Extruder Stepper Driver Enable Pin Stuck 3.3V High
#1
Suddenly my extruder stepper stopped working. I noticed the "ENA" pin is stuck on 3.3 V (high) regardless of of commands. The driver works fine when used on one of the other axes, so it appears to be a problem with that circuit on the main board. On all the other drivers, ENA goes to 0V while the motors in operation. I assume this to mean logic 0 enables the steppers.

Any ideas as to why mine would be stuck high?
