*SOLVED* Help with anodized and powder coated aluminum

The other day I read .25" defocus to .433 …then today I read a different one, .125 to .03. I don’t see any rhyme nor reason to it, but if there is I sure would appreciate hearing what it is. And these numbers were both with acrylic.

This was where I was first reading;

@davidgal2 It was .25" so I had to set it to .433". Worked better than I thought it would!
