I'm trying to help a long distance friend set up a cnc router. He has the demo version of mach3 and says he is only getting about 150 RPM out of the motors.
So my question is: Does the demo version limt the step speed to 500 Hz ?
Nope, I had my router running the demo version for a few months getting over 800rpm with 1/8 microstepping
