Do you have the bracing kit or quick swap? That changes the height of the bed (though shouldn’t change the focus height).
Try homing, then typing G92 X0 Y354 then run the box.
Got it to work! I had the y reversed. I dialed in the machine 0. Now I’ve got to figure out how to square the bed with the laser. I’m looking at your Laser Square 3D print item.
Glad to hear you got it working.
