Re: [CAD_CAM_EDM_DRO] Microsteppeing drives

A micro stepping drive is better than a full step drive in
that friction could cause a micro stepper to not move for
several steps but then the next micro step would cause the
motor to catch up and be "in position" kind of like
slip/stick in a servo at very slow speed. If a full step
drive misses a step, it has stalled.
