Hybrid table not parallel with gantry in Y axis travel

[GSP (Jacques Webster-Curley)]

I was installing the tiling fence from the Cut Rocket library last night, and when I went to surface the front of the tiling fence as recommended, I zeroed the Z to the hybrid table and just toughed the bit to the tiling fence and ran it from the SW to the NW position. As it ran, I noticed that the hybrid table actually rises up 0.095", which kind or surprised me that it was so much.

So I was going to run the slab flattening file, but is there something I missed when setting my S5Pro 4x4 up (I found nothing in the manual related to this)? I realize I need to see what the difference in heights of the hybrid table are at the SE, C and SW positions. When I looked at the aluminum cross frame member that join the left and right sides, they are all sitting flush to the table I built. Any suggestions? Or do I just go for it and resurface?

Just resurface it.

Mdf has a lot more thickness variation than everyone thinks.

Agree with Quicky06.

Even most S2S/S4S milled lumber can deviate more than that.

I took off .about .125” to get mine flat. Table flat level, aluminum T-track dead level across all axis. Not so much when the spoil boards were installed. Some were starting to curve on their own when removed from the packaging. Normal for material to change with exposure to different moisture environments.
