Have got 5 tables running with 3 different motor/gearbox combinations and 2 different rack suppliers/pitches. ALL of them were set to the calc and needed no tweaking afterwards.

Please somebody give me an advice. If my Motors 86HS9802 is
200 steps * 10 microstep = 2000
2000 * 3 times belt reduction = 6000 steps per rev
travel per rev = 3.14159265 (tooth distance = Pi) * 30 tooth = 94.2477796

steps per mm = 6000 / 94.2477796 = 63.6619662
what "Move speed mm per minute" and what "Min freq. kHz" is ok to use thank you

Those are rapid move G0 feedrates. For cutting I rarely use over 4000mm/min

Was this whole conversation, a discussion on what Mach 3 does automatically for you when you tune the motors?
