This is actually my second version of this, first I did it with steppers, then sold the complete stepper system off it when I converted it to servos. I made two major changes to the machine. First, the Y leadscrew bushing had no bearings in it, so I bored out the bushing block to accept small bearings just like the X axis of the machine. (Can't understand why they have paired ball bearings on X and brass bushings on Y.) The second mod was to retrofit a ballscrew to the Z axis to bypass the very coarse rack and pinion drive. Since I have a Bridgeport, I use this machine mostly as a drill press and for demos. The 4" Y travel is the most limiting feature.
