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.
