Filament gets rubbed off

Recommended Posts

Hello everyone,

After weeks of reliable work my UM2 failed after i changed the filament once.

The extruder motor rubs off the filament because the PLA gets stuck. I had the same problem with ABS. I already cleaned the nozzle using the "atomic method" and the filament still stucks and the motor rubs the material so hard that it can't be pushed forward anymore.

What could be my problem?

Thank You,

If you don't cut the filament to a point, sometimes it gets stuck inside the head. You can tell because nothing comes out of the nozzle. Is anything coming out of the nozzle?

Or your nozzle could be clogged. Try the atomic method but also with a needle pushed from below through the nozzle hole. You can buy hypodermic or acupuncture needles at .35mm.

Or you can remove the nozzle completely and burn out all the gunk with gas flame.
