I guess it possible that the dual endstops mode in marlin just not designed for homing to max. Not available for Cyrillic, Kana, Turkish, Greek, or Chinese. // Western only. Just to confirm this is in the Configuration_adv.h folder? I had similar grinding motors at the endstop due to limit switches on the wrong axis. That's a completely different story, not … #define Z_HOME_BUMP_MM 2. Look for a subsection of Z Probe Options called "section homing". Marlin features. Press question mark to learn the rest of the keyboard shortcuts. Configuring Marlin firmware in Arduino IDE Open the Configuration.h file/sketch/tab and scroll Down to the @section homing - around line 330 or so. It is worth noting I have no programming experience so I'm likely missing something obvious. Hello, I uploaded marlin firmware to my arduino mega that uses ramps 1.4, and my printer will not home correctly. Costs 2300 bytes of PROGMEM. This feature is so sensitive that it can actually take the place of traditional endstops. If I'm just moving the axis in the + direction, it works fine, but when trying to move in the - direction, even when not at X=0mm, it claims the endstop was hit. Edit: added screenshot of configuration file. report. But it then goes to the center of the bed. Marlin works on almost every type of printer and not … kill() called! Full rules are in the "r/ender3 Rules" widget in the sidebar above this. Press J to jump to the feed. I’ve successfully tested every possible combination of M119. I made sure it homes to the min direction while it is programmed to home to the Y_MIN_PLUG. I'm now trying to change the firmware to add in the offsets of y: -10.1 and x offset: -45.7 (for the BLtouch mount). Editing Marlin Firmware I assume it’s somewhere in the code. I edited all the settings I knew about adjusting such as thermistor values, but I couldn't find the stepper motor settings with ctrl f. Bear in mind Im using 400 step, 0.9 degree Nema 17's and DRV8825 drivers, with a 20 tooth GT2 belt, hence the 320 steps per X and Y... yours most likely will be different. 2. have to press the button repeatedly till it hits the endstop, where it bounces back as it should. Same wiring, same pins definition, with older marlin it works and homing to y-min is working with newer marlin not. Don't confuse that with Sensorless probing. This means the system needs first to establish its starting point of the physical (machine) coordinate system, a process called Homing. Description. Does anyone have any ideas on how to fix this? The state of the Z probe and filament runout sensors are also reported with this command. Now the printer seems to be of two minds when it comes to finding the origin. 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. https://github.com/bigtreetech/BIGTREETECH-SKR-mini-E3/issues/257#issuecomment-632865653. 3d printer not homing correctly Answered Hello, I uploaded marlin firmware to my arduino mega that uses ramps 1.4, and my printer will not home correctly. #define HOMING_BUMP_MM { 5, 5, 2 } But if you use the latest configuration files as the baseline and apply your changes to that, then you won't get errors. Change (or reverse the motor connector) if an axis goes the wrong way.#define INVERT_X_DIR false#define INVERT_Y_DIR true#define INVERT_Z_DIR false. If it switch the motor polarity, it will not go to the endstop. #define SERVO0_PIN 27 is not required to set up your BLTouch in Marlin 2.x, as it’s defined in the pins folder by default; You’ll need to customize the offset between Probe and Extruder. By using our Services or clicking I agree, you agree to our use of cookies. As far as I'm aware I am using the latest configuration files. the leds on my BTT GTR board view the trigger state of the switches, which always worked fine and the correct behavior. Homing is the process where the machine finds all the limits of the 3 axis (at the endstop switches), to have a common reference point for each axis. As a side-effect, X and Y homing are required before Z homing. With the last bugfix : 6a2a10a and when issuing a G28 or using the LCD option to home the printer, I get a Homing Failed / PRINTER HALTED. But if you use the latest configuration files as the baseline