A Switching Extruder is a dual extruder that uses a single stepper motor to drive two filaments, but only one at a time. FAST_PWM_FAN increases the FAN PWM frequency. #endif, #if HAS_BED_PROBE && TEMP_SENSOR_PROBE && TEMP_SENSOR_BED, //#define SAVED_POSITIONS 1 // Each saved position slot costs 12 bytes, #define ARC_SUPPORT // Disable this feature to save ~3226 bytes Use M871 to set values manually. Multiply by 1.414 for peak current. 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). #define Z_MIN_PROBE_ENDSTOP_INVERTING false // set to true to invert the logic of the endstop. Whenever an SD print completes the LCD Menu will open with the same file selected. Since the release of Marlin 2 there is no need to alter the pins_BTT_SKR_V1_3.h as standard. However, control resolution will be halved for each increment; at zero value, there are 128 effective control positions. You can use this option to configure a machine with no Z endstops. #endif, //#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_2 "Preheat for " PREHEAT_1_LABEL, #define USER_GCODE_2 "M140 S" STRINGIFY(PREHEAT_1_TEMP_BED) "\nM104 S" STRINGIFY(PREHEAT_1_TEMP_HOTEND), #define USER_DESC_3 "Preheat for " PREHEAT_2_LABEL, #define USER_GCODE_3 "M140 S" STRINGIFY(PREHEAT_2_TEMP_BED) "\nM104 S" STRINGIFY(PREHEAT_2_TEMP_HOTEND), #define USER_DESC_4 "Heat Bed/Home/Level", #define USER_GCODE_4 "M140 S" STRINGIFY(PREHEAT_2_TEMP_BED) "\nG28\nG29", #define I2CPE_ENC_1_ADDR I2CPE_PRESET_ADDR_X, #define I2CPE_ENC_1_TYPE I2CPE_ENC_TYPE_LINEAR, //#define I2CPE_ENC_1_TICKS_REV (16 * 200), #define I2CPE_ENC_1_EC_METHOD I2CPE_ECM_MICROSTEP, #define I2CPE_ENC_2_ADDR I2CPE_PRESET_ADDR_Y, #define I2CPE_ENC_2_TYPE I2CPE_ENC_TYPE_LINEAR, //#define I2CPE_ENC_2_TICKS_REV (16 * 200), #define I2CPE_ENC_2_EC_METHOD I2CPE_ECM_MICROSTEP, #define I2CPE_ENC_3_ADDR I2CPE_PRESET_ADDR_Z, #define I2CPE_ENC_4_ADDR I2CPE_PRESET_ADDR_E, #define I2CPE_DEF_TYPE I2CPE_ENC_TYPE_LINEAR, #define I2CPE_DEF_TICKS_REV (16 * 200), #define I2CPE_DEF_EC_METHOD I2CPE_ECM_NONE, #define I2CPE_ERR_ROLLING_AVERAGE 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. A “Level Bed” menu item can be added to the LCD with the, Click the controller to view the LCD menu, The LCD will display Japanese, Western, or Cyrillic text. We’ve tried to keep descriptions brief and to the point. SENSORLESS_HOMING: Set SENSORLESS_HOMING sensitivity. Configuring Marlin for your printer. With this option enabled, by default Marlin will use the Z_MIN_PROBE_PIN specified in your board’s pins file (usually the X or Z MAX endstop pin since these are the most likely to be unused). To use TMC2130 stepper drivers in SPI mode connect your SPI2130 pins to the hardware SPI interface on your board and define the required CS pins in your pins_MYBOARD.h file. See the Configuration_adv.h file for the full set of sub-options. Sample PID values are included for reference, but they won’t apply to most setups. The E motor also reverses direction for the second filament. For 1.75mm you’ll use a range more like 1.60 to 1.90. See the Configuration.h file for sub-options and the G29 G-code documentation that applies to your selected leveling system. Use M119 to test if these are set correctly. Some hosts will have this feature soon. M106. Correct for misalignment in the XYZ axes. Scales heater power proportional to the part/layer fan speed which inturn reduces hotend temperature drop range. If CLOCKWISE normally moves DOWN this makes it go UP. This also works fine on a Fotek SSR-10DA Solid State Relay into a 250 W heater. Increase the slowdown divisor for larger buffer sizes. You’ll need to put some of these back later. To unload filament using the LCD menu a generic ramming sequence will be exectued before the MMU2 will retract the filament. If you have SRAM to spare, this option will multiply the resolution of the bilinear grid using the Catmull-Rom subdivision method. To activate hardware reset you define the pin (, If your MMU2 is powered from 12V you can activate a special mode on the MMU2 (. These settings are used to override the home position. Enable this option for a firmware-controlled digital or PWM case light. Extrusion scaling keeps a