Hi Everyone,
I'm trying out my first project on anodized aluminum (from Chewbarka, of course), and I've run into a bit of a problem. I'm only engraving text, and on more than one occasion now, I end up with dark discolorations. I don't know if it's just failing to engrave properly, or if there's something else going on. Anyone see anything like this before?
Thanks,
- Dave
