I been having a problem with mi x1c extruder, the printer print’s normally but some times the extruder just clogged and stops working, I noticed that the filament gets thicker in the part where the gear tightens, I thought that was the filament that i was using (Grilon 3 brand) but recently I have change the brand to Elegoo but I have the same exact issue, some times it just continues working after the repair but some times it clogged again, all the filaments that makes that problem are PLA. Also the nozzle, most of the time isn’t clogged. I add some photos of the problem. I wish someone can help me!
