Can the bowden tube get stuck?

Recommended Posts

I had numerous problems where not enough material gets extruded. Either the a plug formed (I think I solved this with owens clamp) or the filament got stuck in the tube. Now I noticed that I cant push the filament through the tube at all. I used to be able to just push it through but suddeny I cant anymore. Could it be that the tube changed its shape?

If you clamp down the 4 mount screws on the head too hard, the tube gets pushed into the peek part too hard, deforms and restricts the filament to a point where it can't get through anymore. if you push it through by hand, you should see and feel where the obstruction is exactly. the same with owens clamp (i think).
