.mvc?Screen=BOOK) has online copies of Bally and Williams parts catalogs, including Williams 1980 (http://www.planetarypinball.com/reference/partsmanuals/WMS_Parts_1980/index.html).

Drop target assemblies are on pages 113-118 -- they all use the 03-7479 guide.

The D-8362 assembly diagram on page 116 shows PCB screws that are the same P/N as the horseshoe screws. (4104-1001-06)

So after making the whole VR PVC cockpit thing I soon realized how annoying it was to move around in my small VR room. So instead I wanted to try to incorporate HOTAS mounts onto my computer chair I already had. I have the idea, I am in the middle of printing it all up. Finished one piece last night 14 hours, 3 shells, 2.0 layer height.

I've had good luck with PLA.  I do 3 perimeters and a 50% quad subdivision infill when I need strong parts.  So far the only time I've needed to worry about PLA is if the part might get exposed to heat above 100ish degrees.
Title: Re: So ... 3d Printers....
Post by: Howard_Casto on March 07, 2018, 04:00:19 pm
The first thing I did with my test pla cube was stand on it.  I then tried to smash it with a hammer.  It's still fine.  Pla is susceptible to heat as mentioned, but other than that it's very strong, probably just as strong as abs.

As 3D printers get cheaper and are more commonplace, people have a tendency to let their guard down. 3D printers need to be inspected regularly, and leaving them unattended while they work a job poses a certain level of risk.

I am not denigrating cheap 3D printers. They seem really useful. They just need to be treated with a higher level of caution than many other tools. Especially the really cheap ones.

When I run my lasers for work, I stay in the room with them. I moved a computer into that room and routed a network connection so I can work and man the fire extinguisher if necessary. :cheers:

So firstly I designed my first 3D model, a charging dock for a PSP and printed that:

(https://uploads.tapatalk-cdn.com/20180330/90938335129ea2a0372240c50611b209.jpg)

I also printed this as a surprise for the Ms, is a wedding cake topper :p

(https://uploads.tapatalk-cdn.com/20180330/7433cb8252ffba04193242599a6ad137.jpg)

Also I have just finished printing a fully articulated metal gear rex.
Ile get some pics up once its painted but that may be a while yet as theres lots of pieces!!

When I was printing Rex one of my box fans started getting noisy so I have ordered some new silent fans for that.
Fitted one but gotta wait a week for the other :(

I also fitted dampers to the X & Y steppers during the down time to help quieten it a bit and a new metal extruder.

Nice idea!  You actually beat me to it on the joystick guide.  One suggestion..... the peg in the center... you might want to put a hole just big enough for a pencil/pen to fit.  That way if you are also drilling the hole for the joystick you'll have a mark for the pilot bit on your hole saw.

Just remembered btw Howard,

I noticed my filament breaks if I have not used the printer for a week or 2, usually just infront of the extruder gear.
I guess the gear puts pressure on it over time and it breaks.

What I do to fix it is pull the Bowden tube out of the coupling that comes out of the extruder, pull the remnants of the fillament through them heat up the hot end to 200 and give it a sharp tug back down the bowden tube.

Then just feed new back in as normal.

If/when you update this drill guide with a center hole as suggested above, you may also want to add a triangular notch on the center of each side.

Align the notches to horizontal and vertical lines drawn on the panel and your sticks are both perfectly positioned and squarely aligned.   :cheers:

Yeah there's gotta be an easier way though.  I've already added some g-code in my shutdown routine to push the bed out to present the finished part.... maybe if I add some code to back the filament up a bit it'll relieve some of the strain.

Yeah I need to invest in better bearings.  I've been looking into tool changes actually.... there have been a few a8 mods that allow for plotting, vinyl cutting and small scale cnc.  (Think pcb mill.)  I've just yet to see a carriage that looked sturdy enough for precision printing.  I think it is doable though.... I actually made a simple plotter attachment and it worked fine.

Not something ime ever likely to consider seriously though tbh.

Anything that small ide get the guys at work to do for me on a night shift lol

But yeah totally do the fan/dampener mods to your printer if you can.

So I found something useful:

https://www.thingiverse.com/thing:2070636 (https://www.thingiverse.com/thing:2070636)

Ignore the part, that may or may not apply to you, but check out the program in the description.  That's what I've been looking for, an automated app to alter the gcode for x-axis plotting.  This would be useful for plotters, vinyl cutters and possibly even pcb milling.  See you need the code altered to basically keep the tool from dragging while moving about... it needs to retract for non 3d printing applications.

So has anyone converted the anet a8 to use a Bowden style extruder?  I've been thinking about it since, in theory getting the weight off the carriage would eliminate wobble and increase the overall speed.  The only thing holding me back is the fact that I would have to print a new carriage.  I dunno, a pla carriage just doesn't seem like it would be sturdy. 

But I mean the conversion itself is stupidly cheap.... you can get a j-head hotend complete with Bowden conversion parts for around 10 bucks on amazon.  I just wonder if I'm wasting my time.

I would like the option to do ninjaflex and stuff but honestly I can't think of a use for it.  I'm trying to design a changeable head system as I'd really like to do a drag knife for vinyl and a laser for engraving and this just seemed like it would make the whole thing easier, but if my prints are going to suffer for it no dice.  I'm open to suggestions.

PBJ just confirmed that several prints of v0.03 of the Williams Drop Target Guide (P/N 03-7479 or 3B-7479) are installed and working in his Alien Poker.
- v 0.03 - Narrowed columns, adjusted ramp, adjusted position of wall near ramp, enlarged bottom screw hole 10 Apr 18
- v 0.02 - Changed default screw hole sizes 27 Mar 2018
- v 0.01 - First draft 27 Mar 2018

This SCAD file recreates and remixes the model posted here (https://www.thingiverse.com/thing:2792174) on Thingiverse by Haruman's friend.
 - Corrections to that part are based on measurements of original parts
 - PCB columns changed to ovals for greater strength
 - Inspected by PBJ for accuracy and suitability

This part is used in Williams System 3-6 tables.

Planetary Pinball has online copies of Bally and Williams parts catalogs here (http://www.planetarypinball.com/mm5/merchant.mvc?Screen=BOOK).

The Williams 1980 catalog here (http://www.planetarypinball.com/reference/partsmanuals/WMS_Parts_1980/index.html) contains related parts diagrams.

Drop target assemblies are on pages 113-118 -- they all use the 03-7479 guide.

The D-8362 assembly diagram on page 116 shows PCB screws that are the same P/N as the horseshoe screws. (4104-1001-06)

Drop target assemblies that use the 03-7479 guide:
     D-7931-#s  -  # = number of targets (between 1 and 5)
     D-8362     -  5 targets
     D-8442     -  3 targets
     D-9355     -  3 targets

Screw sizes:
 - #6-32 x 3/4" machine screw
 - #4 sheet metal screw

The attached .ZIP file contains the .SCAD file (you can modify the part using OpenSCAD (http://www.openscad.org/)) and .STL file.

Print with supports and your choice of filament -- the ones I sent to PBJ are Hatchbox PLA.

So did you screw right into the holes or did you have to tap them first?  I'm only asking because I've had mixed success in regards to screwing into pla without it splitting.... seems to depend upon the model greatly.

Screwed right in.

This part is unobtainium, other collectors I know are happy to see this come to fruition.  Found out one of my mosfets is blown on my $300 repro MPU.  But thatís another thread.

No need to drill/tap this model because the screw hole sizes are exactly the right size . . . at least for my printer and slicer settings.   ;)

- The machine screw holes (outer columns) just barely brush against the threads.

- The PCB screw holes (inner columns, top) even survived a test using a #6 sheet metal screw instead of a #4 -- the hole stretched, but did not crack.

- The PCB bottom screw hole (center through-hole, bottom) is slightly larger than the PCB screw holes to prevent the cracking that PBJ noticed in one of the v0.02 prints.

If you print the part and have problems with cracking:
- Change the related screw hole size variable(s) in lines 37-39 of the SCAD file
- Preview
- Render
- Output a custom STL

The consideration that some part designers overlook is that instead of removing a circular hole (green), the software removes an inscribed polygon.(blue)

(https://upload.wikimedia.org/wikipedia/commons/8/85/OpenSCAD_Under_size_hole.jpg)

The number of sides of that blue polygon is controlled by the variable "$fn=" -- the number of fragments used to render a full circle. (Line 41 of the SCAD file)

To produce a hole like the blue hexagon in the picture above, use "$fn=6".

For an octagon, use "$fn=8".

For a 180-sided polygon, use "$fn=180" -- I know it's overkill, but this is a small part so the render time is still reasonable.

Title: Re: So ... 3d Printers....
Post by: Howard_Casto on April 15, 2018, 01:19:29 am
Yeah I've ran into the polygon issue already with my 3d printing adventures.  I made a sort of hub to hold  a detachable star wars yoke for my racing rig and upon the first print I was disappointed to find I had wasted two hours printing a blocky mess that the neck of the yoke wouldn't plug into... cranked the poly count for the cylinder up to 180 and it was fine.

Here's a weird one.   :dizzy:

PBJ asked me to print this (https://www.thingiverse.com/thing:87920) Bally drop target from thingiverse.

I loaded the STL into Cura and turned it on it's side to reduce the odds of layer separation breaking the spring loop.  (supports and raft enabled)

(http://forum.arcadecontrols.com/index.php?action=dlattach;topic=149895.0;attach=367784;image)

When I tried to print it . . . fail.   :banghead:
(I stopped it at around 75% and removed the raft and supports)

(http://forum.arcadecontrols.com/index.php?action=dlattach;topic=149895.0;attach=367780;image)

The loop part of the model was "negated" (solid center, no loop  :dizzy:) and a slot ran down the middle and cut into the semi-circle under the target.

Re-loaded the model into Cura and normal view looks OK, but layer view shows the "negated" loop and slot down the middle in place of the center ridge.

(http://forum.arcadecontrols.com/index.php?action=dlattach;topic=149895.0;attach=367782;image)

Can anyone duplicate this?

Is this a problem with the model or is it caused by the old version (IIIP-i3?) of Cura that came with my Monoprice Maker Select V2 printer? (Wanhao Duplicator i3 clone)

I probably should have asked this earlier, but which pinball machine are you repairing?

There are several versions of the Bally drop target.

The model we've been working with is a flat-top (a.k.a. tombstone) version with no spacer nub at the bottom.

The picture you posted is the ramp-top (a.k.a. hood or ledge) version with a spacer nub at the bottom.

Fathom (http://www.marcospecialties.com/pinball-parts/A-3944-34SET12), Black Pyramid (http://www.marcospecialties.com/pinball-parts/DT1082), and Spectrum (http://www.marcospecialties.com/pinball-parts/DT1690) are the three pins I've found that use the green drop targets you mentioned in a PM -- all three use the ramp-top version.   :dunno

I've been obsessed with trying to get the tweaks right with the settings.  Printing lots of tiny stuff.  There's a lot to absorb!  I feel like I should try to set up octoprint before I try anything large. 

And your experiences were especially helpful!

Octoprint is super easy to setup and use. Let me know if you have any questions about it.

Anybody have tips for success printing something thinner than 1mm?  Like maybe down to .6mm?  ---steaming pile of meadow muffin--- starts to get weird down there...

What issues are you seeing?

I've been printing custom badge holders which most have very thin text or art work. It took me several passes to figure out the best settings. Fortunately, I use Simplfy3d as my slicer, it has some great options for Thin Walls.

You can try keeping your Nozzle at .40 but change the extrude diameter to .30. Keep in mind that if you cant setup multiple processes per layers then the entire model will print with that setting.

Thin and slow first few layers work well for me with no fan cooling.

I print at 0.2 20mm/s no fan for first 3 layers.
Title: Re: So ... 3d Printers....
Post by: JudgeRob on June 28, 2018, 11:08:28 pm
The prints are flimsy which is sort of expected at that thinness, but holes in the print and like the nozzle smears it around kind of.  I'll upload some pics. 

I'll try shutting off the fan.  Didn't think to try that...

Here's what I'm getting.  The one on the right is closer to 1mm.  Less than that and I get the other results.  (Those are supposed to be Galaga ships)

My best guess would be a combination of your nozzle being to far away from the bed and/or your under extruding.

When its putting down the first layer it should be squished right down so the top is flat.

Can you go to 0.5mm on your printer?
Title: Re: So ... 3d Printers....
Post by: BadMouth on June 30, 2018, 03:34:47 pm
I'm no expert, but just looks like a bad first layer to me.  First thing to check would be the level of the bed.
Looks like the nozzle is too high or the filament isn't melted enough.

I don't have the same printer, but have a .4mm nozzle and my first layer is .3mm.
Check the first layer settings in the advanced tab of Cura.
There is also a setting for initial line width there.  (mine is set to 100%).

You can see the lines on mine, but gaps are rare.
I sometimes print thin .5mm breakaway tabs to hold smaller prints down and they always come out solid.

EDIT: print speed is set to 40 and bottom layer speed (under advanced) is set to 20.
I think I usually print stuff faster than this, but those are the settings currently in there.

how big?
at a little over 5" tall it'll be a 24hr print.
I can give it a shot during the week when I don't care if the printer is tied up.
I did a test print with some cheap crappy brittle PLA that breaks during printing.
not too bad.

(https://cdn.shopify.com/s/files/1/0245/5519/2380/files/PHOTON-03.jpg?1408)

If anyone has questions about it let me know. Main things to note:

Smell is terrible, you cannot be in the same room with it. I printed a huge carbon filter which helped tremendously but you can still tell.

Clean up is a bit annoying, but once you have a nice setup its not that bad, basically gloves, 2 bath buckets of Isopropyl alcohol and a Curing station.

Post clean up is so much better, just pull off supports and a very little bit of sanding depending on how the supports came off.

Latest print: Zero sanding, just washed and cured. Detail is amazing

I was looking at these, but the new ones are totally new and the intertubes is pissed off over it.
new control board, newish design and models of old photon are not compatible.
which, if you never owned one doesn't matter I believe.
I don't need one but i expect i'll get one eventually just because.

but damn.
can't even come close to that detail with a .4mm nozzle and .16 layer height.
might come close with a .2mm nozzle but it will take a whole lot longer to print it i'm guessing.

They are gettin' affordable! Great option for hobbyists in the tabletop and modeling hobbies, it is pretty much cheaper to go with a resin printer to make figures than buying them to paint.

I know I would have bought one already had my original filament printer not kicked the bucket.

if it were to be printed in half or one piece I think so.
tree supports aren't too bad though.
You will be able to get him a much nicer print for sure.

i'm going to clean that crappy yellow filament out of my extruder teeth and give it a shot at a smaller size like 3 1/2 inches long.

those look amazing.
how long to print?
after many issues with my hot end i'm starting to print parts for this now.
got some nice shiny silver filament.

The largest one was 7 hours.

LOL!
20hrs on mine at .16 mm layer height at default size.
each section is taking 3.5 hrs min. for me.

So this came out better than expected.
Too bad I printed it with supports on the bottom that wonít fricken come off.
Reprinting upside down with tree supports.
Generating then in meshmixer took about 45 mins.
Then slicing it in Slic3r took almost an hr.
Had to slow down support speed to 30 mm so they donít get knocked over.

I found some models for modding an N64 case with usb front connectors, feet, switch ect and a tray for the rpi4.
I didn't have an n64 case and busted n64's are $25 on ebay. I call that plan B.
however I had already bought that lime green spool for $12 shipped on sale and the kids loved the color so i found an n64 model and printing that.
it isn't 100% accurate (off a few mm) so i need to do some adjustments on the fitted parts.

Success!
though i'm wearing gloves for removing supports from the top piece.
Had to use a needle nose and channel locks to remove them and that plastic is sharp.
chewed up my fingers.

Think i'll start a project thread now.

Here's a modded version of the base for anyone wanting one without the button hole.
- The button is for the Rhea or Phoebe Saturn Optical Drive Emulators, not the Fenrir.

Ah, so it is using one of those SD cables with the screw mounts.  Glad I didnít order one just yet, though i suspect if you crack open the plastic case found on some of them, you find the screw mount version inside.

Anyway, purpose of this is to move the SD card slot to a more reasonable position, reduce wear and tear on the optical drive emulator micro sd port, and plug up the gaping hole left when you remove the CD drive.

