Since my proximity sensor is placed right of the extruder, see the attached picture, I had to limit the X_MAX_POS to 130. Crow0711. // … Left Z_AFTER_PROBING undefined, and commented out my defines of MANUAL_XYZ_HOME_POS. Did not make any changes to the (buggy!) The Y and Z axis retract the proper 4mm after homing. // - Prevent Z homing when the Z probe is outside bed area. Without this option enabled the nozzle will crash into the bed when homing. However, when I changed that definition to -1, the y axis would only move in 1 direction. // ENDSTOP SETTINGS: // Sets direction of endstops when homing; 1=MAX, -1=MIN #define X_HOME_DIR -1 #define Y_HOME_DIR 1 // - Move the Z probe (or nozzle) to a defined XY point before Z Homing when homing all axes (G28). After homing the 3d printer again, the Z axis will be updated, and the -2.5 position will become the new zero position. 2) Limits after homing Then I had to change the settings of the travel limits after homing. I usually use optical infrared sensors for my printers, but I wanted to try the BLTouch sensors since none had fallen yet by my hands. After changing these values, you must compile and upload the firmware again before continuing. // Travel limits after homing #define X_MAX_POS 227 // 227.81 MAX #define X_MIN_POS 0 #define Y_MAX_POS 180 // 190.96 MAX - 11 for clip #define Y_MIN_POS 0 #define Z_MAX_POS 190 #define Z_MIN_POS 0 DELTA should wait until all homing is done before setting the XYZ current_position to home, because homing is a single operation. Dans Marlin v1.1.9 d'origine avant ce "#define" il y a ces commentaires : // The Z probe minimum outer margin (to validate G29 parameters). v1.1h, custom, XY Homing 20190830. // - Prevent Z homing when the Z probe is outside bed area. I recently switched over to using a Piezo z-sensor (highly recommended!) If you send command G0 X100 Y100 does it move to center of the bed? #define Z_SAFE_HOMING. This is a good way to keep tabs on what you did for what reason. // - Prevent Z homing when the Z probe is outside bed area. After some measurement the I got the Z_PROBE_OFFSET_FROM_EXTRUDER -3.4. Im using RAMPS 1.4 on my Hypercube with Marlin 1.1.5. // - Allow Z homing only after X and Y homing AND stepper drivers still enabled. The nozzle now barely touch the bed when z=0. The exact same settings are used for the X and Y axis including microstepping. #define Y_HOME_DIR 1 . This is the moving speed of the axis when homing in [mm/min]. #define X_HOME_DIR -1 #define… For Core and Cartesian robots this applies one-to-one when an individual axis has been homed. The latest Marlin 2.0 handles the boundaries automatically and the below code is not needed anymore for the latest Marlin 2.0 version. Naturally you'll need to have your min endstops wired up or you'll have a machine crash when it tries looking for said min endstop. I have a Sunhokey Prusa I3 2015 Model and marlin firmware. If you’re using a BLTouch: Uncomment #define BLTOUCH_DELAY and change from 500 to 200.This reduces the pause after each individual probe. Configuring Endstops on Ramps 1.4 With Marlin Firmware - @section Homing : This is going to be a, hopefully, complete tutorial on configuring endstops on 3D printers build on Ramps 1.4 using Marlin firmware.I am going to use Pronterface/Printrun host program to connect to my printer and issue terminal commands (G-codes). [#4398], [#4400] : Sanity checking of safe homing, temp sensors [#4414] : Remove all #include from Configuration.h / Configuration_adv.h; Homing and Bed Leveling [#3707] : Fix curved movements in G29 for Delta [#3775] : Report current position to host after G29 [#3782] : Require homing … // - Move the Z probe (or nozzle) to a defined XY point before Z Homing when homing all axes (G28). Use homing sequence with preheat as these allow to set a probing position as well that would allow activating z probe. I realized that this is because the HOMEAXIS function sets the current position to 0, and then moves to the current position. <=> La marge extérieure minimale du palpeur Z (pour valider les paramètres G29). Set an axis' current position to its home position (after homing). The stepper motor receives step by step moving command from the controller. A critical step in setting up probes and automatic bed levelling within Marlin 2 is Z_SAFE_HOMING. At home position, the sensor is out of the aluminum bed so I have to put some aluminum tape underneath the glass. ... (last value) is the stowed position for the Z probe. The M208 limits set the position immediately after the corresponding G1 S1 command completes by triggering the homing switch. #define Z_AFTER_PROBING 5. // - If stepper drivers time out, it will need X and Y homing again before Z homing. Homing feed rate. This firmware was compiled with some changes to file config.h to perform homing only on XY and to set “zero” after homing cycle. G1 Z3 F5000: Raises the Z position up 3 mm relative to where it was (G1 tells the machine to move, Z3 tells it how much to move and along which axis, F5000 is the speed of movement) G92 Z0.3: Treats the current position as Z = 0.3 (applying an offset of -0.3 and creating a sort of false home for the Z-axis). We have three MAX limit switches at the HOME position, our settings are as follows: // Sets direction of endstops when homing; 1=MAX, -1=MIN . After I send the G28 command the printer will home X and Y axis but while homing Z axis for first time the Y … // - Allow Z homing only after X and Y homing AND stepper drivers still enabled. Configurar Marlin 2.0.x en tu impresora puede parecer un reto a simple vista y algo que solamente programadores avezados pueden conseguir.Pero esa afirmación no puede estar más lejos de la realidad, créeme. // - Allow Z homing only after X and Y homing AND stepper drivers still enabled. 2.
