Probably, not sure yet, but the last two large prints, a while ago, didn’t have these issues anymore after some changes I’ve made.
At first, like 2-3 months ago, I had big problems with large objects having their corners lifting up. Some of them were curved at some point and made me think it might be the uneven heat distribution or something, not just adhesion.
First noticeable thing I’ve seen after a manual bed tramming (instructions here A1 Bed Tramming | Bambu Lab Wiki). The bed wasn’t leveled, the nozzle was hitting the bed in some part and there was a gap in another part when I did the manual leveling test (custom g-code on that wiki). This manual bed leveling solved a lot of issues.
Another thing I’ve noticed is that the textured plate doesn’t clean up so easily. I guess it depends on the filament and other things but there are small leftover particles you can still see on the plate after some regular wash. Really hot water and something more abrasive than a regular sponge, with soap, did wash it nicely. This was another improvement.
Then the last thing I did was to put aux fan to 0 in all my filament settings, also rising up the speed (to almost max) for the part fan cooling (not for all filaments but many). The rest is left to default… 65 for bed, 220 for regular pla, 225 for silk, and so far so good. This was the last change that made some improvements overall. Turning off AUX fan alone was more important, the rest is up for testing.
I also calibrated every filament I have (flow ratio, PA and volumetric speed, basically these 3 tests) using the tests from Orca) then saved in Bambu. These might be of no influence for the warping prints, but it did improve other things, like details in my prints.
There is no sure answer, you have to test everything. Even draft can affect your prints. I know it did for mine. Every time I opened a window, my prints had issues. So I guess I need to design some kind of enclosure to avoid any outside air currents or changes in temperature.
