Filament jams on retract above Bondtech gear?
I'm not sure I understand why this is happening? Does anyone have any ideas? It happens only when printing TPU (filamentum flex fill 98A).
RE: Filament jams on retract above Bondtech gear?
For TPU, you have to back off the tension on the bondtech gears, slow the printer speed way down, and use the right TPU settings in the slicer. There is a good post around here for a TPU or Flex profile and a bunch of "my TPU print went bad" posts. Read em all.
You'll need to make sure your whole pathway is clear of any other materials before starting (do a couple of cold pulls), back off the tension, slow down the print (how does 20mm/s sound) and make a bunch of settings changes , manage your climate etc. Print in TPU or Flex is a way advanced topic.

Thanks!! I'll try your suggestions. Yes, I had set to 15mm/s. You're right, but I'm also desperate to print some more propeller ducts for my Shendrones Squirt drone. I smashed up the ones that came with it haha. I'll spend some time reading.
