¶ When & Why
- Every month.
- While driving the filament into the extruder, the gear encounters strong friction, which more or less produces scraps. As scraps accumulate, the friction reduces between the filament and the gear or U-shaped bearing bracket. Consequently, reduced friction compromises the extruding efficiency, and eventually causes slip during extrusion. Another adverse effect is that the accumulated scraps will fall into the nozzle and block it. In this case, you need to clean the nozzle or even replace it.
¶ Before You Start
Power off the machine.
¶ Tools Required
- Cotton swab
¶ Procedures
-
Open the 3D printing module.
-
Clear the accumulated scraps on the U-shaped bearing bracket using a swab or vacuum.
- Clear the accumulated scraps on the gear and its surrounding area using a swab.
- Close the 3D printing module.
