Hey all, I bought a cnc recently and "upgraded" it to Mach 3. It was used and iv rewired the entire thing added a Mach control board ect. I'm running Nema 23s on all axis, ball screw is 1 inch I Believe. Current tune for each motor is set to 600 steps, 239 velocity. This is just a randomized figured Iv put in to test the machine. Mach is set in inches, I have about 7inches of plunge on my z, however instead of reading - 7. 000 it reads like -189.00. Which is more closer to mm scale. How can I get this to accurately display an inch scale? Is this a motor tuning issue? Eg 600 steps is equivalent to 239mm? Would I just have to do the math conversion and set it accordingly? Or is there another set up page in Mach that I missed?
