Seeking recommended settings for anodized aluminum in Materials Test Generator

I have a 20W Galvo Fiber Laser and I could use some guidance on settings in the Materials Test Generator for engraving anodized aluminum.

I have gone through all the lens focal length on correction steps, but I’m at a bit of a loss on where to start with the settings for the materials test. Any help is appreciated.
