My CR-10 V3 started jamming recently. It’s never had an issue before now. I first I did all the usual checks. I even suspected some dimensional problems with the filament I was using. But after attempting to eliminate all possibilities, I realized it was the filament runout sensor causing the jam, because 1) it seemed to be impeding the flow of the filament and 2) it finally jammed completely. A piece of filament has broken off inside and won’t come out. I don’t want to force it too much.
I’ve noticed that the brass insert has worn from the abrasive filaments that I use, which is probably why the poor flow/jamming started. I’ve the removed filament sensor for the moment until I can get the filament out, but then I’m likely to have the same problem if I clear it (see wear photos). I’m wondering if I have to buy another sensor or is this repairable?
Can Creality replace it under warranty, or is it my fault for using so much abrasive PC/CF filament?
