Filament jammed in the extruder

Was part way through a print and noticed no more filament was feeding through.

Opened up the, um, two spring screws and found the filament eaten by the hobbed bolt, but the filament was stuck in the extruder.

Cut the filament off, removed the extruder, heated to 220 and tried to pull the filament back out of the head but no go.

Is there a video or guide to pulling apart the extruder? I dont believe jamming something in would solve the problem at this point.

 

Fixed.

Heated the hot end? up to 225 and waited 15 minutes then got a brand new pair of pliers in there to grip what i could of the old filament, had to pull uncomfortably hard but out it came.

Reassembled the whole thing and back to printing, awesome.
