This is the moving speed of the axis when homing in [mm/min]. I have a Sunhokey Prusa I3 2015 Model and marlin firmware. I realized that this is because the HOMEAXIS function sets the current position to 0, and then moves to the current position. Pro-tip: Note how I place // after the mm input and then write notes. Part 7. I just enabled Auto leveling with inductive sensor. This firmware was compiled with some changes to file config.h to perform homing only on XY and to set “zero” after homing cycle. Go to step 7 to test the new settings. 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. #define HOMING_FEEDRATE {50*60, 50*60, 4*60} Axis steps per unit. #define X_HOME_DIR -1 #define… // - Allow Z homing only after X and Y homing AND stepper drivers still enabled. A critical step in setting up probes and automatic bed levelling within Marlin 2 is Z_SAFE_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. Die Bewegungsrichtung stimmt bei der Bedienung der Maschinensteuerung bei allen Achsen. 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. After I send the G28 command the printer will home X and Y axis but while homing Z axis for first time the Y … Homing feed rate. // - Move the Z probe (or nozzle) to a defined XY point before Z Homing when homing all axes (G28). 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. // ENDSTOP SETTINGS: // Sets direction of endstops when homing; 1=MAX, -1=MIN #define X_HOME_DIR -1 #define Y_HOME_DIR 1 //#define Z_SAFE_HOMING Marlin Config.h Endstop Home Position anfahren 22. I set auto leveling grid for 4 corners of the bed. Das passiert auch, wenn ich die Vorzeichen ändere. I verified this using the M114 function. However, after running auto bed leveling (G29), the z now is +5 at the same position above when … // - Move the Z probe (or nozzle) to a defined XY point before Z Homing when homing all axes (G28). Oftentimes in Marlin, speed or acceleration are expressed in [mm/s] or [mm/s2] but the feed is expressed in [mm/min]. Then we need to set up the dimensions of movement after the startup in the HOME position. Since my proximity sensor is placed right of the extruder, see the attached picture, I had to limit the X_MAX_POS to 130. Set an axis' current position to its home position (after homing). After some measurement the I got the Z_PROBE_OFFSET_FROM_EXTRUDER -3.4. Configuration_adv.h. Only then it will recalculate the zero return. 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 changing these values, you must compile and upload the firmware again before continuing. The Y and Z axis retract the proper 4mm after homing. 2. geschrieben von Crow0711 . (It loops after this, which is kind of nice if you accidentally put weight on the bed.) The steps/mm are correct on all axis. Recently a colleague sent me a BLTouch / 3DTouch sensor from the Geeetech brand. 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. However, when I changed that definition to -1, the y axis would only move in 1 direction. 2) Limits after homing Then I had to change the settings of the travel limits after homing. // - Allow Z homing only after X and Y homing AND stepper drivers still enabled. Also Keep in mind if you move switch or dog your zero return position will change and you may need to do a gridshift. I was hoping someone could help me. Left Z_AFTER_PROBING undefined, and commented out my defines of MANUAL_XYZ_HOME_POS. My bed has this dimensions: Quote// Travel limits after homing #define X_MAX_POS 190 #define X_MIN_POS 18 … #define Z_SAFE_HOMING. So I got down to work for Configure BLTouch with BabyStepping in the last Marlin available today and satiate my curiosity.. // - Move the Z probe (or nozzle) to a defined XY point before Z Homing when homing all axes (G28). G28 code. v1.1h, custom, XY Homing 20190830. // - If stepper drivers time out, it will need X and Y homing again before Z homing. // 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 // - Prevent Z homing when the Z probe is outside bed area. Without this option enabled the nozzle will crash into the bed when homing. Long time reader, first time poster Hello guys, I'm having some issues configuring my Auto bed leveling settings in Marlin. 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. 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.
