I've looked through other build threads, and what I have yet to find is good information about the correct size stepper motors to use with mini-lathe.

I've got a G540 control box ready to go, so I'm limited to its 48 volts, 3.5 amps.

I can put the best possible stepper on the Z, which is a Keling KL23H2100-35-4B. This is a 381 oz/in motor that works best at the volts and amps of the G540. The problem is, it's way too big to work on the X axis. I need something smaller and lighter for that location.

What are you guys using on your mini-lathes? I'd like to hear torque ratings and dimensions of the motor, specifically, the length.