circular buffer of forward E movements done at each temperature measurement which acts to delay the applied factor and allow for heat dissipation. #if ENABLED(MAX_SOFTWARE_ENDSTOPS), #if EITHER(MIN_SOFTWARE_ENDSTOPS, MAX_SOFTWARE_ENDSTOPS). #define HEATER_4_MAXTEMP 275 You can either double click to open the file or you can open the Arduino IDE software and open it from there. If the second motor has its own endstop set X_DUAL_ENDSTOPS. G28 X Z ; Home the X and Z axes. Marlin supports any kind of probe that can be made to work like a switch. The number of linear motions that can be in the plan at any give time. //#define FIL_RUNOUT_PULLDOWN // Use internal pulldown for filament runout pins. Specify a large enough delay so the servo has enough time to complete a full motion before deactivation. Only AUTO_BED_LEVELING_BILINEAR currently supports SCARA. //#define NANODLP_ALL_AXIS // Enables "Z_move_comp" output on any axis move. During PID calibration, use the highest target temperature you intend to use (where overshoots are more critical). #if ENABLED(G26_MESH_VALIDATION). #if ENABLED(MIN_SOFTWARE_ENDSTOPS), #define MAX_SOFTWARE_ENDSTOPS The most common setting is 0 (LOW) for Active Low. Use DEFAULT_KEEPALIVE_INTERVAL for the default number of seconds between “busy” messages. Reducing acceleration may help to achieve higher top speeds. It also seems like the threshold becomes impossible to get right. By now, the home offset should be ready for the first 3d print test, all we need to do now is test the offset setting… From there you can click to start a new print, or you can navigate elsewhere. This feature exists to prevent irregularities in the bed from propagating through the model’s entire height. Help needed : Marlin z axis homing speed settings. These sub-options can be used when the bed isn’t using PID heating. Validate that endstops are triggered on homing moves. The Sanguino board requires adding “Sanguino” support to Arduino IDE. #define X_CHAIN_POS -1 // <=0 : Not chained. The values are relative E distances and feed rates in mm/m. If your configuration is significantly different than this and you don’t understand the issues involved, you probably shouldn’t use bed PID until it’s verified that your hardware works. This option adds G10/G11 commands for automatic firmware-based retract/recover. Z_AFTER_PROBING will probe then go to 5. Make sure you have enough clearance for the probe to move between points! Two separate X-carriages with extruders that connect to a moving part via a magnetic docking mechanism using movements and no solenoid. Disable to change all LEDs at once. This option reverses the encoder direction everywhere. #define X_MIN_ENDSTOP_INVERTING false // set to true to invert the logic of the endstop. The second set of options applies to changes in target temperature. Ender 5 Pro With BLTouch Marlin bugfix-2.0.x config - ender-5-pro.patch So, outside the bounds of the probed grid, Z adjustment can take one of two approaches. //#define PARK_HEAD_ON_PAUSE // Park the nozzle during pause and filament change.

M915: TMC_Z_CALIBRATION (Deprecated in Marlin 2.0.) To use the MMU2 you also have to, All details are configured in [Configuration_adv.h]. 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. Should be increased for high-resolution encoders. The first serial port (-1 or 0) will always be used by the Arduino bootloader regardless of this setting. For debug-echo: 128 bytes for the optimal speed. Requires 4 bytes SRAM per sensor, plus 4 bytes overhead. This option adds a scaling factor that must be tuned for your setup and material. #define X_MAX_POS X_BED_SIZE Enable these options to constrain movement to the physical boundaries of the machine (as set by [XYZ]_(MIN|MAX)_POS). Here we’re telling the firmware how many individual steps produce a single millimeter (or degree on SCARA) of movement. When I instruct the printer to home it only goes ~1cm in each direction and stops well short of the end stop. These options specify the number of points that will always be probed in each dimension during G29. This allows Marlin to do extra logic related to the bed size when it differs from the movement limits