I just got an Ender 3 3V KE printer. No problem printing pla filament. Just got some tpu filament and it’s not going thru the nozzle. I manually input temperature and still won’t go thru the nozzle. What am I doing wrong and what do I need to do?
Is it feeding into the extruder at all? Might be the tension isn’t right. When you do get it running make sure retractions are low <1mm or the filament could get caught up in the extruder. I have it running well on my V3SE, same extruder, had a minor tweak of the tensioner.
