So after I upgraded my CNC lathe to the latest Mach release, forgot which one it was, there was something different about how it puts out its pulses, and I had to lower the max rapid speed to keep it from stalling. I used to have 55"/min rapid on the Z axis, now all I can get away with is 35"/min. SO, I was thinking of going to a larger stepper motor on the Z axis. It has a NEMA34 640oz/in now, I could easily go to the longer 1200 or so one. I know, more voltage is the answer but I am stuck with the 42 volt system I have now. Question is, will the larger torque stepper give me more speed on the same 42 volt supply? Thanks to all.
