Dq542a stepper driver stopped working
Hi Hope someone can help me here. I have recently built a raw 1.5 (kit machine) and was running it for a few days with excellent results.
I have 4 Wantai DQ542A drivers, driving 4 nema 23 motors.
1 x axis motor
2 y axis motors
1 z axis motor.
I switched on the machine this morning and when I started to jog the gantry (y axis) out of the way so I could mount a new workpiece when I noticed only one of the Y axis moved so I stopped immediately to avoid any damage. When I looked at the electronics I saw that the driver that was not working had no green led lit like the others.
I opened the driver and checked the fuse and it's fine.
No idea what the problem is or what would have caused it.
I would love if someone could help me out.

Check the wiring, and che k the voltage with a meter.

Swap inoperative Y driver with the X axis driver and verify that power is correct at the Y driver.
Either defective power or the driver.

Driver is not normally repairable, but I would at least open and inspect the circuit board carefully for "Open, broken" circuit components.
The DQ542MA are available on ebay