The guy that posted the model on Thingiverse described the extender he used as "a 25cm one" -- no links or pics.   ::)

The screw holes in the base align with screw holes in the edges of the cover. (34mm center-to-center)

The hollow under the cover is 30mm wide x 37mm deep x 4mm tall.

I have an SD card extender like the pic below, but the plastic case makes it too tall to work with the cover.   :banghead:
- Looks like the cover was designed for a low-profile regular-size SD card holder.
- Not sure if he used something like this one (https://www.amazon.com/Extension-Adapter-Flexible-Extender-UHS-III/dp/B088NNVWQ8/) that has no case or decased one like mine.   :dunno

(https://images-na.ssl-images-amazon.com/images/I/61HXoyQv4PL._AC_SL1200_.jpg)

If you can't find an extender that works with the cover dimensions listed above, it shouldn't be too hard to make a custom cover.

I'm pretty sure on the dreamcast versions of these prints you take the cover off the extender but I'm not 100% sure. 
Title: Re: So ... 3d Printers....
Post by: PL1 on August 03, 2020, 05:37:23 pm
Since the SD card extender I mentioned above is too big to fit without decasing, here's a cover for MicroSD card extenders like this one (https://www.amazon.com/LANMU-Extension-MicroSDHC-Monoprice-Raspberry/dp/B07WWVBK8V/) (7.5") or this one (https://www.amazon.com/LANMU-Extension-Extender-MicroSDHC-Raspberry/dp/B01D9J8KQE/). (19")

(https://images-na.ssl-images-amazon.com/images/I/61YntwHCOzL._AC_SL1200_.jpg)

The .zip file contains the STL file and the OpenSCAD, DXF, logo image, and Inkscape files along with directions on how to vectorize a logo for OpenSCAD if you want to customize yours.

The OpenSCAD file is fully commented and parametric so you can easily customize the cover by changing the associated variable(s) -- no programming ability needed.   ;D

Print the cover with the small, flat back side down with no supports. (i.e. rotate -90 degrees on the X-axis.)

This cover is about 3mm taller than the original, but it should still fit inside with the CD lid closed.

After a lot of trial and error I have a refurb monoprice mini delta with a glass bed and a .2mm nozzle printing up some decent quality mini's in PLA.
I made a bunch up to use with Dungeon! Classic board game from early 90's.



Title: Re: So ... 3d Printers....
Post by: pbj on August 08, 2020, 07:58:14 pm
Had to take a soldering iron and hobby knife to it, but got it mounted.  Holes were a little too tight, and thereís some alignment pegs on the case that were blocking it.  I think the original author snapped his off or maybe his console revision didnít have them.  So I melted out a notch and waved the shaft around in the holes to widen them and good to go.  I tacked it to the case with a few drops of hot glue, and used two tall mounting posts in the back and two short ones up front.  Used 2 8mm M3 screws to hold the SD card cable housing to the plate.

You have to twist the SD cable to get it turned the right way internally but no big deal.

Looks great and will protect my internals and keeps my hands off the Fenrir.

Thanks, PL1.

If anyone printing their own has this problem, LMK how much larger the holes need to be and measurements for where and how big to make the alignment notch.

I'll update the OpenSCAD code here (http://forum.arcadecontrols.com/index.php/topic,152421.msg1719622.html#msg1719622) with easy-to-adjust variables for modifying the original base.   ;D

I started out with good intentions and my drill press, but I was afraid I was going to blow out the edges of 3 of the holes so I went to the soldering iron.  Iíd make the holes bigger and expand them inward.  Itís not much.  I have no idea how youíre supposed to put it all back together without securing the insert to the top case first.  Probably just a little masking tape would have been fine as itís really clamped in tight once the case is screwed together.

It'll be easy to reverse engineer the current X/Y position and size for the four mount holes -- then anyone can adjust those variables as needed, render, and export as an STL file.   ;D

I can guesstimate, but the three measurements I'd need to make the notch accurately are:
  1. The X-axis distance from the right edge of the base to the right edge of the notch.
  2. The X-axis width of the notch.
  3. The Y-axis depth of the notch.

Stretched the bed of my monoprice mini.  Waiting for the mailman to bring a longer belt today.  Original bed will attach to adjuster screws shown.  Piece of glass cut from scrap will go on top to print longer stuff when needed.  Spent about $25 including the epoxy to attach the bed halves to some small J channel. Might spend a couple more on nuts and bolts to make thumb screw adjusters.(https://uploads.tapatalk-cdn.com/20201127/67539df6892375118745a6f53dcc3ac9.jpg)

Don't need to mess with the firmware.
Dimensions are adjusted under machine settings in Cura.
(Point of origin set by limit switches on machine, then dimensions in each direction from there are whatever is entered in Cura.)

While using the stock heated bed, I have a magnet stuck to the underside to trip the y-axis limit switch at the front edge of the shorter bed instead of where the longer glass bed would be. 

The only PITA thing with this setup is the height change when stacking the glass plate on top.
Either the adjuster screws will have to be tightened down and re-leveled to lower the glass to the current height, or I'll have to rig up some type of spacer or adjuster on the z-axis limit switch.

I may end up just making a full length bed out of metal, but I suck at working with metal and don't want to spend money on an additional bed heater.

I am no expert on 3D printing stuff.

What are people using for adhesion/build surfaces these days?

I don't print a whole lot and have been using PEI on a heated bed.  Did a lot of printing recently and my prints are no longer sticking.  After getting nowhere with a lot of unnecessary bed leveling & heat level experimenting I'm thinking my year old PEI sheet may be shot.  Everything prints fine on painters tape.

So should I buy another sheet of PEI, or are there better alternatives now?

I honestly have no idea how people splinter the glass beds.
Are they just trying to tear the model off with enough strength to lift the printer?

I just take a metal putty knife, slip it under one corner and give it a little nudge, then do the same thing on another corner and they usually just pop off.
my large Chiron has a dimpled bed so when it cools it usually takes care of breaking the model loose.
PET-G gives me the most trouble.

my straight glass bed on my mini sometimes doesn't want to let go but it's small so i just put it in the freezer for a bit and it pops off.

A friend who does property management found an XYZ Da Vinci Jr abandoned in an apartment.
this is a printer with NFC tagged filament.
costs about $40 for a 500kg roll.
so I can see why it was abandoned.

it actually prints pretty good and is fully enclosed.
I have an NFC tag writer and tags so i'm either going to try and follow the instructions for spoofing the tags or replace the board with something that doesn't require tags.
the manufacturer does sell an NFC tag of their own to unlock the printer but for almost $70 shipped and nope'd right out of that option.

this printer will go on the shelf until i figure out what I want to do with it.
may even just replace the board.
will take a lot of splicing though because the xyz doesn't use standard connectors.

I have an NFC tag writer and tags so i'm either going to try and follow the instructions for spoofing the tags or replace the board with something that doesn't require tags.
the manufacturer does sell an NFC tag of their own to unlock the printer but for almost $70 shipped and nope'd right out of that option.

this printer will go on the shelf until i figure out what I want to do with it.
may even just replace the board.
will take a lot of splicing though because the xyz doesn't use standard connectors.
Nice! Always fun to tinker!

Working on a personal project, just finished the prototype...
(https://uploads.tapatalk-cdn.com/20201225/ae2a814dbf910e96ac810096117eaabc.jpg)

The final version will be printed in wood. I need to adjust the size of the holes. But this print was good for me to break in all the new changes.

How much were your upgrades total?  I want to get mine back online (needs a new table) and I might as well do improvements as I go.

Slicer of choice?

I've just been using an older version of Cura that came with my printer.  Tried the newest version, but had better results with the old one.

An issue has surfaced that I believe is caused by underextrusion following a long unnecessary travel path taken by Cura.  I fiddled with some setting that made it remove some of the trips accross the object, but am curious if a different slicer would just make trips around the perimeter like I think should be done.
EDIT: Newest version of Cura takes a much better path.  Still interested to know what slicer people are using.  I downloaded PrusaSlicer, but have only tinkered with it a few minutes.

I personally like PrusiaSlicer but I think the the real trick is to pick one and learn to tweak the settings to give you the best prints.  Each slicer has its quirks and will need to be set up a little different. For some reason I never warmed up to Cura though many people love it.  PrusiaSlicer seems to be developing at a good pace but doesn't seem to break my old settings as new versions come out.

It was free. I'll probably source replacement PLA parts, or get the guy who gave it to me to print them up, just to enjoy rebuilding it.

It doesn't hold up very well in water either.  I made some brackets to hold the lines to my automatic plant waterers to the bottom of the reservoir.  IIRC they lasted a few months submerged.

Bought a roll of ABS when I bought the printer.  Still haven't opened it because I don't want to smell ABS melting.

Got a deal on some PETG, so we'll see how that goes when it gets here.

This trick is probably common knowledge, but for anyone who hasn't heard about it....

The McMaster-Carr (https://www.mcmaster.com/plastic-gears/) website has 3D CAD files for most of their hardware including screws, gears, brackets, etc.

Your process will vary depending on software used, but I am still playing in TinkerCAD so here is what works for me:
Download the file from McMaster-Carr in 3-D STEP format.  (A couple others I tried came out like swiss cheese)
Start a new project in FreeCAD and import the STEP file.
Select All and export to STL.
Import to Tinkercad or slicer of your choice.

This morning I'm messing around with plastic reduction gears.
Haven't printed or tried to use any yet.
I've used the process in the past to create screw holes with countersinking.


Title: Re: So ... 3d Printers....
Post by: SammyWI on January 23, 2021, 09:27:41 am
McMaster is a great resource for 3D CAD files.  But be cautious about the gear files they have.  I've looked at several and the modeling of the curved gear tooth is an approximation in the CAD files and is not a true gear tooth form.  This may or may not be an issue depending on what your use is for the parts.

I'm a Mechanical Engineer and I do spur and helical gear design as part of my job.  The approximation that McMaster does is pretty common for 3D modeled gears.  In manufacturing most gears (not 3D printing) the manufacturing process makes the special curve of the gear teeth just by the nature of how the process works.  Hard to explain but it was found many years ago that the complex shape of that curve can be made with relatively easy to make tools and processes.  But making it in 3D modeling software is very difficult.

I should be getting the parts today to upgrade my Anet A8 frame to aluminum! Iíve spent the past month really getting this machine dialed in, and this was the next natural step. Itís also the final step, as I plan to save up this year to build a Voron by this time next year. Iíve really enjoyed how much Iíve learned about 3D printing these last few month. The trick is to find someone just as enthusiastic who knows more than you and is willing to share knowledge! :)

Iím currently printing the connector parts for the new frame using PETG for the first time.

Just printed my first PETG parts an hour ago!

The shiny black looks better than the dull grey and blue PLA that I use for everything.
Parts seem soft/rubbery, but they are thin and were still warm when I made the observation.

Dunno where else to post this.  $9 worth of Semitsu buttons + $6 shipping to have proper color buttons for my $140 cnc machine.  I seem to be drawing out the process of setting up the machine and 3D printing accessories rather than learning how to use it.  I did learn how to set up and calibrate the machine in grbl so that's something.

Once mine dried, they were rock solid.

Theyíre joints for the metal frame, so theyíre thick, but they feel more solid than anything Iíve done with PLA.

FYI, if you need just a little filament in various colors for a few small prints, do not be tempted to buy the polaroid pen pla at Joanne fabrics.
I got some polaroid PTEG and it seems great.  The interwebs says that they buy and rebrand from wherever they can get a deal, so the quality is not consistent.

Some colors print fine.  Two of colors I need clogged my nozzle repeatedly and eventually bonded to the PTFE tube inside the heatbreak.
Kept going higher with the temperature hoping to get it to stop clogging.  Maybe I cooked it.
Printer is down until replacement parts come.   :cry:

get the Capricorn or Capricorn clone PTFE tube.
it's usually dark blue. get the cutter. it's worth it.
i also use it for small engine gas line (whacker and chainsaws) when replacing carburetors.

I had to replace the white one on my printer after trying to print pet-g.
when i pulled the white ptfe out it was almost black on the end and the hole had narrowed so much filament wouldn't go through it.

I saw bowden tube size, but none as small as what's in my heatbreak (3mmOD,  1.78 or 2mm ID).

Cheap heatbreak replacements with ptfe inserts will be here in a couple days, but after reading up on the subject I decided to order a genuine 3DP V6 all metal hotend.  The old mp mini select probably isn't worth the upgrade, but I felt like it was going to nickle and dime me to that amount of money anyway.  The V6 bracket was the first thing I printed, as is recommended.

it sounds like your mini and my mini delta use the same hot end.

A good, upgraded Voron will run you over $1000, but the quality is impeccable. Thatís why Iím playing the long game with that one.

Iíll keep the Anet as a secondary printer, but itís definitely evolved from the stock version!

After installing a new heatbreak with fresh ptfe liner, the mini select was back up and running with my usual filament.
Tried to print the polaroid pen filament again and it clogged again.  In the process of clearing that, I assume that I damaged the thermistor wires because the temperature showed maxed out.
Shows maxed out even without the thermistor plugged into the main board.  From what I read online, the main board is now bad.
So I have a $60 hotend on the way for a 5 year old $150 printer with a bad board.  :timebomb:

I could swap in a ramps setup (with learning curve), but at this point I'm sick of working on it and sick of spending money on it.
The hotend I ordered is 12v, so it will only work with certain printers.  The return policy (printedsolid) says they only process returns once a month, so a refund might take that long.
ugh......

I'd get an Ender 3, but they are 24v and the whole wheel/guide setup just doesn't seem like a good system to me.
Settled on an Anycube Mega S.  Not as much support for it, but it's ready to print after attaching a few screws and it's 12v so I can still use the e3d v6.

After watching a bunch of videos, I'm digging the new style hot ends like the slice mosquito that aren't a bunch of cylindrical parts screwed together.  They bolt on straight and don't twist, so you don't have to grab the heater block with channel locks when screwing in a different nozzle (and end up shorting out the thermistor circuit in the process).

After getting educated, it seems to all come down to a smooth bore finish and keeping everything north of the heater block cool.  I'm thinking there are other ways to accomplish this that require elbow grease and less money.

I could have sold you mine!  Of course it wouldn't get there as fast.  I think I'm going to try a micro swiss heatbreak in the stock hotend before swapping over to the E3D.

I'm starting to regret ordering directly from Anycubic for the sake of warranty and after sales service.
Haven't received anything since the original order confirmation.  Emailed them today and received no response.  A quick google search reveals that this is pretty much par for the course.
No response or shipping information, then the printer will just show up in 3 or 15 or 30 days.  If I can't get in touch with them about whether it has shipped, I can't imagine the warranty service is worth much.
Should have just ordered from a 3rd party seller on Amazon and had it delivered in 2 days.

I'd never heard of the Voron before you mentioned it.  Whenever I get a cheap printer up and running, I'm going to start planning for a Voron.

My friend that built it is very thorough in her research and process. When she decided to get into 3D printing, she went straight for a Prusa and learned on that. She used the Voron recently to print a filter for her telescope, and I was blown away by the quality and complexity of the print. Thereís no way my Anet could even approach that. I could probably print a nice spacer block to put under each telescope leg to raise it an inch!

I kid, but that what it felt like! Iím definitely going to start planning for my Voron. I want a nice big 330x330 built platform.

We have uploaded the product you bought,
and we will transport it for you soon, but the tracking number has not yet come out, please wait patiently
....yeah that thing is still sitting in China.  US warehouse ---my bottom---.
They followed up with a "DHL tracking number" that is actually a UPS tracking number, but I'm betting they've only printed the label.
We'll see if it gets scanned into the UPS system on Monday.

I want to get the MP mini select back up at some point, but have decided that I will not spend any money on parts unless they can be re-used on a Voron build.
I watched some videos on installing Marlin on the SKR v1.3 board the Voron uses and the learning curve doesn't seem bad at all.
Between those and details given in a MP Mini Select to Ramps instructables, I'm pretty sure that I can get the SKR board running the Mini without too much hassle.

So I've ordered the SKR v1.3 board, Fysetc display and 2209 drivers spec'd in the Voron 2.4 BOM with the intention of using them with the mini for now.

