Polyprinter issue?

Just got to the space and it seems like there’s an issue with the polyprinter.

When I got in it was hot and the motor on the extruder was spinning but nothing was coming out. I tried to reverse and extrude the filament that was there, it wouldn’t budge. Based on Skedda, noone has been on the printer since 10/12, and that seems like an awfully long time for it to be hot and for that motor on the extruder to be running. Anyone know what’s going on here?

I forgot the clean the drive wheel. Sometimes the grooves get filled with filament.
