The machine settings tab is not there when I open Edit. I need to match the dimensions of box from lightburn and my fiber laser
Do you mean setting up your work area. Is this new machine your setting up?
If you set the device up and used the supplied markcfg7 file, this has been taken care of.
The coverage is related to the lens. Did you purchase a new lens?
It’s in the edit → device settings or the icon
It would help us if we knew where and what the problem you are trying to solve is, why do you need to change anything?
The size I select in lightburn doesn’t match the lasered size. I searched for solutions but I don’t have the machine settings tab in edit
Did you set it up using the Lightburn setup in the documentation?
