E3Elite6 ptfe liner slipping out

[3DPBuser]

Anyone have this problem, where the ptfe liner slips up and out during retractions? The little black ring/collet is supposed to keep the liner down and in place, but the liner slips up through it anyway.

Mine works fine.

Well the solution was to melt the top part of the passage closed where the liner goes though, then drill a hole just big enough for the filament only. This keeps the liner down.

You could probably replace the Bowden coupling.

Well I did already order some, but this was after I figured how to seal the top of the passage. Nevertheless, the coupling I had was new, and was not doing the job, so I'm not sure another new one would be better.
