Set up a pattern to run through QS and click "enable laser output". Then try all combinations switches until the pattern is displayed. I can't remember exactly but it seemed like on of my switches was backwards. Or maybe I'm just lysdexic???
On my setup (only green at the moment), the +G and -G are hooked up to the ILDA board.
Also, just check to make sure you have the screw dust covers taken off the end of your lasers. (Yes, I've left mine on before and couldn't figure out why the hell it wasn't working.)
