Be careful when first setting these. Panucatt VIKI LCD with status LEDs, integrated click & L/R/U/D buttons, separate encoder inputs. Changing to HOMING_FEEDRATE_XY (20*60) made homing safe for use. See Configuration_adv.h for further information. #define INVERT_E1_DIR false Otherwise, adjust according to your host. Otherwise the RED led is on. //#define BABYSTEP_XY // Also enable X/Y Babystepping. If you have a watchdog reboot in an ATmega2560 the device can hang forever, as a watchdog reset will leave the watchdog on. These settings allow Marlin to tune stepper driver timing and enable advanced options for stepper drivers that support them. { -50.0, 2000 }, #define MMU2_FILAMENTCHANGE_EJECT_FEED 80.0, #define MMU2_DEBUG // Write debug info to serial output, JD Explained and Visualized, by Paul Wanamaker, RepRapDiscount Full Graphic Smart Controller, Baricuda Extruder for 3D Printing Sugar and Chocolate, Filament Width Sensor Prototype Version 3, PANELOLU2 LCD with status LEDs, separate encoder and click inputs. If each layer is 0.2 mm high, leveling compensation will be reduced by 1/50th (2 %) after each layer. Use software PWM to drive the fan. Enable the Bluetooth serial interface. Use DEFAULT_KEEPALIVE_INTERVAL for the default number of seconds between busy messages. Qantip (Qantip) March 21, 2021, 6:18am #3. For DELTA Z home must be set to the top-most position. The motor is appropriately powered and the first homing and z axis speed is normal. For a more detailed explanation of the process see G76_M871.cpp and Configuration_adv.h. #define SHAPING_ZETA_Y 0.15f // Damping ratio of the Y axis (range: 0.0 = no damping to 1.0 = critical damping). With this disabled, the printer will move to Z0 for the first probe point. #define FTM_ZMAX 100 // Maximum delays for shaping functions (even numbers only!). Set the servo sub-settings above according to your particular extruders setup instructions. SENSORLESS_HOMING will still need endstop connectors declared. Indoor temperatures range from 10C-40C, but a value of 0 might be appropriate for an unheated workshop. Before testing, move the carriage and bed to the middle. Turn on with M540 S1 (or from the LCD menu) and make sure endstops are enabled (M120) during SD printing. If Marlin reads a temperature above these values, it will immediately shut down for safety reasons. Try to match your brand and model with one of the sensors in the list. #define USE_ZMIN_PLUG, // Disable ENDSTOPPULLUPS to set pullups individually, // Disable ENDSTOPPULLDOWNS to set pulldowns individually, #define X_MIN_ENDSTOP_HIT_STATE HIGH Read on for firmware configuration. #define BED_MAXTEMP 130, #define PIDTEMP The ASCII buffer for serial input. Configuration Files/Default E3V2 Config/Con Use the M280 command to find the best Z_SERVO_ANGLES values. Support CNC-style G-code dialects used by laser cutters, drawing machine cams, etc. To do this it moves each axis towards one end of its track until it triggers a switch, commonly called an "endstop." Marlin knows where the endstops are, so once all the endstops have been triggered the position is known. #define AXIS_RELATIVE_MODES { false, false, false, false }, #define INVERT_X_STEP_PIN false The E motor also reverses direction for the second filament. #define PAUSE_PARK_RETRACT_LENGTH 2 // (mm) Initial retract. The servo is used to switch the side of the extruder that will drive the filament. Most 3D printers use an open loop control system, meaning the software cant ascertain the actual carriage position at a given time. There is a bonus setting - I have changed the homing feedrates with HOMING_FEEDRATE_MM_M in Configuration.h to higher values of 150*60 mm per minute for X and Y and 10*60 for Z so Homing is now also much faster. * NOTE: This option sacrifices some cooling fan speed options. Set to 3 or more for slow probes - the average result will be used. I did a similar print off of something that does the same .. #define FTM_SHAPING_DEFAULT_Y_FREQ 37.0f // (Hz) Default peak frequency used by input shapers. This test restarts with any M104/M109, but only if the current temperature is far enough below the target for a reliable test. Bang-bang is a pure binary mode - the heater is either fully-on or fully-off for a long period. By default, the magnet is assumed to be on the left and activated by a home. To solve this issue, this option sets the number of milliseconds a hotend will preheat before Marlin starts to check the temperature. Set a delay sufficient to reach a temperature your sensor can reliably read. This is the nominal filament diameter as written on the filament spool (1.75, 2.85, 3.0). With simple digital pins only 7 colors are possible. * a planner block. // This is for Pra MK3-style extruders. The default BLTouch settings can be overriden with these options. The bed must maintain a stable temperature for TEMP_BED_RESIDENCY_TIME before M109 will return success and start the print. */, /** #define TEMP_WINDOW 1 // (degC) Window around target to start the residency timer x degC early. //For beds that fall when Z is powered off. I have these features enabled : 250,000 Baud serial rate Enabled- ive also had working up to 1 million baud - but I tuned it down until I know more. On the other hand, if this frequency is too low, you should also increment SOFT_PWM_SCALE. // For Bowden, the full length of the tube and nozzle. // Try increasing this value if stepper motion is not smooth. Take account of the probes XY offsets when setting these boundaries. NC=LOW. SuperPid is a router/spindle speed controller used in the CNC milling community. It takes the guess-work out of getting a good first layer and good bed adhesion. //#define ADVANCED_PAUSE_FANS_PAUSE // Turn off print-cooling fans while the machine is paused. MESH_BED_LEVELING is incompatible with Delta and SCARA. The sub-options above specify the default values that will be applied for omitted parameters.

