I was trying to fix a friends faulty M2. The extruder feed was jammed. Unfortunately, another problem was that the wires to the small fan on the front of the extruder feed assembly were previously broken off and hanging free, and they accidentally touched the metal filament feed roller whilst it was all turned on (I was heating up the blocked hotend in order to be able to clear it.) I think that shorted something, and now the whole thing doesn't turn on

I will check at the fuses on the electronics board when I next get a chance, but does anyone know whether it's likely to just be a blown fuse or have I fried the electronics board or something else?
Thanx in advance, Pum.
