I am pulling some parts off of the shelf to put together a router. I have a 12 VDC power supply, Stepperworld FET-3 stepper board, Mach 3 software and NEMA 34 stepper motors, 1.4 amp, unipolar, 8 wire.
I initially ran the steppers using K Cam just as a test (the first PC was a Win 98se machine) and the motors ran strong in both directions.
I then took this system to another system that runs Win XP Home and Mach 3 and configured it to run with this hardware. I have a really strong X-axis in both directions. My Y and my Z-axis are strong in one direction and I can hold the shaft from turning in the opposite direction.
I have checked and doubled checked the cable wiring and stepper motor driver board wiring. I have also changed the step signal to operate low with the same results.
Can you help me look for what I missed? Thank you.
