#define MESH_TEST_NOZZLE_SIZE 0.4 // (mm) Diameter of primary nozzle. The BLOCK_BUFFER_SIZE must be a power of 2, (8, 16, 32, etc.) The BLTouch uses the servo connector and is controlled using specific servo angles. When the machine is idle and the temperature over a given value, Marlin can extrude a short length of filament every couple of seconds. Employ an external closed loop controller that can be activated or deactivated by the main controller. Certain types of probe need to stay away from the edge. Settings saved to EEPROM (with M500) are loaded automatically whenever the machine restarts (and in most setups, when connecting to a host), overriding the defaults set in the configuration files. Take rough measurements from the probe to the nozzle in X and Y directions and for the z: BLTouch. Enable the Bluetooth serial interface.

Use these options to set to the state (HIGH or LOW) that applies to each endstop and the Z probe, if enabled. In retraction moves, DEFAULT_RETRACT_ACCELERATION applies only to the E-axis. Probes can share the Z min plug, or can use one or more of the extra connectors. // Filament can be extruded repeatedly from the Filament Change menu. With Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN enabled, by default Marlin will use the Z_MIN_PROBE_PIN specified in your boards pins file (usually the X or Z MAX endstop pin since these are the most likely to be unused). If the magnet is on the right, enable and set TOUCH_MI_DEPLOY_XPOS to the deploy position. If CLOCKWISE normally moves UP this makes it go DOWN. { 1.0, 1000 }, \ In a Dual X-Carriage setup the first X-carriage (T0) homes to the minimum endstop, while the second X-carriage (T1) homes to the maximum endstop. This value raises Z to the specified height above the bed before homing X or Y. If stepper drivers time out, X and Y homing will be required again.

MESH_G28_REST_ORIGIN moves the nozzle to rest at Z_MIN_POS when mesh probing is done. Only one extruder can have a filament sensor. Try to match your brand and model with one of the sensors in the list. These depend on various factors, including belt pitch, number of teeth on the pulley, thread pitch on leadscrews, micro-stepping settings, and extruder style. // For direct drive, the full length of the nozzle.

I did a similar print off of something that does the same .. The target temperature is set to mintemp + factor * se[steps/sec] and is limited by mintemp and maxtemp. To activate hardware reset you define the pin (, If your MMU2 is powered from 12V you can activate a special mode on the MMU2 (. NO=HIGH. If you have a board with pins named X_MS1, X_MS2, etc., then you can change the micro-stepping using G-code or the LCD menu. This option may be needed if your Z driver tends to overheat. Marlin supports four kinematic motion systems: Cartesian, Core (H-Bot), Delta, and SCARA.

For configuration options see G-code M593. RIGIDBOT_PANEL|RigidBot Panel V1.0. The Pra Calculator is a great tool to help find the right values for your specific printer configuration. The extruder still uses a single E axis, while the current mixture is used to determine the proportion of each filament to use. By default all endstops have pulldown resistors disabled. With this feature, a mechanical or opto endstop switch is used to check for the presence of filament in the feeder (usually the switch is closed when filament is present). In that case the probe will be used to home Z and you will need to enable Z_SAFE_HOMING to ensure that the probe is positioned over the bed when homing the Z axis - done after X and Y. This enables you to test the reliability of your probe. These values specify the offset from the first nozzle to each nozzle. All forms of bed control obey this (PID, bang-bang, bang-bang with hysteresis). 300ms is a good value but you can try less delay. Test audio output with the G-code M300 S P. In Marlin, you set the maximum feed rates ( speeds ) by changing : /** * Default Max Feed Rate (mm/s) * Override with M203 * X, Y, Z, E0 [ [,|E1 [ [,|E2 [, E3]]]]] */ #define DEFAULT_MAX_FEEDRATE { 500, 500, 2.25, 45 } Note the unit is millimeters per seconds.

If each layer is 0.2 mm high, leveling compensation will be reduced by 1/50th (2 %) after each layer. Marlin includes support for several controllers. You can then use M111 S32 before issuing G28 and G29 V4 to get a detailed log of the process for diagnosis. This feature allows Marlin to use linear pressure control for print extrusion, to eliminate ooze, improve corners, etc. They provide pretty complete descriptions of each option, and are themselves the source for most of the information presented here. If you have a watchdog reboot in an ATmega2560 the device can hang forever, as a watchdog reset will leave the watchdog on. // Calculate as (FTM_STEPPER_FS / FTM_FS). When using any of the mesh-based leveling systems (1.1.7) you can activate G26_MESH_VALIDATION to print test patterns and fine-tune the mesh. I use the ABL baseline even though I don't have ABL. This offset can be saved to EEPROM with M500. However, control resolution will be halved for each increment; at zero value, there are 128 effective control positions. Override with M113. This uses a very low frequency which is not as annoying as with the hardware PWM. #endif, #define SD_FIRMWARE_UPDATE_EEPROM_ADDR 0x1FF, #define SD_FIRMWARE_UPDATE_ACTIVE_VALUE 0xF0, #define SD_FIRMWARE_UPDATE_INACTIVE_VALUE 0xFF GitHub. Incrementing this by 1 will double the software PWM frequency, affecting heaters (and the fan if FAN_SOFT_PWM is enabled). Use to override if the automatically selected points are inadequate. Although home positions are fixed, M206 can be used to apply offsets to the home position if needed. Most people might think of printers as having four motors - one for each direction and one for the extruder. The values set here apply over and above any (negative) probe Z Offset set with Z_PROBE_OFFSET_FROM_EXTRUDER, M851, or the LCD. This also works with auto bed leveling enabled and will be triggered only when the Z axis height is less than the defined value, otherwise the Z axis will not move. Start with 250000 and only go lower if line number and checksum errors start to appear. Enabling MK2_MULTIPLEXER allows one stepper driver on a control board to drive two to eight stepper motors, one at a time. Workspaces set with this feature are also saved to EEPROM. //#define CASE_LIGHT_USE_NEOPIXEL // Use NeoPixel LED as case light, requires NEOPIXEL_LED. Disabling the steppers between moves gives the motors and drivers a chance to cool off. Having to revise your configurations every update certainly doesn't help. For a more detailed explanation of the process see G76_M871.cpp and Configuration_adv.h. This is the nominal filament diameter as written on the filament spool (1.75, 2.85, 3.0). So, outside the bounds of the probed grid, Z adjustment can take one of two approaches. This option is useful to figure out the cause of unexpected behaviors, or when reporting issues to the project.

