This means the system needs first to establish its starting point of the physical (machine) coordinate system, a process called Homing. I noticed this too on my K8200. G28 disables bed leveling. privacy statement. If your bed is non-standard, you’ll need to adjust the size and/or travel limits to make sure Marlin knows this. On machines that use Z-min for an endstop, the Z-Max pin is recommended next, so this is … Movement settings Define the number of axis. Thanks to #7470, #define ENDSTOPS_ALWAYS_ON_DEFAULT is always uncommented (enabled). Z-endstop is ignored while homing if using BLTouch probe despite the ENDSTOPS_ALWAYS_ON_DEFAULT is enabled. that solved my problem . I had to get a new board and with the original k8200 board didn't have this problem, New comments cannot be posted and votes cannot be cast. // For DELTA this is the top-center of the Cartesian print volume. Simulate the BLTouch malfunction or just mount the BLTouch probe too high - so the Z endstop switch will be triggered before the BLTouch probe (or just trigger it by hand before the BLTouch is triggered). This is the moving speed of the axis when homing in [mm/min]. It's certainly no physical hardship to have both probe and endstop installed - I suspect many users have the endstop from the factory and add a probe later - so this would provide a safety feature which becomes more applicable as more boards introduce a dedicated Z Probe pin, and takes advantage of hardware that many Marlin users will already have. Option 4 : most common setup and really identical functionally to 3 Without this option enabled the nozzle will crash into the bed when homing. #define Z_SAFE_HOMING. If stepper drivers time out, X and Y homing will be required again. In every step/combination, all other relevant configuration defines are shown for clarity. // Sets direction of endstops when homing; 1=MAX, -1=MIN #define X_HOME_DIR -1 #define Y_HOME_DIR -1 #define Z_HOME_DIR 1. As far as I can see there is only 1 actionable item here. Option 7 : Same configuration option needed from Option 2. However when homing Z the BLT probe signal was ignored every time & only the Z endpoint switch would conclude the homing. Making this fully functional and easily selectable is a wise idea. If homing is needed the LCD will blink the X Y Z indicators. And it is there that my issue began. In general, on deltabots the probe should be connected to the unused Z-Min endstop pin (if there is one). Discussion. It is not a major problem, you can change within the Marlin firmware and indicate that for Z- we are going to use the Z+, but you have to make unnecessary modifications. Press J to jump to the feed. Im using RAMPS 1.4 on my Hypercube with Marlin 1.1.5. Option 2 : Needs method to intentionally force off the endstop pin (use_zmin_plug disabled, home dir <1 probe pin set and probe enabled) - Bug Thanks to #7470, #define ENDSTOPS_ALWAYS_ON_DEFAULT is always uncommented (enabled). I have been struggling for a week with a new BL Touch and a SKR V1.4 Turbo (TMC2209s with sensorless homing on the X only) with Marlin 020004 on a Hypercupe Evo Core XY Build. So search and enable Z_SAFE_HOMING if using a BlTouch or probe. Triggering Z_STOP_PIN interrupts homing and leveling completely - failsafe when probe is failing, Triggering Z_STOP_PIN is combinded with probe signal - "first come, first served". I would sincerely appreciate any help. That shouldn't be a reason for this to just become forgotten. #define HOMING_FEEDRATE_Z (8*60) #define EEPROM_SETTINGS. I have run out of ideas. Marlin source code ; My main task is to convert my 3D printer into a chocolate printer. Option 7 only works when you enforce "HOMING_Z_WITH_PROBE" by commenting out the check of "!HAS_CUSTOM_PROBE_PIN" in 'inc/Conditionals_LCD.h'. #define Z_SAFE_HOMING. @bojanpotocnik please split this up in a bug and then a feature request so the 2 things are not mixed, will temp close this one until its split up in a bug and one feature request. Not feasible here. Then it moves to home X, and it tries to move the Z-axis up to Z_HOMING_HEIGHT, which is set from Z_CLEARANCE_BETWEEN_PROBES if that is defined (which it was for me, and it was 5). 