Mini Mill Conversion - best stepper drive choice

[JAZZCNC]

Some of this depends on motor type 4 or 8 wire. With 4 wire your stuck to how motors are wound at factory, often series. 8 wire can choose which.

My choice for small Mill would be to go with AM882 with 60-65vdc and wire motors in series. This will give you more torque down low and seen as you won't be going fast there'll still be plenty of torque left up high. The reason you need 60-65V is because series requires more voltage to get decent speed.

Router then you'd wire motors parallel because want more RPM and torque to run higher up the rpm range. This does come at the cost of losing little lower down.! . . . Can't have cake and eat it I'm afraid.

The AM882 will offer more motor choices and upgrade potential if required. There advanced Resonance handling and smoothness are worth paying that little more for IMO.
