- *   - Otherwise connect:

- *   PIN OPTIONS\SETUP FOR Z PROBES
- *
- *
- *   WARNING:
- *   Setting the wrong pin may have unexpected and potentially disastrous consequences.
- *   Use with caution and do your homework.
- *
- *
- *   All Z PROBE pin options are configured by defining (or not defining)
- *   the following five items:
- *       Z_MIN_PROBE_ENDSTOP – defined below
- *       Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN – defined below
- *       Z_MIN_PIN - defined in the pins_YOUR_BOARD.h file
- *       Z_MIN_PROBE_PIN - defined in the pins_YOUR_BOARD.h file
- *
- *   If you're using a probe then you need to tell Marlin which pin to use as
- *   the Z MIN ENDSTOP.  Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN determines if the
- *   Z_MIN_PIN or if the Z_MIN_PROBE_PIN is used.
- *
- *   The pin selected for the probe is ONLY checked during probing operations.
- *   If you want to use the Z_MIN_PIN as an endstop AND you want to have a Z PROBE
- *   then you’ll need to use the Z_MIN_PROBE_PIN option.
- *
- *   Z_MIN_PROBE_ENDSTOP also needs to be enabled if you want to use Z_MIN_PROBE_PIN.
- *
- *   The settings needed to use the Z_MIN_PROBE_PIN are:
- *       1. select the type of probe you're using
- *       2. define Z_MIN_PROBE_PIN in your pins_YOUR_BOARD.h file
- *       3. disable Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN
- *       4. enable Z_MIN_PROBE_ENDSTOP
- *   NOTE – if Z_MIN_PIN is defined then it’ll be checked during all moves in the
- *          negative Z direction.
- *
- *   The settings needed to use the Z_MIN_PIN are:
- *       1. select the type of probe you're using
- *       2. enable Z_MIN _PIN in your pins_YOUR_BOARD.h file
- *       3. enable Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN
- *       4. disable Z_MIN_PROBE_ENDSTOP
- *   NOTES – if Z_MIN_PROBE_PIN is defined in the pins_YOUR_BOARD.h file then it’ll be
- *          ignored by Marlin