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. All 4 files are also in the attached Base config (Z-endstop only, no BLTouch, homing at X=0, Y=0).zip file, the configuration in them matches the config in Option 1. Else you could not print at low altitudes (with probes like inductive, capacitiv, ...), yep, but in the mean time you could probably add some more documentation , probably near the Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN field clarifying the use of the dedicated probe connector, Option 1 : Good Have a question about this project? Marlin provides reasonable defaults, but they will not apply to every situation. HOMING_BUMP_DIVISOR, defined in Configuration_adv.h, is used to set the slowdown factor for the slow stage of homing. Hi, I decided to upgrade my firmware to marlin 1.1.8 but when I try to home Y, I do not get what is expected. I changed it from {10,10,20} to {2,2,2} and almost back to normal. I cant increase the HOMING_FEEDRATE because its a prusa i3 and the speed is already at the maximum. Defining a dedicated probe-pin implied there is a z-min-endstop and to use that for homing. I have Ender 3 with SKR Mini E3 v1.2 board, which has separate connectors for Z-endstop switch and BLTouch probe. Option 6 : expected, probe is only used for mesh generation in that config This is a guide to using g-code command M206 to set the Z axis home offset in the Marlin Firmware, a guide to a method of adjusting the gap distance between the hot end nozzle and the build platform. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. EDIT - don't forget to save and upload Marlin to your board when finished. I am techy but no coder so you have to bear with my results only comments\response. BLTouch is not used if using separate pin (that is if Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN is disabled)", because of the HOMING_Z_WITH_PROBE logic in Conditionals_LCD.h,or a feature request, Cofiguration option to use Z-endstop switch and BLTouch probe simultaneously. with Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN or commenting #define Z_STOP_PIN) and BLTouch probe just used in conjunction if the BLTOUCH is defined? Thanks ! I was think the exact same thing. Best Boothy. I tried an enormous amount of settings on/off, trying to use as little changes as possible to firmware, but growing in changes because I had simply tried every possible combination. All the speed and other settings for my printer all works like it should. I have replaced the filament extruder with a chocolate extruder. You haven't specified what version of Marlin you're running, so this applies to the git development tree. Look for a subsection of Z Probe Options called "section homing". Cookies help us deliver our Services. My case would most certainly on it's own be a BUG if using BLT homing does not work until using HOMING_Z_WITH_PROBE from a very unknown file such as Conditionals_LCD.h. Effectively printer is unstoppable when homing Z and will smash to the bed. @bojanpotocnik did excellent work in documenting and analyzing this problem. Already on GitHub? Hi, I changed my firmware settings in conditionals_lcd.h as per the attached screen grab from the default and the 5 test prints I have undertaken since have worked well with the BLTouch with no problems. Just to be clear, when you guys say option 7 works, the end switch is still not being monitoring during homing, correct? ... because of the HOMING_Z_WITH_PROBE logic in Conditionals_LCD.h,or a feature request. @boelle there are two bugs here, I can't see an FR. For the whole day I am trying to configure Marlin bugfix-2.0.x to achieve seemingly very simple things: That's it. Best Boothy. //#define MANUAL_X_HOME_POS 0 //#define MANUAL_Y_HOME_POS 0 //#define MANUAL_Z_HOME_POS 0 // Distance between the nozzle to printbed after homing. When the z axis homes , it touches the endstop and moves up and homes again , but when moving down to home the second time , it moves extremely slowly , it takes 1 minute to hit the endstop again. Most of us just simply replaced the z-min-endstop with a probe. Marlin 2.0.7 compiled to use BLTouch for z-axis (in the plate centre point) homing and ABL. When this was invented about no board had dedicated pins for a probe. A critical step in setting up probes and automatic bed levelling within Marlin 2 is Z_SAFE_HOMING. It seems the Marlin firmware is now assuming everyone uses a Z axis that does not sit at max travel during a power-off. period, the real issue is that marlin does not allow the usage of a custom pin as a BL-TOUCH probe connector as the new SKR boards are made for. Can option 7 be