Forenliste Themenübersicht Neues Thema. // - Move the Z probe (or nozzle) to a defined XY point before Z Homing when homing all axes (G28). I have a Sunhokey Prusa I3 2015 Model and marlin firmware. // - Prevent Z homing when the Z probe is outside bed area. // - Allow Z homing only after X and Y homing AND stepper drivers still enabled. Then we need to set up the dimensions of movement after the startup in the HOME position. The Marlin firmware is built using the Arduino IDE (Integrated Development Environment). If you’re using a BLTouch: Uncomment #define BLTOUCH_DELAY and change from 500 to 200.This reduces the pause after each individual probe. Beim Homing allerdings fahren die Motoren von X und Y in die falsche Richtung. After changing these values, you must compile and upload the firmware again before continuing. 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. So search and enable Z_SAFE_HOMING if using a BlTouch or probe. // - If stepper drivers time out, it will need X and Y homing again before Z homing. Go to step 7 to test the new settings. G28 code. #define Z_HOME_DIR 1 . #define Y_HOME_DIR 1 . // - Prevent Z homing when the Z probe is outside bed area. 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 . // - If stepper drivers time out, it will need X and Y homing again before Z homing. (It loops after this, which is kind of nice if you accidentally put weight on the bed.) The nozzle now barely touch the bed when z=0. @section extras The steps/mm are correct on all axis. After homing the 3d printer again, the Z axis will be updated, and the -2.5 position will become the new zero position. // - Move the Z probe (or nozzle) to a defined XY point before Z Homing when homing all axes (G28). A critical step in setting up probes and automatic bed levelling within Marlin 2 is Z_SAFE_HOMING. So I got down to work for Configure BLTouch with BabyStepping in the last Marlin available today and satiate my curiosity.. Without this option enabled the nozzle will crash into the bed when homing. Im using RAMPS 1.4 on my Hypercube with Marlin 1.1.5. Will not recalculate the zero return again unless the power is turned completely off at main breaker then back on. After I send the G28 command the printer will home X and Y axis but while homing Z axis for first time the Y … // - If stepper drivers time out, it will need X and Y homing again before Z homing. Long time reader, first time poster Hello guys, I'm having some issues configuring my Auto bed leveling settings in Marlin. However, when I changed that definition to -1, the y axis would only move in 1 direction. The stepper motor receives step by step moving command from the controller. I realized that this is because the HOMEAXIS function sets the current position to 0, and then moves to the current position. Das passiert auch, wenn ich die Vorzeichen ändere. Introducción. geschrieben von Crow0711 . I verified this using the M114 function. 2) Limits after homing Then I had to change the settings of the travel limits after homing. Set an axis' current position to its home position (after homing). // - Allow Z homing only after X and Y homing AND stepper drivers still enabled. // - Move the Z probe (or nozzle) to a defined XY point before Z Homing when homing all axes (G28). 2. Crow0711. My bed has this dimensions: Quote// Travel limits after homing #define X_MAX_POS 190 #define X_MIN_POS 18 … The following must be performed immediately and without homing the printer. #define HOMING_FEEDRATE {50*60, 50*60, 4*60} Axis steps per unit. Arduino 0023 IDE – showing line number location For Marlin Firmware V1 you will need Arduino 0023 IDE to save, compile and upload to the 3d printer motherboard. 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. <=> La marge extérieure minimale du palpeur Z (pour valider les paramètres G29). 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. #define Z_AFTER_PROBING 5. This firmware was compiled with some changes to file config.h to perform homing only on XY and to set “zero” after homing cycle. ... (last value) is the stowed position for the Z probe. Die Bewegungsrichtung stimmt bei der Bedienung der Maschinensteuerung bei allen Achsen. 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). // 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 #define Z_AFTER_HOMING 5. The exact same settings are used for the X and Y axis including microstepping. For Core and Cartesian robots this applies one-to-one when an individual axis has been homed. However, after running auto bed leveling (G29), the z now is +5 at the same position above when … [#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 … #define X_HOME_DIR -1 #define… DELTA should wait until all homing is done before setting the XYZ current_position to home, because homing is a single operation. At home position, the sensor is out of the aluminum bed so I have to put some aluminum tape underneath the glass. I was hoping someone could help me. This firmware comes from master branch of gnea/grbl aligned to the commit of 30 august 2019. G1 X0 Y0 F2400 ; move to the X=0 Y=0 position on the bed at a speed of 2400 mm/min G1 Z10 F1200 ; move the Z-axis to Z=10mm at a slower speed of 1200 mm/min G1 X30 E10 F1800 ; push 10mm of filament into the nozzle while moving to the X=30 position at the same time // 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 If you dont see “LEFT_PROBE_BED_POSITION” defined in your configuration.h file then you have a Marlin version … // - 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. 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). T… 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. 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. Left Z_AFTER_PROBING undefined, and commented out my defines of MANUAL_XYZ_HOME_POS. 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. 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. Since my proximity sensor is placed right of the extruder, see the attached picture, I had to limit the X_MAX_POS to 130. // ENDSTOP SETTINGS: // Sets direction of endstops when homing; 1=MAX, -1=MIN #define X_HOME_DIR -1 #define Y_HOME_DIR 1 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). 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). //#define Z_SAFE_HOMING Use homing sequence with preheat as these allow to set a probing position as well that would allow activating z probe. Configuration_adv.h. This is the moving speed of the axis when homing in [mm/min]. NOTE: Remember switched machines after the initial zero return. I just enabled Auto leveling with inductive sensor. Pro-tip: Note how I place // after the mm input and then write notes. If you send command G0 X100 Y100 does it move to center of the bed? // - Prevent Z homing when the Z probe is outside bed area. Oftentimes in Marlin, speed or acceleration are expressed in [mm/s] or [mm/s2] but the feed is expressed in [mm/min]. Hi.. This is pretty quick. As described previously, homing (after inverting the Y axis and changing Y_HOM_DIR to 1) would result in no motion. // … The latest Marlin 2.0 handles the boundaries automatically and the below code is not needed anymore for the latest Marlin 2.0 version. The Y and Z axis retract the proper 4mm after homing. I recently switched over to using a Piezo z-sensor (highly recommended!) Eeprom is disabled so it's not a stored Eeprom value. Marlin Config.h Endstop Home Position anfahren 22. Part 7. Open the new Marlin/Configuration_adv.h file in your chosen text editor.. Baby stepping allows the nozzle to move a tiny amount without changing the recorded coordinates for the hot-end. 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. Recently a colleague sent me a BLTouch / 3DTouch sensor from the Geeetech brand. v1.1h, custom, XY Homing 20190830. Only then it will recalculate the zero return. Homing feed rate. Did not make any changes to the (buggy!) // - Allow Z homing only after X and Y homing AND stepper drivers still enabled. To measure it gets activated and if that means move extruder left and you are at x=0 this is not possible-> illegal position. The Marlin firmware guide is likely to be updated to improve the information where necessary after publishing. The M208 limits set the position immediately after the corresponding G1 S1 command completes by triggering the homing switch. I set auto leveling grid for 4 corners of the bed. Also Keep in mind if you move switch or dog your zero return position will change and you may need to do a gridshift. // - Allow Z homing only after X and Y homing AND stepper drivers still enabled. // - Move the Z probe (or nozzle) to a defined XY point before Z Homing when homing all axes (G28). #define X_HOME_DIR 1 . After some measurement the I got the Z_PROBE_OFFSET_FROM_EXTRUDER -3.4. 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.
