RE: [CAD_CAM_EDM_DRO] rapid G210 'overdrive' rates using logic on header blocks

The problem for me is not that I can't put out enough steps to get the rate
I want. I am running a fast enough computer that I am getting an adequate
step rate. The problem is that if I use a set of G2XX stepper drivers the
torque will drop off with the low voltage at a pretty low step rate.
