//============================= Z Probe Options =============================

// Enable Z_MIN_PROBE_ENDSTOP to use _both_ a Z Probe and a Z-min-endstop on the same machine.
// With this option the Z_MIN_PROBE_PIN will only be used for probing, never for homing.
//
// *** PLEASE READ ALL INSTRUCTIONS BELOW FOR SAFETY! ***
//
// To continue using the Z-min-endstop for homing, be sure to disable Z_SAFE_HOMING.
// Example: To park the head outside the bed area when homing with G28.
//
// To use a separate Z probe, your board must define a Z_MIN_PROBE_PIN.
//
// For a servo-based Z probe, you must set up servo support below, including
// NUM_SERVOS, Z_ENDSTOP_SERVO_NR and SERVO_ENDSTOP_ANGLES.
//
// - RAMPS 1.3/1.4 boards may be able to use the 5V, GND, and Aux4->D32 pin.
// - Use 5V for powered (usu. inductive) sensors.
// - Otherwise connect:
//   - normally-closed switches to GND and D32.
//   - normally-open switches to 5V and D32.
//
// Normally-closed switches are advised and are the default.
//
// The Z_MIN_PROBE_PIN sets the Arduino pin to use. (See your board's pins file.)
// Since the RAMPS Aux4->D32 pin maps directly to the Arduino D32 pin, D32 is the
// default pin for all RAMPS-based boards. Some other boards map differently.
// To set or change the pin for your board, edit the appropriate pins_XXXXX.h file.
//
// WARNING:
// Setting the wrong pin may have unexpected and potentially disastrous consequences.
// Use with caution and do your homework.
//
//#define Z_MIN_PROBE_ENDSTOP
