My Ultimaker has finally died after several weeks of intermittent faults.
Now it have found that one of the stepper drivers is crashing everything, if i unplug it the ulticontoller works, plug it back it everything goes blank or starts the stepper motor it is plugged into pulsing.
One of the other stepper drivers has a bit missing see photo.
Does it make sense for a stepper driver to have this effect?
