//====================== PID > Bed Temperature Control ======================

 * PID Bed Heating
 * If this option is enabled set PID constants below.
 * If this option is disabled, bang-bang will be used and BED_LIMIT_SWITCHING will enable hysteresis.
 * The PID frequency will be the same as the extruder PWM.
 * If PID_dT is the default, and correct for the hardware/configuration, that means 7.689Hz,
 * which is fine for driving a square wave into a resistive load and does not significantly
 * impact FET heating. This also works fine on a Fotek SSR-10DA Solid State Relay into a 250W
 * heater. If your configuration is significantly different than this and you don't understand
 * the issues involved, don't use bed PID until someone else verifies that your hardware works.


 * Max Bed Power
 * Applies to all forms of bed control (PID, bang-bang, and bang-bang with hysteresis).
 * When set to any value below 255, enables a form of PWM to the bed that acts like a divider
 * so don't use it unless you are OK with PWM on your bed. (See the comment on enabling PIDTEMPBED)

 * Add M302 to set the minimum extrusion temperature and/or turn
 * cold extrusion prevention on and off.

 * Prevent a single extrusion longer than EXTRUDE_MAXLENGTH.
 * Note: For Bowden Extruders make this large enough to allow load/unload.

//======================== Thermal Runaway Protection =======================

 * Thermal Protection provides additional protection to your printer from damage
 * and fire. Marlin always includes safe min and max temperature ranges which
 * protect against a broken or disconnected thermistor wire.
 * The issue: If a thermistor falls out, it will report the much lower
 * temperature of the air in the room, and the the firmware will keep
 * the heater on.
 * If you get "Thermal Runaway" or "Heating failed" errors the
 * details can be tuned in Configuration_adv.h

 * Endstop Noise Threshold
 * Enable if your probe or endstops falsely trigger due to noise.
 * - Higher values may affect repeatability or accuracy of some bed probes.
 * - To fix noise install a 100nF ceramic capacitor inline with the switch.
 * - This feature is not required for common micro-switches mounted on PCBs
 *   based on the Makerbot design, which already have the 100nF capacitor.

//============================= Z Probe Options =============================
// @section probes

// See http://marlinfw.org/docs/configuration/probes.html

 * Enable this option for a probe connected to the Z Min endstop pin.

 * Define this pin if the probe is not connected to Z_MIN_PIN.
 * If not defined the default pin for the selected MOTHERBOARD
 * will be used. Most of the time the default is what you want.
 *  - The simplest option is to use a free endstop connector.
 *  - Use 5V for powered (usually inductive) sensors.
 *  - RAMPS 1.3/1.4 boards may use the 5V, GND, and Aux4->D32 pin:
 *    - For simple switches connect...
 *      - normally-closed switches to GND and D32.
 *      - normally-open switches to 5V and D32.
//#define Z_MIN_PROBE_PIN 32 // Pin 32 is the RAMPS default

 * Probe Type
 * Allen Key Probes, Servo Probes, Z-Sled Probes, FIX_MOUNTED_PROBE, etc.
 * Activate one of these to use Auto Bed Leveling below.

 * The "Manual Probe" provides a means to do "Auto" Bed Leveling without a probe.
 * Use G29 repeatedly, adjusting the Z height at each point with movement commands
 * or (with LCD_BED_LEVELING) the LCD controller.
//#define MANUAL_PROBE_START_Z 0.2

 * A Fix-Mounted Probe either doesn't deploy or needs manual deployment.
 *   (e.g., an inductive probe or a nozzle-based probe-switch.)

 * Z Servo Probe, such as an endstop switch on a rotating arm.
//#define Z_PROBE_SERVO_NR 0       // Defaults to SERVO 0 connector.
//#define Z_SERVO_ANGLES { 70, 0 } // Z Servo Deploy and Stow angles

 * The BLTouch probe uses a Hall effect sensor and emulates a servo.
#define BLTOUCH

 * Touch-MI Probe by hotends.fr
 * This probe is deployed and activated by moving the X-axis to a magnet at the edge of the bed.
 * By default, the magnet is assumed to be on the left and activated by a home. If the magnet is
 * on the right, enable and set TOUCH_MI_DEPLOY_XPOS to the deploy position.
 *                and a minimum Z_HOMING_HEIGHT of 10.

