Hi could someone please help my creality printer hasn’t been in function for months now due to having technical problems with the heats. This is really frustrating as I want to get back to my project. The problem is that on the screen it has two symbols one for the extruder and one for the bed the extruder is normally room temp when switched on and was showing around 18 degrees
and now showing -14 which I don’t understand so to hopefully resolve this problem I got a new extruder part that contains the hot end and thermistor then tested to see if it has done anything but no luck so brought a new motherboard thinking this could be it but again no Luck I would upload pictures but not allowing me to do so !
