/**
* Use stallGuard2 to sense an obstacle and trigger an endstop.
* You need to place a wire from the driver's DIAG1 pin to the X/Y endstop pin.
* Use StallGuard2 to sense an obstacle and trigger an endstop.
* Connect the stepper driver's DIAG1 pin to the X/Y endstop pin.
* X, Y, and Z homing will always be done in spreadCycle mode.
*
* X/Y/Z_HOMING_SENSITIVITY is used for tuning the trigger sensitivity.
* X/Y/Z_STALL_SENSITIVITY is used for tuning the trigger sensitivity.
* Higher values make the system LESS sensitive.
* Lower value make the system MORE sensitive.
* Too low values can lead to false positives, while too high values will collide the axis without triggering.
