Homing feed rate. // - Prevent Z homing when the Z probe is outside bed area. #define X_HOME_DIR -1 #define… Part 7. // - 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. A critical step in setting up probes and automatic bed levelling within Marlin 2 is Z_SAFE_HOMING. My distance after homing for the X axis is set for 4mm but retracts 70mm while the Y and Z axis retract the proper 4mm. geschrieben von Crow0711 . // - Move the Z probe (or nozzle) to a defined XY point before Z Homing when homing all axes (G28). Recently a colleague sent me a BLTouch / 3DTouch sensor from the Geeetech brand. // - Allow Z homing only after X and Y homing AND stepper drivers still enabled. NOTE: Remember switched machines after the initial zero return. The exact same settings are used for the X and Y axis including microstepping. Configuration_adv.h. The M208 limits set the position immediately after the corresponding G1 S1 command completes by triggering the homing switch. Also Keep in mind if you move switch or dog your zero return position will change and you may need to do a gridshift. // - If stepper drivers time out, it will need X and Y homing again before Z homing. At home position, the sensor is out of the aluminum bed so I have to put some aluminum tape underneath the glass. Will not recalculate the zero return again unless the power is turned completely off at main breaker then back on. Marlin Config.h Endstop Home Position anfahren. Oftentimes in Marlin, speed or acceleration are expressed in [mm/s] or [mm/s2] but the feed is expressed in [mm/min]. 2) Limits after homing Then I had to change the settings of the travel limits after homing. This is pretty quick. If you dont see “LEFT_PROBE_BED_POSITION” defined in your configuration.h file then you have a Marlin version … Only then it will recalculate the zero return. The Marlin firmware guide is likely to be updated to improve the information where necessary after publishing. Das passiert auch, wenn ich die Vorzeichen ändere. 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. See this section of the Marlin Configuration.h file: The Y direction says 1, thus it is set to home towards the MAX, not the MIN. // - Move the Z probe (or nozzle) to a defined XY point before Z Homing when homing all axes (G28). I was hoping someone could help me. Die Bewegungsrichtung stimmt bei der Bedienung der Maschinensteuerung bei allen Achsen. Did not make any changes to the (buggy!) // - Allow Z homing only after X and Y homing AND stepper drivers still enabled. However, if your homing file has a G92 command after the G1 S1 command (as is typically the case when homing to a Z-min switch), then the G92 command will override that position. If you send command G0 X100 Y100 does it move to center of the bed? Left Z_AFTER_PROBING undefined, and commented out my defines of MANUAL_XYZ_HOME_POS. T… // - Move the Z probe (or nozzle) to a defined XY point before Z Homing when homing all axes (G28). G28 code. Use homing sequence with preheat as these allow to set a probing position as well that would allow activating z probe. ... (last value) is the stowed position for the Z probe. Long time reader, first time poster Hello guys, I'm having some issues configuring my Auto bed leveling settings in Marlin. Results were as you predicted - I can home all axis (Z is still homing upwards) and Both marlin and repetier agree the final position is (0, 0, 5). Hi.. This firmware was compiled with some changes to file config.h to perform homing only on XY and to set “zero” after homing cycle. #define HOMING_FEEDRATE {50*60, 50*60, 4*60} Axis steps per unit. This is a good way to keep tabs on what you did for what reason. Introducción. #define Z_HOME_DIR 1 . Pro-tip: Note how I place // after the mm input and then write notes. v1.1h, custom, XY Homing 20190830. <=> La marge extérieure minimale du palpeur Z (pour valider les paramètres G29). DELTA should wait until all homing is done before setting the XYZ current_position to home, because homing is a single operation. To measure it gets activated and if that means move extruder left and you are at x=0 this is not possible-> illegal position. //#define Z_SAFE_HOMING Beim Homing allerdings fahren die Motoren von X und Y in die falsche Richtung. // 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 Since my proximity sensor is placed right of the extruder, see the attached picture, I had to limit the X_MAX_POS to 130. 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). // - Prevent Z homing when the Z probe is outside bed area. I just enabled Auto leveling with inductive sensor. #define Y_HOME_DIR 1 . 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. 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). 2. I verified this using the M114 function. I recently switched over to using a Piezo z-sensor (highly recommended!) The nozzle now barely touch the bed when z=0. I realized that this is because the HOMEAXIS function sets the current position to 0, and then moves to the current position. If you’re using a BLTouch: Uncomment #define BLTOUCH_DELAY and change from 500 to 200.This reduces the pause after each individual probe. #define Z_SAFE_HOMING. I have a Sunhokey Prusa I3 2015 Model and marlin firmware. // ENDSTOP SETTINGS: // Sets direction of endstops when homing; 1=MAX, -1=MIN #define X_HOME_DIR -1 #define Y_HOME_DIR 1 After homing the 3d printer again, the Z axis will be updated, and the -2.5 position will become the new zero position. // - Prevent Z homing when the Z probe is outside bed area. Marlin Config.h Endstop Home Position anfahren 22. and TMC2130 drivers with sensorless homing and with this, I gained a big area of my probable print bed compared to my previous BL Touch + stock driver setup. The Marlin firmware is built using the Arduino IDE (Integrated Development Environment). However, after running auto bed leveling (G29), the z now is +5 at the same position above when … The stepper motor receives step by step moving command from the controller. Forenliste Themenübersicht Neues Thema. 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). // - If stepper drivers time out, it will need X and Y homing again before Z homing. Crow0711. After changing these values, you must compile and upload the firmware again before continuing. // - Move the Z probe (or nozzle) to a defined XY point before Z Homing when homing all axes (G28). // - If stepper drivers time out, it will need X and Y homing again before Z homing. 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. (It loops after this, which is kind of nice if you accidentally put weight on the bed.) #define Z_AFTER_PROBING 5. This is the moving speed of the axis when homing in [mm/min]. After some measurement the I got the Z_PROBE_OFFSET_FROM_EXTRUDER -3.4. Then we need to set up the dimensions of movement after the startup in the HOME position. Without this option enabled the nozzle will crash into the bed when homing. // - If stepper drivers time out, it will need X and Y homing again before Z homing. @section extras // - Allow Z homing only after X and Y homing AND stepper drivers still enabled. If it does then nothing further is needed unless you want it to home Z over the bed after X and Y home then uncomment #define Z_SAFE_HOMING in configuration.h of the Marlin firmware and upload it to your board. Eeprom is disabled so it's not a stored Eeprom value. Go to step 7 to test the new settings. Baby stepping allows the nozzle to move a tiny amount without changing the recorded coordinates for the hot-end. // - Prevent Z homing when the Z probe is outside bed area. I set auto leveling grid for 4 corners of the bed. // Travel limits after homing #define X_MAX_POS 130 #define X_MIN_POS 0 #define Y_MAX_POS 110 #define Y_MIN_POS 0 #define Z_MAX_POS 100 So I got down to work for Configure BLTouch with BabyStepping in the last Marlin available today and satiate my curiosity..
