I have a corexy and the configuration is half prepared by RatRig, who owns the kit.
Until now I had never worried about the Ztilt and the BedMesh. But now I am in the process of changing the Zprobe, from an inductive one to a Panda Pi (BdSensor) and I am going to change its location on the Hotend.
First I’ll give you the sections of the configuration that I think are relevant, and then I’ll ask the questions.

1 Doubts in Z TILT calculation
After doing Homing, in my routine I include doing ZTilt.
There are two sections that I see as more important, the section (z_position), I think that I have it clear, it is where the Z axes are joined to the bed, by means of some arms.
(points), this is the one I have the most doubts about, they are the points that…:
a) The printer nozzle moves to these points, to check the Z coordinate, and adjust the TILT of the bed, so in my case, the points that will be considered to adjust the TILT would be [32, 55], [ 207, 365] and [332, 55] (these are the points to adjust the TILT).
b) The printer nozzle moves to those points plus X_offset and Y_offset, to adjust the Z_Tilt, so the points that Klipper uses to adjust the TILT are [60, 60], [235, 370] and [360, 60 ]
2 Doubts in Bed Mesh
The question is similar to the previous one:
In the points that it is calculated that it has to take the height, it is where the nozzle goes down, or where the Z Probe goes down
