Look for a subsection of Z Probe Options called "section homing". Not feasible here. 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. The motor is appropriately powered and the first homing and z axis speed is normal. This issue has been automatically locked since there has not been any recent activity after it was closed. Follow with M420 S to turn leveling on, or use RESTORE_LEVELING_AFTER_G28 to automatically keep leveling on after G28. 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. Marlin source code ; My main task is to convert my 3D printer into a chocolate printer. I have the same issue with my both brand new SKR1.4 & BL-Touch, installed on my Creality Ender 4. So using Z_SAFE_HOMING and setting X/Y location for Z homing seems appropriate. In "failsafe" mode the trigger of Z_STOP_PIN should be mounted 0.5-1.0 mm under the trigger point of the 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". In general, on deltabots the probe should be connected to the unused Z-Min endstop pin (if there is one). 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) ✔️. Actual behavior: Z-endstop switch is ignored, Z homing stops only when the BLTouch probe is triggered. This deals with not being able to Z home with a probe when using a dedicated probe pin. ? A probe needs to be deployed, or at least switched on. I am techy but no coder so you have to bear with my results only comments\response. 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. that solved my problem . 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. I have run out of ideas. You signed in with another tab or window. Press question mark to learn the rest of the keyboard shortcuts. I use bulldog clips to secure a glass bed. I activate the Z_SAFE_HOMING option. This problem was exacerbated for my mahine having longer ribbon cables than stock. Basically you tell the Marlin firmware which end of the axis the end stop switch is located. //#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. 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). Effectively printer is unstoppable when homing Z and will smash to the bed. The other X and Z axes are OK. /r/3DPrinting is a place where makers of all skill levels and walks of life can learn about and discuss 3D printing. ENDSTOPS_ALWAYS_ON_DEFAULT reacts on endstops, not probes by purpose. If stepper drivers time out, X and Y homing will be required again. By clicking “Sign up for GitHub”, you agree to our terms of service and 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. Notes. +1 for this logical behaviour. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. A probe is not an endstop. 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. 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. I would sincerely appreciate any help. This is the moving speed of the axis when homing in [mm/min]. Option 3 : Expected as the bltouch normally only triggers as a pulse and otherwise a constant trigger is considered a fault. In every step/combination, all other relevant configuration defines are shown for clarity. By using our Services or clicking I agree, you agree to our use of cookies. 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). The Z axis already had the wires separated. 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. This ^ and make sure your steps / mm are correct. 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. The "combined" mode is more a "soft failsafe", if probe has failed or is missing (for unknown reason). Also many capacitive or IR probes will view the part you are printing as a trigger. I fully agree with: "A probe is not an endstop. This is where you define home direction. 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. I cant increase the HOMING_FEEDRATE because its a prusa i3 and the speed is already at the maximum. I'm surprised this hasn't been figured out and intergrated as it seems like basic functionality. Bugfix, later 2.0.6. You could do what I did and go through the source code and delete all the stuff moving Z before XY homing. Please open a new issue for related bugs. An endstop is not a probe. Option 7 : Same configuration option needed from Option 2. Thanks ! 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. Without this option enabled the nozzle will crash into the bed when homing. Is there another setting for this that I am unaware of ? it's a bug. 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. That shouldn't be a reason for this to just become forgotten. Z_SAFE_HOMING. ie one bug and one fr ? @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. Can option 7 be accomplished by connecting the probe of the bltouch and the z endstop in parallel? 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? Having now told you my inexperience, please allow me to ask a potentially stupid question. I noticed this too on my K8200. 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 … 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. 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 #define Z_MIN_POS 0. You haven't specified what version of Marlin you're running, so this applies to the git development tree. privacy statement. 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. 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. Thanks to #7470, #define ENDSTOPS_ALWAYS_ON_DEFAULT is always uncommented (enabled). 