What should I do if the filament won't load? – Snapmaker

When printing, the filament does not come out of the nozzle.

Possible Causes

The nozzle is jammed.
The filament is not inserted properly.
The 3D Printing Module is malfunctioning.
The port of the Controller is broken.
The Toolhead Cable is broken.

Actions

1. Check whether the hot end is jammed.

- If yes, clean the hot end.

a. Heat the nozzle to 225℃ (If it is a PLA filament, please heat it to 225 ℃. If it is an ABS filament, please heat it to 265 ℃.) and use a metal stick to clean the filament inside the module by pushing them out.

b. If the filament cannot be pushed out, it indicates that the hot end (nozzle) is clogged, please

refer to this video to replace the hot end.

- If not, proceed to step 2.

2. Check if the gear inside the 3D Printing Module rotates.

(1) Turn on the machine and open the latch of the 3D Printing Module.

(2) On the Touchscreen, Go to Control > Nozzle. Set the nozzle temp to 200℃ and then wait for the nozzle to reach the target temp. Then tap Load or Unload.

(3) Check whether the 3D Printing Module gear is rotating.

- If yes, then the 3D Printing Module, the Controller, and the Toolhead Cable are intact. Make sure the filament is inserted properly and then close the latch. Try loading the filament again.

- If not, check whether the toolhead port of the Controller is broken, proceed to step 3 and 4.

3. Use the 1.6W Laser Module to verify whether the toolhead port of the Controller is broken.

(1) Turn off the machine and connect the 1.6W Laser Module.

(2) Turn on the machine, go to Control > Laser Power.

- Toggle ON Laser Status to see if the blue laser light comes out.

- Toggle OFF Laser Status to see if the blue laser light will close.

- Adjust the laser intensity and observe whether there is a significant change.

- Check whether the indicator light of the 1.6W Laser Module camera is green.
