I haven’t updated my build in awhile, so here it is. I planned my cutting size to be 48×32, but i didn’t take into account my dust collection pipe (which is a necessity, and works amazingly), so I get 31.5 x 48.5 cutting size. I installed a spoilboard, leveled it, and put in T-nuts every 4 inches, and then 3d printed some hold downs. I put end stops on X and Y for homing, so that when i switch bits, i can continue a cut and have everything line up perfectly. I also made a “touch plate” to make sure i’m homing Z consistently.
I use this machine DAILY. I still need to do some cable management, put the ramps and arduino in an enclosure with a fan, and figure out why the Z axis isn’t as sturdy as it should be, but other than that, it’s freaking awesome.
