Looking for a BIG marlin setup: I can't deal with Duet3d anymore, reprap firmware is as stable as a unicycle. Hello, I uploaded marlin firmware to my arduino mega that uses ramps 1.4, and my printer will not home correctly. But if you use the latest configuration files as the baseline and apply your changes to that, then you won't get errors. Editing Marlin Firmware I assume it’s somewhere in the code. changed the microswitch behavior for testing and it's the same problem. Not available for Cyrillic, Kana, Turkish, Greek, or Chinese. #define HOMING_FEEDRATE {50*60, 50*60, 4*60} Axis steps per unit. Use this command to get the current state of all endstops, useful for setup and troubleshooting. // #define USE_SMALL_INFOFONT // Enable this option and reduce the value to optimize screen updates. 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. 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. 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. Just to confirm this is in the Configuration_adv.h folder? I use M119 and all the endstop read open, then they were triggered as I triggered them. But it then goes to the center of the bed. hide. Full rules are in the "r/ender3 Rules" widget in the sidebar above this. 1 comment. And it is not surprising, since they have perfectly understood the “Maker” movement and have adapted to … 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. Now the printer seems to be of two minds when it comes to finding the origin. The printer is unusable. Oftentimes in Marlin, speed or acceleration are expressed in [mm/s] or [mm/s2] but the feed is expressed in [mm/min]. How can I set the home position in marlin to X0,Y0,Z0? // @section machine// Invert the stepper direction. Currently it's homing to X125.0, Y129.0, 000.8. Use this command to set the bump sensitivity for the X, Y, and Z stepper drivers. [ERROR] Error:Printer halted. // Western only. kill() called! // #define USE_BIG_EDIT_FONT // A smaller font may be used on the Info Screen. Homing feed rate. 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. A sub-reddit for the users of the Creality Ender 3 3D printer. Marlin has some g-code support which is useful to tune, test, and run your printer. 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. I made sure it homes to the min direction while it is programmed to home to the Y_MIN_PLUG. 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. Is it possible to fix via the LCD or … The forums are retiring in 2021 and are now closed for new topics and comments. I guess it possible that the dual endstops mode in marlin just not designed for homing to max. Follow with M420 S to turn leveling on, or use RESTORE_LEVELING_AFTER_G28 to automatically keep leveling on after G28. It is worth noting I have no programming experience so I'm likely missing something obvious. Homing is required before G29, M48, and some other procedures.. This is the moving speed of the axis when homing in [mm/min]. #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. If it switch the motor polarity, it will not go to the endstop. That’s what Marlin is … I had similar grinding motors at the endstop due to limit switches on the wrong axis. 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'. Notes. That's a completely different story, not … Bugfix, later 2.0.6. I'll try going through the guide, New comments cannot be posted and votes cannot be cast. //=============================================================================//============================== Movement Settings ============================//=============================================================================// @section motion/** * Default Settings * * These settings can be reset by M502 * * Note that if EEPROM is enabled, saved values will override these. Don't confuse that with Sensorless probing. If homing is needed the LCD will blink the X Y Z indicators. As a side-effect, X and Y homing are required before Z homing. Not sure what I have screwed up. This means the system needs first to establish its starting point of the physical (machine) coordinate system, a process called Homing. I left those values at the default since it is moving in the right direction. When I do a G28 to test the print head goes as expected to the front left of the print bed. #define X_HOME_BUMP_MM 5. Full-featured G-code with over 150 commands. 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. By always I also mean when homing. Y_MIN triggers when I hold it down. Nonetheless it is still not a bad thing to change this to 1.75mm. 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). If fewer factors are given than the * total number of extruders, the last value applies to the rest. Edit: added screenshot of configuration file. I've just checked and my homing bump is set to { 5, 5, 2 } like you've said. Inverting those booleans did not do the trick, it just made so I needed my switches soldered to the opposing pins(NO/NC). The stepper motor receives step by step moving command from the controller. When I hit home in repetier host, the axis moves a centimeter. As far as I'm aware I am using the latest configuration files. Message the mods before posting any sales links/affiliate links. *///#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 }. 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? kill() called! Same wiring, same pins definition, with older marlin it works and homing to y-min is working with newer marlin not. 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. Description. Marlin can use this to automatically reduce the driver current if your steppers overheat for some reason. Try using Pronterface via usb to see if its repetier causing problems. Support for Cartesian, Delta, SCARA, and Core/H-Bot kinematics. Marlin works on almost every type of printer and not … report. mikej (Michael J) November 23, 2019, 10:37am #8. #define Z_HOME_BUMP_MM 2. 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. Then it was a question of reversing one direction in my firmware due to the motor going the wrong way. I installed a BLTouch bed leveling probe on my printer which uses Marlin 2.0.5.3. #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. It is homing towards the endstop. Where do I fix this in the firmware? In Marlin 1.x, this was done with X, Y, and Z_PROBE_OFFSET_FROM_EXTRUDER. Posted by 6 days ago. #define Y_HOME_BUMP_MM 5. 2. When the X-endstop is not inverted, homing only makes the axis progress a bit, similar to what @emartinez167 ran into with Issue #1725. Some TMC stepper drivers can detect when they bump into something that causes them to stop moving. *//** * With this option each E stepper can have its own factors for the * following movement settings. 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. Not available for Cyrillic, Kana, Turkish, Greek, or Chinese. Usually you tell the firmware that home direction is either negative or positive. Setting up Marlin 2.x.x on my first time CoreXY Hypercube build and where do you establish "home" in configuration.h . Now, a bit below that, around line 2324, I'm enabling SENSORLESS_HOMING. This feature is so sensitive that it can actually take the place of traditional endstops. https://github.com/bigtreetech/BIGTREETECH-SKR-mini-E3/issues/257#issuecomment-632865653. 3 years ago. 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. While this is only used for volumetric extrusions. The state of the Z probe and filament runout sensors are also reported with this command. Costs 2300 bytes of PROGMEM. Look for a subsection of Z Probe Options called "section homing". Moreover by default the nominal filament diameter is set to 3.0mm. 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? the leds on my BTT GTR board view the trigger state of the switches, which always worked fine and the correct behavior. If stepper drivers time out, X and Y homing will be required again. have to press the button repeatedly till it hits the endstop, where it bounces back as it should. 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. 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. 2.0.5. Press J to jump to the feed. Endstops are reported as either “open” or “TRIGGERED”. I am not using it as a Z-stop currently. I’ve successfully tested every possible combination of M119. Marlin features. 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). Please be friendly and helpful. 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). 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.... Answer 2. 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. So, the arduino realizes it hit the endstop, but does not act according to that. On pronterface, I get: SENDING:G28 Error:Printer halted. save. This gramatically and logically indeed falls under previous line, but look at … Make sure you do not have 2 // in front of #define … 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. Does anyone have any ideas on how to fix this? Im using RAMPS 1.4 on my Hypercube with Marlin 1.1.5. have to press the button repeatedly till it hits the endstop, where it bounces back as it should. It could be both hardware and firmware related problems. Switches, which always worked marlin not homing and the correct behavior the bed called homing can have its factors.
