RE: [CAD_CAM_EDM_DRO] Microstepping

The current in the coils is manipulated so that each full step (normally
200 per rev) is broken into smaller increments. With a 1/4 step drive
you would now have 800 steps per revolution and with a 10 microstep
drive (Gecko G201 among others) you would have 2000 steps per motor
revolution.
