Doesnt look like it, cant see any potentiometers on the board to adjust.

I think I would first check voltages Out to motors, at Mobo connectors,
and see if that one is Lower than other 'E' output, (if it is a dual extruder printer)
(voltage is normally a little lower to extruders motor, than to other stepper-motors, someone said in a video)

If not that, then you may want to connect a voltmeter and monitor the voltage level while it is printing,
to see if there is changes in voltage during print. (like a temp related problem at Mobo)

( Of course that may Not be the problem and it's something wrong at the extruder )

It definitely the wires.

I swapped motors around and the right one started buzzes when it was connected to the left cables.
I swapped the stepper drivers around, still the same.
Swapped the cabled on the motherboard and the buzzing came from the right side this time.

So need a new cable....but ebay only has the motors cant find a cable on its own
