[sdiy] Laser etching powder coated aluminum

[Cary Roberts]

>Can you provide some details of the laser you used?

Epilog Helix 24.  Techshop says 45 watts but Epilog doesn't sell a unit that
size.  Possibly 50?  I've seen a power meter on the unit immediately
following a laser replacement and it registered 38w so I'm not sure I trust
Epilogs power ratings.

Material was ran at 600dpi, 90% power, and 50% speed.  That data is only
meaningful if you have an Epilog of the same model and tube size.
