Laser not turning off when crossing white space

I am using a 15w laser, previously I was using a 4w laser. Using the same Marlin configuration for both. While using the cut feature the laser is not turning off when traversing the white space. The traverse lines are being burnt into the wood. The scan feature works fine, the laser shut down as it crosses the white space. Looked at the gcode and can’t find anything that sticks out. Anyone ever experience this? Is there an option in LB to use M107 to turn off the laser?

Which version of LightBurn are you using? It should be doing this already, and 0.8.07 fixed a bug with this on Marlin specifically.

Had an old version of LB. Upgraded and it works fine.

Thanks for your help.
