Dismantled the printer ,at least the electronics and reconnected everything.
Also disassembled the hotend once again.
I swapped the stepper from E0 to E1.Same happens.
Also swapped the hotend from E0 to E1.No difference.
Well looks like I am out of options.
What should I do?
Should I bother to get another motherboard or sell the printer and get another one?
