Longer Ray 20W Laser Module - Cleaning and Maintenance

[@MICHELDANGAIN]

Hello, thank you for this video. I have a little question. I have the LONGER RAY5 20w, I know that it is designed to go up to 10000mm/minute, but I have a problem, I have the impression that between 6000 and 10000, I don't see any difference of speed. Is there an adjustment to be made? I should point out that I precisely compared to 6000 and 10000, the time is identical... THANK YOU FOR YOUR HELP

Soy de Paraguay. Tengo una longer Ray 5 . Me duplica el grabado. Cuál puede ser la causa ?

Anyone ever figure out to remove lens cover (shown at 2:37 in this video) on a Longer B1 30w? It just doesn’t slip off like in this video and I’m afraid to break it using too much force.
