Hi All,
In a long past posting I said I would test some hard anodized stuff that I had here. I finally got around to it. Hard is definitely the word.
I laughed at my normal anodized settings. I finished up using the same setting as cutting acrylic. Then it removed some serious coating. Hard anodizing can be almost 0.003" thick and the stuff I had here must have been close.
There is a definite depression where the lettering is.
Sorry for taking so long. I am old, I forget stuff.