accomplished by connecting the probe of the bltouch and the z endstop in parallel? Expected behavior: Z homing is stopped as soon as (BLTouch or) Z-endstop switch is triggered. Default configuration, using only Z-endstop switch as Z-endstop. ❌ overall despite all ✔️, because we lost the Z-endstop switch. Reading this again I do not understand the HOMING_Z_WITH_PROBE logic - shouldn't the normal operation of the Z-endstop switch be retained (unless configured otherwise, e.g. When the z axis homes , it touches the endstop and moves up and homes again , but when moving down to home the second time , it moves extremely slowly , it takes 1 minute to hit the endstop again. When you say not being monitored do you mean the Z end switch is disabled ? if Z_MIN_PROBE_PIN is configured with additional probe functionality, then there are the two following use cases for the Z_STOP_PIN. We’ll occasionally send you account related emails. You could do what I did and go through the source code and delete all the stuff moving Z before XY homing. Option 5 : Forcing calculated value led to unintended but expected results. to your account. A probe can be used as a z-min-home-switch, not as a z-min-security-endstop. Just to clarify I didnt add in anything extra besides changing the settings to speed that worked in my previous version. In "failsafe" mode the trigger of Z_STOP_PIN should be mounted 0.5-1.0 mm under the trigger point of the probe. Add 2 // in front of the MIN_SOFTWARE_ENDSTOP_Z line in your Configuration.h file as shown below. ie one bug and one fr ? I've an skr mini v1.1 so same mcu. I know this is the same title as #12726, however I rather started a new issue for clarity as I made quite a few tests. Below is the description of all combinations of configurations, tested on the Ender 3 using SKR Mini E3 v1.2 with Z-endstop switch connected to the Z-STOP connector (PC2) and BLTouch connected to the SERVOS and PROBE connector (PC14). Disabling Z endpoint would just result in the bed crashing/grinding against my nozzle after my BLT measured and indicated a STOP signal in time, until reset/power off. I notice this at x and y axis but they definitely are not as slow as the z axis. If BLTouch is present and enabled, use it for homing. On a good setup, this isn't really required, but when getting to that point, it seems crashing into the bed isn't as uncommon as it should be, and a probe can fail even after working for some time. The other bug (I suggest reopening and renaming this issue) would be "[BUG] Z endstop is ignored when homing with separate Z probe despite defining ENDSTOPS_ALWAYS_ON_DEFAULT", A probe is not an endstop. Maybe the solution would be: The text was updated successfully, but these errors were encountered: Well, it is a bug and a question/feature request - maybe I'm just missing something. 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. It was trying to use an endstop on the same pin because of the flag. So using Z_SAFE_HOMING and setting X/Y location for Z homing seems appropriate. the expected behavior when you connect a bl-touch to anything else other then z-min is that triggering the bl-touch should stop the printer as though it was connected to z-min. #define Z_HOME_BUMP_MM 2. So it prevents the head from crashing into the bed and breaking thinner glasses or making some nice holes into the surface. Homing is required before G29, M48, and some other procedures.. You signed in with another tab or window. You will need to make sure software endstops are DISABLED for Z after adding the probe. PS: probably irrelevant, but I use 4x TMC2209 with DIAG pin cut off on XYZ. /r/3DPrinting is a place where makers of all skill levels and walks of life can learn about and discuss 3D printing. An endstop is not a probe" The original z-min-pin is not monitored during homing or printing with this configuration! Successfully merging a pull request may close this issue. +1 for this logical behaviour. I recently upgraded my prusa i3 firmware to a newer version of marlin. The Z will move a little and then stop, the X will home and then the Y carriage will bump in the endstop but the Y-motor keeps spinning, then the carriage will re-bump again against the endstop and the Y-motor will stop. I use bulldog clips to secure a glass bed. By using our Services or clicking I agree, you agree to our use of cookies. It is also hard to decide if this is a [BUG] or [FR] for Marlin, however it is certainly [BUG] for me. Is there another setting for this that I am unaware of ? I activate the Z_SAFE_HOMING option. This deals with not being able to Z home with a probe when using a dedicated probe pin. i would have opened another bug on it, but as you can see, someone already did, and with growing popularity of SKR board you'll probably have more bugs like this. Because, the new extruder is stopping slightly off the y-axis when homing. Simply mounting the endstop on the printer / keeping the end stop triggered in my hand for a few seconds after homing solved the issue for me. Is there no way to get attention from someone with enough expertise who can make this nessecary distinction? everything else is not relevant, z-min should be not effected by this, and triggering it should stop the printer as it did in the past, and if it doesn't , then it's another bug. It is going out of the standard 20x20 cm bed. Note that I tried tens of firmware settings except editing Conditionals_LCD.h. It is the total number of axis (3) plus the number of extruders (1). My Z axis the only axis that has a stallguard capable stepper driver, so I need to find a way to disable sensorless homing on X and Y. I am trying to get sensorless probing to work, so I can't cut the DIAG1 pin and just use a mechanical endstop. I fully agree with: "A probe is not an endstop. To ensure the nozzle stays clear of the clips, I’ve changed the following: Y_BED_SIZE from 235 to 199, X_MIN_POS from 0 to -2, Y_MIN_POS from 0 to -24. Description. In my case changing these settings made the Z end stop work in conjunction with the probe when homing .Before these changes it did not work at all even though I had the //#define Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN disabled\uncommented in configuration.h due to the SKR V1.4 board having a specific set of BLTouch connectors. Use M206 to apply a persistent offset to the native home position and coordinate space. Printer homes X and Y, then Z at the same spot (X = 0, Y = 0). An endstop is not a probe. I want to point out that using BLT in conjunction with a Z endstop switch is so simple in essence and important, a more complex & fragile Z-probe protecting important parts like nozzle, bed, belts should have a fail-safe. I have the same issue with my both brand new SKR1.4 & BL-Touch, installed on my Creality Ender 4. This will let you adjust the Z to a negative number for your offset. ENDSTOPS_ALWAYS_ON_DEFAULT reacts on endstops, not probes by purpose. This is where you define home direction. For setting the speed of a specific axes in firmware you should change the next settings in Marlin: #define HOMING_FEEDRATE_Z (8*60) If you don't like 8, set with another value. Until I found this issue! By clicking “Sign up for GitHub”, you agree to our terms of service and The simplest way was to use a unused endstop-pin. One I already raised, #16839. Z_SAFE_HOMING. I have Ender 3 with SKR Mini E3 v1.2 board, which has separate connectors for Z-endstop switch and BLTouch probe. #define X_HOME_BUMP_MM 5. #16839 encompasses that item. Press question mark to learn the rest of the keyboard shortcuts. From this point onwards, the following is also uncommented: In every of the following options, after homing X and Y, printer goes to the center of the bed and performs Z-homing (Z_SAFE_HOMING) ✔️. Once I clicked an endstop I should have kept it closed since the homing expects to keep the switch in a triggered state once it does the step back to the homing position. And now for the feature request / question part: Should it be by default or at least possible for the the user to use Z-endstop switch and BLTouch probe simultaneously without editing the Conditionals_LCD.h file as described in the Option 7 above? I'm surprised this hasn't been figured out and intergrated as it seems like basic functionality. Assuming they are sending the same signal, to the board, the end switch would represent a lower bound for the probe. My BLT was functioning correctly: controllable with G-Code commands, M119 gave triggered & open responses when deploying BLT probing pin and pushing it up by hand. Apologies again for my lack of experience. In the code you can see, that the author disabled homing with a probe explicitly if a custom probe pin was configured. it's a bug. Since I’m homing to Z-max when G28 is executed by marlin it will home