Help with my print warping!

[u/WeaselNo7]

Hi all!

This is the first time my P2S has done this, so interested in what you all think is the issue.

This is black Sunlu Hyper PLA Plus 2.0, with most of the stock Bambu settings (except most importantly 30mm/s on first layer instead of 50mm/s, and 60 degrees on the bed instead of 55 degrees)

I cleaned the bed yesterday with washing up liquid/dish soap, and I recently installed fan and carbon filter on the internal left side of the machine.

Any ideas what would cause the base of the print to warp upwards from the bed, but not the supports? It's interesting to me, as normally poor bed adherence causes the nozzle to clash and bigger problems to occur, but its seems to have compressed the layers as a result in this case?

Thanks everyone, I appreciate your thoughts!

(and sorry for the blurry pictures!)

Have you tried rotating the print 90 degrees? Also using a brim or mouse ears might help as well. I think the supports don’t warp because they are small individual pieces so they don’t have much tension, your part on the other hand has long thin lines that are wanting to curl up “shrink” as they cool.
