Blade tilt? Because the indicator says you are cutting 90, doesn’t mean it is. That little screw on the cursor is to adjust it when you bring it to true 90. Check very carefully to see what the plate on the blade says, with a known good square. Stay off any teeth, they will throw you off.

Finally I measure the fence and it s not dead straight. It bows away from the blade about .005” then 6” later bows in toward the blade by .002, and then back out to .005” where I had set it. Could this be causing the problem?

I don’t think that is your burn, however it could be. Check the tilt, if it is dead nutz 90* then make a sacrificial fence to mount, shim it so it is dead true. Your saws ability to cut square requires what you already described, plus a flat table, and flat fence to run against. A wobbly cut is not good, but worst if you are pinching the work against fence, and blade, that is high kickback potential, that isn’t good.

That noting the problem just with a Forrest blade, is something also. Lazyman offered the suggestion to check your blade width, versus your splitter width. Make sure to do that. A Forrest has a pretty robust saw plate. If your splitter width isn’t adequate for it, that could be problematic. If you have calipers measuring both the saw plate, and the splitter could tell you a lot.

Whatever you have isn’t a lot, or the entire side of the cut would be marked.
