Hey there, apologies for what is probably a simple question.
I have recently built my prusa I3 Hephestos and am struggling with getting the stepper motor on the extruder to function.
I have checked that it is wired up correctly (the colours were wrong in the kit but they go to the right place so little matter)
If i try to manually jog the motor it doesnt respond at all, but if i try to load filament it pulses.
I've checked that the motor itself is functional by plugging it into another axis and manually jogging it and the motor works perfectly.
Would anyone have an advice on where to start? I am useless a most things electrical
