Here is my MPCNC that I have been slowly making progress on. I was going for an Iron Man color scheme. If you couldn’t tell.
The working dimensions are 19 x 19 x 3 inches. This allowed it to just fit on the cabinet I was able to snag from work.
I’m currently finishing up the wiring and belts and hopefully should be able to run some initial tests soon.
I plan on using this primarily for wood but I want to try my hand at aluminum and steel eventually.
I am going to build an enclosure for this where I can lift the sides to be able to run longer pieces on it.
I am quite surprised at how sturdy this is given its cost and materials. Props to a nifty design.
How level should the rails be with the table top? All my rails are currently +/- 0.2 degrees. I figured that should be fine but wanted to double check if I should try to improve them.

Looks good, good size, don’t worry about the angle for now just get it dirty!!!

I’m making progress .on mine too. It’s gonna be 36×24. I’m in Rochester Hills.May 19, 2019 at 1:55 pm #100936

Yours is looking good as well. Is that your working dimensions or outside dimensions?
I used to live in Rochester Hills but moved down to Sterling Heights last year.

I finally got some time to finish the wiring and start on some drawings to test it’s performance.
Here is a picture of the crown drawing. I ran it a second time over the first one just to confirm its repeatability. I am happy with it.
I then wanted to test the accuracy so I created a simple design that I could check how square it was and its dimensional accuracy. everything looked and measured close enough. I’ll probably run another calibration test like this after I attach the router and can measure parts better.
Lastly, I have seen some people draw Mayan calendars to see how it performs with lots of details. I figured I’d run something similar and more fitting to my color scheme. And why not throw a Star Wars one in there just for the fun of it.
Overall, I am very happy with how it is performing so far. Next time that I have some free time I will be attaching the router and finally getting it dirty.

36×24 are my working dimensions. My table is 48×36.May 22, 2019 at 4:59 am #101246
I had some time yesterday and was going to try some cutting but little one went down early and I didn’t want to wake the baby so I ended up adding a spoil board and cleaned up all my cables. I really like the tape measure trick, it was simple and cheap and looks pretty nice. I decided to add an upper bar to mount the y axis cables to so that it would leave the side open so that I can run long boards through without the cables being in the way. It also gave be a surface to mount the electronics onto until I enclose it.

+1 for the tape measure trick! I really like the way you have your spoil board set up. I might have to give that a shot on mine. The easy swap spoil board.May 22, 2019 at 9:34 am #101271

Thanks. I needed a spoil board and because I was going to use a thin piece of MDF I wanted an easy way to swap them out. The spoil board is a standard 2ft x 2ft piece of MDF so I just need to buy another $4 board when I need to replace it. Nice and easy swap.
I also plan on adding threaded inserts in the bottom plastic board and then have through holes in the MDF. That way when I replace the MDF, I can just rerun the through hole gcode from a close enough staring spot and I wont need to replace the inserts.May 22, 2019 at 7:13 pm #101319
Dui, ni shuo de duiParticipant
Very nice build so far, kudos!
