 *
 *
 *   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

//
// EEPROM
//
// The microcontroller can store settings in the EEPROM, e.g. max velocity...
// M500 - stores parameters in EEPROM
// M501 - reads parameters from EEPROM (if you need reset them after you changed them temporarily).
// M502 - reverts to the default "factory settings".  You still need to store them in EEPROM afterwards if you want to.
//define this to enable EEPROM support
//#define EEPROM_SETTINGS

#if ENABLED(EEPROM_SETTINGS)
  // To disable EEPROM Serial responses and decrease program space by ~1700 byte: comment this out:
  #define EEPROM_CHITCHAT // Please keep turned on if you can.
#endif

//
// Host Keepalive
//
// When enabled Marlin will send a busy status message to the host
// every couple of seconds when it can't accept commands.
//
#define HOST_KEEPALIVE_FEATURE        // Disable this if your host doesn't like keepalive messages
#define DEFAULT_KEEPALIVE_INTERVAL 2  // Number of seconds between "busy" messages. Set with M113.

//
// M100 Free Memory Watcher

//
// Nozzle Park -- EXPERIMENTAL
//
// When enabled allows the user to define a special XYZ position, inside the
// machine's topology, to park the nozzle when idle or when receiving the G27
// command.
//
// The "P" paramenter controls what is the action applied to the Z axis:
//    P0: (Default) If current Z-pos is lower than Z-park then the nozzle will
//        be raised to reach Z-park height.
//
//    P1: No matter the current Z-pos, the nozzle will be raised/lowered to
//        reach Z-park height.
//
//    P2: The nozzle height will be raised by Z-park amount but never going over
//        the machine's limit of Z_MAX_POS.

#endif

//
// Clean Nozzle Feature -- EXPERIMENTAL
//
// When enabled allows the user to send G12 to start the nozzle cleaning
// process, the G-Code accepts two parameters:
//   "P" for pattern selection
//   "S" for defining the number of strokes/repetitions
//
// Available list of patterns:
//   P0: This is the default pattern, this process requires a sponge type
//       material at a fixed bed location. S defines "strokes" i.e.
//       back-and-forth movements between the starting and end points.
//
//   P1: This starts a zig-zag pattern between (X0, Y0) and (X1, Y1), "T"
//       defines the number of zig-zag triangles to be done. "S" defines the
//       number of strokes aka one back-and-forth movement. Zig-zags will
//       be performed in whichever dimension is smallest. As an example,
//       sending "G12 P1 S1 T3" will execute:
//
//          --
//         |  (X0, Y1) |     /\        /\        /\     | (X1, Y1)

//         |           |  /      \  /      \  /      \  |
//         |  (X0, Y0) | /        \/        \/        \ | (X1, Y0)

//   P2: This starts a circular pattern with circle with middle in
//       NOZZLE_CLEAN_CIRCLE_MIDDLE radius of R and stroke count of S.
//       Before starting the circle nozzle goes to NOZZLE_CLEAN_START_POINT.

// Increase the FAN PWM frequency. Removes the PWM noise but increases heating in the FET/Arduino
//#define FAST_PWM_FAN

// Use software PWM to drive the fan, as for the heaters. This uses a very low frequency
// which is not as annoying as with the hardware PWM. On the other hand, if this frequency
// is too low, you should also increment SOFT_PWM_SCALE.
//#define FAN_SOFT_PWM

// Incrementing this by 1 will double the software PWM frequency,
// affecting heaters, and the fan if FAN_SOFT_PWM is enabled.
// However, control resolution will be halved for each increment;
// at zero value, there are 128 effective control positions.
#define SOFT_PWM_SCALE 0

// If SOFT_PWM_SCALE is set to a value higher than 0, dithering can
// be used to mitigate the associated resolution loss. If enabled,

// duty cycle is attained.
