    Has anyone else been trying to print with TPU and had success? I have been trying to print a rather long print(20 hours) with Hatchbox TPU and I cant get it to print past the 3 hour mark without jamming. I have tried changing temps both raising it and lowering it, and have had no luck.

    Anyone have ideas on how to make it work better?

    how slow are you printing at? Flexibles need slow... really slow.

    I'm currently running at 50mm/s because that was the recommended setting

    this is what the settings for cura are when I just set print speed
    print speed: 50
    infill:50
    top/bottom:30
    initial:15

    Yea, about that :)
    Cut that down a lot and see where you can get a win.

    Some printers I have to go as slow as 15-20

    Flexibles are tricky (actually some of them like NinjaFlex are a royal pain, the others like SemiFlex are just tricky)

    Yes they are, I've gone through semiflex, Cheetah, and was hoping the stiffer Hatchbox tpu would work better than it has so far

    We like Cheetah (the filament formerly known as SemiFlex) It is easy to use and really quite flexible.

    I never exceed 30mm/s (even with a titan) when printing TPU. Its not worth the risk. I tend to stick down near 15-20. Takes forever but the end result is worth it.
