V-Core 3 Mesh Problem

Hi, maybe someone here has a tip for me my bed mesh is very crooked i watched the video on youtube which is the best thing to do for me, point C is way too high, so I pushed point B down as far as I could It didn't get much better then I loosened all rails X, Y, Z and gantry, aligned and screwed them back together, but the result is not good The first picture shows how it was before, the second after the adjustment attempt

I might be wrong, but you did z-tilt after adjustments?

Are you sure? I’d expect to see some points at the minimum height in the second picture, but I don’t see anything below ~0.3

Yes, I always do a homing first, then z-tilt and then the mesh here is today's mesh in the first picture, cold condition in the second picture, after 30 minutes of heating at 100°

I'd kill for my mesh to be that flat. It mapped it to compensate for it, that's the process doing its thing. I'm new to VC3, but my total variance is 0.6 and first layer is fine everywhere. I take that back. I was wrong, wrong, couldn't be more wrong. The bed mesh is great for compensation of the first layer. It will work fine in doing so, even with large deviations across the surface. However, when it comes to then printing TALL objects the inconsistency of bed surface will result in Z shift as the compensation impacts greater with height! I ordered an engineering square and will be attempting to resolve mine, with apparently a rubber mallet. That doesn't seem right, but I don't have a better plan.
