CNC-2116 - Up and running, sort of (2015-03-21)
Yvan256:
Thanks for the feedback, mcseforsale.
The MDX-3 is has been cutting the first panel of CNC64 for about two hours from an estimated cutting time of around three hours. I need twelve of those plates for CNC64, which means roughly 36 hours to cut these simple assembly plates. :dizzy:
Now you see why I'm building CNC64!
edit: It took the MDX-3 about 2 hours and 28 minutes to cut this small plate (shorter than my 3 hours estimate), meaning twelve plates will take around 30 hours, so 27 hours and 30 minutes to go for the other eleven plates. The rounded corners certainly didn't help the cutting time but I was getting tired of making rectangle plates. Nothing says "CNC" like rounded corners! CNC64 completion countdown: 36 panels to go.
edit2: here's a partial preview of CNC64 in Sketchup. You can see where those 12 plates go.

I forgot to mention that I modified the RTX by following these instructions (thanks cre8er!) because the speed dial was really hard to turn, I couldn't imagine turning that dial once the RTX would be in place in the CNC mount. After that small and easy modification, the speed dial is now very easy to turn. :cheers:
I now have four panels ready to build CNC64, those are small panels used to join other panels end-to-end. The holes are a bit smaller than the bolts to allow the threads to run into the MDF and prevent any movement once assembled. I had to dump the first plate with the rounded corners because the holes were 0.5 mm too big in diameter.
I switched back to rectangular plates to save about 10 minutes of cutting time per plate and because the MDX-3 was doing weird noises while cutting the rounded corners. I'll let CNC64 make rounded corners when cutting the parts for its clone.
I promise the next few parts will be more interesting to look at. ;)
That's 4 plates done out of... 42.

(cheesy TV announcer voice) "Tired of looking at small rectangles with round holes? How about looking at a longer rectangle with holes and tabs?"
As seen in the Sketchup render in a previous post, this is one of the two side panels.
The first image is the 3D render in Sketchup, the second image is the 2D render in Sketchup with the milling bit circles all around the part to calculate the polygon outline coordinates. The third image shows the cutting outline path in my own web-based "CAD" program, if you can even call it that. The photo shows the MDX-3 cutting the panel.
edit: the last two photos show the beginning of the assembly. Don't mind the small part at the front of the panel in the 5th photo, it's just my test plate for the new joint I talked about. The MDX-3 is busy cutting the same panel again for the right side of CNC64. The next two panels to be cut will be either the other half of the sides or the front of the machine. Five plates done, 40+ to go. I'm also going to need longer bolts for assembling these small plates...
edit 2: the very last photo shows the six panels that are ready and assembled and the two sides roughly at the correct distance from each other if all parts were there. I also need to paint the other side of the long panels as well as the edges of all six panels. I know it's not an arcade cabinet, but I just can't wait to add more panels for the base! 8)

I'm not sure people still read this thread judging by the lack of comments, but then again there's not much to comment on. I apologize for those boring updates. ;)
The MDX-3 is cutting the first front corner panel that will connect with the long panel from yesterday.
edit: wow, 6400 views :o
edit2: added a photo of the final part, the MDX-3 is busy cutting another for the other side.
edit3: another photo, the front left corner of the first CNC64 is complete! The other Sketchup screen capture shows a corner that will be added to the first CNC64 clone for added strength. I made this update while the second long panel was still being cut yesterday, we'll see if I need to cut them again to add these corners once it's complete.
Drnick:
Don't apologise for Boring updates, At least you keep giving us updates. Gonna be fun when you finally have 2 cnc 64s busy making up the big brother cnc256.
And on top of that, reading this is still better then staring at ping traces trying to work out why we keep losing connection to one of our DNS Servers. :angry: :angry: I am sure that the problem is in the routing :dunno
