Hello all,
I have a cloud ray 50w fiber with a f=420mm lens for a 300mmx300mm working area. When I first purchased the laser I adjust the focus by burning steel and adjusting the height until optimum burning based on a YouTube video I watched. I’ve recently noticed after 3d printing a 420mm focal stick that my current focal height is higher than the 420mm focal stick but if I try to burn at the focal stick height it is clearly out of focus. Any help with this or just telling me I have no idea what I’m talking about would be greatly appreciated.
The photo is the difference between currently burning focal height and the bottom of the focal stick.
