Printing TPU on an Ender 3 V2 (Bowden tube) HELP!

The softer tpus are just begging for trouble, but the stiffer ones aren’t bad.

I don’t recall which extruder version comes on the v2, but my V1 had a lot of open space between the gear and the hole it had to go through. If you have that, too, either upgrade or it fishmouth some ptfe so the filament can’t squish out sideways there.

Beyond that, just go slow and turn the retraction way down. If you have a lot of problems with stringing, maybe faster travel moves and accelerations can help break them, or try cooler temps. I think I was 5C under the recommended settings, but I never checked if that was an accurate temperature. (maybe when i set 190 it was really giving 195 at the nozzle).

Good luck!
