Hello, I was printing fine and suddenly no more filament was coming out. I looked for a clogged nozzle, but that was not the case. Found instructions on how to remove the hot end and saw the filament was stuck on the hexagon, or more exactly just out of it. I managed to remove it, put everything back together, feeder some filament manually (PLA) and it started working again. Then after a few minutes it happened again. So I repeated the process. This time, after manually feeding the filament, I sent the print job, but no filaments was coming out at all. Yes, I thought it might be a defective filament, so got a new one out of the box (PLA), but it did exactly the same thing. I changed it again for ABS this time, but same result. Manual feeding works fine, but then it does not print anything. Attached is a sample on how the filament gets... its stars making some sort of coil right at the hexagon entrance. Please help! Thank you!
