Laser focus during camera alignment

I’m using a GweikeCloud Pro and trying to use the LightBurn camera alignment.
When the system creates the reference pattern into a piece of material, I don’t seem to be able to use the correct focus distance on the laser. I’ve tried setting the material thickness on the alignment dialog but that doesn’t seem to have any effect. The result is that the reference target has quite thick lines which makes it hard to complete the alignment accurately. Does anyone have any suggestions?

Do you have the Z axis enabled in your ‘Device Settings’? Try enabling the Z axis and ‘Relative Z moves only’, setting the focus ahead of time (you can adjust the Z position in the Move window), and not adjusting the material thickness setting in the alignment dialog.
