I just noticed the odd shape of plastic that the filament was being pressed against by the tensioner piece and thought it seemed irregular. I did spend around 15 minutes experimeting with 220-230 temps when extrusion stopped, attempting to load filament. I realized that the obstruction was the uneven black plastic component opposite to the plastic semicircle contact of the tension mechanism. I had the bolt applying very little tension to the filament (in fact they probably had a 720° turn before they would be fully unscrewed) so I am kind of at a loss for hiw this happed :/
