Hi, i need some help/advice on setting up stepper drives, Currently trying to CNC my lathe i have a 14mm dia x 4mm pitch ballscrew for the leadscrew and a 8mm dia x 2mm pitch for the cross slide.

i have a Nema 23 on the leadscrew and a nema 17 on the cross-slide. these are driven MSD542's powered by a 50V DC 10A power supply.

I have setup the micro drivers to 8 microsteps, Is this possible too much? as the motors sound rough.

Some background ( i had the drives etc working on the old 8 TPI leadscrew) so there is no problemas with power motors or drivers..

Thanks
Roy