below. #define USE_YMIN_PLUG Marlin-Configurator by @akaJes does it nearly auto-magically with a simple drag/drop operation. Run M502 to set all settings to those specified in your firmware files, then M500 to store these settings in the EEPROM. Homing and probing speeds are constrained by the current max feedrate and max acceleration settings. Enable PID_AUTOTUNE_MENU to add an option on the LCD to run an Autotune cycle and automatically apply the result. Mugga. Leave them undefined for automatic settings. //#define CASE_LIGHT_NO_BRIGHTNESS // Disable brightness control. See the Configuration_adv.h file for the full set of sub-options. When the velocity of any axis changes, its acceleration (or deceleration) in mm/s/s is limited by the current max acceleration setting. #define PARKING_EXTRUDER_SOLENOIDS_DELAY 250 // (ms) Delay for magnetic field. Note that M600 is required for the default FILAMENT_RUNOUT_SCRIPT. This option adds the ability to set a mixture, to save mixtures, and to recall mixtures using the T command. The movement is done at a reduced motor current to prevent breaking parts and promote skipped steps. For all the in-depth details please read the Auto Bed Leveling documentation and the G29 G-codes documentation. #define DEFAULT_KEEPALIVE_INTERVAL 2 // Number of seconds between "busy" messages. #define ADVANCED_PAUSE_RESUME_PRIME 0 // (mm) Extra distance to prime nozzle after returning from park. Maximum temperature for each temperature sensor. Set the default stall thresholds with *_STALL_SENSITIVITY. MIXING_EXTRUDER enables M163 - set mix factor, M164 - save mix, and M165 - set mix. Sub-options determine how long to show the progress bar and status message, how long to retain the status message, and whether to include a progress bar test in the Debug menu. In a single-nozzle setup, only one filament drive is engaged at a time, and each needs to retract before the next filament can be loaded and begin purging and extruding. By default all endstops have pulldown resistors disabled. Character-based displays (based on the Hitachi HD44780) provide an ASCII character set plus one of the following language extensions: To determine the language extension installed on your controller: See LCD Language System for in-depth info on how the Marlin display system currently works. The serial communication speed of the printer should be as fast as it can manage without generating errors. #define PREHEAT_1_TEMP_BED 70 Test each axis for proper movemnt using the host or LCD “Move Axis” menu. Available with MESH_BED_LEVELING, AUTO_BED_LEVELING_BILINEAR, and AUTO_BED_LEVELING_UBL. Also option requires: BABYSTEPPING, BABYSTEP_ZPROBE_OFFSET, Z_SAFE_HOMING, and a minimum Z_HOMING_HEIGHT of 10. These options specify the default number of points to probe in each dimension during G29. These options allow you to use extra E drivers to drive a second motor for X, Y, and/or Z axes. Nonetheless the next step of configuring the SKR V1.4 is a few lines in the pins_BTT_SKR_V1_4.h file, for those wishing to use the SD Card EEPROM emulation, or are using Marlin firmware version under A controller fan is useful to cool down the stepper drivers and MOSFETs. This feature is so sensitive that it can actually take the place of traditional endstops. Enable to use SD printing, whether as part of an LCD controller or as a standalone SDCard slot. This simplifies all coordinate transformations, leveling, etc., and may allow for slightly faster printing. So-called “cold extrusion” can damage a machine in several ways, but it usually just results in gouged filament and a jammed extruder. Should be slower than load feedrate. Heating may be slowed in a cold environment, if a fan is blowing on the heat block, or if the heater has high resistance. #define DISABLE_INACTIVE_E true, #define DEFAULT_MINIMUMFEEDRATE 0.0 Requires an LCD display. We’ll customise our configuration now: Setting this incorrectly will lead to unpredictable results. The G26 command accepts parameters for nozzle size, layer height, etc. If an endstop shows up as “TRIGGERED” when not pressed, and “open” when pressed, then it should be inverted here. Open Preferences and locate the Additional Boards Manager URLs field. The value must be greater than or equal to MEASUREMENT_DELAY_CM. 