Hmmm, looks like a clever idea. I would guess it shows the left side of the kerf. I've always liked the idea of laser alignment. Though, I added a sacrificial fence to my SCMS and the kerf in it perfectly aligns with the left and right sides of the cut. Costs me 3/4" cut width but worth it.

Phil, does your fence have angled cuts as well?

Yes but I don't use it for those. Prefer a miter sled.