and apply your changes to that, then you won't get errors. By always I also mean when homing. If homing is needed the LCD will blink the X Y Z indicators. Is it possible to fix via the LCD or … On pronterface, I get: SENDING:G28 Error:Printer halted. It is homing towards the endstop. mikej (Michael J) November 23, 2019, 10:37am #8. When I hit home in repetier host, the axis moves a centimeter. Homing feed rate. //=============================================================================//============================== Movement Settings ============================//=============================================================================// @section motion/** * Default Settings * * These settings can be reset by M502 * * Note that if EEPROM is enabled, saved values will override these. XYZ_CONSTS(float, home_bump_mm, HOME_BUMP_MM); Marlin/src/module/motion.cpp:77:71: note: suggested alternative: 'HOMING_BUMP_MM', Marlin/src/module/motion.cpp:77:80: error: 'Y_HOME_BUMP_MM' was not declared in this scope, Compiling .pio/build/STM32F103RC_btt_512K/src/src/module/stepper/trinamic.cpp.o, Marlin/src/module/motion.cpp:77:80: note: suggested alternative: 'HOMING_BUMP_MM', Marlin/src/module/motion.cpp:77:89: error: 'Z_HOME_BUMP_MM' was not declared in this scope, Marlin/src/module/motion.cpp:77:89: note: suggested alternative: 'HOMING_BUMP_MM', Compiling .pio/build/STM32F103RC_btt_512K/src/src/module/temperature.cpp.o, *** [.pio/build/STM32F103RC_btt_512K/src/src/module/motion.cpp.o] Error 1. I am not using it as a Z-stop currently. This gramatically and logically indeed falls under previous line, but look at … If stepper drivers time out, X and Y homing will be required again. Currently it's homing to X125.0, Y129.0, 000.8. While this is only used for volumetric extrusions. Additionally the next option to configure in the setting up Marlin 2 with the SKR V1.4 and the Configuration file, is the default nominal filament diameter. Not sure what I have screwed up. *//** * With this option each E stepper can have its own factors for the * following movement settings. Marlin can use this to automatically reduce the driver current if your steppers overheat for some reason. // #define USE_BIG_EDIT_FONT // A smaller font may be used on the Info Screen. In Marlin 2.x, they’re now combined in NOZZLE_TO_PROBE_OFFSET. How can I set the home position in marlin to X0,Y0,Z0? Message the mods before posting any sales links/affiliate links. Z Safe Homing prevents Z from homing when the probe (or nozzle) is outside bed area by moving to a defined XY point (by default, the middle of the bed) before Z Homing when homing all axes with G28. The stepper motor receives step by step moving command from the controller. Homing XY moves to the lower left as it always has, but homing Z moves not only to Z=0, but also to the center of the build plate. Looking for a BIG marlin setup: I can't deal with Duet3d anymore, reprap firmware is as stable as a unicycle. save. hide. The forums are retiring in 2021 and are now closed for new topics and comments. Is using Visual Studio with Marlin 2.0 to change the setting, "NOZZLE_TO_PROBE_OFFSET", compile and save the firmware.bin to my SD card the best way to change that setting? Try using Pronterface via usb to see if its repetier causing problems. Then it was a question of reversing one direction in my firmware due to the motor going the wrong way. The printer is unusable. I installed a BLTouch bed leveling probe on my printer which uses Marlin 2.0.5.3. This is the moving speed of the axis when homing in [mm/min]. 2.0.5. Lately the new electronic boards of the company BigTreeTech (SKR V1.4 and SKR 1.4 Turbo) are enjoying quite a notoriety within the world of 3D printing. I left those values at the default since it is moving in the right direction. When the X-endstop is not inverted, homing only makes the axis progress a bit, similar to what @emartinez167 ran into with Issue #1725. However, this is not so straightforward to achieve with Marlin - there is ENDSTOPS_ALWAYS_ON_DEFAULT in Configuration_adv.h, however look at the following line. It could be both hardware and firmware related problems. Support for Cartesian, Delta, SCARA, and Core/H-Bot