Focal distance set using material library - incorrect distance

Hi I have a gweike cloud RF laser.
I’m new to LightBurn.

I’m trying to setup my material library.
I’ve set the material thickness property’s as such:

I also have light burn configured to control the Z axis.

When I start the cut. The Z axis moves to the material thickness property I have set in the library.
But I would like to add an offset to the this. Or maybe I have something miss configured in my machine.
If I set the material thickness to 6.35mm, I would expect the z axis to move to the z position 10.35mm.
But currently, the Z axis is always moving to what ever the material thickness is set to in the material library in this case 6.35mm.

The machine settings are configured like this:

I tried to adjust the Focus distance parameter, that doesn’t seem to make a difference in this behavior.

You’re the third Gweike user in the last couple of weeks facing issues with Z-axis/focusing.

I almost wonder if Gweike deserves its own section.

In any case, would be good if you can put your heads together on this.

Thanks for linking us up

My work around is to use the material thickness parameter as the focal height settings for Z axis control.