 * Multiple Probing
 * You may get improved results by probing 2 or more times.
 * With EXTRA_PROBING the more atypical reading(s) will be disregarded.
 * A total of 2 does fast/slow probes with a weighted average.
 * A total of 3 or more adds more slow probes, taking the average.
//#define EXTRA_PROBING    1

 * Z probes require clearance when deploying, stowing, and moving between
 * probe points to avoid hitting the bed and other hardware.
 * Servo-mounted probes require extra space for the arm to rotate.
 * Inductive probes need space to keep from triggering early.
 * Use these settings to specify the distance (mm) to raise the probe (or
 * lower the bed). The values set here apply over and above any (negative)
 * probe Z Offset set with Z_PROBE_OFFSET_FROM_EXTRUDER, M851, or the LCD.
 * Only integer values >= 1 are valid here.
 * Example: `M851 Z-5` with a CLEARANCE of 4  =>  9mm from bed to nozzle.

  //#define PAUSE_PROBE_DEPLOY_WHEN_TRIGGERED // For Manual Deploy Allenkey Probe

 * Enable one or more of the following if probing seems unreliable.
 * Heaters and/or fans can be disabled during probing to minimize electrical
 * noise. A delay can also be added to allow noise and vibration to settle.
 * These options are most useful for the BLTouch probe, but may also improve

 * Bed Skew Compensation
 * This feature corrects for misalignment in the XYZ axes.
 * Take the following steps to get the bed skew in the XY plane:
 *  1. Print a test square (e.g., https://www.thingiverse.com/thing:2563185)
 *  2. For XY_DIAG_AC measure the diagonal A to C
 *  3. For XY_DIAG_BD measure the diagonal B to D
 *  4. For XY_SIDE_AD measure the edge A to D
 * Marlin automatically computes skew factors from these measurements.
 * Skew factors may also be computed and set manually:
 *  - Compute AB     : SQRT(2*AC*AC+2*BD*BD-4*AD*AD)/2
 * If desired, follow the same procedure for XZ and YZ.
 * Use these diagrams for reference:

// 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.
// :[0,1,2,3,4,5,6,7]
#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,
// some of the PWM cycles are stretched so on average the desired
// duty cycle is attained.

// Temperature status LEDs that display the hotend and bed temperature.
// If all hotends, bed temperature, and target temperature are under 54C
// then the BLUE led is on. Otherwise the RED led is on. (1C hysteresis)

 * RGB LED / LED Strip Control
 * Enable support for an RGB LED connected to 5V digital pins, or
 * an RGB Strip connected to MOSFETs controlled by digital pins.
 * Adds the M150 command to set the LED (or LED strip) color.
 * If pins are PWM capable (e.g., 4, 5, 6, 11) then a range of
 * luminance values can be set from 0 to 255.
 * For Neopixel LED an overall brightness parameter is also available.
 * *** CAUTION ***
 *  LED Strips require a MOSFET Chip between PWM lines and LEDs,
 *  as the Arduino cannot handle the current the LEDs will require.
 *  Failure to follow this precaution can destroy your Arduino!
 *  NOTE: A separate 5V power supply is required! The Neopixel LED needs
 *  more current than the Arduino 5V linear regulator can produce.

  //#define NEOPIXEL_BKGD_COLOR { 255, 255, 255, 0 } // R, G, B, W

 * Printer Event LEDs
 * During printing, the LEDs will reflect the printer status:
 *  - Gradually change from blue to violet as the heated bed gets to target temp
 *  - Gradually change from violet to red as the hotend gets to temperature
 *  - Change to white to illuminate work surface
 *  - Change to green once print has finished
 *  - Turn off after the print has finished and the user has pushed a button

 * R/C SERVO support
 * Sponsored by TrinityLabs, Reworked by codexmas

 * Number of servos
 * For some servo-related options NUM_SERVOS will be set automatically.
 * Set this manually if there are extra servos needing manual control.
 * Leave undefined or set to 0 to entirely disable the servo subsystem.
//#define NUM_SERVOS 3 // Servo index starts with 0 for M280 command

