Laser Engraving on My Kossel Clone/ Expanding My Build Area

First link doesn't list any power requirements. The second lists power requirements, but mentions "pulsed light" with no mention of duty cycle. And the last lists a 75% duty cycle. They also have a range of frequency output, which will change how it works on various materials (some absorb IR well, some don't). Not sure which one I'd go with.

Given you're looking at less than 2.5V, might have to work out an adapter circuit for the 12V MOSFET drivers off of the RAMPS board, or use the output to drive a 12V relay controlling the adapter that comes with it. Lots of options.