Setting this incorrectly will lead to unpredictable results. If the jerk is set too high, direction changes will apply too much torque and you may see ringing artifacts or dropped steps. Multiple extruders can be assigned to the same pin in which case the fan will turn on when any selected extruder is above the threshold.

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.

Use to override if the automatically selected points are inadequate. Marlin supports four kinematic motion systems: Cartesian, Core (H-Bot), Delta, and SCARA. This option reverses the encoder direction for Select Screen If CLOCKWISE normally moves LEFT this makes it go RIGHT. Turn off after the print has finished and the user has pushed a button. Auto-report position with M154 S. Friday Facts 4: How to Marlin Polargraph. When PWM fans are set to low speed, they may need a higher-energy kickstart first to get moving. As with PIDTEMPBED, dont enable this unless your bed hardware is ok with PWM. #define SD_MENU_CONFIRM_START, #define EVENT_GCODE_SD_STOP "G28XY" Requires an LCD display. If youve never configured and calibrated a 3D Printer before, here are some good resources: To get your core Configuration.h settings right youll need to know the following things about your printer: The core and default settings of Marlin live in the Configuration.h file. It is no longer enabled automatically for LCD controllers with built-in SDCard slot. No delay if 0 or not defined. SCARA robots move an arm in the XY plane using two angular joints. { 1.5, 3000 }, \ When you first start up your machine it has no idea where the toolhead is positioned, so Marlin needs to use a procedure called "homing" to establish a known position. 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. Some hosts will have this feature soon. Configuration Files/Alex's Config/Configuration_adv.h Configuration_adv.h ; Default E3V2 Config . ELB_FULL_GRAPHIC_CONTROLLER|Adafruit ST7565 Full Graphic Controller. Should be slower than load feedrate. */, #define G26_MESH_VALIDATION // Enable G26 mesh validation In practice with a well-calibrated machine this is not an issue and using open loop is a major cost saving with excellent quality. Enable this option for a firmware-controlled digital or PWM case light. 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. 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. Set to 2 for a fast/slow probe - the second probe result will be used. Test audio output with the G-code M300 S P. Enable this option if a probe (not an endstop) is being used for Z homing.
