I need help so one day I left my printer on while I was gone and it ran out of filament so it stopped printing for a while and ever since it would print the first few layers, really bad quality and then it would stop printing the nozzles still moving everything but plastic wasn’t coming out. I’ve taking it apart and haven’t found anything yet. What should I do? I already tried extruding plastic it extrudes and then I start to print again and it doesn’t work
