Looking at purchasing this 1 axis closed loop driver/motor set for Z on my mill and would like your opinions please good &/or bad.

I have a 60VDC power supply to run it from.


The bog standard stepper set I have at the moment has too much torque (12nm) by the sounds of it.
Resonance issues make it practically unusable. 8mh inductance figure isn't helping either I reckon.


Thanks in advance.
