General Mach Discussion / Stepper motors slow
« on: October 31, 2017, 06:55:34 AM »
Hi there,   I build my own CNC plasma using Bobcam cad v64 and Mach 3 on my lap top with windows 10 and USB port  , driving 3 nema 34 steppers. Everything is working fine exept my cutting speed is slow but jog speed is fast. I had issues with my metric conversion that seems to be working now. I changed inches to millimeters in my post proccessor but did not insert my G21 in the beginning of my program could that be the problem. Please help as it is my first try at the CNC game.  Thanx guys
