I have been able to get my axis moving however they will only move enough to get the line count to go to the fault mode at the drive. I am sure I have something in setup goofed up but wanted to run some things past you guys to see if I am missing the forest for the trees. I have a PMD-126/107 going to Gecko G320X drives controlled by Mach III. I have CUI encoders set to 500ppr and my lead screw requires 5 turns to make 1". I set up in Mach to have 2500 pulses per unit. The drives move accordingly so I am confident that I have the pin #s setup correctly for the servo output from Mach. Do I need to run a "charge pump" to make things happy?