kinematics. *///#define DISTINCT_E_FACTORS/** * Default Axis Steps Per Unit (steps/mm) * Override with M92 * X, Y, Z, E0 [, E1[, E2[, E3[, E4]]]] */#define DEFAULT_AXIS_STEPS_PER_UNIT { 320, 320, 1600, 378 }. From the endstops, firmware defined values exist to give the printer head the offset to the home position, also known as origin (X=0, Y=0). Why not install a leveling sensor to level at a single central point in the bed (SAFE_HOMING), and let Marlin generate the mesh of points and worry about the rest? I use M119 and all the endstop read open, then they were triggered as I triggered them. Cookies help us deliver our Services. Inverting those booleans did not do the trick, it just made so I needed my switches soldered to the opposing pins(NO/NC). I previously had an issue which was fixed with this workaround - https://github.com/bigtreetech/BIGTREETECH-SKR-mini-E3/issues/257#issuecomment-632865653, This seems to allow the compile to progress further but I am now getting the following errors, Marlin/src/module/motion.cpp:77:71: error: 'X_HOME_BUMP_MM' was not declared in this scope, #define XYZ_CONSTS(T, NAME, OPT) const PROGMEM XYZval NAME##_P = { X_##OPT, Y_##OPT, Z_##OPT }, Marlin/src/module/motion.cpp:83:1: note: in expansion of macro 'XYZ_CONSTS'. 1 comment. 3 years ago. If fewer factors are given than the * total number of extruders, the last value applies to the rest. [ERROR] Error:Printer halted. // #define USE_SMALL_INFOFONT // Enable this option and reduce the value to optimize screen updates. If you dont see “LEFT_PROBE_BED_POSITION” defined in your configuration.h file then you have a Marlin version that does not need this code below. And it is not surprising, since they have perfectly understood the “Maker” movement and have adapted to … Y_MIN triggers when I hold it down. Moreover by default the nominal filament diameter is set to 3.0mm. have to press the button repeatedly till it hits the endstop, where it bounces back as it should. I've just checked and my homing bump is set to { 5, 5, 2 } like you've said. In Marlin 1.x, this was done with X, Y, and Z_PROBE_OFFSET_FROM_EXTRUDER. I'll try going through the guide, New comments cannot be posted and votes cannot be cast. Now, a bit below that, around line 2324, I'm enabling SENSORLESS_HOMING. Usually you tell the firmware that home direction is either negative or positive. #define X_HOME_BUMP_MM 5. Not available for Cyrillic, Kana, Turkish, Greek, or Chinese. G28 disables bed leveling. changed the microswitch behavior for testing and it's the same problem. A sub-reddit for the users of the Creality Ender 3 3D printer. So, the arduino realizes it hit the endstop, but does not act according to that. Use this command to set the bump sensitivity for the X, Y, and Z stepper drivers. kill() called! Use this command to get the current state of all endstops, useful for setup and troubleshooting. Bugfix, later 2.0.6. Make sure you do not have 2 // in front of #define … #define Y_HOME_BUMP_MM 5. Setting up Marlin 2.x.x on my first time CoreXY Hypercube build and where do you establish "home" in configuration.h . When I hit home in repetier host, the axis moves a centimeter. NOTE: The latest Marlin 2.0 handles the boundaries automatically and the below code is not needed anymore for the latest Marlin 2.0 version. Marlin has some g-code support which is useful to tune, test, and run your printer. Marlin indicates this by blinking question-marks in place of X, Y and Z on the LCD screen (v1.1.8 and older) or blinking ‘?’ in place of the coordinates besides X,Y and Z (Marlin v1.1.9 / v2.0.0 and newer). Im using RAMPS 1.4 on my Hypercube with Marlin 1.1.5. Please be friendly and helpful. share. 2. When I do a G28 to test the print head goes as expected to the front left of the print bed. Endstops are reported as either “open” or “TRIGGERED”. You can't just upload a firmware without adjusting the parameter to your machine - this includes homing direction, endstop location and logic as well as the stepping and speeds for the motors.Since I have no clue what version of Marlin you use I suggest you visit their Wiki or check documentation.I hope you did write the original values of machine down somewhere....
