Re: [CAD_CAM_EDM_DRO] DenverCNC?

I can certainly attest to this. Microstepping drives make a HUGE
difference. It is similar to stating the HP figure for an automobile and
thinking that this is the only parameter regarding performance. The HP
figure is at a single RPM value on a continuous curve, much like the holding
torque value is a single data point.