// Delay (in milliseconds) before the next move will start, to give the servo time to reach its target angle.
// 300ms is a good value but you can try less delay.
// If the servo can't reach the requested position, increase it.
#define SERVO_DELAY { 300 }

// Only power servos during movement, otherwise leave off to prevent jitter

// Allow servo angle to be edited and saved to EEPROM

 * Thermal Protection provides additional protection to your printer from damage
 * and fire. Marlin always includes safe min and max temperature ranges which
 * protect against a broken or disconnected thermistor wire.
 * The issue: If a thermistor falls out, it will report the much lower
 * temperature of the air in the room, and the the firmware will keep
 * the heater on.
 * The solution: Once the temperature reaches the target, start observing.
 * If the temperature stays too far below the target (hysteresis) for too
 * long (period), the firmware will halt the machine as a safety precaution.

 * The target temperature is set to mintemp+factor*se[steps/sec] and is limited by
 * mintemp and maxtemp. Turn this off by executing M109 without F*
 * Also, if the temperature is set to a value below mintemp, it will not be changed by autotemp.

 * High Temperature Thermistor Support
 * Thermistors able to support high temperature tend to have a hard time getting
 * good readings at room and lower temperatures. This means HEATER_X_RAW_LO_TEMP
 * will probably be caught when the heating element first turns on during the
 * preheating process, which will trigger a min_temp_error as a safety measure
 * and force stop everything.
 * To circumvent this limitation, we allow for a preheat time (during which,
 * min_temp_error won't be triggered) and add a min_temp buffer to handle
 * aberrant readings.
 * If you want to enable this feature for your hotend thermistor(s)
 * uncomment and set values > 0 in the constants below

// The number of consecutive low temperature errors that can occur
// before a min_temp_error is triggered. (Shouldn't be more than 10.)

// The number of milliseconds a hotend will preheat before starting to check
// the temperature. This value should NOT be set to the time it takes the

 * PWM Fan Scaling
 * Define the min/max speeds for PWM fans (as set with M106).
 * With these options the M106 0-255 value range is scaled to a subset
 * to ensure that the fan has enough power to spin, or to run lower
 * current fans with higher current. (e.g., 5V/12V fans with 12V/24V)

 * FAST PWM FAN Settings

 *   These defaults are the same as with the old FAST_PWM_FAN implementation - no migration is required
 *   NOTE: Setting very low frequencies (< 10 Hz) may result in unexpected timer behavior.
 * USE_OCR2A_AS_TOP [undefined by default]
 *   Boards that use TIMER2 for PWM have limitations resulting in only a few possible frequencies on TIMER2:
 *   16MHz MCUs: [62.5KHz, 31.4KHz (default), 7.8KHz, 3.92KHz, 1.95KHz, 977Hz, 488Hz, 244Hz, 60Hz, 122Hz, 30Hz]

 *   A greater range can be achieved by enabling USE_OCR2A_AS_TOP. But note that this option blocks the use of
 *   PWM on pin OC2A. Only use this option if you don't need PWM on 0C2A. (Check your schematic.)
 *   USE_OCR2A_AS_TOP sacrifices duty cycle control resolution to achieve this broader range of frequencies.

 * that should be used for the second endstop. Extra endstops will appear in the output of 'M119'.
 * Use X_DUAL_ENDSTOP_ADJUSTMENT to adjust for mechanical imperfection. After homing both motors