EDIT: got an email from UPS that the package is scheduled for delivery tomorrow, but the tracking number shows not picked up yet.  Email source seems to be legit.  It would be awesome to get it tomorrow.

Hah - I started an Amazon with list with Voron parts! I have a $50 gift card I got for Christmas that I think Iím gonna use to buy the six stepper motors.

Mega S got here tonight, but it's still freezing cold from being in the UPS truck so I'm going to let it acclimate before turning it on.
For all my whining, delivery time was only six days.  (the tracking number showed "on way to UPS" up until yesterday)

I have an anycubic printer.
check the fasteners on the parts you didn't assemble.
most of mine needed a few turns.

You weren't kidding.  Every single one needed at least a half turn.

Just printing some last minute items, but everything is ready for the transition to the metal frame. I might start as early as today, but really thinking about making it an all-day Saturday project.

Comparing the metal frame of this Anycubic Mega S to the 20x20mm extrusion frame of my mini CNC, there is no comparison.
Although thick metal, the stamped steel L flexes like crazy compared to the extrusion which has no noticeable flex.
Extrusions all the way.

Yeah, Iím excited to get this done. I opted to go a bit longer on the Y Axis, so I ordered some new side extrusions that should be here any minute now. Canít wait to tear down and start rebuilding!

I think I got my moneyís worth out of this spool of PETG.... :)

I had ordered a small piece of extrusion from Amazon to test a few things out on, but after checking Misumi's prices I cancelled and did a larger order from there.

Wasn't going to mention it yet, but I dug out some new old stock NSK linear rails that a friend gave me a few years ago for helping them.
Was saving them for a CNC machine, but decided to see if they would work for a 3D printer.  The rails are huge, 40mm wide and thick.  The blocks only have threads for 3mm screws though, so I'm not sure they are fit for a bigger CNC router.  Surely overkill, but man are they smooth.  Zero play also.  Got two 740mm rails with 2 blocks each, so if I cut them in half (gasp), I'll have four <370mm rails.  They are too heavy to be on any moving parts, but could be used for rails that attach to the frame.  I could use them for the Y and Z on a giant Voron 0 or use them all on the Z axis of a Voron 2.4.
Thinking that a 40mm wide guide could be easily aligned on a 2040 extrusion, I ordered $100 worth of stock to play with from Misumi (three 2040x1000, six 2020x1000).

So I'm headed down the road to committing the Voron sins of using the wrong parts and cutting/drilling/tapping my own extrusion.  I don't think it will be that bad.  I'm tapping holes that are already there.  The holes drilled in the extrusion don't need to be precise. They just need to line up well enough for an allen key to reach the head of the button head bolt on the other side.  As far as getting the cuts straight, I have a table saw sled calibrated this way (still plan to keep track of the factory edges and use them on the most important joints):

Yeah, Misumi is great. Ordered Monday, I already installed the longer pieces. Time to slowly tear down the acrylic frame.

oh yeah. once i tightened everything up prints were good.
Also, when my chiron showed up the mail lady knocked on the door and asked if i'd pull it off the truck.

so, it turns out with the XYZ 3d printer i was gifted, if you just use cura to connect to it, it ignores the NFC chip in the spool you buy.
also, it's actually a damn good printer.
it's trowing out .10 per level D&D miniature's at acceptable quality (at 30mms) with very little adjustments.
it took a weeks of tweaking on my mini delta to get solid prints.

that last update allowed you to use cura instead of their in house slicer.
they do have an open chip they sell for $60 shipped but i found i don't need it.

I printed up a spool hanger for the outside, drilled a hole in the side and designed a simple guide with no edges for the filament.
then i just manually leveled it.

It's alive!  No idea of it's accurate or can print, but the steppers are all moving in their proper directions.  Pretty sure the numbers I put in Marlin from the mpminiselect wiki are reliable.  Only part I had trouble with was the Fysetc Mini 12864 V1.2 board.  The tutorial I was following used a different LCD and there were some settings under NEOPIXEL_LED that I missed.  The bigger thing was that the connector on the board is upside down from what it needs to be when used with the skr1.3 board!  Finally came accross it on the Fysetc website. 

Tomorrow V6 gets installed and then I'm sure it's lots of tweaking.  Hoping this can be a dedicated ABS printer with which to build parts for a bigger ABS printer.  (It is on a chair because the USB cable that comes with the skr board is like 1ft long) (https://uploads.tapatalk-cdn.com/20210207/54c42c7dbe60c694baa3d49e9e3d80b0.jpg)

I picked up an MPMD for cheap that someone bricked while trying to update.
so i put the custom firmware on it that is out there in the community that lets you use a 10 amp power supply to heat faster and higher.
took multiple tries to get it to take but it did.
thought i'd have to buy a new mainboard.
didn't have an old SD-card that it would read when booting.
had a micro-SD to SD adaptor cable and a 1gb SD card.
it worked!
ran the calibration program and so far it's printing good now.

Also, found out i'm getting a small bonus from work next week so i'm going to pick up a 2k mono-screen resin printer.
they are ~$200 now because everyone is about 4k.
looking at the voxlab Proxima and a led UV light with a light activated turntable.
just need a homer bucket to line with tin foil for a curing station.

I'm just printing mini's for D&D and skirmish games so i think i'll be good with just a paltry 2 k. :)

Let me know how the V6 install goes. I plan to do mine in the next week or so.

Did the frame conversion this weekend - I love it! Everything is nice and sturdy. I also upgraded the LCD - man, so much better than the stock Anet LCD. The dial works so much better than those crappy buttons.

Waiting for a new MOSFET to show up for the heater bed, then I can try a test print.

Let me know how the V6 install goes. I plan to do mine in the next week or so.

V6 install was gravy.  Started to watch a tutorial on youtube, but my parts were a bit different, so followed the official guide: https://e3d-online.dozuki.com/Guide/V6+Assembly/6?lang=en (https://e3d-online.dozuki.com/Guide/V6+Assembly/6?lang=en)
The firmware update would have been a sticking point if I had not already been changing and compiling Marlin the day before.  (If I hadn't fried the original monoprice board, it would have been one line of gcode to change the thermistor value).  Everything with the hotend went without a hitch.
The mount I used was literally the first thing I printed when I got the printer years ago because people online recommended doing so in case the hotend when bad.

The mini display continued to throw me for loops. My axis were reversed when I tested them in the menu, so I inverted them in Marlin.  Then homing was reversed.  I try to reverse homing, but it throws errors and can't be compiled.  Then I find out that the encoder wheel on the display can be reversed....and the direction the menu responds when the wheel is spun can be reversed.  Then I get where I think everything is right, I open Pronterface to my first PID tune on the hotend. ...and the axis are reversed there...meaning they were correct to begin with.   :dunno  So I go back and make sure everything is right in pronterface, then change the wheel and menu settings to work with that.

.....and then I struggled for hours (still struggling) to get my limit switches working.  It should be the simplest thing.  It's just a NO microswitch.  Tried everything and it was like they weren't there.  Then discovered that I was supposed to have jumpers on the board.  Then they showed always closed so I inverted them, now they show always open regardless of whether they are pressed or not.  I know I'm a bit in over my head, but setting up friggin' limit switches shouldn't be the difficult part.  :hissy:

I could be printing on it if the limit switches (and homing) would just work properly.

Cobbled together a lcd case and card holder from thingiverse with a plate in tinkercad.  Board is just on standoffs on the base plate.  Got a 60mm fan wedged in one end and no cover on the other end.(https://uploads.tapatalk-cdn.com/20210207/e828bc34dc708302a828a50ec9b14275.jpg)

Heh.

I just got the MOSFET wired in, but I belt getting heater errors. I checked, one of the power cables was unattached at the source. Tied that in. Still nothing. Found that a connector was off by a pin. Fixed that. Finally the heated bed was recognized. Sweet!

people are dreaming these days with what they want for a broken 3d printer.
I got mine on ebay before prices on everything went sideways.
should check craigslist and fb market place.

Well, I think the mini select is fully back now.  Laying down some petg as I don't want to open( or smell) the ABS until I'm ready to print parts.  Didn't know what to do with the rubber duck that came with the bigtree board, so I turned it into an extruder topper.

Man, this thing is near silent with the new board.  Only thing making noise is the hotend fan and it isn't much.  Gonna have to hack the obscenely loud anycubic mega s despite the warranty.(https://uploads.tapatalk-cdn.com/20210209/f8e00e5f37e334bdcc43f26788370f3e.jpg)(https://uploads.tapatalk-cdn.com/20210209/8e5e84db01272ec10951309b5a3ae9bf.jpg)

Is there some type of criteria the cube has to meet which means that you are ready to start printing voron parts?
If not, is there some other test to make sure the parts I'm printing would be up to standard?

Actually, I started using a new Slicer that I love. Itís called SuperSlicer, and itís a fork from the Prusa Slicer development. It has built-in calibration tools, and one of the options letís you print a Voron cube.

I like it so much better than Cura. You can really get in there and control almost every aspect of your print, filament, and Gcode settings. Check it out.

Wanted to share this with you guys, my friend sent this to me this morning. Sheís printing a pinball topper on her Voron while printing replacement parts to go to a full metal frame for the Prusa. I think this gives you a good idea as to the scale you can achieve on the Voron.

Nice.  I want one.  Gonna try to print some Voron pulley system parts on the mini this weekend.  Hopefully they turn out useable.

Been a bit disappointed with the Mega S.  I've gotten by with it, but couldn't seem to get any aspect dialed in.  Couldn't even get the bed level without the back corner knob loosened so much it would fall off. 

Turned out the Y axis plate was bent in multiple ways.  Was afraid I wouldn't be able to straighten it, but it turned out to be some weird super soft metal that bends easy.  Got a decent first layer now, but still have a long ways to go.  While IMO the design of this printer is superior to the Ender3, I can't say I recommend it.  Too many quality control issues and it makes a high pitch whine that won't allow me to get a good night's sleep with it running.

my Chiron has the same thing with the Y stepper or bed motor.
I've already replaced it and it seems like the the mount is bent so i straightened it and it seems to work better.
but it squeaks.
not that much.
i'm in the next room watching TV and i have to look to see if it's still printing.
but it's next to my Work From home setup and i notice the squeak some times.

my MPMD's squeal so i can hear them in bed upstairs.

Printed a Voron cube in ABS last night to see if the mini was up to the task.  Turned out great except for the bridge on the inside.  Thought I was ready to start printing parts.  Bracket looked good when I left it.  Came back to a lifted and warped corner.  Thought I could get away printing on a 75 degree bed since it was sticking.  Guess not.  Despite being warped it is crazy strong.  Gonna crank up the heat and build a foam wall.  Extending the bed is coming back to bite me in the ass when it comes to building an enclosure.(https://uploads.tapatalk-cdn.com/20210212/5bd10e71f6350151b37097874136826c.jpg)

I have a heat lamp clamped to my Chiron and that usually lets me print smaller ABS parts just fine.

It prints a LOT better. A lot faster too, since this sturdy frame isnít subject to the same wobble and sway of the acrylic frame.

I like the heavenly glow.  I can't wait to have something dialed in again.
Despite raising the maximum bed temp in the firmware, the bed of the mini topped out around 77 degrees.  It would go higher but not stay there.
A layer of rockwool (safe n sound) under it made a huge difference.  It made and maintained 80 no problem, then 85, then 90.  Then I started to worry that it was only designed for 80, so I didn't go any higher.
(the bed is actually a PCB with a thin aluminum sheet on one side).
Shortened the bed extension back to original size & bought some foil coated fiberboard insulation to build an enclosure.
Haven't attempted ABS again yet, except for running test prints for Marlin settings.

Bought a spring steel sheet with magnetic base for the Mega S.  What I didn't think about until after it was done is that it is only going to be as flat as the plate it is attached to.
So it isn't as flat as the original glass "ultrabase", which I had problems removing large flat prints from.  It's not horrible, a slight hump in the middle where the first layer goes on too thin.
Not sure if I'm keeping it or not, but the smart thing to do would have been to mount the magnetic sheet to a piece of tempered glass instead of the printer bed.

My resin printer showed up late saturday after being on an amazon truck all day in 15 deg weather.
I left it sit out on the table all night to let it acclimate.
opened up the bottle of water soluble resin i bought with it and hollee heck it smells.
kids were complaining.
so i'm waiting until they go to their mom's tonight to play with it.
I've read the regular stuff smells even worse.
good thing i worked on my basement this weekend.

i have a long bench down there i can almost get to. :)
i have some insulation board and steel 2x4's I plan to use to build one giant enclosure for all my printers and use heat lamps to warm it.
looks like I need to add an exhaust fan to it now.

only cost to me is the plexi for the front and maybe a new surface for the bench if I can't sand it smooth and paint it.
I haven't seen the top in 5 yrs so no idea what it looks like. LOL!
And it looks like I can sheets of 24"x48" lexan for 32$ at lowes.
it's .08" thick but i really just want to keep air movement and temp changes from happening while being able to see what is going on with the printer vs really insulating it so it should be fine.

Yeah, Iíve been looking at steel spring surfaces as well. Iíll probably do the mount it to glass thing.

Back in December I invested in this, and itís been great. Itís seems pricy until you realize what you get. How many sheets you get, and how much a much smaller roll of blue painters tape costs. Once I get close to running out of the stuff, Iíll look at getting a steel spring sheet.

(https://uploads.tapatalk-cdn.com/20210215/90f562c1e45ba5a0d3efd05e1704e27f.jpg)

The price is actually gone up three bucks since I ordered.

Hereís an example of what it looks like in use. I love it because I donít have to worry about any unsightly seams from tape or anything like that. I just lay down the sheet, and everything proceeds nicely.


Hereís an example of the PCB cage Iím printing right now, you can see how everything lays down nicely on the single sheet.

That is a sweet looking pcb cage.

Removed the magnetic sheet from the Mega S.  The adhesive was a huge PITA to remove. Reinstalled the stock glass ultrabase.  Clipped the PEI/spring steel sheet on top of that using binder clips.  Had to cut out around the clips that hold the ultrabase on, but now I have a removable flexible base that is flat.
So FYI, you can get away with just clipping a spring steel sheet on without using (or buying) the magnetic base.  The one I got was flat enough anyway.

While I'm not a fan of binder clips, I'm much happier with this setup.  It is much flatter that using the magnetic sticker on the bare slightly domed buildplate.

Nice - yeah, that glass i bought was a nice upgrade. I also picked up a new bed to replace the stock Anet one.

I love how much cleaner it makes things already.

I have two more major upgrades planned for this. The first is a swap out the power supply, which Ialready have and just need to do. The second is to install the V6 hotend, and what Iím gonna do is actually build the Voron Afterburner extruder, and then mount it to this 3D printer. Thatís a big, radical departure, and Iím excited to do that one. Iím going to print the parts in PETG, so weíll see how it goes!

I usually read this thread but don't participate.  One of the best things I did 5 years ago was bought my son a cheap 3D printer for Christmas.  Within a week he wanted a nicer one asking for an Ultimaker 2.  Another forum I was on had a similar thread and someone had posted build plans and a parts list for a UM2 clone.  So I told him I would buy the parts if he built it because I thought it would be a good learning experience.  He had to use the cheap printer to print a lot of the parts.  He made me buy him Simplify3D and he now runs it using a Raspberry Pi server I believe running OctoPrint.  So now whenever I need a part I design it and email him the file.  I never really learned how to use it myself and its been nice not needing to.  It doesn't have a bed leveler and I've watched him when the print starts he eyes it real close and reaches under making a couple fine tunings to the screws.  Not sure why but he seems to do this at the start of every print.  I attached a pic of what he built when he was 16.

Thatís cool, brother. Iíve really enjoyed tinkering in upgrading the cheap printer I bought. There is some satisfaction in making something better.

I used to do the manual thing before every print too, then once I added the aftermarket auto bed leveler, itís been send print and forget - itís been the best!

