| #define SHOW_BOOTSCREEN |
*** VENDORS PLEASE READ ***
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.
| #define SERIAL_PORT 0 |
Select the serial port on the board to use for communication with the host. This allows the connection of wireless adapters (for instance) to non-default port pins. Note: The first serial port (-1 or 0) will always be used by the Arduino bootloader.
:[-1, 0, 1, 2, 3, 4, 5, 6, 7]
| #define BAUDRATE 250000 |
Select a secondary serial port on the board to use for communication with the host. This allows the connection of wireless adapters (for instance) to non-default port pins. Serial port -1 is the USB emulated serial port, if available.
:[-1, 0, 1, 2, 3, 4, 5, 6, 7] This setting determines the communication speed of the printer.
250000 works in most cases, but you might try a lower speed if you commonly experience drop-outs during host printing. You may try up to 1000000 to speed up SD file transfer.

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)
| #define PREVENT_COLD_EXTRUSION |
Prevent extrusion if the temperature is below EXTRUDE_MINTEMP. Add M302 to set the minimum extrusion temperature and/or turn cold extrusion prevention on and off.
*** IT IS HIGHLY RECOMMENDED TO LEAVE THIS OPTION ENABLED! ***
| #define EXTRUDE_MINTEMP 170 |
| #define PREVENT_LENGTHY_EXTRUDE |
Prevent a single extrusion longer than EXTRUDE_MAXLENGTH. Note: For Bowden Extruders make this large enough to allow load/unload.
| #define EXTRUDE_MAXLENGTH 200 |
| #define THERMAL_PROTECTION_HOTENDS |
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

These settings can be reset by M502
Note that if EEPROM is enabled, saved values will override these. With this option each E stepper can have its own factors for the following movement settings.

Junction Deviation Factor
See: https://reprap.org/forum/read.php?1,739819 http://blog.kyneticcnc.com/2018/10/computing-junction-deviation-for-marlin.html S-Curve Acceleration
This option eliminates vibration during printing by fitting a Bézier curve to move acceleration, producing much smoother direction changes.
See https://github.com/synthetos/TinyG/wiki/Jerk-Controlled-Motion-Explained Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN
Enable this option for a probe connected to the Z Min endstop pin.
| #define NOZZLE_TO_PROBE_OFFSET { 10, 10, 0 } |
Z_MIN_PROBE_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.
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. 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. The BLTouch probe uses a Hall effect sensor and emulates a servo. 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.
Also requires: BABYSTEPPING, BABYSTEP_ZPROBE_OFFSET, Z_SAFE_HOMING, and a minimum Z_HOMING_HEIGHT of 10. Z Probe to nozzle (X,Y) offset, relative to (0, 0).
In the following example the X and Y offsets are both positive:
#define NOZZLE_TO_PROBE_OFFSET { 10, 10, 0 }
+– BACK —+ | | L | (+) P | R <– probe (20,20) E | | I F | (-) N (+) | G <– nozzle (10,10) T | | H | (-) | T | | O– FRONT –+ (0,0)
Specify a Probe position as { X, Y, Z }

| #define XY_PROBE_SPEED 8000 |
| #define Z_PROBE_SPEED_FAST HOMING_FEEDRATE_Z |
| #define Z_PROBE_SPEED_SLOW (Z_PROBE_SPEED_FAST / 2) |
| #define Z_CLEARANCE_DEPLOY_PROBE 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. 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 NOZZLE_TO_PROBE_OFFSET, 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. But: M851 Z+1 with a CLEARANCE of 2 => 2mm from bed to nozzle.

| #define X_ENABLE_ON 0 |
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 readings with inductive probes and piezo sensors.

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:
Marlin automatically computes skew factors from these measurements. Skew factors may also be computed and set manually:
If desired, follow the same procedure for XZ and YZ. Use these diagrams for reference:
Y Z Z ^ B----—C ^ B----—C ^ B----—C | / / | / / | / / | / / | / / | / / | A----—D | A----—D | A----—D +-----------—>X +-----------—>X +-----------—>Y XY_SKEW_FACTOR XZ_SKEW_FACTOR YZ_SKEW_FACTOR EEPROM
Persistent storage to preserve configurable settings across reboots.
M500 - Store settings to EEPROM. M501 - Read settings from EEPROM. (i.e., Throw away unsaved changes) M502 - Revert settings to "factory" defaults. (Follow with M500 to init the EEPROM.)

Nozzle Park
Park the nozzle at the given XYZ position on idle or G27.
The "P" parameter controls the action applied to the Z axis:
P0 (Default) If Z is below park Z raise the nozzle. P1 Raise the nozzle always to Z-park height. P2 Raise the nozzle by Z-park amount, limited to Z_MAX_POS. Clean Nozzle Feature – EXPERIMENTAL
Adds the G12 command to perform a nozzle cleaning process.
Parameters: P Pattern S Strokes / Repetitions T Triangles (P1 only)
Patterns: P0 Straight line (default). This process requires a sponge type material at a fixed bed location. "S" specifies strokes (i.e. back-forth motions) between the start / end points.
P1 Zig-zag pattern between (X0, Y0) and (X1, Y1), "T" specifies the number of zig-zag triangles to do. "S" defines the number of strokes. Zig-zags are done in whichever is the narrower dimension. For example, "G12 P1 S1 T3" will execute:
| (X0, Y1) | /\ /\ /\ | (X1, Y1) | | / \ / \ / \ | A | | / \ / \ / \ | | | / \ / \ / \ | | (X0, Y0) | / \/ \/ \ | (X1, Y0) – +-----------------------------—+ |________|_________|_________| T1 T2 T3
P2 Circular pattern with middle at NOZZLE_CLEAN_CIRCLE_MIDDLE. "R" specifies the radius. "S" specifies the stroke count. Before starting, the nozzle moves to NOZZLE_CLEAN_START_POINT.
Caveats: The ending Z should be the same as starting Z. Attention: EXPERIMENTAL. G-code arguments may change. Print Job Timer
Automatically start and stop the print job timer on M104/M109/M190.
M104 (hotend, no wait) - high temp = none, low temp = stop timer M109 (hotend, wait) - high temp = start timer, low temp = stop timer M190 (bed, wait) - high temp = start timer, low temp = none
The timer can also be controlled with the following commands:
M75 - Start the print job timer M76 - Pause the print job timer M77 - Stop the print job timer

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. *** CAUTION ***
LED Type. Enable only one of the following two options. Printer Event LEDs
During printing, the LEDs will reflect the printer status:
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.
