I have a new blue-and-white 100-watt laser from HL Laser, and it came with auto focus. I’m happy to say that it MOSTLY works as intended. When I hit the Focus button it moves up until the limit switch is tripped and backs off slowly. Unfortunately it doesn’t stop there. At a certain point on the downward cycle it switches to rapid move and KEEPS moving downward, FAR out of focal range. I haven’t seen how far it will go since I’ve always stopped it manually, but it’s way too far.
I realize that the downward cycle it arbitrary and determined by the user to allow for different focal lengths, but so far I haven’t been unable to find the settings I need to use to tell the controller where to stop.
I have the RDC6445 controller. Does anyone know where I can find this setting so I can start using the auto-focus feature?
