General Mach Discussion / Part diameter shrinking .003 every part
« on: April 01, 2013, 09:02:58 PM »
I am running a Sherline 4000 lathe using mach3 for controls. I have a 200 step motor i think...400 step with Sherline 1/2 stepping?
I have my Z axis steps set at 16000 and my X axis set at 8000. My Z axis has no problem holding its position but every part i run my O.D. shrinks by .003. I have tried calling Sherline support but since I'm controlling it with mach3 they said they cant help me. i have my accel and velocity both set around 17 in motor tuning. I have tried 1-5 on step pulse and dir pulse with no luck.
Any help would be much appreciated!
Thanks, Josh
