Most pads are ok - perhaps a bit large.
- Change the pad clearance in KiCAD
- File -> Board Setup -> Solder Mask Paste
- "Solder paste absolute clearance" -> -0.09mm
- Configure Light burn to engrave at
- 100mm/s at 28%
- Line interval of 0.02mm
I like to soak a piece of paper in water and put it below the mylar. This helps reduce burning and warping