That's a VERY clean print up there Yots.
my last rpizero print had a few strings in between the vents.


resin printer is up and running.
but man the Ball Joint leveling system the voxelabs proxima uses....i cannot recommend just for that.
took me 2 hrs to get it level.
it uses a set screw on the front and side along with a screw on the back which just keeps the ball from falling out and shifting when you crank down on the other set screws.
took a bit to get the back screw to the point where it kept the ball from shifting but not pushing it forward and keeping the build plate from popping up on a corner when you tightened the screw.

the other resin printers with the 4 screws seem like it would be a lot easier.

anyway I printed the test file NP.
printed a really tiny zombie an inch tall (i forgot to scale the model) now i'm printing something bigger to see how that goes.
smell actually is not as bad as I expected, can only really smell the resin when right next to it or i take the top off.

Looks like a dream build for most people.  :cheers:

I'm about $750 into it with probably another $300 to go.  Credit card company started stopping the charges about 5 orders in on AliExpress.  The Misumi site allowed me to order the black anodized extrusions, but they won't ship until May.  So I am expecting to have everything here and build in May.  I bought an SKR 1.3 to get the Mini back up and running with the intention of using it on the Voron later, but now the BOM specifies a 1.4 (sourcing guide still links to the 1.3).  I will buy the electronics last in case something changes.

I originally wanted to cut my own extrusion and use linear rails which I already had, but customizing Marlin for my Monoprice Mini Select made me realize that I would not enjoy setting up the software side of a custom build.  With the Voron, everything is already worked out (hopefully) and I just need to follow instructions (hopefully). 

This is very much against my BYO nature, but I am sticking to the plan down to the colors.

Cool, glad to see youíre all in on the Voron. I plan to be there by the end of the year. Building the AM8 has been a good exercise for me. Plus, Iíll be able to print better quality parts for the Voron. Hell. I might even reprint some of the parts for the AM8!

And Iíll clip the zip ties once everything is wrapped up! :-)

scratch that, i shoveled snow outside for 45 mins, came in and i could smell the resin.

Well you know how fdm works.

I actually had a very high level understanding of how they worked but after seeing mine work here is the rundown.

resin printers have the build plate upside down.
that dips into a vat of resin with a clear sheet (fep) on the bottom.
under the vat is an LCD with a strong UV light as it's back light.

when you start a print the plate dips into the resin, pushes up against the clear FEP, the LCD turns on? off? the pixels that compose the first layer go clear (allowing the UV light to show through) and the resin cures.
build plate lifts and lowers for the next layer...rinse repeat.
Original models used a color LCD.
the latest is a monchrome LCd which allows for faster printing.
but i wouldn't know how it compares to a color.
Also, you can load the build plate up on these because half the build plate vs a full build plate = same amount of time to print because it does whole layers at once.

If you are level and everything sticks (supports are more important it seems so use a lot, they just pull off) you scrape the model off into your big Tupperware of water or rubbing alcohol depending on the type of resin and use it to wash all the excess resin off though people use Mr. Clean which is so much cheaper and easier to find.
sometimes you have to use an old soft toothbrush for bigger models.

pick off your supports then cure with a UV light.
I bought a UV spotlight and a light powered spinny platform together for this purpose.
Stuck them in a homer bucket lined with tinfoil taped in place with foil tape and hung the light from the lid with zip ties.
I literally just built it in 15 mins for my big print going now.

also, always wear gloves where resin is being touched (except when you touch your printers plastic lid) you use clean hands for that or it's etched forever.

Ok I've decide to build a Voron 300mm.  I asked my son if he wanted to build another printer and he said "do we really need another printer we don't use this one very much".  I said no I "want" another printer.  Then later I said well you might move out soon and want to take this printer with you so I'd like to have one here I can use.  The instructions have a few options to sort out.  It says we should print the parts in ABS and we've never used that material.  Not sure if I'd need to enclose the sides of the current printer.  My other idea was print it with PLA like he normally does and then once built reprint everything with ABS.  They also recommend using direct drive and he has a Bowden drive installed on the current one so not sure why they have that recommendation.  Seems like they encourage you to buy the chain instead of printing one.  I also see a hundred mods users have uploaded and wondered if I should just switch to any of those right of out the gate.  So many decisions.

So I placed an order with Bolt Depot for everything listed from there in the sourcing guide.  Then I went to mark what I had bought in the BOM spreadsheet and noticed the quantities did not match for 6 items.  I ordered some spares of everything but not enough to cover the differences on 3 of those.  <bangs head on desk>  Now I don't know what to trust in these listed quantities.

Update:  Found another post online with the same comment so apparently only use the BOM spreadsheet for accurate quantities.  Let my mistake help you...lol.  I called and fixed my order.

Ok I've decide to build a Voron 300mm.  I asked my son if he wanted to build another printer and he said "do we really need another printer we don't use this one very much".  I said no I "want" another printer.  Then later I said well you might move out soon and want to take this printer with you so I'd like to have one here I can use.  The instructions have a few options to sort out.  It says we should print the parts in ABS and we've never used that material.  Not sure if I'd need to enclose the sides of the current printer.  My other idea was print it with PLA like he normally does and then once built reprint everything with ABS.  They also recommend using direct drive and he has a Bowden drive installed on the current one so not sure why they have that recommendation.  Seems like they encourage you to buy the chain instead of printing one.  I also see a hundred mods users have uploaded and wondered if I should just switch to any of those right of out the gate.  So many decisions.
Hey Gil - good questions!

My friend, who is an expert with these things, has told me she thinks itís OK to build it out of PETG. PETG is a good middle ground between PLA and ABS. I used it for my AM8 upgrade and so far so good.

Iím going direct drive with mine. Her recommendation was to do so because there are less jams with a direct drive head as opposed to the Bowden set up. She knows what sheís talking about, so I trust her.

Itís awesome man. This Voron is definitely for you, not the kid. :-)

Cool thanks for the tips.  Yeah I like to be more involved in building this one.  I'm sure my son will get interested though when I start.  He was a kid when he built that last one but he's 21 now and graduating from UofA with a Computer Science degree next year.  When I said hey checkout this video he was like "oh its a CoreXY..." like he already knew more than I do...lol.

So I placed an order with Bolt Depot for everything listed from there in the sourcing guide.  Then I went to mark what I had bought in the BOM spreadsheet and noticed the quantities did not match for 6 items.  I ordered some spares of everything but not enough to cover the differences on 3 of those.  <bangs head on desk>  Now I don't know what to trust in these listed quantities.

Update:  Found another post online with the same comment so apparently only use the BOM spreadsheet for accurate quantities.  Let my mistake help you...lol.  I called and fixed my order.

I've never heard of bolt depot.
when i was building my printed CNC i ordered the hardware from the guy who created it because it was cheaper and supported his project but mostly because it was cheaper. :).
I had to deal with 2 different places and their shipping along with home depot and their prices.

i'll check this place out for my next build.

Yeah I was just following their "Sourcing Guide" that you can pop up after running the Configurator.  I didn't see any info about buying from the creator.

I think I spent too much and ordered from too many different places by following the sourcing guide. https://vorondesign.com/sourcing_guide?model=V2.4 (https://vorondesign.com/sourcing_guide?model=V2.4)
The shipping charges from ordering 1 thing each from 8 different places probably made up for any money saved.

Got my bolt depot order yesterday.  All bags labeled with description and quantity sticker on the front.  (might have even had a drawing, I can't remember)
I noticed differences between the BOM and sourcing guide, but only caught half as many as you.

I wasn't finding a good source for the build plate and the local machine shops I've tried in the past haven't been cool to work with, so I ended up ordering the kit from digmach (along with the DIN rails for mounting the electronics).  Probably paid a premium, but I'm tiring of placing orders for one single item.


In non Voron news, I printed an ABS fan bracket for the Mega on the mini and noticed that the end that curled up faced the tower.
The hotend fan was blowing air through the hotend toward the tower with nowhere for it to go.  The part that curled up off the bed was getting hit by the airflow redirected by the tower.
I moved the fan to the least worst angle and the part printed fine.  Still not attempting any more Voron parts until I have an enclosure built.

The bed of the Mega can get much hotter which has me wondering if I'm using the wrong printer for ABS.  I'm still struggling to get the print quality dialed in on it though.

Post by: Gilrock on February 17, 2021, 01:47:49 pm
Yeah well luckily 3 of the 6 items were wrong in the other direction so I already had enough on order.  I'd love to buy more items from less sources I've just been having trouble.  Even with just the fastener items it was looking like 4 to 5 orders.  I saw kits for some items like the extrusions but the number/length of the items didn't match the BOM so I avoided it.  Heck I'd probably give someone an extra 2 to 3 hundred just to order an all-in-one kit that was accurate.

Have you looked at enclosures? I did the IKEA Lack table hack but gave it my own flair. Most versions do all the sides in plexi but I wanted something a bit more industrial-looking:

I looked at some on sites where I was buying parts, but just chuckled at the big price tags.  I had not seen the Ikea table hack.  It looks good.
The mini setup will be temporary though. Bought a $14 sheet of 1/2" foil backed foamboard and a roll of aluminum tape.  I have piles of scrap optix left over from making cabs.
I want to maintain airflow through the bottom of the mini where the SKR board, Y and Z motors are.  It's gonna be ugly, but do the job.

Cool. I think I paid $12 each for three IKEA Lack tables, and I bought one 24 x 48 sheet of plexi. The 1/2 MDF I had on hand, as well as the black and white paint. I printed clips for the windows as well.

For the Voron they are showing two different types of T-nuts.  Hammer head and another style with a spring loaded ball bearing.  Wondering why I need both types.  I was about to order from Aliexpress but it was kinda expensive for just that part of the order.  Was considering the option of making the printed T-nut on Thingiverse where you just insert a nut.  Any thoughts?

Post by: Gilrock on February 17, 2021, 09:44:35 pm
Thanks....I already ordered the metal ones.  It wasn't as bad once I got home and took and took another look.  When I clicked on the Amazon links it was coming to like $96 for just T-nuts.  So like someone else said on my 4th transaction on Aliexpress it didn't seem like it was going through.  So call the fraud dept and wait 15 minutes to get a person then he says he doesn't see any issue on their end.  I try again and then it works.  He says you won't have any problems using that card now.  Very next transaction boom...fraud alert email comes...lol.  I gotta take a break and continue ordering another day.  This is nerve-wracking trying to sort out.

One question I do have is do you guys like 1.75mm or 3mm.  I placed an order for some nice red colored tubing for 1.75mm.  Then as soon as I hit the order button I notice another line item on the BOM that says I need to order PTFE tube with 3mm inner diameter.  Then I'm getting mad thinking I just ordered the wrong thing.  I keep getting tripped up trying to line up the sourcing guide with the BOM.
Title: Re: So ... 3d Printers....
Post by: BadMouth on February 17, 2021, 11:07:09 pm
Not sure about the bowden tube.  A quick search when I was shopping led me to believe that the larger diameter was because it is direct drive and the tube is just to guide the filament, not control it like when being pushed from behind.  I haven't ordered it yet, so would be interested to know.  IIRC, that was the order that wouldn't go through after the charge was rejected a couple times.

Stayed up until my bedtime making an enclosure for the mini.  It may or may not work, but it sure is shiny!  Optix window is double pane...'cause I got lots of optix scraps.  The sides of the base of the printer are removed and a fan is pushing outside air through it.

Against my better judgement I decided to start a print before bed.....and the skr board is dead.  LCD light comes on, but there is nothing on the screen and it isn't recognized over USB anymore.  Tried to reload the firmware via sd card and I don't think anything happend.  Apparently this is not uncommon with the bigtreetech boards.  There may be a chance to resurrect it over serial, but since it has only been used a week I am returning it to Amazon as defective.  They are shipping the replacement immediately and I have 30 days to return the old one or get charged for the replacement.  So...that might be a reason to order the boards through Amazon despite them costing a bit more there.

Post by: BadMouth on February 18, 2021, 06:05:59 am
I fiddled with the skr board some more this morning.  The firmware.bin file on the sd card was disappearing, so the firmware was updating.  There was hope!
Finally came across a post with something other than flashing the bootloader over serial pins (which is over my head, but I can follow instructions). 
All I had to do was comment out #define SERIAL_PORT -1 and uncomment #define SERIAL_PORT_2 -1
Sucks that I had already disconnected everything and removed the board, but it's good that it is working again.  Guess I'll have the two boards needed for the Voron build now.

Wow this Voron build is adding up pretty fast.  I'm at $882 and I've only ordered the Fasteners, Motion, frame extrusions, motors, and hotend.  Hope there aren't too many more big ticket items.  I know the build plate will be one.  I found a build plate kit but of course it was only available in the two sizes I'm not building and sold out for mine.  I did find a kit for the belts and pulley stuff then I go to finish out the one last line item in that section, the rails, and find out they will be $139 ($112 + shipping).

Yeah, when I said I was at $750 with $300 left to go .......I was mistaken.
Spent another $250 on the build plate/heater/pei/din rail kit and still haven't bought much from the electronics section.
It has to come to an end eventually.  :scared

I am working 20 hours/week overtime to bankroll this, but it still hurts. 
Need to sit down and add everything up and see exactly what has been spent and how much more it will cost.

Yeah what drive me crazy is almost every link for AliExpress goes to a different store.  I was trying to search for everything in a section to see if multiple items can be gotten from one place but I just lose track of all the tabs I have open and have to just start buying one by one and get $7 to $12 dollar'ed to death.  I was looking at the digimach electronics kit and almost was going to buy it but matching it up with the BOM a few things didn't match and they listed the SKR 1.3 vs 1.4.  Also every item becomes a research project.  I click on a link for what I expect to be a simple fan and get 20 options on the page and the sourcing guide doesn't say anything about which one to pick.  They might have different fan speeds, connectors, bearings, etc.

My comedy of errors continues....
Got the min back together and in the enclosure.  Even just the LEDs are enough to get it above room temperature.
Felt good enough about it to go straight to printing Voron parts.
The print starts and the nozzle is against the bed, so I relevel.
Then the print starts and the nozzle is against the bed.
And I realize that the V6 mount that I printed out of PLA is now floppy.  :lol

So now it's back out of the enclosure for the purpose of printing an ABS bracket which will hopefully hold up in the heat.
Good thing I have a couple months to get this all worked out.

EDIT: So the hotend fan isn't kicking on after getting the board working again.....

Post by: Gilrock on February 19, 2021, 08:04:59 am
Yeah I joined the Voron Discord server and was reading and searching last night.  I searched for the term PETG and after reading all the comments I'm convinced I need to try to use ABS parts for the Voron.  There was confession from one guy who was always advocating PETG was fine and eventually he ended up with some of the parts warping.  I got myself in the queue for the Print It Forward program where you can pay existing users to print the ABS parts but its about a 2 month wait in the queue.  I'm sure some of the parts I've ordered will take that long anyways but I hate waiting.  In the meantime I'm gonna talk with my son to see if we can print ABS on his.  Not sure if that means I'd need to install side panels to enclose it.  I'd like to get them printed myself because then it feels more DIY and if we do get it done I can cancel my spot in the queue.

Post by: yotsuya on February 19, 2021, 05:15:23 pm
Sounds like a good plan, Gil.

Almost done with the upgrades. My black PETG came in, time to start printing the Voron Afterburner parts! Since Iím still going to be using this hot end for another month or so, while I wait for parts to come in, there were a few original parts I needed to print to either upgrade, reinforce, or replace because they were cracking. So now my stock hot end has accent color parts!

Bunch of my parts are arriving.  My Misumi black aluminum extrusions are already in.  I have an E3D and a Dragon hot end because I ordered one and then read about the other.  I have 2 different build plate kits on order.  They guys at DigMach took several days to reply and I had already ordered one from China.  But I kinda liked the looks of the DigMach set and it was higher wattage so I'll probably have an extra set if any AZ folks need one.

So much nicer than just screwing directing into the plastic. You use a heated soldering iron to heat the insert, and then push it into the hole. They go in firmly and are snug.

Word of advice. Make sure you ordered the M3x4mmLx5mmOD ones. If you ordered the M3x5mmLx4mmOD ones, they arenít going to work. I speak from experience.

Yeah, Ali and Amazon both list them differently. So if you bought them from Ali, youíre Golden.

Theyíre fun to use. I picked up a special soldering tip to insert them, but you can use a regular clean soldering tip.

Ok, I spent the afternoon replacing the white X carriage parts on my machine. Since the new frame is so dialed in, I felt comfortable printing these high precision parts in PETG.

