Extruder not heating


When I start to heat the extruder it start from 76% but nothing happened , it not heating(stuck at 76%) any suggestion what is the problem?
best regards


are you able to tell if the hotend actually heats up, or is it cold? The problem may be caused by the heater&thermocouple, extruder cable or PCB. You can check the extruder cable as shown in step 4 - the extruder may start heating again when bent at some specific angle (there are multiple paths inside the cable, a problem may occur even if one of them is damaged).

However, if you go to the heating controls and the extruder starts heating automatically despite the heating is turned off - this could indicate the motherboard’s failure.
