Flexystruder too tight for filament

General LulzBot TAZ

I’ve been trying to use ninja flex on my Flexystruder, but it just doesn’t seems to fit, any 3mm filament won’t fit into this extruder, this has been a problem since day one, when I installed the brand new Flexydual, on my TAZ 5.

When I look into the extruder cavity, the dented cylinder it’s blocking half of the way.

I disassembled the extruder to see if something was wrong.

I couldn’t find any reason why the filament it’s being blocked.

without the cylinder you can see through the cavity.

Any insights of what may be happening?

Make sure the “dent” section of the hobbed bolt lines up with the hole correctly. You may need to play with washer positions and thickness to get it right.
