Can you clarify what you mean when you say your laser won’t focus? I don’t know your model of laser well enough to know if you need to adjust its focus by hand, or it has a controllable Z axis.
If the focus is adjustable by hand, there is nothing LightBurn could do to affect its ability to focus.
If it has a controllable Z axis, what are you seeing? Is LightBurn not moving the Z axis to the correct height, or not moving it at all?
