What software are you using to control the lasers. On some software I believe it is possible to re-assign colour channels. This would mean that you wouldn't have to alter any wiring or connect any lasers together

Quote: "There is a theory which states that if ever, for any reason, anyone discovers what exactly the Universe is for and why it is here it will instantly disappear and be replaced by something even more bizarre and inexplicable. There is another that states that this has already happened.”... Douglas Adams 1952 - 2001
