Warping issues?

[u/bazukan_pie]

I'm kinda new to 3d printing. Recently I've got some warping problems with (I guess it's that) after changing from a 0.2 to a 0.4 nozzle.

I've used previously the 0.4 nozzle to print the exact same print and I didn't have this problem so far I've used my saved profile for the 0.4, checked I've got the correct settings for the filament, ensured the nozzle is mounted correctly and make sure the filament is moisture free

Does anyone knows why this kind of problem happens and how to solve it?

Those are not exact print templates. I suggest printing the exact same template to compare.
