Please help me check my Chinese CNC 3040 (it was working perfectly fine) controller unit has stopped operating the stepper motors(https://www.oyostepper.com/).
I checked the fuses, cables etc on the circuit board and the Mach 3 on the PC is also working fine. The keyboard is connected fine with the Mach 3. The spindles on the control unit are fine but there is no movement from the stepper motors.
The circuit boards in the unit are: X, Y, Z axis board = JP 382A. Power supply board – JPQD-V11. Any suggestions for a replacement or new control unit are welcome.
Thanks
