It is heating up. Tried pulling the filament while unloading but it didnt come out I am using the original PLA that came with the MakerBot. I think the problem could be that when I print the plate is too close to the extruder tip, although I do level it each time. Read somewhere that that can cause melted filament to back up into the unheated part of the extruder and cool.

Guess I'll have to open it up again.
