Warping Issues with Tall U-Profile – Need Help

Hi everyone,

I’m having trouble printing a fairly tall U-shaped profile. The issue is that the edges start lifting off the bed during the print, causing the part to warp into a kind of arch—even though the print completes.

I’ve already tried disabling cooling for the first few layers, but it didn’t help.

Has anyone experienced something similar or found a good fix for this? I’d really appreciate any tips or tricks for preventing this kind of warping.

Thanks in advance!

Can you provide some more Information / Pictures? Material, Printer, Plate, …
I don’t have a slicer on this computer …

If you don’t have glue on hand you could try use Brim instead.
