I'm having trouble with the extruder on my Ender 3V2. I noticed it when one of my prints seemed to stop halfway through, and now no filament will go through the nozzle. I have cleaned the nozzle, so I doubt it is clogged. I also cannot remove the filament. I don't know what to do. I've only had this printer for a few weeks, so all the parts are new. if anyone has any suggestions, that would be amazing!
