check the blade to the fence
and the slot to both
the top could be slightly twisted
from square
and the fence straight with the miter slots

check the adjustment pads on the fence too
they may be old and worn

here is the best i can do for delta parts
enter the model # of your fence
hope this helps

Also, check the fence itself for square; the auxiliary fence I was using was slightly off so I had to adjust for that until I was able to replace it.

Check as above to see if the fence is parallel to the lots and if the blade is also parallel.
Is it more pronounced if the rip is wider or narrower or off by the same? If it changes you may have warped rails. Also check the surfaces of the fence. Lay it on its side on a flat surface and see if maybe your fence body may be warped etc. Next check the pads they may be worn or if you are adjusting by the screws get everything all aligned and put a little lock tight on them so they don’t loosen. Also are you setting your fence so it toes out from the blade? If so maybe you are adjusting it out further than you think and it is more pronounced on longer rips.

You didn’t tell us if it stays aligned for a while and starts doing it again after a couple of cuts or days.

Sounds like the adjustment screws are loose. Put some Loktite on them as mrg said.