So now all the parts on the printer match the color theme. Waiting on some wiring to come in so I can install the Voron Afterburner extruder. Good times!

I'm attempting to build one of those Lack table enclosures for my son's printer so he could print ABS for the Voron.  He printed all the parts for it but the table is not tall enough so I've got to figure out how to modify the design.  I had already ordered the plastic before I figured that out so I've got to modify in a way to hopefully still use those pieces.  Thinking it should be a making a wooden square piece to raise the top up more.  His printer uses a bowden drive so it has a stiff wooden tube that loops up over the top along with a wire bundle which makes you need at least 6 more inches above the printer.

Hey Gilrock, what was the determination on the size of the bowden tube required for the Voron 2.4?
I saw the sourcing guide was updated to say that the size depending on your setup, but am still unclear if that means filament size or bowden vs direct drive.
What ID did you end up ordering?
Title: Re: So ... 3d Printers....

Are you guys going Bowden or Direct Drive on your Voron? My friend suggested Direct, as does everything else Iíve seen.

I'm attempting to build one of those Lack table enclosures for my son's printer so he could print ABS for the Voron.  He printed all the parts for it but the table is not tall enough so I've got to figure out how to modify the design.  I had already ordered the plastic before I figured that out so I've got to modify in a way to hopefully still use those pieces.  Thinking it should be a making a wooden square piece to raise the top up more.  His printer uses a bowden drive so it has a stiff wooden tube that loops up over the top along with a wire bundle which makes you need at least 6 more inches above the printer.
I built a Lack enclosure thatís designed a bit taller:

I found the sourcing guide has several mismatches with the BOM spreadsheet you get from the configurator so I've been using the BOM as the master.  It said "PTFE Tube (4mm OD 3mm ID) - 1m" so that's what I ordered and will see how it works out.

I kinda like BadMouths idea of something similar to the V0 enclosure but my son's feed tube and wires currently loop up over the top back rail of the frame.  The Bowden drive is attached exterior to the frame cube so its not inside that cube space for an easy way to contain it.

Direct drive.  The stepper motor was out of stock in the US, so I ended up ordering it from China (from stepperonline).  Only shipping option it gave was DHL.  $20 shipping on an $8 motor.  :cry:
Not even trying to have a budget at this point.  Mostly what's left to order at this point is the hotend and boards.  A long interview with the guy from E3D popped up in my youtube feed and I listened to it while getting ready for work this morning.  Sounds like they are coming out with a new hotend, possibly with copper heatsinks, possibly a replacement for the V6.  I will wait, as my black extrusion won't be here until May and will very likely be the last thing to arrive.

Been dealing with personal stuff and long work hours, but I hope to have Voron parts coming off the mp mini select by this weekend.  I just try to accomplish one thing a day with the one free hour I have.
The Marlin firmware build I had been using became corrupted somehow, so I started over with Visual Studio as Atom is no longer recommended.
As of this morning, the mp mini had the new board installed with a fresh Marlin build and seemed to be working fine.
This evening I will finish my leveling process of printing .3mm tall squares in each corner and measuring them with calipers, then print a new hotend mount out of ABS so it won't sag.
The enclosure gets to and holds at 90 degrees Fahrenheit fairly quickly with only the bed heating it.  Not sure how much higher it will go when left alone for hours.

BadMouth where did you order those extrusions from?  I ordered from Misumi and they got here fairly quick.  They are black anodized.

I ordered the Voron stepper motor kit with all 7 motors from StepperOnline and it was $14.81 shipping.  They got here fairly fast.

Isn't there a model out there that does what you guys want without spending a bunch of time, money, and frustration trying to modify a cheap one?

I am not trying to be critical. I am just curious.

Sure, but theyíll cost you a lot. The fun is in the tinkering, for me. Canít wait to build my Voron.

Letís put it this way - whatís more fun, buying a $100 Pac-Man and restoring it, or dropping $3000 on Barcade Trentís restored one? One will save you time, but cost a lot more. The other is cheaper, and youíll learn a lot from the process. It depends on what youíre looking for.

I looked into a Makerbot, but they have become expensive.  I also felt like it might lock me into their software and filament.

Closest thing to what we are building would be Daedalus. https://www.projectr3d.com/shop/p/daedalus (https://www.projectr3d.com/shop/p/daedalus)
I didn't find out about them until after ordering most of the Voron parts.
Probably couldn't bring myself to spend that much anyway.

I am surprised that I laid out the money for Voron parts, but felt like a cheaper prebuilt printer would nickel and dime me on upgrades then fail to perform anyway.
I am not real comfortable with what I've spent, but hopefully the end result will be worth it.

I still kinda laugh about the fact that most people use them to print figurines.  It reminded me of the King of The Hill episode where Peggy was obsessed with miniatures.  Upon review, it was Hank's mother who was obsessed with miniatures which isn't as funny for some reason.  (sorry Nitrogen_Widget)

I vowed to only print useful stuff, but since getting one I have also started tinkering with cheap 1/16th scale WPL RC trucks.
I couldn't resist the urge to print 1/16th scale coolers/chainsaws, and other accessories for them.  It's easy to scale an STL to whatever size you want.

Yeah the guy uploaded all his STL files but there is nothing showing which piece goes where or how many of each piece you need.  People asked for instructions and he said he had uploaded all the instructions and somehow the site he used to upload deleted his entire description so he said just forget it.  Now its been a couple years and he seemed to have disappeared.  But its one of those things where you probably have nowhere to store it.

I am amazed at how little airflow it takes to warp ABS (at least 5yo ABS of unknown quality).  My heatsink fan was loose and wasn't staying put, but whatever direction it was facing was the place where the ABS warped.  It was pulling air from that direction, but was also throwing a little air to the side of the blades.  I flipped the direction to pull air from the heatsink and couldn't feel any air to the sides, but the part still warped.  Installed the elbow pictured and the warping problem has miraculously stopped.  At least the current part has passed the point where it previously failed.  The highest temp that I can maintain on the bed is 89 and the edges aren't as hot.  That is holding me back from doing full plates of parts.

With the mini back up and running, I decided to try and improve the Mega.  Nearly every print off of it has been disappointing despite spending hours testing and adjusting slicer setting.  It was like it randomly underextruded and overextruded. This evening I installed a V6 heatsink and heatbreak on the spare stock hotend and nozzle.  The difference was immediately noticeable.  The filament flowed smoothly and the first print looked worlds better.  Unfortunately although the mega hotend looks like a V6, the real deal is a half inch shorter so the parts cooler is below the nozzle.  Bought this thing so I'd have a printer to use while messing with other printers.  Now it is also a project.(https://uploads.tapatalk-cdn.com/20210307/bddc8875c1511dbdd4d2c99b3babfc96.jpg)

Getting consistent full plates of ABS parts off the mini now.  The last (I hope) piece of the puzzle was giving the pei sheet a quick wipe of acetone between prints.

Ordered wires for the Voron today and strayed from the BOM a bit.  It calls for 220ft of 24awg silicone wire and the sourcing guide links to a pack of 5 <20ft spools in assorted colors.  Running all those separate strands for the steppers bugs me.  Both because of spaghetti and the rainbow visible through the drag chain.  The four steppers on the z-axis are stationary and the wire they come with is plenty long enough.  I opted for a 50ft roll of 4 conductor black silicone wire instead.  The conductor on one edge is marked and that's all you really need for a stepper motor. Ordered one pack of the stuff in the sourcing guide for limit switches and such.

The BOM only calls for 10ft of the 20awg wire.  I'm assuming it's mostly for power distribution, so ordered a roll of black and red 2 conductor instead of the assortment.  If any of this was the wrong move, I can get wire quickly from Amazon.

Not sure what I'm doing for the drag chain yet.  The cheap stuff I've used on other projects doesn't lay flat.

I have not.  Despite buying this roll of ABS with the printer long ago, this is the first time I've worked with it.  Haven't printed anything but Voron parts and a fan bracket for the Mega.  With this size print bed, I probably won't be printing anything but Voron parts for a few weeks, lol.

I think I have it dialed in except for the bridging.  Bridging is horrendous, but I'd have to learn something other than Cura to speed up or turn on a cooling fan only during bridges.  Could be that I'm only printing at 30mm/sec, but parts are printing while I sleep so might as well use the full 6-8 hours instead of 4.

I need to.  Googled it before, but that's as far as I got.

Still getting some warping on long parts.  The the mating surfaces print face up and those come out level, so the parts are still usable.
I was hoping not to resort to "ABS juice" or hairspray, but might have to. 
Big parts either warp a little where I can get a putty knife under the edge and remove them easily or don't warp and are next to impossible to remove without damage.
Gonna print everything, then reprint the imperfect ones if time and ABS permit.
Some of the skirting on the 350x350 Voron is too big to print on the mini anyway, so going to wait until the Voron is functional and use it to do those large pieces.

I will probably give ABS a try on the Mega this weekend since an all metal hotend has been installed.  The print bed is larger and gets a lot hotter.
The print quality isn't as dialed in and I really don't want to mess with building an enclosure for it though.

Yes.
This was a rush smooth job with no primer for one of my tap handles after I decided to bring hard cider to a party last yr.
just red filament.
Had to blob paint onto it because it wasn't adhering well to the smoothed ABS so that's why it isn't pretty, but I think it worked out.

While the mini is printing black parts, I thought I'd try the red ABS on the Mega.
Don't have any full parts to show for it yet, but this Hatchbox ABS wants a much lower temperature than expected.
Started at 235 and had to step all the way down to 220 before the surface finish on each layer looked correct.
If other colors are the same, an all-metal hotend is not required for this brand.

I question whether it is really ABS, but the test parts I let print halfway seem tough....maybe a bit too flexible for ABS, but tough.
It still warps like ABS.  Gonna buy some hairspray tomorrow.  :afro:

The extruder on my MPMD broke. :'(
so I ordered an all metal one.


got out the other MPMD and a pi zero for octoprint.
the one with the marlin upgrade.
it's printing something out in ABS since I have tpu printed sides to enclose it and 10 amp PSU.
However it's stuttering a little.
noticed baud is 115k instead 256k like my other one.
so i have to look at why i can't connect at the higher speed.

My current problem is that the Mega prints ABS well......except for one layer about a half a centimeter off the bed.   :hissy:
Same layer every time, every part, even with a full plate of parts. Was convinced it was an extrusion problem.
Rebuilt the extruder, relocated the spool, cleaned the leadscrews, loosened and realigned both the leadscrews and guides.
The last thing I can think of is that there is some weird airflow thing happening with the stock hotend fan box (which is 1/2" lower after installing a V6).
This morning I printed a new fan shroud to pull air through and away.  Fingers crossed that it works this evening.

Large Voron parts are warping on the mini, so I may have to break down and try abs juice or print them on the Mega if the bad layer problem can be fixed.

(I've since gone brimless, as breaking off the brims leaves an unsightly white line on the edge.  Sanding doesn't take it off.  Chamfering with an xacto knife leaves a nice edge, but is tedious.)

Yeah, but I can't find anything on the leadscrews that would cause it.  When I watch it happen, it looks like an extrusion issue, but when I feel the filament feeding in, it never slips and the rate doesn't change.  All of a sudden there are strings that seem too high to stick, which lead me to the longshot that maybe the ABS is shrinking downward because of the air from the fanbox.  Maybe that's the level at which the heat from the bed no longer overcomes it.  Longshot I know, but I've tested everything else I could think of.  Experimented with speeds, temperatures(both slight improvement), wall thickness, infill %.

EDIT: It could still be something mechanical, so please share any ideas.  I just visually inspected the leadscrews.  Did not see any wobble or debris.

Just had the thought that I could raise the bed through the adjuster springs and see if the defect stays at the same level on the part or moves down.  If it moves down, that would point to a problem in the z axis hardware.

That's weird how it does it in the same spot.
Are you printing from octoprint or sdcard? if Sdcard try a different card.
Try a different slicer or a different version of the slicer.
Is your Fan turning on at that layer by chance?
I can't think of anything else other than your z screw is tweaked at that height.

The new fan setup seems to have done the trick although I violated the main rule of testing; I changed two variables.
The other thing I did was remove the spring steel PEI sheet.  It was held on with binder clips, not magnets.
It could have been warping, but I don't think the problem layer would have been even across a whole plate of parts if that were the case.
30% into the Voron blower cover and all seems well.  Using hairspray on the Ultrabase.  Hoping it's not that hard to remove when finished.

The other thing I did was remove the spring steel PEI sheet.  It was held on with binder clips, not magnets.
It could have been warping, but I don't think the problem layer would have been even across a whole plate of parts if that were the case.
30% into the Voron blower cover and all seems well.  Using hairspray on the Ultrabase.  Hoping it's not that hard to remove when finished.

Probably the reason my mini can't do ABS. The only fan is heat sink and part cooling. Kill fan and you get heat creep.
Keep fan and and warps.
But since PET-G loves cooling like PLA it works great.

 Metal scraper on a corner, be gentle it will pop up. Some people tear chunks out of their ultrbase  and I just don't know how.
They really have to  be  brutal to do that .
I have the ultra base and even with purple glue stick and still comes off.
Sometimes not easy but you just have to be patient and slowly work it from the corners.

Left it until morning.  Not sure if it was because the ultrabase was cooled, but it felt like it was barely attached when I pulled it off.
First layer wouldn't stick to the ultrabase by itself.  The Aquanet extra super hold made a big difference.

The mini is now printing everything squished shorter than it should be.  So I'm printing some large parts on the Mega with the old mystery ABS that I was using on the mini.
It smells much more like the real thing than the Hatchbox stuff (cough, cough).  20% in and it looks great so far.  I'm actually impressed with the Mega now.  Using brims on these large parts because I've already wasted enough plastic trying to print them on the mini select.

Hey Yotz, what was the deal with your Z axis and how was it resolved?

Doing this upgrade was fun and definitely a learning experience.

The main culprit was the replacement auto bed leveling sensor. The model I got was sensitive to fluctuations in temperature. I did some research and found a better model, swapped it out, then after I took care of that, I had to do some more dialing in and printed some new bed spacers. Once I took care of all that, itís been perfect.

Oh, and that blower cover looks great!

The mega is cranking out good parts steady now.  The only part that gives me trouble are the big z-bases on the right.  They were printed on the mini and warped a bit, but probably still useable.  They warp on the mega too.  It's a big block and fairly dense.

Extrusion won't be here until May, so I tinkered with the 1000mm sticks I bought before.  Chopped it up into a 250mm Voron 1.8 kit...mostly.  Had to use 20x40 on some parts.  Just going to throw leftover parts at it then see where it stands.(https://uploads.tapatalk-cdn.com/20210315/d55720057489cac8479009f5ac033c74.jpg)(https://uploads.tapatalk-cdn.com/20210315/9778945f2a06ddbda48eb84007f99aa7.jpg)

Stimulus money has me throwing money at the Voron BOM just to get it over with.

Bought the expensive Igus chains ($70).  I have generic chains on my 3018cnc which won't lay flat and it bothers me.
Bought an acrylic and laser cut aluminum panel sets from printedsolid.  (chloroplast seems kinda chincy)
Bought a 350x350 PEI spring steel sheet and magnet set not on the standard BOM.
Overpaid for stuff on Amazon just to get it over with.

Currently at $1,611
Still have to buy the SKR boards/drivers and Raspberry Pi.
I may just use the two SKR1.3 boards I have.
So we are coming in around $1,700-1,800.
I could do much better with what I know now, but that is where I'm at.
Probably could have bought a real nice printer already built for that.

The kits on Ali-Express look like a great deal now, even if some parts need to be swapped out for better quality.

I replaced the FEP on my resin printer.
if i just arrange prints around the missing part of polarizer things print fine.
a new screen with glass over the polarizer has been ordered.
but, since i really only print minis on it i can work around it until it needs replacement.

can't wait to see some voron's built and running.

So is the resin worth the hassle?
How about for someone who only occasionally prints mins?

The ABS prints on my enclosed mp mini select were turning out short.
Not sure if it is from the ABS shrinking or the printer losing z-steps.
Outside of the enclosure, the z-axis is accurate.  I think maybe the z axis stepper was overheating.

