Ok, I am up and running now. But Houston we have a problem!!! First I rewired all of my 48V connections straight to PS and eliminated distribution block on my high current outputs. This did not affect the situation I am about to describe.
So as stated in my OP I have x slaved to a. I have 300oz nema 23's 1.8°. Gear rack and pinion 24DP 15T gear. Running G214's at 10us. So my mach3 steps per rev are around 1000. I verified with dial indicator and running at 1084.312 mspr. Depending on kernel freq. And ess freq I can get rapids in jog mode over 500 ipm np issue, but only just jogging around. When I try to run an actual code ladder my slaved drive "a" goes into protect mode at anything over 60ipm. So I am assuming too much accelerated torque load is being applied to motor. But why just "a" and not "x" too? However in observing "x" I do see status led on gecko flash red momentarily under fast direction change. Using 12 awg for power leads on a 2.8A stepper.
Is it an issue of slaved axis? If I reduce micro steps I will gain more torque correct? Could I have too little backlash on pinion gear to rack causing a bind? (Doesn't seem to bind though). Any suggestions before I dump these for 600oz/in? Would i be smart to get a planetary geared stepper instead? Also I think I want to add encoders to my system. Opinions on encoder brand?
Thanks everyone
