Creality CR-10 S4 err change filament.
Hi from out of nowhere I have started to get err change filament every time I go to print, changed filament run out sensor with 3 different ones changed firmware and even changed board from a V2.1 to a V2.2 and still get err change filament. Will end up with hammer out shortly or change motherboard out for another make. Is there any body out there that has had and solved this problem. Regards Ken
