Aluminum Settings?

[Aaron Reimer]

Now that I've got the laser running, I tried burning some samples I got of anodized dog tags. I'm having trouble finding good settings that come clear and don't burn right through to the metal when they supposedly burn bright white. Any advice?

Also, I have a friend that wants me to do his ipod, but the tags are getting pretty hot and I don't want to fry it. Any suggestions on that?

Thanks for the help!
