Hi @sfurnojr
In Laser Tools → Device Settings → Dimensions / Units, try:
Enable Z Axis: on
Relative Z Moves Only: off
OMTech Polar: on
Optimize Z Moves: on
Then make sure you enter the actual material thickness in Cuts/Layers before running the job. Don’t leave Material height at 0 with Z enabled.
Docs for the OMTech Polar setting are here:
This GWeike guide may also be useful, as the Z behavior appears similar:
