    Have the Lite6 on a Wades, and almost immediately the liner slips upwards 2 to 5 mm, of course causing a jam.

    The little black ring/collet is supposed to keep the liner in place, but obviously the liner is pulling up anyway. Everything is new, never been used.

    How to keep the liner in place?

    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.

    That does look handy, however even when the clip is up, the liner still slides easily out of it.

    How much retraction are you doing?

    It never got printing because of it. But now, I do about 2mm.

    Might be worth replacing the PTFE if it's not gripping properly. I've never experienced this

    Maybe what is was, was that the liner was sticking out the bottom past the heat sink about 1 mm so that I could compress the nozzle onto it. Now I know that you should not do this because the liner bulges. But when the nozzle compressed it, it probably also pushed the liner upwards, which would be backwards through the collet, which probably would have weakened/broken the little metal teeth in the collet. So it probably was not working after that and thus it slipped.

    I did replace the liner, with no extra length out the bottom. Same collet though, because I did not have new ones yes. Is printing fine, but because the liner is still held in the top by my melting/shaping of the top of the passage.
