TPU Does not work keeps getting jammed

[Orangeforceone]

After I do the load function it comes out nice. But as soon as I start the print it gets jammed.

Is there a way to adjust the spring tension?

I have the Same Problem with TPU.

I struggle a lot with TPU

It loads nicely, prints some straight lines and then gets jammed.

I reduced the flow speed to 80%, no improvement.

Could someone successfully print TPU with the Artisan? If yes, what settings did you use? I’m running out of ideas.

Hi all,

Had the same problem here. Tried a higher hotend temperature and got good results.
Now printing at 250 degrees Celsius and 30mm/s. works great.

I hope this helps.
Kind regards.

Thanks for the tip. I also noticed the spool puts a lot of unnecessary tension on the filament which will stretch TPU to a smaller diameter. I’m creating a spool adapter with bearings to see it helps. I’m basing it off a snapmaker 2.0 example w/I bearings.
