Dead extruder stepper on my ender 3 pro

Hi,I ran into a problem a few weeks ago, my extruder would stop pushing filament mid print, the steppper motor just stopped.turns out the heatsink on the stepper controller was knocked off by bad cable management. I'm using a SKR v1.4 turbo from BigTreeTech with TMC2130 stepper drivers for each axes and Extruder. I reattached the heatsink but it seemed to have died, everytime it tries to move the extruder now it jerks a little bit then stops responding. I have since replaced both stepper controller and motor, but it still does the jerk then stop, don't know if jerk is the right word, it doesn't make the full motion when trying to load or unload 5mm of filament, it vibrates a little like it tries to move the motor but doesn't have enough strength.I feel my only other option now would be to replace the motherboard. but does it seem likely the motherboard has been damaged?
