Help with surfacing

Why is it when i am trying to plane a board with aramana 1.125 " surfacing bit it leaves ridges?

I would say your z axes is not tramed with your wasteboard. In other words the z axes is not square is leaning one way or another.

Yeah, what Wayne said.

If your router isnt exactly perpendicular to the material one side of the cutter will ride lower than the other => ridges. You can gauge the direction of tilt by feeling the ridges, the ridge “steep” side is your low point.
