From Laser Steve's Thread: "Great way for smear free optics cleaning":
Is this a new discovery? Before I start drilling/tapping I need to know the layout. I always thought the green was farthest from the galvos, then red, then blue. But now I'm hearing some people going with red as being last (closest to the galvos) blue in the middle, and of course green being the one to pass thru the most optics (the green didnt change, for obvious reasons). Any advice, anyone?Then i redesigned it 1st with green,then mixing blue,then mixing red last.
wow!! what a difference.
