So my MX3660 powered machine stopped cold in its tracks yesterday.

I can still move axis via a Gecko G540 that is in my control as well. This includes the steppers that were previously connected the MX3660.

After opening the control two of the axis show a Estop fault. The other drive shows over current, even when nothing is plugged into it.

Is there a way to reset this fault? Or is the drive damaged?

Just to be clear, the Estop is not on in the control software (UCCNC) and can be turned off and on via the two Estop buttons succusfully. The MX3660 blinks the Estop fault on those two drives, I suspect because the third drive is over current?
