Peaks and Valleys in Bed Mesh

It’s an Ender 3 S1 Pro so it has a BL touch sensor. Honestly it doesn’t seem that bad to me, just weird it’s so uniform however the bed mesh is not fully compensating. I get sections of under extrusion and over extrusion all over the first layer.

@jakep_82 I’m new to 3D printing so I don’t fully grasp what you are saying. Do you mean the x axis wheels (or perhaps the bracket) may be causing this?

I found another thread where all the comments are suspiciously similar to the issues I’m having. I’m going to spend some time working through that thread when I have a moment to see if anything in there helps.
