Hello folks,

My first message here. I got ZAY7032G for the price I could not resist. I would like to convert it into CNC, but the round column is a problem (the quill won't give me enough movement).

Question: to get rid of the head losing vertical position why wouldn't it be possible to make a guide rack out of linear slide and mount it on a column instead of the existing gear rack. After that take the crank mechanism out of the cast milling head holder and attach pillow blocks.

It should not be a problem to mount a ballscrew for Z axis.

Best, Mark
