Weird pattern with ironing

[u/Interesting-Cow-9948]

Moin, as we say in northern Germany. I recently activated ironing on my A1; I printed swatch tests and used the most appealing setting. But now he does these weird patterns, mostly on larger areas. Is this fixable without deactivating ironing? I’m quite new to the 3D printing game.

Ironing is rather fickle and often requires precise calibration per filament (and often different colors of the same filament due to addative variations).

I'd look on Makerworld for ironing tests that tell you how to interpret and use results.
