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 )
