Re: [CAD_CAM_EDM_DRO] Re: Microstepping thru the Tulips

This is true. At high speed inertia will make sure that rotation is
smooth anyway. Even if the current waveform did follow the microstepping
it would have negligible effect on motion. Where microstepping really
scores is at low speed where you get a huge improvement in smoothness
and much less resonance.
