Help I need some assistance. I was in the middle of a print and my Ender 3 stopped feeding filament. It was trying to feed filament but no filament was coming out of the nozzle. I checked the and the nozzle was not clogged. The printer is new it's only a month old this is only my 4th or 5th print. Also, my screen on the printer has frozen a couple times and restarted is that normal?
