lyta 0 Posted November 7, 2014 in Filament gets rubbed off 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, lyta Share this post Link to post Share on other sites
gr5 898 Posted November 7, 2014 in Filament gets rubbed off 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. Share this post Link to post Share on other sites