I installed a .2mm nozzle thinking I would use it for miniature stuff, but haven't printed anything yet.

These weren't worth it.  They curve upward exactly like the cheap generic ones I have.
Maybe it is part of the design I don't understand to keep them from binding.

Either way, when you build a Voron, buy generic and save money to spend elsewhere on the build.

if you are only printing a few it may not be worth it.
you need gloves when handling the resin and emptying the vat.
the resin gets everywhere no matter how hard you try not to drip.
I use mr. clean in a sonic cleaner to get the excess resin off my mini's since it's cheaper than isopropyl and so much easier than shaking them in a container.
then i use an old tooth brush to clean the mr clean off them.
i built a curing station that took me 10 mins. to make.

you need a funnel and a paint filter for when you pour the resin back into the container when a print does fail and you need to clean the vat. there could be bits of plastic are floating in it.
i gotta say it was a HUGE pain in the ass for me when i started using the resin printer but now i have a system and it isn't so bad.

I printed a dozen or so mini's for the Dungeon! board game and they came out ok on my mini with a .2mm nozzle.
not a lot of facial detail but you could tell what what class each mini was for the game.
I see people get better fdm prints and it comes down to how long you want to print for and the scale of the mini.
here is a pic of my .2mm  fdm prints next to my resin prints.
I've seen people get much better fdm prints but they say print time for one mini is 4hrs.
i'm printing tree's in pet-g now on my mini delta and they are coming out good.
I'll still print larger miniatures like giants on FDM also. the quality is good enough for larger models.

I plan to print more mini's though and you can print 5 or 6 mini's in 3hrs or less on resin.
plus they really do look close to injection molded mini's you buy.

ok, for some reason my pic of my minis doesn't want to upload.
i get a security error.
i'll upload later.

jr. extruder just needed oiling.
but had to disassemble the whole thing to do it.
then the ptfe connector gave up the ghost when i went to run a test print.
LOL!

I can't replace the extruder because the proprietary firmware doesn't allow e-step adjusting.
it was their thing.

My buddies and I play it every yr on our lake trip. :)

thingiverse, and as was said myminifactory.
thingiverse has a horrible search engine. google works better.
most models i used for Dungeon! were from the guy who does pocket tactics and there are large collections of mini's with non-descriptive names you have to download and pick through.
shapeways also.
I print the free one's mostly.

I'm looking to start doing skirmish battles with friends.
like the war hammer wars but with warbands instead of armies.
I have a buddy who just got a resin printer also and he's been churning them out.
He's been doing model painting and showed me which air brush and paints to get.

Just ordered the last of the stuff for the Voron.  Total damage $1,828.
I could do much better if doing it again.

My advice: 
Only use the sourcing guide for item reference.

Watch nero3dp's youtube videos before ordering anything.  The sourcing guide is not as set in stone as I thought when ordering.  I ordered the black robot digg rails from the sourcing guide then saw a video where he said not to buy the black rails from robot digg because they were more brittle. The sourcing guide changed later.  I bought an Skr3 board from the sourcing guide and the guide later changed to Skr4.
Join and check the Discord forum (I still haven't).

Place bigger orders at fewer vendors even if the individual part may be more.
If doing it over again, I would have gotten as many of the parts from Powge and TriangleLabs as possible.
For the hardware, I would have ordered 100pc bags from China for any bolts that I needed more than 25 of and tried to cover some of the others with assortment sets.
We are screwing together plastic and aluminum.  It doesn't take grade 8 bolts.

EDIT: I also would have bought generic cable chains instead of the Igus ones.

If doing it over again, I might even just order a kit knowing that I'll have to swap in some better parts.

Now that all the parts printed except for the skirts (which will be printed on the voron), I am circling back around to the main z-drive units which were warped.
Last night I printed one on a 110 degree bed, aquanet hairspray on anycubic ultrabase, draft shield enabled in cura, enclosed printer that stayed around 49-50 degrees.
...still very slight warp on the edges.  For all the other parts, hairspray and the enclosure with the front left open has been good enough.  The problem is that these are big dense chunks of ABS (using 40% infill).
eSun ABS+ came back into stock on amazon and I snagged a roll, so we'll see if that warps next week.

350mmx350mm
All the parts seem little compared to how it looks in pictures.  It will probably only hit the temperatures I am already getting with the Mega inside a foam insulated box.  I am hoping to print 1/16 scale RC bodies in one piece.

I started a 250x250 Voron 1.8ish build using leftovers and parts I already had on hand.  That will be the hot one with a hardened nozzle.  Loosely following nero3dp's hot boi build.

 I don't want to sink any money into that one until the 2.4 is done though.  Gonna start working on sub-assemblies this weekend, but the frame won't be here until May.

Those RC bodies are big enough where you can get some amazing detail with .08mm layer height.
Pet-g would be a good standard filament for those.
since you will most likely be painting them the discoloration from sanding pet-g won't be an issue.

eSun ABS+ came early.  ABS+ part is top, regular ABS part is bottom.  You can see an edge on each where the part lifted as it shrank.  While the ABS+ did lift a little bit less, I am not overly impressed.  The corners still lifted despite taking a chunk out of my ultrabase.  It did not bridge as well as regular ABS.  It was left overnight, was cool when removed, and didn't take much force. While the base stuck, just above the base still shrank resulting in the side curving in like a vase (slightly).  The color is also flat and will not look right mated to shiny ABS parts, so if you're going to use ABS+, use it for everything.

So I'm going back to troubleshooting regular ABS.  I think my infill pattern may be contributing to the problem (tri-hexagon), as long straight runs shrinking are what causes enough force for the corners to lift.  I don't think tabs would help just yet.  The part is useable, but I'd still like to improve my abilities with ABS.

(https://images-na.ssl-images-amazon.com/images/I/71In%2B7SOjJL._AC_SL1500_.jpg)

I use it for ABS prints only and get very little warpage.
however I keep the infill low and increase the shells for most of my prints.

not sure how a 45% infill part would print, but with an enclosure it should keep things from cooling to quickly.

Parts have less warp with gyroid infill, but the surface looks weird like all the shaking from doing the gyroid transfered to the outside. It's only visible under bright light at an angle. Anyways, have just a tiny bit of warp on the corners that probably could be fixed with tabs, but I've wasted enough plastic.  I deemed them good enough.

Started to organize parts and decided the best way to store them until the frame arrives is to go ahead and build sub-assemblies.  Waiting on the frame is actually a good thing, as now I won't rush anything just to get it together.

depending on your slicer adding a top surface skin layer or more top/bottom layers or shells they all use different terms makes them prettier.

after you build the voron, you can reprint them. :)

Sub assemblies went together super easy.  T-nuts are just there to keep the bolts with the assembly.

Probably a dual extruder setup based on the very similarly-shaped thin spots in the red at the top and bottom of both O's, the evenly-colored red whisker at the bottom of the V, and the appearance of the other two black parts with red highlights in the original photo.

Given how consistant the thin spots on the O's are, I really doubt it was any kind of manually controlled process.

You need a plastic pooping robot to get that level of precision.   :lol

EDIT: Here's a closeup of those "thin spots" that happen on the curved parts of the O's and the R where a slicer program might not fill the gap.  Notice that the straight lines of the letters are perfectly straight, even, and filled.  The red straight lines on the right side of the V are also perfectly parallel and evenly spaced with the surrounding black lines.

Yeah its filament.  The guy that shipped me the set was super proud of it.  If you look close enough several of those black parts on the left side have red stripes  on some edges.  I had mixed feelings cause I thought that part looked pretty cool as red and he made it black with the red lettering.  If you look at the PIF Discussion on Discord you can see where I posted the photos and the guy who printed explained how he spent a lot of time with the slicer to get this right.  The photo makes the imperfections stand out worse than they really are.  Those little creases can't even be felt it feels super smooth to the touch.  <queue the That's what she said meme>

Yeah I made the same error.   I got no building done yesterday as planned.  First I couldn't find my package from Bolt Depot.  For some reason my brain was remembering a different box type and shape.  I was going crazy having people help me look and I knew I had only put all deliveries in two places.  On top of a pinball machine and in a crate.  I finally quit and came downstairs later and said well I'm gonna start opening all these  boxes.  Second box I pick up turns out to be a USPS small flat rate box with my bolts sitting on the pinball machine the whole time.  I was like did someone find this and put this here?  They were all like no so I guess I overlooked it the entire time.

Then after seeing your post I look at my bags and 5 of them are silver parts.  I could only find 2 of them in black at Bolt Depot so I went to McMasterCarr and was able to order all but 1 screw type.  Cost a little more because I had to buy lots of 100.  Actually McMasterCarr had that last screw (M3 x 0.8mm x 40mm) but it was $7 for 5 of them and I had bought 30 zinc ones from Bolt Depot for $0.15 apiece.  Bolt Depot only went up to 35mm for that size in black.  I decided I'd rather figure out another way to color those black instead of paying almost $50 to get that one bag of screws.

Started building my Voron frame last night.  Ran into trouble immediately.  The M5 roll in Tnuts I bought from the sourcing list are almost impossible to insert into the MISUMI 2020 rails.  I say almost because I was able to use a screwdriver and bang it with a lot of force to finally get one in.  They slide in from the side just fine but for drop in they are slightly too large.  I ordered a different brand from Amazon so will try those out.  If you build you may want to test them out first because if you know its an issue you could pre-insert them into the rails before you assemble the frame.  I really feel they should be telling folks to do that anyways.

Well learning mistake #2.  I was opening up one of the linear rails from the plastic and I cut along side it so I could pull it out from the wrapping.  But when I went to pull it out the square platform that rolls along the rail snagged on the plastic so the rail pulled out leaving the platform still in the plastic.  It didn't look like a big deal but when I pulled the platform out to look at it all these tiny 1mm bearings fell out into the rug and I'm like WTF.  Took me 30 minutes to fix it.  I used magnets to try to find all the bearings and then inserted them into the slots which they don't hold into very well.  Then as I'm trying to push the rail back in the bearings kept wanting to pop out.  I finally got it though.  Lesson learned do not let that platform come off the end of the rail.  There are rubber inserts on each end to prevent it but that popped right off when I pulled the rail out of the plastic.

Then I began to install the rails and I had the same issue with the M3 roll in T-nuts not fitting into the MISUMI 2020 frame.  I thought I had tested the M3's and saw it working but guess not.  I hadn't ordered any replacements for those.  I did some searching and found several folks complaining in the comments for the T-nuts on aliexpress where the sourcing guide leads you to buy that these are too big for the MISUMI frame.  I also searched and found many folks on Discord having t-nut issues for the Voron.  I finally said screw it and ordered the expensive ones from MISUMI.  Now my damn t-nuts are going to be 10% of the build cost.

FYI, you are supposed to degrease and regrease the bearings before install.

No.  I wish Nero 3dp had more of these shorter videos to cover the entire build. 
Other good information is there on his channel, but buried in 3.5 hour livestreams that I don't have time to sift through.
Occasionally I will play one in the background while doing other things and pick up useful things.

I bet most of them are still usable. 

Looking at them, the power inlet panel is for the separate switch and filtered inlet option.
Did you buy the filtered power inlet, or the regular inlet/switch combo we all use on arcade machines?
(you might need to clarify with him which one you need)

I bought the regular unfiltered one, but am thinking that the center of the back of the machine isn't the most convenient location for the power switch so I may move the switch to the back corner.

EDIT: If you bought everything on the sourcing guide around the same time I did, you probably have both.  ;)

Thanks for catching that I didn't even notice.  I'm not even sure the one I bought would fit either one I was going to have to wait and see.  I do not believe I bought both because by the time I got to those parts I was following the BOM and only using the sourcing guide to find where to buy.  I remember being quite confused by what they wanted me to get for the power inlet.  I ended up buying this one and figuring I might need to design and print my own part.  I liked this one because it fit my black/red theme.

Looks like the standard size mounting hole so I think you'll be ok...provided they print the piece for the non-filtered inlet. 
I think they switched away from the filtered inlet somewhere in the revisions on the way to 2.4, but the STL files still have both options.

I put together the carriage and extruder this morning.  No word on the rails which aren't supposed to ship until 5/5.

Yeah.  When I ordered the lead time for black pre-drilled/cut extrusion was that far out.  Last time I checked, the product page showed 4/15.  I tried the online chat to see if I could get my order moved up, but the customer service person didn't respond to the question.  I could have had it right away if I'd bought silver/clearcoat. 

I had some silver extrusion on hand, but did not trust myself to cut any pieces longer than my table saw sled allows.  I ended up chopping those up into a smaller voron 1.8 frame.  Haven't printed any parts for that yet.  It will be more about using leftover parts and what I have on hand rather than strictly following the plan like I am doing with the 2.4.
Title: Re: So ... 3d Printers....
Post by: Gilrock on April 03, 2021, 01:45:01 pm
Yeah I ordered black predrilled cut extrusions as well and I believe I ordered after you did.  It shipped within a week.  Only difference might be I ordered for 300mm frame but I can't see that being the reason.
Title: Re: So ... 3d Printers....
Post by: BadMouth on April 05, 2021, 07:31:16 am
When I started on the Voron project, I didn't realize that the printhead assembly that holds the hotend and cooling duct can be swapped out fairly easily.
It's just a matter of backing out two bolts to flip the fan up, two bolts to free the printhead, and disconnecting two wiring connectors.

The V6 on the monoprice mini select was having underextrusion issues with PLA.
After some testing and research I believe that the PLA is sticking to the inside of the stock V6 heat break when retracted far enough to pull melted plastic up that far.
The extruder on the mini isn't good enough to overcome the resistance.  If I give the plastic a pull and a push things start flowing again. 
I reduced retraction to 2mm.  The problem went away, but now I have stringing.

So I ordered some ptfe lined heatbreaks.  Also ordered one with a 4.1mm bore that allows the bowden tube to be all the way against the nozzle itself, but have to wait for that one to get here from China.

Where this pertains to the Voron having swappable printheads is that I now plan to make a separate printhead for PLA and maybe a third with a larger nozzle.
Heater cartridge and thermistor will need to be the same type on each since those are set in the firmware.

For anyone planning a future build, it will require two more M3x40 and two more M3x16 cap head bolts per printhead (in addition to the extra hotend/thermistor/heater).
The V6 clone from Trianglelab makes it fairly cheap to add an extra printhead.

Hey Gilrock, got a tip for you.

I degreased and regreased my robotdigg linear rails this evening.
They seemed fine out of the package, but I am trying to follow the Voron way to the letter.
They didn't seem any better and maybe a bit worse afterward.  There were spots they bogged down or hung up slightly.
After trial and error and close inspection I discovered small spots in the channels the bearings ride in (on the rail) that didn't look like anything more than grease.
Those were the points where the carriage was sticking though.

After clearing the channels until absolutely nothing was visible the carriages fall freely from one end to the other.
I cleaned them by pushing the carriage to one side and then wiping the channel with my fingernail covered by a paper towel.  Always away from the carriage and always all the way past the end.
Repeat for the opposite direction.  Not sure if I was just clearing excess grease or there was tiny tiny debris mixed in, but I feel a lot better about the performance of the rails now.

Well I didn't talk about it but dude I already disassembled, degreased and re-greased 8 rails last Saturday.  It was 5-6 hours work.

This was the difference.
I had forgotten but the longest lead time was on the uprights which are 530mm on the 350x350.  I'm guessing Misumi didn't have any 1000mm in stock to cut to length, but did have 500mm (or at least expected it in in stock sooner).  The lead time on the HFSB5-2020-530-LCP-RCP uprights is now June.  Hopefully I still get mine early May.

The Mega has been doing a pretty good job cranking out ABS parts, so I went ahead and printed the rest of the parts including the skirts.
There isn't much more that I can assemble without the frame. 
It has been nice to work on it without there being any rush.

I may try to go ahead and set up the software which is going to be my least favorite part.

Yeah I received my re-printed Voron Print It Forward parts.  He didn't do the dual-color thing on the reprint.  I also received the MISUMI roll-in t-nuts and they actually work after the previous 2 orders failing to fit.  I wasted so much money on t-nuts.  And I got my IGUS chains.  That was an ordeal to order.  First IGUS emails and says they don't have what I want in stock but they have an alternative that bends the opposite way.  I said no I either want everything I've ordered or a refund.  Then they email that they can backorder the items if I want so I respond how long would a backorder take.  They email back and said 4-5 weeks.  I replied that is fine and then the darn order shows up in less than 2 weeks.  I've had too many other things going on to continue the build yet.  Part of the problem is I really have nothing I want to print when its done I just wanted to build one...lol.