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. Deltas have three max endstops. //#define BABYSTEP_XY // Also enable X/Y Babystepping. // For direct drive, the full length of the nozzle. Start by downloading the latest stable release of Marlin from here. { 1.0, 1500 }, \ #endif. The E disable option works like DISABLE_[XYZ] but pertains to one or more extruders. This option works around that bug, but otherwise should be left off. Junction Deviation determins the cornering speed. Serial port -1 is the USB emulated serial port, if available. Probes can share the Z min plug, or can use one or more of the extra connectors. #define HOMING_BUMP_DIVISOR { 2, 2, 4 }, #define Z_STEPPER_ALIGN_XY { { 10, 190 }, { 100, 10 }, { 190, 190 } }, //#define Z_STEPPER_ALIGN_KNOWN_STEPPER_POSITIONS, #if ENABLED(Z_STEPPER_ALIGN_KNOWN_STEPPER_POSITIONS), #define Z_STEPPER_ALIGN_STEPPER_XY { { 210.7, 102.5 }, { 152.6, 220.0 }, { 94.5, 102.5 } }, #define G34_MAX_GRADE 5 // (%) Maximum incline that G34 will handle, #define Z_STEPPER_ALIGN_ITERATIONS 5 // Number of iterations to apply during alignment, #define Z_STEPPER_ALIGN_ACC 0.02 // Stop iterating early if the accuracy is better than this, #define AXIS_RELATIVE_MODES { false, false, false, false }, #define INVERT_X_STEP_PIN false Here is the situation: I am currently using a Gen 6 Sanguino ATmega644P board, Arduino 0022, Marlin version "1.0.0 Beta 1". #define Z_MAX_ENDSTOP_INVERTING false // set to true to invert the logic of the endstop. M304 can be used to set bed PID. Run M502 to set all settings to those specified in your firmware files, then M500 to store these settings in the EEPROM. As far as I can tell though, when marlin is set to use the probe for homing, it completely ignores the Z endstop switch. #define E1_AUTO_FAN_PIN -1 { 10.0, 700 }, \ #define FIL_RUNOUT_PULLUP // Use internal pullup for filament runout pins. #endif, #define MAX_CMD_SIZE 96 #define THIS_IS_ENABLED // this switch is enabled, //#define THIS_IS_DISABLED // this switch is disabled, #define OPTION_VALUE 22 // this setting is "22", #define STRING_CONFIG_H_AUTHOR "(none, default config)", #define SHOW_BOOTSCREEN Removes the PWM noise but increases heating in the FET/Arduino. The Z offset can be overridden with M851 Z or the LCD controller. #define INVERT_Z_STEP_PIN false By now, the home offset should be ready for the first 3d print test, all we need to do now is test the offset setting, like in step 5, just to confirm we are ready to go. Touch-MI Probe by hotends.fr is deployed and activated by moving the X-axis to a magnet at the edge of the bed. Not having Delta, or CoreXY printers included. To use one of the servo connectors for this type of probe, set Z_ENDSTOP_SERVO_NR in the probe options above. #endif // I2C_POSITION_ENCODERS, #define JOY_X_PIN 5 // RAMPS: Suggested pin A5 on AUX2, #define JOY_Y_PIN 10 // RAMPS: Suggested pin A10 on AUX2, #define JOY_Z_PIN 12 // RAMPS: Suggested pin A12 on AUX2, #define JOY_EN_PIN 44 // RAMPS: Suggested pin D44 on AUX2, //#define INVERT_JOY_X // Enable if X direction is reversed, //#define INVERT_JOY_Y // Enable if Y direction is reversed, //#define INVERT_JOY_Z // Enable if Z direction is reversed. Discussion. The photo can be triggered by a digital pin or a physical movement. SENSORLESS_HOMING: Set SENSORLESS_HOMING sensitivity. Your board’s pins file already specifies the recommended pins. Setting this to anything other than 255 enables a form of PWM. EDIT - don't forget to save and upload Marlin to your board when finished. I'm using the Marlin firmware (1.1.0-RC7 - 31 July 2016) for a 3d printer. While there are other settings that may need changing within Configuration_adv, these are non-specific to the SKR V1.4 and tend to be machine specific. Using a single wire for the control signal and another for the return “move complete” signal to signify whether or not the move was able to be made successfully. These settings allow Marlin to tune stepper driver timing and enable advanced options for stepper drivers that support them. Start G32 at X100 Y100 and it should also succeed.
