The extruder suddenly stopped working after I cleared a jam that caused it to grind.

• I tried every combination of motor and cable to trace the problem. It seems the only fault is the extruder's motherboard connector.

• The motor is functional. I connected it to the XYZ motor cables and it spins on every one.

• Nothing happened when I tried plugging the other axis cables into the extruder port on the motherboard.

• Finally, I am comfortable using a multimeter and soldering iron, but don't have immediate access to them.

I really appreciate any advice on this because I miss printing!
