RE: [CAD_CAM_EDM_DRO] Re: Wanted: Servo Motors that interface to Gecko 320

Ok, let's assume that we are using a .2 inch per rev lead screw on this mill
with 500 cpr encoders. That would be 500*4 = 2000 pulses per rev. 2000*5 =
10000 pulses per inch * 120 = 1200000 pulses per minute. 120000 / 60 =
20000 pulses per second for 120 inches per minute. Mach2 can run at 45000
pulses per second so you could easily get 120IPM on both the X and Y axis
during a rapid move.

DeskCNC will run at 125,000 steps per second in Windows and several
of the DOS based controllers will also run up to 75,000 or 100,000
steps per second.