 * Dual X Carriage
 * This setup has two X carriages that can move independently, each with its own hotend.
 * The carriages can be used to print an object with two colors or materials, or in
 * "duplication mode" it can print two identical or X-mirrored objects simultaneously.
 * The inactive carriage is parked automatically to prevent oozing.
 * X1 is the left carriage, X2 the right. They park and home at opposite ends of the X axis.
 * By default the X2 stepper is assigned to the first unused E plug on the board.
 * The following Dual X Carriage modes can be selected with M605 S<mode>:
 *   0 : (FULL_CONTROL) The slicer has full control over both X-carriages and can achieve optimal travel
 *       results as long as it supports dual X-carriages. (M605 S0)
 *   1 : (AUTO_PARK) The firmware automatically parks and unparks the X-carriages on tool-change so
 *       that additional slicer support is not required. (M605 S1)
 *   2 : (DUPLICATION) The firmware moves the second X-carriage and extruder in synchronization with
 *       the first X-carriage and extruder, to print 2 copies of the same object at the same time.
 *       Set the constant X-offset and temperature differential with M605 S2 X[offs] R[deg] and
 *       follow with M605 S2 to initiate duplicated movement.
 *   3 : (MIRRORED) Formbot/Vivedino-inspired mirrored mode in which the second extruder duplicates
 *       the movement of the first except the second extruder is reversed in the X axis.
 *       Set the initial X offset and temperature differential with M605 S2 X[offs] R[deg] and

 * Spindle & Laser control
 * Add the M3, M4, and M5 commands to turn the spindle/laser on and off, and
 * to set spindle speed, spindle direction, and laser power.
 * SuperPid is a router/spindle speed controller used in the CNC milling community.
 * Marlin can be used to turn the spindle on and off. It can also be used to set
 * the spindle speed from 5,000 to 30,000 RPM.
 * You'll need to select a pin for the ON/OFF function and optionally choose a 0-5V
 * hardware PWM pin for the speed control and a pin for the rotation direction.
 * See http://marlinfw.org/docs/configuration/laser_spindle.html for more config details.
  #define SPINDLE_LASER_ACTIVE_HIGH     false  // Set to "true" if the on/off function is active HIGH
  #define SPINDLE_LASER_PWM             true   // Set to "true" if your controller supports setting the speed/power
  #define SPINDLE_LASER_PWM_INVERT      true   // Set to "true" if the speed/power goes up when you want it to go slower
  #define SPINDLE_LASER_POWERUP_DELAY   5000   // (ms) Delay to allow the spindle/laser to come up to speed/power
  #define SPINDLE_LASER_POWERDOWN_DELAY 5000   // (ms) Delay to allow the spindle to stop

    //#define SPINDLE_CHANGE_DIR               // Enable if your spindle controller can change spindle direction
    #define SPINDLE_CHANGE_DIR_STOP            // Enable if the spindle should stop before changing spin direction
    #define SPINDLE_INVERT_DIR          false  // Set to "true" if the spin direction is reversed

     *  The M3 & M4 commands use the following equation to convert PWM duty cycle to speed/power
     *    where PWM duty cycle varies from 0 to 255
     *  set the following for your controller (ALL MUST BE SET)
    #define SPEED_POWER_SLOPE    118.4
    #define SPEED_POWER_MIN     5000
    #define SPEED_POWER_MAX    30000    // SuperPID router controller 0 - 30,000 RPM
    #define SPEED_POWER_SLOPE      0.3922
    #define SPEED_POWER_MIN       10
    #define SPEED_POWER_MAX      100    // 0-100%

 * Coolant Control
 * Add the M7, M8, and M9 commands to turn mist or flood coolant on and off.
 * Note: COOLANT_MIST_PIN and/or COOLANT_FLOOD_PIN must also be defined.
  #define COOLANT_MIST                // Enable if mist coolant is present
  #define COOLANT_FLOOD               // Enable if flood coolant is present
  #define COOLANT_MIST_INVERT  false  // Set "true" if the on/off function is reversed
  #define COOLANT_FLOOD_INVERT false  // Set "true" if the on/off function is reversed

 * Filament Width Sensor
 * Measures the filament width in real-time and adjusts
 * flow rate to compensate for any irregularities.
 * Also allows the measured filament diameter to set the
 * extrusion rate, so the slicer only has to specify the
 * volume.
 * Only a single extruder is supported at this time.
 *  34 RAMPS_14    : Analog input 5 on the AUX2 connector
 *  81 PRINTRBOARD : Analog input 2 on the Exp1 connector (version B,C,D,E)
 * 301 RAMBO       : Analog input 3
 * Note: May require analog pins to be defined for other boards.

