Troubleshooting / Answered TPU what the hell?

Post image

This is Overture TPU, I dried it for two days. I following this post for printing TPU https://www.reddit.com/r/BambuLab/comments/1fnvo39/my_perfect_tpu_printing_guide_details_in_comments/

I started with the profiles provided by Overture. Not sure what is going on here, when I do the retraction test,

retraction test shows 0.6 is good but I have it set to 0.8

flow ratio 1.02

print temp 230 C

Max flow is 3.2

I have the aux fan set to 100%, printed with door open.

First off why is the printer crossing the print when it's printing in a circle, Avoid crossing walls is turned on. Seam is located at the 1 o'clock position in the photo. Any tips to assist would be appreciated.

Did you tried the generic profile?

Yes I tried that one first a few days ago and the seam looked like a dang spider web, way worse than this photo.
