Printer not extruding filament
I'm a newbie to 3D printing and just started this past month or two. I got my first printer, the Prusa Core ONE, and so far it's been working great.
Recently, I tried a print, and I came back to it being printed halfway. The printer kept going as if it were still printing the rest of it, however, it wasn't extruding any filament out of the nozzle.
I checked, and I wasn't out of filament, so I assumed the reason that no filament was coming out was that it was clogged or something. I looked up tutorials on how to clean it, but nothing has worked so far. I tried sticking the iron rod up the nozzle, I tried heating up the nozzle and extruding it through the control panel, but nothing worked.
What else can I try? I'm hesitant to unscrew the nozzle because there aren't many tutorials online for the core ONE, so I'm nervous I'll mess it up.