  #define FILAMENT_SENSOR_EXTRUDER_NUM 0    // Index of the extruder that has the filament sensor. :[0,1,2,3,4]
  #define MEASUREMENT_DELAY_CM        14    // (cm) The distance from the filament sensor to the melting chamber

  #define FILWIDTH_ERROR_MARGIN        1.0  // (mm) If a measurement differs too much from nominal width ignore it
  #define MAX_MEASUREMENT_DELAY       20    // (bytes) Buffer size for stored measurements (1 byte per cm). Must be larger than MEASUREMENT_DELAY_CM.

  #define DEFAULT_MEASURED_FILAMENT_DIA DEFAULT_NOMINAL_FILAMENT_DIA // Set measured to nominal initially

  // Display filament width on the LCD status line. Status messages will expire after 5 seconds.

 * CNC Coordinate Systems
 * Enables G53 and G54-G59.3 commands to select coordinate systems
 * and G92.1 to reset the workspace to native machine space.

 * Auto-report temperatures with M155 S<seconds>

 * Include capabilities in M115 output

 * Expected Printer Check
 * Add the M16 G-code to compare a string to the MACHINE_NAME.
 * M16 with a non-matching string causes the printer to halt.

 * Disable all Volumetric extrusion options

   * Volumetric extrusion default state
   * Activate to make volumetric extrusion the default method,
   * with DEFAULT_NOMINAL_FILAMENT_DIA as the default diameter.
   * M200 D0 to disable, M200 Dn to set a new diameter.

 * Enable this option for a leaner build of Marlin that removes all
 * workspace offsets, simplifying coordinate transformations, leveling, etc.
 *  - M206 and M428 are disabled.
 *  - G92 will revert to its behavior from Marlin 1.0.

 * Set the number of proportional font spaces required to fill up a typical character space.
 * This can help to better align the output of commands like `G29 O` Mesh Output.
 * For clients that use a fixed-width font (like OctoPrint), leave this set to 1.0.
 * Otherwise, adjust according to your client and font.

 * Spend 28 bytes of SRAM to optimize the GCode parser

 * CNC G-code options
 * Support CNC-style G-code dialects used by laser cutters, drawing machine cams, etc.
 * Note that G0 feedrates should be used with care for 3D printing (if used at all).
 * High feedrates may cause ringing and harm print quality.
//#define PAREN_COMMENTS      // Support for parentheses-delimited comments
//#define GCODE_MOTION_MODES  // Remember the motion mode (G0 G1 G2 G3 G5 G38.X) and apply for X Y Z E F, etc.

// Enable and set a (default) feedrate for all G0 moves
//#define G0_FEEDRATE 3000 // (mm/m)
#ifdef G0_FEEDRATE
  //#define VARIABLE_G0_FEEDRATE // The G0 feedrate is set by F in G0 motion mode

 * Startup commands
 * Execute certain G-code commands immediately after power-on.
//#define STARTUP_COMMANDS "M17 Z"

 * G-code Macros
 * Add G-codes M810-M819 to define and run G-code macros.
 * Macros are not saved to EEPROM.
//#define GCODE_MACROS
  #define GCODE_MACROS_SLOTS       5  // Up to 10 may be used
  #define GCODE_MACROS_SLOT_SIZE  50  // Maximum length of a single macro

 * User-defined menu items that execute custom GCode
  //#define CUSTOM_USER_MENU_TITLE "Custom Commands"
  #define USER_SCRIPT_DONE "M117 User Script Done"
  //#define USER_SCRIPT_RETURN  // Return to status screen after a script

  #define USER_DESC_5 "Home & Info"
  #define USER_GCODE_5 "G28\nM503"

 * Host Action Commands
 * Define host streamer action commands in compliance with the standard.
 * See https://reprap.org/wiki/G-code#Action_commands
 * Common commands ........ poweroff, pause, paused, resume, resumed, cancel
 * G29_RETRY_AND_RECOVER .. probe_rewipe, probe_failed
 * Some features add reason codes to extend these commands.
 * Host Prompt Support enables Marlin to use the host for user prompts so
 * filament runout and other processes can be managed from the host side.
