Topic: clogged nozzle, how to clear?
My nozzle seems to have become completely clogged. I've tried clearing the top out as much as possible but I can't get any filament to go through. A bit of googling leads me to think I should be able to remove the nozzle and heat it to clean it out or soak it in acetone, but I'm not having any luck unscrewing the nozzle from the heating block piece. I've got a 7mm driver I'm trying to use and a crescent wrench on the block, but it's stuck tight and I don't want to break it. Am I on the right track?
edit - I loosened up the two grub screws on the block and was able to remove it together with the nozzle. The nozzle fits a 1/4" socket not 7mm, I don't have them separated yet though.
