Snapmaker Image Inverting

Go to Edit > Device Settings and change the S-Value Max to 254 (or lower) and that will reduce the S parameter output. It’s possible that SnapMaker has a different range than expected.

This fixed my problem. I also used a curve filter to brighten the blacks but I think changing the S-Value did the trick. I changed mine to 235 just to be safe.
