Ok, So it’s not aluminum but it will be when I find the right size plate….
For now I know the NC file is good and it scans from 2 feet away without a problem.
I found a scrap of aluminum to test with….
And before you know it I’m well on my way to a serial number plate….
I’ll wash it with paint like the others
Brass is another good choice especially for something like a custom logo’d wax envelope seal but who does that anymore….. Maybe I will .
