Hi, that is very interesting. I noticed that link on SMTNet 
newsletter this morning too.

I currently have a home-made xy table that I'm using with a CO2 
laser. I'm using PLT files and Dancam software to drive it. The laser 
is fixed and the xy table moves the workpiece around. Maybe I could 
attach a laser diode to do exposure.
