Broken Filament Stuck In The Bowden Tube Going To The Extruder

I have a small broken-off piece of filament stuck in the Bowden tube that goes to the extruder and I can’t seem to get the Bowden tube out of the extruder, can anyone explain the procedure to remove the Bowden tube?

Have you checked the wiki?

I also found this tool pretty helpful if you have another printer to print it.


There was something wrong with the WIKI, no matter what I put in the search box it just came up with a random page, I have that tool but in another format, it has the bowden release on one end and the AMS plug release on the other, I forgot all about it, thanks, I got the Bowden out and the broken filament, now I cant get the nozzle to go back in, it just wont push up.

Can you see through the extruder from the top, and if there is a piece of filament still stuck in there? Carefully pushing a small Allen key in from the top may dislodge an obstruction.

Same from the bottom - a cell phone camera pointing upwards may help. Is there a blob of anything molten? If so, somewhere in the Wiki there is a description of how to heat a small Allen key with a ball-end using a lighter to extract filament from the hotend - a similar exercise may help slowly soften a blob, then let it cool around the Allen key ball, and pull bits out piece by piece.

Check that the top of the nozzle’s diameter isn’t enlarged from molten filament too.

I turned out to be a small piece of broken filament in the Bowden and the extruder.
