If you get too many Heating failed errors, increase WATCH_BED_TEMP_PERIOD and/or decrease WATCH_BED_TEMP_INCREASE. The firmware needs to know what board it will be running on so it can assign the right functions to all pins and take advantage of the full capabilities of the board. The steps to do so are defined using. Marlin now checks for a configuration version and wont compile without this setting. These options specify the inset, grid, and 3-point triangle to use for UBL. 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 the second motor has its own endstop set X_DUAL_ENDSTOPS. Tune what stable means using TEMP_HYSTERESIS and TEMP_WINDOW. To indicate a Servo Z Probe (e.g., an endstop switch mounted on a rotating arm) just specify the servo index. There is a way to increase the probing accuracy by using double probing where the second probe is advancing slower to the build platform as can be seen in the Marlin Configuration.h file: // Feedrate (mm/m) for the first approach when double-probing (MULTIPLE_PROBING == 2) #define Z_PROBE_SPEED_FAST HOMING_FEEDRATE_Z // Feedrate (mm/m) for the . #endif. { 14.4, 871 }, \ If your configuration is significantly different than this and you dont understand the issues involved, you probably shouldnt use bed PID until its verified that your hardware works. To increase the homing speed, increase HOMING_FEEDRATE_XY from (20*60) to (40*60) and HOMING_FEEDRATE_Z from (4*60) to (8*60). #define HOMING_FEEDRATE {50*60, 50*60, 4*60, 0} // set the homing speeds (mm/min) // default settings: RAMPS-based boards use SERVO3_PIN. #define TEMP_SENSOR_BED 0 The one you are asking about is#define DEFAULT_MAX_FEEDRATE. I notice this at x and y axis but they definitely are not as slow as the z axis. The planner uses the default accelerations set here (or by M204) as the starting values for movement acceleration, and then constrains them further, if needed. Why do they do it that way? If you have a single nozzle, a switching extruder, a mixing extruder, or dual X carriages, specify that below. #endif, #define CHAMBER_PULLUP_RESISTOR_OHMS 4700 // Pullup resistor, #define CHAMBER_RESISTANCE_25C_OHMS 100000 // Resistance at 25C, #define CHAMBER_BETA 3950 // Beta value #define Y_MIN_ENDSTOP_HIT_STATE HIGH (Enums in ft_types.h). To unload filament using the LCD menu a generic ramming sequence will be executed before the MMU2 will retract the filament. Link. Jerk is the maximum change in velocity (in mm/sec) that can occur instantaneously. Without this option all temperatures must be specified in Celsius units. There is conditional code for Deltas there, since it needs to home up all three axes at once. Available with MESH_BED_LEVELING, AUTO_BED_LEVELING_BILINEAR, and AUTO_BED_LEVELING_UBL. The buffer size is calculated automatically from SHAPING_FREQ_[XY], DEFAULT_AXIS_STEPS_PER_UNIT, DEFAULT_MAX_FEEDRATE and ADAPTIVE_STEP_SMOOTHING. * M3: 30 = Clockwise, 31 = Counter-Clockwise Most 3D printers use an open loop control system, meaning the software cant ascertain the actual carriage position at a given time. * Speed / Power can be set ('M3 S') and displayed in terms of: If CLOCKWISE normally moves UP this makes it go DOWN. The high amperage generated by extruder motor wiring during movement can also induce movement in active servos. See Laser and Spindle (1.1.x) or Laser and Spindle (2.0.9.x) and Configuration_adv.h for more details. Heatinging the bed and extruder for probing will produce results that more accurately correspond with your bed if you typically print with the bed heated. Friday Facts 4: How to Marlin Polargraph. #define AXIS_RELATIVE_MODES { false, false, false, false }, #define INVERT_X_STEP_PIN false During PID calibration, use the highest target temperature you intend to use (where overshoots are more critical). Set these to the lowest value (in degrees C) that the machine is likely to experience. Here you define the G-code script which will be executed when the so-called FINDA sensor on the MMU2 detects a filament runout. Youll 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. #endif, #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 #define HEATER_1_MAXTEMP 275 The BLINKM board supplies the backlighting for some LCD controllers. Up to 25 may be defined, but the actual number is LCD-dependent. Axes moving the wrong direction can cause damage.

For example, if you set this to My Delta the LCD will display My Delta ready when the printer starts up.

You may also override timing options in Configuration_adv.h. Before deploy/stow pause for user confirmation.
