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

Just wanted to say thanks for all the contributors to this thread.  I learned a lot plowing through these 19 pages.  I picked up an A8 and am having fun with it.  Still getting through some test pieces and upgrades.   :cheers:

Same here! This thread was a great resource/kickstarter.

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.

OK, thanks bud.  I have an old PI first gen collecting dust.  Allegedly it will work, so hopefully it's not too laggy.

Yeah, basic OctoPrint is dead simple to get going and SOOO worth it.  I love having 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.

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.

OK cool, thanks, I'll try some changes.

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.

Got some stuff from Ikea to make a full room desk for the printers and PC.
And started a large Vegeta model.(https://uploads.tapatalk-cdn.com/20180724/b82c4ae3efaeebae29a4dd9d066c5504.jpg)(https://uploads.tapatalk-cdn.com/20180724/b0d469de7b01d5a69ae8229f6d7d1f16.jpg)

05SRT4 can you print me a dog like you have in your picture?  How long did he take to print?  I like the model.
