Lots of stringing but as I understand that’s normal for TPU. Printed at 225⁰C on a 30⁰ bed, stock Ender 3 S1. 0 retraction, 0.93 flow, 35mm/s for most speeds

    Erm, it’s proper etiquette when posting TPU benchies to upload a picture in squished form 😉

    Pretty decent looking print. This printer has a Bowden tube setup yeah? Impressive. If you decide to upgrade to a direct drive you’ll probably be able to print it with retraction and help tone down the stringiness.

      No the S1 is direct drive. I tried a retraction tower to little effect but perhaps I’ll try a wider range.

      This one I accidentally printed with too many walls to squish much lol. I did another with one wall and no infill, came out the same appearance wise but squishes nicely.

        On my direct drive Voron I could make it through retraction tower test prints fine with TPU, but it would always jam with retraction enabled on longer prints with my usual 0.3mm. Pulling apart the extruder would always reveal some TPU had gotten wrapped around the drive gear. Rather than try tuning until the failure went away, I just went with 0 lol.
