I was trying to figure out how to engrave in a pocket. Made a simple test file with 2 layers. #1 z-offset is .85, #2 z-offset is 0. I click on Start, layer 1 burns without moving the bed, then the bed is lowered, then layer 2 is burned. I realize that I should have had the z-offset at -.85, but the wrong layer is being offset.
Disabled layer 2 so only the offset layer will run, click Start, burns the layer, lowers the bed, ends and homes.
