Limits placed on other axes also apply. Specify this type for an inductive probe or when using the nozzle itself as the probe. Z Safe Homing isnt needed if a Z endstop is used for homing, but it may also be enabled just to have XY always move to some custom position after homing. Measure NOZZLE_TO_PROBE_OFFSET.

Requires fans with tachometer pins. The Ender-3 will become a very popular printer, if not already, and many users will upgrade the Marlin firmware as I did. With Marlin's homing routines you could locate position, and new options coming in the near future will give real time feed back (more on that later) What needs to be tweaked Pour yourself a drink and settle in. Scales heater power proportional to the part/layer fan speed which in turn reduces hotend temperature drop range. The sample values here apply to 3mm. In most setups these can be left unchanged, but should be tuned as needed to prevent false positives. Until they reach a sufficient temperature, these sensors usually return the lowest raw value, and this will cause a Min Temp Error. Temperature sensors are vital components in a 3D printer. On a board with a ATmega2560/1280 micro-controller you have three potential serial ports to use for the MMU2: serial 1 (pins 18/19), serial 2 (pins 16/17), serial 3 (pins 14/15). I've compiled it, but as I said I can't test it as I don't have Z probing installed. #define FANMUX1_PIN -1 #define FTM_LINEAR_ADV_DEFAULT_ENA false // Default linear advance enable (true) or disable (false). It is very flexible with a few changes. { -14.0, 1200 }, \ Configuration Files/Alex's Config/Configuration_adv.h Configuration_adv.h ; Default E3V2 Config . A custom script to do at the very end of G29. The SLED_DOCKING_OFFSET specifies the extra distance the X axis must travel to pickup the sled. 0 should be fine but it may be pushed further if needed. * Enable the G26 Mesh Validation Pattern tool. // 3/2 * (FTM_FS / FTM_MIN_SHAPE_FREQ) for 2HEI. #define Z_MAX_ENDSTOP_HIT_STATE HIGH ANET_FULL_GRAPHICS_LCD|Anet Full Graphics LCD for the Anet A3.

Start with 250000 and only go lower if line number and checksum errors start to appear. Employ an external closed loop controller that can be activated or deactivated by the main controller. I notice this at x and y axis but they definitely are not as slow as the z axis. The minimum pulse width (in s) for stepping a stepper. M240 triggers a camera by emulating a Canon RC-1 Remote Data as described on this site. // Filament Unload does a Retract, Delay, and Purge first: #define FILAMENT_UNLOAD_PURGE_RETRACT 13 // (mm) Unload initial retract length.

By default Marlin assumes you have a buzzer with a fixed frequency. #define E3_AUTO_FAN_PIN -1 I have tried changing MAX_FEEDRATE , MAX_ACCELERATION , HOMING_FEEDRATE . This option specifies the kickstart duration in milliseconds. See Configuration_adv.h for the full set of sub-options. In print/travel moves, DEFAULT_ACCELERATION and DEFAULT_TRAVEL_ACCELERATION apply to the XYZ axes. Enables the use of Hephestos 2 24V heated bed. Some hosts use a proportional font in their output console. In the procedure known as homing, each axis is moved towards one end until the endstop switch is triggered, at which point the machine knows that the axis is at the endstop (home) position. If the buffer is too small at runtime, input shaping will have reduced effectiveness during high speed movements. These options specify the inset, grid, and 3-point triangle to use for UBL. * Power is stored in move blocks and applied when blocks are processed by the Stepper ISR. If any sensor goes below the minimum temperature set here, Marlin will shut down the printer with a MINTEMP error. Zero Vibration (ZV) Input Shaping for X and/or Y movements. #define FTM_SHAPING_DEFAULT_X_FREQ 37.0f // (Hz) Default peak frequency used by input shapers. Slows down the machine when the look ahead buffer is filled to the set SLOWDOWN_DIVISOR amount. Files sliced with SkeinForge contain the wrong arc G-codes when using Arc Point as fillet procedure. The Dual X-Carriage design allows the inactive extruder to be parked to keep oozing filament away from the print, reduces the weight of each carriage, and enables faster printing speeds. * e.g., 'M3 I' enables continuous inline power which is processed by the planner. #define PREHEAT_2_TEMP_BED 110 #define FTM_STEPPER_FS 20000 // (Hz) Frequency for stepper I/O update.

Probes can share the Z min plug, or can use one or more of the extra connectors.
