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
