I am right on the edge of making my first cut. I'm using the engrave wizard just to give me some gcode. When I run it, it seems to run the z axis backwards. When I jog minus is down, plus is up so jog controls work that way so I though I had eliminated everything else, but it looks like the engrave is cutting air after driving down hard once.
I'm sure I'm doing something dumb which is why I used the wizard -- to eliminate me as an error source. I attached the screenshot, please point out my error.

I think your Feed Height should not be negative.
Also appears that the Z-Depth does not need to be Neg., the SW must assume that it is neg. because a pos. entry does go down into the material.

Thanks, that confirms what I am seeing. I made it all positive numbers and that worked as I wanted.
