If you are using sensorless homing, and have your own X and/or Y homing macros, you can use override the klicky macros behavior with your very own _HOME_X and _HOME_Y macros. The Klipper code will detect the overshoot and account for it in its calculations. When setting up sensorless homing it was required to create a homing. (So, in future homing operations, Klipper will obtain the same position even if the endstop triggers a little earlier or a little later. However, this is a problem (Z_SAFE_HOME) when the bed is at the full extent of travel. TmcDiagPins = { PG_6, PG_9 } in your board. Stepper motor overshoot should not adversely impact the precision of the homing and probing procedure. Make sure that none of the X, Y, or Z endstops are being pressed.
