What should I do when the nozzle is jammed?

The reasons why the nozzle is jammed are varied, please follow the instructions below to troubleshoot:

1) Make you followed the steps in Change Filament to remove the previous filament from the 3D Printing Nozzle.

2) Make sure that the end of the filament is as straight as possible and that you push the button as far as you can. Or the filament will get stuck in the middle of the feeding tube.

3) Recall and write down the operations you performed before the nozzle is jammed. For example, I pulled out the filament without heating the nozzle.

4) Try to squeeze out the filament in the nozzle by inserting the new filament.

5) If the nozzle is still jammed after a few tries, replace the nozzle parts by following these steps.

Take out the jammed nozzle parts:

A. Wait for the nozzle to cool off until the real-time temperature on the Touch Screen is reduced to room temperature.

B. Power off the machine. Unplug the Module Cable and detach the 3D Printing Module from the X Axis.

C. Detach the side cover on the right using the other end of the screwdriver.

D. Use the provided Hex Key Wench to loosen the screw under the fan.

Tips: To avoid losing the screw, it is recommended to loosen it instead of taking it out.

E. Loosen the screw on the heated block.

F. Extract the heating tube and thermistor.

G. Press the button on the front of the 3D Printing Module and extract the nozzle parts.

Attach the new nozzle parts:

A. Press the button on the front of the 3D Printing Module and insert the new nozzle parts. Keep the highlighted side of the heated block parallel with its nearby side of the 3D Printing Module.

B. Tighten the screw under the fan.

C. Insert the heating tube and thermistor into the heated block. Part of the heating tube should come out from the other side of the heated block while the end of the thermistor should stay in the heated block.

D. Tighten the screw on the heated block.

E. Attach the side cover back to the 3D Printing Module.

F. Attach the 3D Printing Module to the X Axis and power on the machine.