I haven't tested my T-nuts yet.  Just loaded up a cart at Misumi and by the time shipping is added it will be over $100.   :o

Tried the roll in T-nuts.  The M5 are fine, but the M3 have no chance of working properly.  Both are from "Change da Store" on Ali Express.  The M5 have more of a triangular shape that does not have any clearance problems.   I had some M4 ones from Polis3D on Amazon from a different project.  They are also the triangular kind.  Ordered a 100pc bag of M3 from there hoping they will be the same design.  At least I can return those if they do not fit.  I will still preload as many of the fat ones as I can think to.  Thank you for the heads up.(https://uploads.tapatalk-cdn.com/20210414/f6d8f7d9cf9db529f75db5a403fa783d.jpg)

Post by: Gilrock on April 14, 2021, 09:15:14 am
That's what's weird I also ordered all my original t-nuts from "Chang da Store" and neither my M5 or M3 would fit.  I saw others in Discord saying they had the same experience as you where M5 would fit.  It would be nice if the instructions would just tell us how many to preload in each rail section.  Funny I don't mind spending the $100 for t-nuts to a save some frustration but I get pissed when Digikey splits up my order into 4 different deliveries charging me shipping on every one.  I got a package yesterday that had pins that cost 44 cents and charged me $7 shipping.  I didn't even notice they had been backordered.  Not sure if I missed it but if they have an option to not split up the deliveries it could save you some shipping but there was like a month difference between my first and last delivery from them.

Spent half the night compiling Marlin firmware for my Sovol Printer. This is my first time compiling more than some simple arduino script, so I am pretty pleased with myself. I have been getting into modding my printer quite a bit, and that includes putting in a new BTT SKR board, which is not really designed for the Sovol. I was using someone else's firmware when I realized that the hotend fan was not turning on. Kinda a problem, so the only solution was to roll my own.

Anyway, I'll share pics of where I am at with my printer in a few weeks. I need sleep. For tonight, I'll share the custom boot screen I made. I gave her a stripper name.  ;D

Post by: BadMouth on April 18, 2021, 11:23:43 am
Boot screen looks awesome Vigo!

I went through the Marlin thing when compiling it for my monoprice mini select.  Make backups of your files including bin files.  At some point my build went to crap and I had to start over.  It went pretty quick the second time around though.  I was hoping the Voron build would be plug and play on the software side, but looking ahead I think it is going to be another huge learning curve time sink.

After I finished printing ABS Voron parts on the Mega Ss, I needed something with a cooling fan to start printing PLA again.  So I got this setup off thingiverse.  Pretty happy with it although I still can't seem to get this thing dialed in as well as the mini was.

Thanks, BadMouth! Yeah, I will keep a backup as soon as I can confirm the settings are all good. I have a hunch I might need a few tweaks because I was shooting at the hip on a couple of the settings.

Hope for your sake the Voron is pretty plug and play, but after watching you guys hash out your builds, I am getting the impression you are going to finish up with the technical knowledge to start your own line of 3d Printers. I'd back your kickstarter.  :lol

for starters, when you get it you will wonder "huh?" because it's actually some kind of network device.
you need to take the case apart to get to rock64.

recallbox runs on it pretty good.
armbian does also.
they have the video drivers.

dietpi does not.
most of the OS images out in the wild are a yr old because this card has been out for almost 5yrs and the pro version is what people are mostly supporting.
it appears to be roughly the same speed as an RPI3 (not the b).

the lack of current support for this board made me decide to just toss diet-pi on it and go with octoprint.
the diet pi distro has A LOT of software designed to make this an appliance.

For those of you with those flexible magnetic beds, are the bases that adhere to the printer plate pretty thin and heat conductive? I am considering getting one, but I have a few glass beds I swap in depending on print need, and don't want to lose use of that. I also saw a person just not adhering it to their bed, just clipped in, is that feasible?

I am considering getting one, but I have a few glass beds I swap in depending on print need, and don't want to lose use of that. I also saw a person just not adhering it to their bed, just clipped in, is that feasible?

My experience is very limited, but here it is.
I installed it normally on an anycubic mega s.  It took the shape of the heated bed, which was not flat enough to suit me.
It had high spots and low spots to where I could not find a happy medium.  This was not the fault of the flexible plate as it was just conforming to the heated bed underneath.
The first order of business would be to figure out if the plate the magnetic sheet adheres to is flat or warps when heated.

So I removed the magnet and adhesive which was a PITA.  Left without a magnet, I tried clipping the flexible sheet to a glass bed.
It worked, but the thin sheet would warp very slightly when heated.
Not sure how much trouble it was causing, but this is not the way to go.

In retrospect, I think the best solution for that particular setup (where the underlying bed is not flat) would have been to adhere the magnetic sheet to a piece of glass. 
Even though it's more material for the heat to get through, at least it would be flat.  I have not spent the money on another magnetic sheet to try it.

I still think a PEI coated spring steel sheet is the way to go and have already purchased one for my Voron build. (frame finally supposed to ship tomorrow)
The machined heated bed is flat on that though, so I don't anticipate any of the problems I had on the Mega.

The ultrabase on the Mega has worked well, especially when sprayed with aquanet hairspray.  For the ABS parts I printed, it sucked having to wait for the bed to cool enough for the parts to release (20-30min).  Then I had to wait for the bed to heat back up to 100 degrees before the next part would start printing.  With a flexible sheet, I could have kept the printer warm and running.

I appreciate the full response.  :cheers:  Didn't think about warping. It wouldn't take much to create a whole new issue. I think I will stick with my current setup for now, until I feel everything else is dialed in. One less variable to worry about.

Ok I've got a new question for the peanut gallery.....   Has anyone tried polysmooth?    I ran across it the other day.   Supposedly it's a pla but when you put it in an enclosed space and spray it with alcohol it melts and smooths the print similar to how abs melts with acetone.

i've never heard of this stuff.
youtube has.
this guy has a chamber to put the model in.

looks straight out of sci-fi.

I've been waiting for someone to test fans like this:
https://youtu.be/lcJyFUcGg8U

results (https://docs.google.com/spreadsheets/d/1jV-VOd-L0NSTz7ruDRIOj3mM9WI9cRUXQDgIiIQensg/edit#gid=0)

Oddly enough, this came out just after I installed a Winsinn fan on the Mega.
All seemed well until this weekend when it was 80 degrees in the house instead of 65.
It kept under-extruding part way into each print.  When it did it sooner in the print on each consecutive attempt, I figured it was heat creep.
Back to the original fan (with a non-original toolhead and hotend) and things are working fine again.
The V6 heatsink felt cool to the touch, but I guess internally the heat was creeping up too far.
EDIT: After swapping fans and it working correctly again, I also removed the silicone sock since it was basically creating a seal between the heater block and bottom of the heatsink.

I also bought Winsinn fans for the Voron based on the sourcing guide.
Guess I'll tack another new fan onto the build cost.
Misumi extrusion was supposed to ship today and did not. 
If it doesn't ship tomorrow I am going to call and see about just getting clear anodized extrusion if black is going to take much longer.

EDIT: Misumi extrusion shipped on time and arrived in two days.  Anxious to get started, but have other obligations.  Preloaded some t-nuts and arranged the parts.  Hopefully will assemble frame tomorrow, but rest will wait until next week.

Frame and motion systems done.  Belts installed, but not trimmed.  Installed heating element and magnetic sheet on build plate, but it is not bolted down yet.

At first I was upset that the magnet and spring steel sheet didn't cover the entire build plate, then I realized that is was not undersized, the build plate is oversized (14").

The aluminum composite panels are worth the price.  I was afraid they'd just be cheap foamboard with super thin aluminum on the surface.  The aluminum is pretty thick and the surface finish is perfect.  The silver edges where it was cut bothered me so I hit them with a paint pen.

Not sure how fast wiring and software will go, as I don't enjoy those things as much as building.(https://uploads.tapatalk-cdn.com/20210509/d3a914bf2c47a41fb40237f84781e268.jpg)

For anyone who missed Marsupial's  Build your own HID-mouse compatible spinner (http://forum.arcadecontrols.com/index.php/topic,165028.0.html) project, here are two parametric mounts created in OpenSCAD.

(http://forum.arcadecontrols.com/index.php?action=dlattach;topic=164992.0;attach=387890;image)

The first one has a chamfered bezel.
- The OpenSCAD code generates a model with both the nut and the mount.
- The .zip files linked below reorient the mount so it is print-ready. (i.e. face down)
- Be sure to download the .zip files for both the desired mount and the nut.  The mount .zip files do not include the nut.

Installation instructions:
1. Drill a 2"/50mm hole in your 3/4" thick (or less) control panel.

2. Fasten the mount to the CP using the nut.
- Keep in mind that it is very easy to cross-thread if the nut isn't kept level.
- Use the "turn the nut backward until you hear a click then turn it forward" trick to avoid cross-threading.

(http://forum.arcadecontrols.com/index.php?action=dlattach;topic=164992.0;attach=387891;image)

3. Fasten the encoder to the mount using M3-0.5 x 8mm screws.

Finally wrapped up the wiring on the Voron (hopefully).
Observations:

I flipped the main power supply so the mains voltage is toward the center.  If arranged like in the manual, a finger stuck through the holes in the skirting could touch 110v.

I don't like the Molex microfit connectors and would not use them again.  The plastic housings are ok, but for some reason neither the hotend or part cooling fan would work when testing with a battery.  Something was wrong with the connector on the fan side, so I redid it.  Second attempt didn't fare any better.  Not sure if I was breaking the wires on the crimp or what.  Switch to JST SYP connectors and had no issues.   Hoping it was just the tiny fan wires since everything else including the hotend is still using the Molex connectors.  It is a PITA to get the pins to slide into the housings when using silicone wire....like trying to push the pin with a wet noodle.

Per the wiring diagram power is supplied to the Raspberry Pi via GPIO pins.  There is a warning that this involves some risk, but you are "unlikely" to have a problem.  I hacked a charging cable and used the actual power input.  They should just add a USB C charging pigtail to the BOM.

After laying out the wire, I decided to go with all black and red wiring on the top side.  The black 4 conductor ribbon cable really shined here.  I had several runs of it, but it was easy to tell what was what with a multimeter.  Limit switches were wired NC.  Inductive sensor had one wire removed, so only 3 conductors on that one.  With the steppers, you only really need one conductor referenced then the rest of the ribbon can be placed in order.  Only downside was trying to push pins into Molex Microfit connectors with the super soft silicone wire.  The JST connectors on the PCB end weren't nearly as difficult.

I flipped the connectors on the LCD, but the wiring would have worked out a bit better if I had flipped them on the SKR board instead.

Haven't set up software or powered it up yet.  Not sure if firmware should have been set up before making all these connections, but that is a project for another day.

I've gone back a few pages and I'm not seeing anything about it, so I feel safe to ask how you were able to mount those components on what appears to be the bottom of this? I'm not seeing obvious connections for some rail-mounting system, so I'm suspecting magnets. Thinking this could be an effective way to mount items inside an MDF cabinet.

Yeah mounting that power supply in an enclosed place like that makes me nervous, especially considering one of mine had a meltdown in the past.   I mean it should be fine but you never know.

The boards, PI, power supplies, etc. are all mounted to those two silver DIN rails.  And those DIN rails mount to the black 2020 aluminum extrusion rails that you can see at the bottom in the second photo.

...are all mounted to those two silver DIN rails.

Thanks for the info. Apologies if there is a better place to ask this. How are the components (PCBs etc.) attached to the DIN rail?

It uses spring loaded clips.  If you push the item to one side to compress the spring, the opposite side of the clip is given enough clearance to be lifted off the rail.
The clip on the solid state relay is metal and was purchased.  The clips for the rest of the items were 3D printed. 
The rails I received were kind of thin, so I had to add a piece of duct tape so the clips fit tight enough to prevent sliding.

Here is a youtube video that came up in my feed recently, but I haven't watched it.  Looks like it provides the info you are looking for:

Installed software on the Voron today.  It wasn't that bad, but I was annoyed by having to install and learn a bunch of tools that weren't already in my wheelhouse.  If you are already familiar with Pi and networking tools to manipulate files on the Pi then it will go very quickly.

I completed all the various calibrations and tunings without incident until the last friggin' one.  All that was left to do was calculate e-steps, probably the easiest thing.  Extruder makes a grinding noise, but does not move filament.  Turning the big gear with my finger moves filament.  Probably something stupid like the grub screw on the motor....

Done for today.  Next time it should be laying down plastic.

Gil, how is your build going? (or how did it go if already completed)

I got all the parts now I've lost interest in building it.

go ahead and send them to me, I'll build it :)

Got the Voron far enough along to melt some plastic.
The problem with the extruder turned out to be the wiring.  I had the wiring wrong on the extruder end, then after correcting it still didn't work because one of the wires had broken at the molex microfit crimp.  Got that fixed and it worked, but filament moved in the wrong direction.  Reversing in printer.cfg didn't work, so I had to rewire yet again.  Same thing happened to Nero3dp on his most recent build, so it wasn't just me. 

It works now except that it doesn't save my z offset.  I will work on that tomorrow.  First print was crap because I had to adjust the z offset on the fly, so I cranked it up to 200% speed.  It was already at a fast draft of 120mm/sec so I guess it was running at 240mm/sec.   Cube looks horrible, but seems dimensionally accurate. I will install the sides and tune tomorrow.

With Mainsail and Klipper, the LCD is kind of pointless.  It displays temps, but the navigation knob doesn't do anything and the button only functions as an emergency stop.  You cannot tune anything on the fly with it.  Everything needs to be done via the web interface.   With Octoprint the LCD would have some functionality.(https://uploads.tapatalk-cdn.com/20210619/ae7b40bbdc69f96fe1e2296a8574eeb9.jpg)

Finished building the Voron completely with the exception of the interior exhaust grill which I thought I printed, but can't seem to find.
Did some more calibration and setup.

Clicked the update button on Klipper and now nothing works.  :banghead:
I believe I have to redo the firmware for the SKR boards which means I have to move the machine (which is harder now that the plexi is installed), remove the bottom panel, & remove the SD cards from them.

Dealing with crap like this is what I was hoping to avoid by following someone else's plans.  :angry:


EDIT: and now one of the Z stepper motors seems to have taken a dump.  Odd that it would coincide with the software thing, but I swapped leads on the stepper motors around and they all work fine on any output except this one. This is a horrible hobby.

Meh.  Redid the firmware on the SKR boards and they seem to work as before.
Stepper motor turned out to be a wire that broke at the crimp.  Seems to be a theme with me.
Back on track and half a day behind where I wanted to be.

Title: Re: So ... 3d Printers....
Post by: BadMouth on June 29, 2021, 07:08:33 pm
...so this happened.  There didn't seem to be any clearance issues when calibrating or doing test prints.  The only thing I can speculate is that this side tweaked from me pushing the ptfe tube back into the toolhead and made the screw heads angle out. The printer self leveling would auto-correct for any height problems.  The clearance is only as much as the weatherstripping is thick.

Huh?  It's a low res pic.  The layer lines are pretty smooth, but are also camouflaged by some vertical artifacts going on.  Not sure if the belts need retightened already or if it has something to do with seeing through the clear petg.

I bought an accelerometer to tune for resonances, but got tired of working on the thing and having never printed anything on it.

First large format print complete (clear petg).  Not as oem looking as the design in my head, but it got done.  I did concentric infill at just under 100% hoping it would come out clearer.  It isn't clear, but it's solid as a rock.  Someday I'll graduate from Tinkercad to Fusion.

So my understanding is the best you are going to get out of clear filament is sort of opaque frosted and the way you do that is with a lot of sanding and polishing.

I was putting away some spools of filament this morning and thought I would share my storage method.

   It requires a vacuum sealer.  11" rolls for the vacuum sealer are just large enough for a 1kg filament spool to squeeze into.  The trick is to make the bag extra long so that instead of making a new bag every time the filament is stored, you can just trim off the end and reseal the same bag.

