    Hiya.

    I accidently hit the retract button in Octoprint while it was set to, I think, about 20mm.
    So I guess it has retracted the molten filament into the gears, and now it's completely stuck.

    I can't manually turn the gears even a nanometer, and the tension-thing is completely stuck.

    I figure the only way to fix this is to remove the filament in the gear, but I can't even remove the gear.
    So I guess I have to heat the filament so it can be removed.

    But I'm afraid I'll damage something internally if I heat it too much, e.g. the tension-thing appears to be plastic.

    Suggestions? Max temperature I can try to heat the gears to?

    Figured it out: Turns out the tension-thing could be removed and the drive gear as well. Got it all out and all peachy!
    But now the motor won't turn, so back to searching.

    I'm at the same stage in my dissasembly for what I expect to be a similar jam (different root cause). How did you get the tension arm out? For me it's blocked by the drive gear
