Sorry for all the questions, seeing your robot fly off the bridge with 3d printed wheels was what really planted the seed of 3d printing in my mind last year, so being able to get responses is very nice.

We do ream and tap after printing, but usually for a reason other than tolerances (post creation modification, tap for a screw, etc.) we don't drill, it usually results in cracks. I'll get Lucas on here in the morning to answer your more specific questions as to the printer.

The cams we machine ourselves out of aluminum on our CNC.
