Is this still the preferred postprocessor to use for Fusion with a laser on OG OnefinityCNC?

I tried it over the weekend but the laser power “rpms” 0-1000 don’t seem to work correctly like they do in G-code generated in my Lightburn trial version. With this postprocessor Fusion seems to output negative numbers for rpm.

Anybody use Fusion with a laser and have any expertise to offer?

Thanks!
