Hi guys. I have a voron 24 for over 3 Years now. All fine unless the Bed Level is broken. Ive tried everything. The Bed tilts visually down towards Y 350, but Bed-Mesh shows oposite. My first Layer normally PLA are just holding. But now im with PVA. and the prints gets loose. It seams that Quad Gantry level does not level. Or i assume, Y Axis is somehow inverted when the correction happens. Bed_Mesh makes things worse. Im working with klipper, fluidd, moonraker with a Fystec 1.0 Motorcontroller. Slicer (Cura or Prusa, same Outcome) -When doing a Bed_Mesh calibrate, the outcome is verry similar with a deviation of around 0.16 !!!The Bed is evenly tilted upwards to Y 350!!! -After Quad Gantry Level i can see, that the gantry is not level on Y Axis !!!

What i think could be the Problem.

When Bed_Mesh - changes in Y axis are inverted and make the Problem worse.
Stepper Motors 17hs19 2004S1 do only 0.1mm steps everything in between is rounded up or down.
Bed_Mesh Profile is not used, even when explicit load one
Somewhere is a Mesh profile that loads. I had issues with path finding. Made the path fix mod!

If somebody can help me, would be great. Thanks!

This file contains common pin mappings for the Fysetc Spider board.

To use this config, the firmware should be compiled for the STM32F446.

When calling "menuconfig", enable "extra low-level configuration setup"

and select the "12MHz crystal" as clock reference

For flashing, write the compiled klipper.bin to memory location 0x08000000
