I kicked off a print over the weekend, and came back to print stopped because the filament wasn't feeding. I assume the nozzle is clogged, but the problem is I can't get the filament out of the core. I saw a similar problem where it was suggested heating the core up to 280 to soften the filament. Tried that, heating it up for 30 minutes, but still couldn't work the filament out. Any other ideas on getting the filament removed would be very appreciated!
