Help please with motor tuning mach 3.

[JAZZCNC]

The main bennifit to higher micro stepping is smoother operation at lower speeds but it does come at a cost with higher velocity unless your drives can morph the steps as the RPM's rise. It also makes the parallel port/Mach work harder has it as to deal with more pulses per second.

If you don't want high velocity and the PC/PP are good for it then stick with higher micro steps has you'll get smoother running motors.

Edit: Micro stepping really shouldn't be used or thought off has increasing resolution it's mostly usefull to smoother running motors at low RPM's. Best advice is play around untill you find the sweet spot, not all motor/drives/BOB combo's perform the same so playing around stepping can change a machines performance greatly.!

Edit2: Oh and every time you change the stepping you will need to re-tune the motors for best performance.!
