Hi, Iv been having trouble with extrusion on my ender 3 and i don’t know what it could be. the filament that is being extruded is coming out at various thicknesses and causing a lot of resistance when its doing so.
my initial thought was the extruder is blocked so i preformed a cold pull then i replaced the nozzle and put it back together and it still persisted. the image of the filament shows the inconsistency and i got measurements of over 1 mm thickness with the nozzle being 0.4 (also a new nozzle so not damaged).
ill try be as detailed as i can to narrow down any suggestions:
i tried temps from 195-235,
made sure the nozzle has that small gap between the heater block so the nozzle can be tightened fully,
i heated the nozzle to 235 when tightening the nozzle,
i made sure the bowden tube had a flat cut and i marked the tube to ensure it wasn’t dislodging,
the filament is geetech brown PLA,
i also have the bulls eye cooling upgrade on with a silicon cover,
when testing the extrusion of the filament i turned off the part cooling fan to reduce any resistance,
the filament is also extruding straight as long as its extruding very slowly