   Toss a dessicant packet in and vacuum seal.  The vacuum is strong enough to deform the spool, so hit the seal button just before the spool is pulled against the vacuum sealer.

From there I put the spool back in the original box it came in, which is much easier to stack or place upright on a shelf.

Nice.   ;D

Turns out that most filament spools *just barely* fit into a 1 gallon ziplock bag if you turn the bag diagonal so the top corners of the bag align with the edges of the spool.

A small (2" diameter) analog hygrometer (humidity meter) like this one (https://www.amazon.com/gp/product/B01DEN4UYG/) is an easy way to see how well your desiccant is -- or isn't -- working.
- It fits inside the hub of most spools.

(https://images-na.ssl-images-amazon.com/images/I/51mKTkrQpkL._AC_.jpg)

For desiccant, I like to use two of these (https://www.amazon.com/dp/B00BL79JDK) small (2" x 1" x 1/2") 10 gram aluminum canisters per spool.
*** Avoid the old, toxic Cobalt Chloride canisters with blue beads. ***
- They fit inside the hub of most spools.
- When the beads turn from orange to dark green, put the canister in the oven for 2 hours @ 250 degrees. (F)
- The only downside is that the top and bottom halves of the canister are not solidly connected.
-- You can easily mod them by drilling out the corner vent holes and using 0.020" lock wire/safety wire.
- The 40 gram versions are more sturdy but are overkill.

thought it was pretty sweet for a few months.
until i knocked it off the bench.  :banghead:

does anyone else keep an assortment of hardware for assembling projects?

Been there! Those shelfs go down with a huge mess. :banghead:


I'm not about to suggest my small parts solution is great, but I have been working on this same problem. The issue I have is I bought so many of those tiny amazon boxes with assorted lengths of M screws, I would be wasting a lot of plano cases to keep them compartmentalized, so I just got a small tote to hold all my metric stuff and I keep them in their Amazon boxes.

(https://images-na.ssl-images-amazon.com/images/I/611BxxrmSLS._AC_SL1500_.jpg)

Other things like extruder parts, nozzles, springs, etc, I keep in those metric zip baggies and label the bag. I have a ton of them that I use for board game organization. The only thing left for me to do is print some partitions in the tote to separate out the baggies.

I use a variety of storage systems.

- A wall-mounted parts bin similar to this one from one of the big-box hardware stores.
(https://mobileimages.lowes.com/productimages/438472bb-2ad6-4066-aa85-0d0836f8eb53/15277377.jpg?size=xl)

- A bunch of the Harbor Freight 24 compartment (https://www.harborfreight.com/tool-storage-organization/parts-storage/24-divider-storage-container-94458.html) tackleboxes that are OK for medium parts, but the divider system is . . . less than stellar . . . for very small parts.
(https://shop.harborfreight.com/media/catalog/product/cache/1/image/265x/9df78eab33525d08d6e5fb8d27136e95/9/4/94458_W3.jpg)

- For small parts like connector pins that would be a total pain to sort through, consider the Harbor Freight 25 box storage system (https://www.harborfreight.com/tool-storage-organization/parts-storage/24-container-storage-box-90243.html).  The 25 small boxes have snap-lock lids.
(https://shop.harborfreight.com/media/catalog/product/cache/1/image/265x/9df78eab33525d08d6e5fb8d27136e95/9/0/90243_I.jpg)

I'm thinking now a bunch of these might work for me.
Those are better for keeping small parts separate than the 24 compartment one, but are a bit more expensive and not as flexible.  YMMV.

I started accumulating extra nozzles, heatbreaks, etc and wanted a toolbox to keep it all in.

I ended up getting a very small Plano tacklebox with removable clear trays.
https://smile.amazon.com/gp/product/B000OES590/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 (https://smile.amazon.com/gp/product/B000OES590/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1)
It's ok, but anything too big to fit in a tray ends up in the big top compartment.  A bigger one might work out better.
It is smaller than it looks in the pictures.

The one thing that I have been happy with was this plastic storage box with individual compartment lids:
https://smile.amazon.com/gp/product/B089M45T8N/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 (https://smile.amazon.com/gp/product/B089M45T8N/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1)
You can get them cheaper from China if you are willing to wait for delivery.

For the small screws used in building stuff, I'm with Vigo.  Just buy the assortment packs that come with a case.
When building the Voron I ordered exactly what was needed from Bolt Depot, but I would not do it that way again.
You are much better off buying cheap assorted sets.  Attaching plastic to aluminum does not require grade 8 bolts.

EDIT: I also have 3 of these that random leftover bolts and screws go into.  It feels like more work than you would think to move them on top the workbench, unclip both sides, fold down the front, & pull out the tray to get at the parts.

Anyone have a system for remote access/monitoring that they would like to share?
I read somewhere that an alarming number of Octoprint installations are open to someone else on the internet accessing them.

I am using Mainsail/Klipper on the Voron, but it is only accessible via  local network.
I set up an old security camera (on a guest network) to monitor prints, but cannot do anything if there is a problem.
I considered using a smart plug that could be turned off remotely, but in some situations it would be better to pause the print.

I will be taking round 2 at setting mine up soon. I put in a pi and a touchscreen in on my printer as part of the control panel. My first attempt at putting octoprint on it failed, then I lost interest to keep pushing it.

Post by: BadMouth on July 13, 2021, 02:26:59 pm
I am envious of that power switch on the front (instead of the center of the back like the Voron). 
Keep us updated on Octoprint.  It annoys me that Klipper doesn't use the click wheel for anything and only uses the button as an emergency stop.
I may give octoprint a shot.

My latest idea for remote pause is to wire something as a filament runout sensor. 
The old security camera I'm using can pan, so I could even use it to hit the switch.  :lol

I finally started assembling my Voron.  It started with major frustration because I needed the 1mm shim washers and could not find that order anywhere.  I wasted 2 hours looking Saturday afternoon and gave up.  Then Sun morning decided I would clean up the side room that had tons of junk stacked around as one last chance.  I cleaned and stacked all my stuff on the shelving on one side and then told my wife it was her turn to clean up her sewing table area that looked like a tornado of material hit it.  Well of course she finds the box with my parts buried on her table but accuses me of putting it there.  I was like the last spot I had that box was on my pinball machine and you cleaned that off.  Its a major argument every time I can't find something...lol.  I'm like just don't move my stuff ask me to move it and then I won't have that variable in my head.

Then I started with the Z drive assemblies.  First off the gear would not fit onto the motor shaft the way they showed in the manual.  I could put it on with the fat side first but then it would stop near the end like it was tapered.  It wasn't until I tried all 4 gears that I found 1 of the 4 would freely fit all the way up and down the shaft so I had to use a drill to get the other 3 to fit.  I figure when they anodized the parts black it messed up the fit.  Then I got to the motor brackets and could not find the parts anywhere.  The part shown in the manual and the Nero video both showed a complete circle part attaching to the motor.  I finally found another video where the guy talked about the issues in the manual and he showed how they had changed the part so that it only has 3 screws and part of the circle is cut away.

I am impressed with the quality of the design so far.  The way they have the arm you swing in to tension the belt is pretty awesome.
Title: Re: So ... 3d Printers....
Post by: BadMouth on July 26, 2021, 10:45:42 pm
Weird about the z motor brackets.  I must have had the old stl files because my parts matched the manual.  I did go back and download newer stl files when the limit switches didn't fit right and I found a change submitted that referred to the issue.

One issue that I may be able to steer you right on.  When you attach the motors to the A/B drives on the gantry, rotate them so the wiring exits face each other.  I had the wires coming out the back, but then there was so little clearance that the wiring was going to rub against the back panel as the gantry moves up and down.  It wasn't a huge deal, but I did have to unscrew and rotate them in place with the belts already ran.


Enjoy.

Started throwing a Voron 1.8 together from leftover parts and the extrusion I had cut while waiting on the 2.4 frame.  Had to use 2040 for some parts of the frame.  Might have to swap in two more pieces to free up 2020 for the bed.  This will start out as a test rig to experiment without screwing up the 2.4.  I spent money on rails and some 40mm bolts, but that is about it so far. Gonna run the crappy belts I already have for now.  Nickle and diming my way to a z axis.

Got some carbon fiber polycarbonate on the way.  Looking forward to testing its strength.

Polycarbonate I ordered wasn't carbon fiber.  I was actually kinda relieved as this meant I didn't have to swap hotends for fear of scratching up the copper heatbreak of the dragon.

Anyways, if you've done ABS, have no fear of polycarbonate (at least Polymax by polymaker).  Spool went straight from the package to a filament drier feeding the printer. Printed on PEI with a coat of aquanet.  Hotend at 270, bed at 110, no fan.  Chamber stays around 50.  Very, very slight warping.  Less warping than the same part printed in ABS. Then I cleaned the PEI and recoated with Magigoo PC.  No warping at all.  Been printing parts for two days.  The only thing that failed was a small part where my 15 second minimum layer time wasn't enough to let the layers solidify.  Reprinted with one small part on each corner of the bed and they turned out proper.

So if you can do those temps, give PC a try.  Stronger and more heat resistant than ABS, but no more hassle IMO as long as it is kept dry.  If it does sit around soaking up moisture, it will need baked for 8 hours per the instructions.  Mine is going right back into a vacuum bag when I run out if things to print.

Wife wants me to get a 3D printer, Wants to print off a bunch of Disney related stuffs.  What is the current recommendation for less then £200 in the UK?   Needs to be simple to setup, simple to use, and I think most of the stuff she wants to print is in the 3 to 4 inch range.  Was looking at the Creality Ender 3 Pro with tempered glass.

I bought an Anycubic Mega S thinking that the Prusa knockoff design would be superior to the Ender.  Upgrades like a different print surface were a PITA to find in the correct size though.  The extruder sucks, but I'd have to switch to custom firmware to upgrade it.  I wish I'd just bought an Ender because they have become the standard.  You will never not be able to get a replacement part or have a problem that someone hasn't already posted the solution to.  I don't see a reason to buy anything else in that price range.

If anyone out there is considering Klipper and debating Mainsail vs Fluidd for the pi:

Everything I found when searching the subject said they were pretty much the same and decide for yourself, so I went with Mainsail.
Added a pi cam to my test build.  It was fairly plug and play, but the results were less like video and more like a picture updated every so often.
It wasn't anywhere near the 15fps set.  Later, an update killed something in my Mainsail install and I could no longer connect, so I gave Fluidd a try.

They are extremely similar in appearance and function, but the pi cam works better in Fluidd and the control panel panes can be rearranged. 
It also reports information on the pi and warns when the pi is being throttled.
At this point in time, Fluidd is superior IMO.  I like it well enough that this evening's project is to switch the 2.4 over to Fluidd.

I also planned to use the test rig to experiment with physical buttons in Klipper.  There wasn't much experimenting as it turned out to be stupid easy.
It's odd that I couldn't find many online tutorials covering it and those that do exist complicate it by using pins on the pi or a secondary mcu.
A few lines in the config file is all it takes to use buttons wired to the extra endstop pins on the SKR board to send any gcode command or macro. 
I only have 2 inputs available on the 1.8, but have 9 on the 2.4 since it has 2 boards.

if anyone is interested.

anycubic photon s resin printer is $99 shipped right now.

not mono or that big, but i ordered one for my kid.
he keeps bugging me to make cartridge stands for his n64 on mine so i figure this is a good time to introduce him to 3d printing so he can make his own.
he's 15 so i think he's old enough.

oh, and happy turkey day.

Did a fair amount of tinkering with the printers last week.  Moved them to the basement & vented the V2.4 to the exterior of the house.
Added lights & a cheap Arducam to the 1.8.  Very happy with both.
Made a double sided spring steel bed with PEI on one side and Garolite(for vinyl) on the other.
Spent a couple hours brute forcing the correct syntax to get chamber temps displayed on the LCD.  :-[

In previous testing, chamber temps only got up to 50įC.  When actually printing, they kept climbing and climbing.  Eventually it touched 70į, but averages closer to 66į.
I am glad it didn't get any hotter.  I originally wanted to build a 100į chamber, but after digging into the research realized that the plastic races in the linear rail guides are only rated to 80į.
I found that preheating to 55-60į with a heat gun gets the chamber temp up a lot faster than waiting on the bed to heat it.  Also the aluminum extrusions act as a heatsink, so any future custom printer is going to have an interior frame completely insulated from the outside world.

Also dealt with chamber temps on the V2, as the exhaust fan was pulling air out.  I came to the conclusion that it is better off sealed with some type of fume mitigation outside of the printer.
Not sure when I'll fiddle with that.

Did my first tests with vinyl filament using a small $10 roll.  Manufacturer recommended 260į max, but I had to go to 270į to get good layer adhesion.
The printer also shut off part way into the first print because the hotend wasn't heating as expected.  Not sure if this was caused by the enclosure temperature, or the high extruder temperature.
I ran a PID tune at 265į with the enclosure heated and the next print went fine.  The vinyl warped without a brim (on garolite, 110į).  With a brim it appeared to work perfectly while printing except for one corner.  The part seems to have warped after it was removed from the bed though.  I left it alone for a half hour after printing, but I guess that wasn't enough.  The chamber actually cools pretty slowly, which is good.
Next time I will try PVA glue on the garolite.  When I buy a big roll of vinyl it will be a copolymer, so that might be a lot less prone to warping.

Do those ---smurfing--- printers ever work?

 :lol

The Voron 2.4 has actually not had any issues other than stinking up the house.

This was the first thing printed on the 1.8.  It would probably be reliable, but will be torn apart and reconfigured anyway because it is a test rig.

The tool is the hobby.  (and it's a horrible hobby)

I realize that you gents are early adopters of this stuff and it is still evolving, but given tech pace these days one would assume it would be farther along in ease of setup/use/reliability.

It all kind of reminds me of my ex-wife.

The tech isn't that new.  The reason it exploded in recent years is that the patent for the process expired.  The heated chamber patent expired just recently.

What holds it back most IMO is the filaments.  They are extruded from standard industrial pellets meant for injection molding. Those plastics were originally formulated to shrink when cooling so they would pop out of the injection molds.  This is why plastics other than PLA warp so badly when different parts of the object cool at different rates.

PLA doesnt warp, but will deform in a hot car and degrades if placed in water.

I saw a story about BASF getting into filament a while back.  I am hoping they or some similar company formulate new types of plastic from the ground up.

It's all very cool stuff.

I would be an absolute menace if I had space, time and $$ for one.

The tech is about as evolved as it's ever going to get.  It's a low tech basis of operation, with a high tech layer applied over the top.  In other words, it's a glue gun (73 year old tech) with automation to mostly provide fine control of position and extrusion rates.

The problem with the whole process is not the automation parts, as much as it is with the glue gun portion.  Melting and extruding various different types of plastics, each with their own properties, even varying within plastic types, creates an ever changing target which requires skill and experience to hit with any sort of regularity.

The best you can hope to do without jumping in with both feet, is to try to spend your way into the hobby with expensive machines and using only filaments approved and sold by the machine's vendor.  Even that is fraught with potential issues related to head clogging and parts failure, which owners usually have to address themselves.

SLA is the future of 3D printing.  Resins are constantly evolving and eventually we may see very strong parts with fast cure times and simple cleanup.  Until then, it just is what it is.

Still planning to build a Voron, but a much bigger purchase took the funds I had set aside for it. I still wanted a upgraded experience, so I took the plunge and ordered a Prusa MK3S+ kit. Iíll use that to print my Voron parts. Iíve had great fun with the Anet, but Iíve taken it as far as it can go.

I spoke too soon.  The silicone wire for the proximity sensor broke internally in the middle, presumably from being rolled and unrolled inside the drag chain so many times.  This sent the nozzle crashing into the bed several random times and a few more times while diagnosing. Wasted over half a day figuring out the problem and running new wires.

 The sensor is normally closed and opens when triggered which should have prevented a crash. I dunno.

It never F-ing ends.

The good thing with Prusa is that a lot of the guesswork with materials is removed.

Honestly if I already had a Prusa, I would invest in the multi material attachment instead of building a Voron.  With an enclosure and dissolvable support material, it could print just about anything.
