Optiumum MH50G CNC Conversion: Y-Axis

CNC conversion of this Optimum MH50G milling machine is work in progress. I've just completed the conversion of the Y axis and running a first test.

Did you ever complete the CNC conversion? I have a similar machine and was wondering what you did for the Z axis. Did you install a ball screw and brake, or just leave the existing screw in place and replace the motor?
