General Mach Discussion / setting up mach3 for the first time - driver test "no driver sensed installed"

« on: March 02, 2021, 10:30:24 AM »

I am having a hard time with mach3 running my nema 34 motors.  I started with the usual setup and when I tried to jog the motor I hear it click and then the driver trips.  I have tried resetting the dip switches to 0 and adjusted the steps per inch in the motor tuning to 20,000 steps and then I get the spindle to spin but once it stops, the driver trips again. there must be either a setting off or the voltage / amperage is messed up.  I have rewired this thing multiple times and I don't think its a wiring issue at this point unless the wiring instructions were wrong.  I ordered all the motors, drivers, interface board, power supply from buildyourcnc.com but they are not helpful. does anyone have any suggestions?
