Sorry for being inconsistant in my subject and post! I have steppers not servos. Here is a list of Keling equipment I have. KL4030 drivers, 2100-30-4B stepper motors, C10 breakout board, 30V/9.7A power supply, and a 5V power supply. I have double checked my wiring and calculated my motor tuning for the Mach setup. I have set the dip switches for 1/4 stepping and 3.0 amps based on having a 1/2-20 double start screw. I hope this helps.
Thanks again,
Bill
