Hi all,
Was printing a 27 hour piece for work and I came back to the piece being a mess of extreme curling at the edge and spaghetti PLA everywhere (picture 1) while the nozzle was still moving with no extrusion. I realized by googling that the feeder was grounding down the filament (picture 2) so I followed the steps to release all the tension (indicator is all the way to the top). Next I re-feed the PLA and start the print once again. This time it prints the first layer and quits extruding. I googled once again how to unclog and follow the Atomic method and the filament flows nicely out with me manually inserting the filament.
I try the print again and it does the first layer okay and quits extruding the second layer. I do not know if it's the feeder or the head? I changed the tension on the feeder multiple times with the same result. I did the Atomic method multiple times on the head and nothing seems clogged.
What is consistent is that the feeder does grind the filament at medium tension and no tension, and also when the head stops extruding: the filament looks swolen (third picture) as if it's heating up but it has no where to go.
