Maralb,

The external power supply has to be 30Vdc at 14A. (it is already on order)
Not sure about the controller yet as I haven't finally decided on the application but I am also waiting for Bart's test results of the Retna Engrave board viewtopic.php?f=6&t=270 as this could be really useful.

I use Mach at present and can therefore output the PWM direct with a separate gate just to switch the tickle pulse.
If Bart finds the Retna OK then my options change and I will consider a dedicated DSP.
Alternately I may just build my own PWM with a manual 0 - 100% power adjust which is then Mach triggered like my existing system.
It's early days yet.

Nice. What kind of power out?

I have been keeping my eye on CO2s on ebay but most have been too small, ~25watt max.