Z first (moving to the endstop, and setting Z to Z_MAX_POS (0 in my case). Actual behavior: Z-endstop switch is ignored, Z homing stops only when the BLTouch probe is triggered. A probe needs to be deployed, or at least switched on. As a side-effect, X and Y homing are required before Z homing. I use pronterface to do all my testing. I'm new to bltouch and found this thread while planning to put in my probe. It then behaves like classic homing with manually leveled bed (traditional way). See examples below. Also many capacitive or IR probes will view the part you are printing as a trigger. Please open a new issue for related bugs. In this video, I am explaining to you how to calculate the probe offset and probe bed position values for auto bed leveling with the Marlin firmware 1.1.X. ENDSTOPS_ALWAYS_ON_DEFAULT reacts on endstops, not probes by purpose. I hope others with similar issues can find a solution here. Having now told you my inexperience, please allow me to ask a potentially stupid question. A probe needs to be deployed, or at least switched on. It is common for X and Y axis to home the hot end to the Zero location and Z axis end stop home to the maximum positive location. #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. It would be a dirty hack though. #define Y_HOME_BUMP_MM 5. This problem was exacerbated for my mahine having longer ribbon cables than stock. Base config (Z-endstop only, no BLTouch, homing at X=0, Y=0).zip, fork marlin in separate git repo for easier comparison, [BUG] Z-endstop switch ignored while homing when using BLTouch, [BUG] Z homing using a Z probe should be allowed when using a custom probe pin. From a clean fir #define Z_MIN_POS 0. 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 … Wich part is a BUG or FEATURE REQUEST is just simply a matter of perspective and even argumenting this binary descision get's endlessly complex, stopping @bojanpotocnik, me or someone else to continue this issue. ? Homing feed rate. 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). This ^ and make sure your steps / mm are correct. I've been trying to fix an issue with my Y homing function for quite some time. Or is there any other combination of configurations (or Option in my initial post) to achieve this functionality? An endstop is not a probe. It is also hard to decide if this is a [BUG] or [FR] for Marlin, however it is certainly [BUG] for me. Follow with M420 S to turn leveling on, or use RESTORE_LEVELING_AFTER_G28 to automatically keep leveling on after G28. Help needed : Marlin z axis homing speed settings. This effectively shifts the coordinate space in the negative direction. [BUG] Z homing with BLTouch and Z-endstop switch. #define NUM_AXIS 4. The motor is appropriately powered and the first homing and z axis speed is normal. With the settings in option #7 from @bojanpotocnik it all suddenly worked. All 4 files are also in the attached Base config (Z-endstop only, no BLTouch, homing at X=0, Y=0).zip file, the configuration in them matches the config in Option 1. Prior to changing these settings I was getting repeat lack of homing on Z and home failures with a request to reset. The other X and Z axes are OK. @ruggb your X/Y min could be outside of the bed and defaulting to (0,0) might be not relevant if you haven't set X/Y_MIN_POS properly, and Marlin can't guess that. 2.0.5. The current position is adjusted to align to the new home offset values. Sign in Speaker is also disabled as the beeps annoy me :D A probe is not an endstop. Basically you tell the Marlin firmware which end of the axis the end stop switch is located. So for example with the default value: Delta configurations use a much higher divisor, maybe you've accidentally used the wrong configuration. Notes. The "combined" mode is more a "soft failsafe", if probe has failed or is missing (for unknown reason). Right now I'm in option 2 and looking for a solution in order to get option 7 working. Now - since more boards do have a dedicated probe-pin we could rethink that. Bugfix, later 2.0.6. As soon as I used the option 7 suggestion in Conditionals_LCD.h as per Releece`s comments above everything worked perfectly straight away. Uncomment Z_SAFE_HOMING. I recently upgraded my prusa i3 firmware to a newer version of marlin. Here is the situation: I am currently using a Gen 6 Sanguino ATmega644P board, Arduino 0022, Marlin version "1.0.0 Beta 1".
