Hi there,
I am having issues with my kossel xl that i built a couple of years ago. For some reason, the extruder is stripping out the filament after about an hour of printing. I initially thought it might have been a clog in my hotend, and i do believe this may have been an issue as when i took it apart to check for a clog, there was a lot of plastic on top of the hotend cube (an e3d v6), so i think it was leaking a bit. I gave the whole hotend a good clean. I also took apart my extruder and cleaned the gear to make sure there was no filament dust causing problems. I then tightened the extruder so that it would grip the filament tighter.
An hour into the next print, filament stopped coming out of the hotend...
I am printing at 200 degrees using rigid.inc PLA which i believe is fairly high quality.
This is the shredded end of the filament
This is the normal pattern in the filament.
Any help is much appreciated,
Thanks,
Tom.
