    Enders 3 extrusion stepper motor

    Hi not sure if i have a problem or not , I have just purchased an enders 3 first few days printing was going ok after I took the glass bed off , could not get anythink to stick to it but now I have noticed a clonking from extrusion stepper motor , it clonks and the shaft shifts back about 1/4 turn, I thought it was the little grubs screws holding drive wheel that had come loose but its not them , is this normal or has somethink come loose in the motor itself.

    No, not a stepper problem. What is happening is that the stepper is trying to push filament through, but there is either an obstruction (clogged nozzle) or your temp is dropping on your hotend. Think of your filament as a spring that is being compressed. Eventually that spring overcomes the stepper motors ability to keep pushing and it is pushed back until the stepper can push again. Clean your nozzle and watch your temp on your hotend.

          Glad to hear you are up and running again. Most extruder problems are either temp or blockage if the rest of your machine is ok.
