Hey all, starting a build of my 2nd MPCNC, with a specific goal in mind of trying to make a machine a little better for learning multiple setup CAM operations, and hopefully a bit more effective for aluminum milling. It will be 24"x24", with a goal of having a cutting area of 14"x10", the primary work-holding will be using a drill-press vice, and possibly a machinists vise in the future. I’d love to get some feedback or suggestions, I plan on experimenting with this build a bit to get a more rigid Z axis, and I am willing to give up a lot of cutting area to get there. This is a work in progress so stay tuned.
Original 32"x32" MPCNC (I will be breaking this one down and placing the new machine in the center of the table, already center cut to 24"x24". I use a vinyl shower curtain for dust control. This machine runs a Dewalt 611, I have a 400w brushless spindle on order for the new machine to try out.
Examples made on the original machine. Tolerances generally around 0.1mm, but the Z axis definitely is not square.
Printer is chugging away making new parts for the J version.
I’ve ordered 0.065" 316 Stainless tubes, all 24" length, and some 80/20 1"x2" for the frame.
316 Stainless ruining my band-saw blade in 30 seconds.
Pipe cutter was much more effective.
So I have legs cut now, waiting on parts to finish on the printer and hardware to arrive via amazon. Stay tuned as I experiment with the rest of the build. I’ll try to update this page with anything that I try, whether it works or not.
