I purchased a red CloudRay E Series laser head (through AliBaba) to replace the stock unit on my red-and-black Chinese 80W laser.
It looks like the installation should be fairly simple, but I wonder if there are any instructions, tips, or tricks for installing and alignment.
ALSO: I want to purchase a 1.5inch (38.1mm) lens. I believe all of the other lenses are supposed to be 20 mm to fit into the tube – but I think I heard somewhere that a 38.1 mm lens simply goes in behind the nozzle and is only 18 mm.
Does that sound right?
