You should check the distance from the front and back of the blade to see if it’s the same.
You could put a long straight edge along the side of the blade facing the fence and then measure where the distance from the front edge of the table and the back edge of the table, to the edge of the straight edge. The distance should be the same!

Check your tape measure.

See if you can move your arbor by hand. Is the cut square to the surface referenced on the table? It’s possible that when you turn the saw on, the force pulls on the arbor and kicks the blade out. If that’s the case, it may also be pulling it off square. If that’s the case, it could be a loose bolt, a broken part or just worn out bearings.

I would check the arbor bearings. It sound like you might have and arbor with endplay allowing the blade to move away from the cut under load.

I assume this is sheet goods you are cutting? Is the fence locked tight at the rear and not flexing?

If you just read this, it will tell you (with pictures) of ways you can check your fence-to- blade situation.

He’s a bit technical but this is how I tune my fence.

Thanks so much for the feedback everyone!

Once I get home tonight, I’ll continue to look into it further. An issue with the arbor makes the most sense. Cuts are coming out perfectly square, they’re just a hair too long. If the arbor is being pulled when the motor kicks on, it makes sense that the cut if too long if the blade is being pulled off by a hair.

If the cuts are repeatable it’s unlikely that anything is moving.
Most fences have a sight glass that can be set so measurements between the blade and the fence are not necessary.
When I set the sight glass on the fence I just made a short rip cut and then set the sight glass so it matched the width of the cut.
