* Marlin allows you to add a custom boot image for Graphical LCDs.
* With this option Marlin will first show your custom screen followed
* by the standard Marlin logo with version number and web URL.
* We encourage you to take advantage of this new feature and we also
* respectfully request that you retain the unmodified Marlin boot screen.
// Enable to show the bitmap in Marlin/_Bootscreen.h on startup.

* 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.

//======================== 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 Filter
* Enable this option if endstops falsely trigger due to noise.
* NOTE: Enabling this feature means adds an error of +/-0.2mm, so homing
* will end up at a slightly different position on each G28. This will also
* reduce accuracy of some bed probes.
* For mechanical switches, the better approach to reduce noise is to install
* a 100 nanofarads ceramic capacitor in parallel with the switch, making it
* essentially noise-proof without sacrificing accuracy.
* This option also increases MCU load when endstops or the probe are enabled.
* So this is not recommended. USE AT YOUR OWN RISK.
* (This feature is not required for common micro-switches mounted on PCBs
* based on the Makerbot design, since they already include the 100nF capacitor.)

//============================= Z Probe Options =============================
// @section probes
// See
* Enable this option for a probe connected to the Z Min endstop pin.
* Enable this option for a probe connected to any pin except Z-Min.
* (By default Marlin assumes the Z-Max endstop pin.)
* To use a custom Z Probe pin, set Z_MIN_PROBE_PIN below.
* - 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.
* WARNING: Setting the wrong pin may have unexpected and potentially
* disastrous consequences. Use with caution and do your homework.
* Probe Type
* Allen Key Probes, Servo Probes, Z-Sled Probes, FIX_MOUNTED_PROBE, etc.
* Activate one of these to use Auto Bed Leveling below.

// 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,
// 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_BRIGHTNESS 127 // Initial brightness (0-255)
//#define NEOPIXEL_STARTUP_TEST // Cycle through colors at startup
* 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.

* 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.
* If you get false positives for "Thermal Runaway", increase
#define THERMAL_PROTECTION_HYSTERESIS 10 // Degrees Celsius
* Whenever an M104, M109, or M303 increases the target temperature, the
* firmware will wait for the WATCH_TEMP_PERIOD to expire. If the temperature
* hasn't increased by WATCH_TEMP_INCREASE degrees, the machine is halted and
* requires a hard reset. This test restarts with any M104/M109/M303, but only
* if the current temperature is far enough below the target for a reliable
* test.
* If you get false positives for "Heating failed", increase WATCH_TEMP_PERIOD
* and/or decrease WATCH_TEMP_INCREASE. WATCH_TEMP_INCREASE should not be set
* below 2.
#define WATCH_TEMP_PERIOD 20 // Seconds
#define WATCH_TEMP_INCREASE 2 // Degrees Celsius

#define LPQ_MAX_LEN 50
* Automatic Temperature:
* The hotend target temperature is calculated by all the buffered lines of gcode.
* The maximum buffered steps/sec of the extruder motor is called "se".
* Start autotemp mode with M109 S<mintemp> B<maxtemp> F<factor>
* 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.
* On an Ultimaker, some initial testing worked with M109 S215 B260 F1 in the start.gcode
//#define AUTOTEMP
// Show extra position information in M114
//#define M114_DETAIL
// Show Temperature ADC value
// Enable for M105 to include ADC values read from temperature sensors.
* 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
// hot end to reach the target temperature, but the time it takes to reach

* Dual Steppers / Dual Endstops
* This section will allow you to use extra E drivers to drive a second motor for X, Y, or Z axes.
* For example, set X_DUAL_STEPPER_DRIVERS setting to use a second motor. If the motors need to
* spin in opposite directions set INVERT_X2_VS_X_DIR. If the second motor needs its own endstop
* set X_DUAL_ENDSTOPS. This can adjust for "racking." Use X2_USE_ENDSTOP to set the endstop plug
* 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
* this offset is applied to the X2 motor. To find the offset home the X axis, and measure the error
* in X2. Dual endstop offsets can be set at runtime with 'M666 X<offset> Y<offset> Z<offset>'.
#define INVERT_X2_VS_X_DIR true // Set 'true' if X motors should rotate in opposite directions
#define INVERT_Y2_VS_Y_DIR true // Set 'true' if Y motors should rotate in opposite directions
// Enable this for dual x-carriage printers.
// A dual x-carriage design has the advantage that the inactive extruder can be parked which
// prevents hot-end ooze contaminating the print. It also reduces the weight of each x-carriage
// allowing faster printing speeds. Connect your X2 stepper to the first unused E plug.

// However: In this mode the HOTEND_OFFSET_X value for the second extruder provides a software
// override for X2_HOME_POS. This also allow recalibration of the distance between the two endstops
// without modifying the firmware (through the "M218 T1 X???" command).
// Remember: you should set the second extruder x-offset to 0 in your slicer.
// There are a few selectable movement modes for dual x-carriages using M605 S<mode>