When stepper drivers reach a certain temperature theyll turn off, either stuttering or stopping. Setting these too high will cause the corresponding stepper motor to lose steps, especially on high speed movements. Probing should be done quickly, but the Z speed should be tuned for best repeatability. Setting this incorrectly will lead to unpredictable results. The photo can be triggered by a digital pin or a physical movement. Uncomment ONE of these options to use a slower SPI transfer speed. Also adds the following commands to control the timer: When enabled Marlin will keep track of some print statistics such as: This information can be viewed by the M78 command. This option causes the printer to give status feedback on the installed color LED, BLINKM, or PCA9632: The total number of servos to enable for use. Enable if your probe or endstops falsely trigger due to noise. * NOTE: This option sacrifices some cooling fan speed options. These values can be overridden using the M145 command or the Control > Temperature > Preheat Material X conf submenus. #define DEFAULT_KEEPALIVE_INTERVAL 2 // Number of seconds between "busy" messages. #define Z_CLEARANCE_BETWEEN_PROBES 5 // Z Clearance between probe points MIXING_EXTRUDER enables M163 - set mix factor, M164 - save mix, and M165 - set mix. This results in poor accuracy and carries a strong probability of axial drift (i.e., lost steps). As long as the temperature reading is low, the hotend will continue to heat up indefinitely, leading to smoke, oozing, a ruined print, and possibly even fire. If the temperature difference between sensors exceeds MAX_REDUNDANT_TEMP_SENSOR_DIFF Marlin will abort the print and disable the heater. Increase SOFT_PWM_SCALE if the frequency is too low. The sub-options above specify the default values that will be applied for omitted parameters. If the temperature fails to rise enough within a certain time period (by default, 2 degrees in 20 seconds), the machine will shut down with a , Monitor thermal stability. If CLOCKWISE normally moves DOWN this makes it go UP. Usually the [XYZ]_MIN_POS values are set to 0, because endstops are positioned at the bed limits. BQ_LCD_SMART_CONTROLLER|BQ LCD Smart Controller shipped with the BQ Hephestos 2 and Witbox 2. Thermal protection is one of the most vital safety features in Marlin, allowing the firmware to catch a bad situation and shut down heaters before it goes too far. For example, G1 Z-100 can be min constrained to G1 Z0. Activate this option to make volumetric extrusion the default method The last values loaded or set by M404 W and M200 D will be used as the Nominal and Actual filament diameters. For false thermal runaways not caused by a loose temperature sensor, try increasing WATCH_TEMP_PERIOD or decreasing WATCH_TEMP_INCREASE. 0 for classic; 1 for Pra info screen style. This uses a very low frequency which is not as annoying as with the hardware PWM. Sample Bed PID values are included for reference, but use the result from M303 E-1 for your specific machine. If the second motor has its own endstop set X_DUAL_ENDSTOPS. #define FILAMENT_UNLOAD_PURGE_DELAY 5000 // (ms) Delay for the filament to cool after retract. However, this feature is unsafe because it only works if interrupts are disabled, and the code could hang in an interrupt routine with interrupts disabled. An inexpensive RGB LED can be used simply by assigning digital pins for each component. See Configuration_adv.h for more information. #define PREHEAT_2_TEMP_BED 110 If the filament runs out, Marlin will run the specified G-code script (by default M600). DO NOT enable E2_DRIVER_TYPE - this may produce undesirable results that can harm your machine. These offsets specify the distance from the tip of the nozzle to the probe or more precisely, to the point at which the probe triggers. See Configuration_adv.h for more details.

See the Configuration.h file for sub-options and the G29 G-code documentation that applies to your selected leveling system. The Philips PCA9632 is a common PWM LED driver, controlled (like BlinkM) using I2C. Most settings will come over without changes, then you can review any tricky changes that remain. These can be set explicitly in Configuration_adv.h. The PID settings should be tuned whenever changing a hotend, temperature sensor, heating element, board, power supply voltage (12/24V), or anything else related to the high-voltage circuitry. See Laser and Spindle (1.1.x) or Laser and Spindle (2.0.9.x) and Configuration_adv.h for more details. Agree entirely! #define EEPROM_CHITCHAT // Give feedback on EEPROM commands.