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. Marlin 2.0.7 compiled to use BLTouch for z-axis (in the plate centre point) homing and ABL. Else you could not print at low altitudes (with probes like inductive, capacitiv, ...). Add 2 // in front of the MIN_SOFTWARE_ENDSTOP_Z line in your Configuration.h file as shown below. Prior to changing these settings I was getting repeat lack of homing on Z and home failures with a request to reset. Note that I tried tens of firmware settings except editing Conditionals_LCD.h. Thanks to #7470, #define ENDSTOPS_ALWAYS_ON_DEFAULT is always uncommented (enabled). Defining a dedicated probe-pin implied there is a z-min-endstop and to use that for homing. It is going out of the standard 20x20 cm bed. ENDSTOPS_ALWAYS_ON_DEFAULT reacts on endstops, not probes by purpose. 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. 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. if Z_MIN_PROBE_PIN is configured with additional probe functionality, then there are the two following use cases for the Z_STOP_PIN. I recently upgraded my prusa i3 firmware to a newer version of marlin. 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. You will need to make sure software endstops are DISABLED for Z after adding the probe. It seems the Marlin firmware is now assuming everyone uses a Z axis that does not sit at max travel during a power-off. #define Z_SAFE_HOMING. 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. #16839 encompasses that item. Now - since more boards do have a dedicated probe-pin we could rethink that. I have Ender 3 with SKR Mini E3 v1.2 board, which has separate connectors for Z-endstop switch and BLTouch probe. The simplest way was to use a unused endstop-pin. 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. I expect the new stronger motor TMC2209 driver signals increase the coupling noise, or maybe the skr switch sensors are more sensitive to noise. 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. Is there no way to get attention from someone with enough expertise who can make this nessecary distinction? 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 have replaced the filament extruder with a chocolate extruder. For the whole day I am trying to configure Marlin bugfix-2.0.x to achieve seemingly very simple things: That's it. Option 5 : Forcing calculated value led to unintended but expected results. Speaker is also disabled as the beeps annoy me :D In the code you can see, that the author disabled homing with a probe explicitly if a custom probe pin was configured. As soon as I used the option 7 suggestion in Conditionals_LCD.h as per Releece`s comments above everything worked perfectly straight away. Sign in If homing is needed the LCD will blink the X Y Z indicators. 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. A probe needs to be deployed, or at least switched on. 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. #define HOMING_FEEDRATE_Z (8*60) #define EEPROM_SETTINGS. It is also hard to decide if this is a [BUG] or [FR] for Marlin, however it is certainly [BUG] for me. @bojanpotocnik did excellent work in documenting and analyzing this problem. So it prevents the head from crashing into the bed and breaking thinner glasses or making some nice holes into the surface. @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. 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. As a side-effect, X and Y homing are required before Z homing. Already on GitHub? Just to be clear, when you guys say option 7 works, the end switch is still not being monitoring during homing, correct? When you say not being monitored do you mean the Z end switch is disabled ? If your bed is non-standard, you’ll need to adjust the size and/or travel limits to make sure Marlin knows this. @InsanityAutomation I think there's an additional piece here - when both Z Probe and Z endstop are connected, provide an option to listen to both probe and endstop for homing, stopping when either one of them triggers. On machines that use Z-min for an endstop, the Z-Max pin is recommended next, so this is … Or is there any other combination of configurations (or Option in my initial post) to achieve this functionality? Option 6 : expected, probe is only used for mesh generation in that config Best Boothy. So for example with the default value: Delta configurations use a much higher divisor, maybe you've accidentally used the wrong configuration. #define X_HOME_BUMP_MM 5. See examples below. It would be a dirty hack though. 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. Expected behavior: Z homing is stopped as soon as (BLTouch or) Z-endstop switch is triggered. An endstop is not a probe. I recently upgraded my prusa i3 firmware to a newer version of marlin. So search and enable Z_SAFE_HOMING if using a BlTouch or probe. Cookies help us deliver our Services. I notice this at x and y axis but they definitely are not as slow as the z axis. Because, the new extruder is stopping slightly off the y-axis when homing. This effectively shifts the coordinate space in the negative direction. 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). Description. This means the system needs first to establish its starting point of the physical (machine) coordinate system, a process called Homing. We’ll occasionally send you account related emails. I'm new to bltouch and found this thread while planning to put in my probe. #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. Homing feed rate. EDIT - don't forget to save and upload Marlin to your board when finished. PROBE_USES_Z_MIN_ENDSTOP implied there is no z-min-endstop - use the probe for homing z to min. This will let you adjust the Z to a negative number for your offset. ❌ overall despite all ✔️, because we lost the Z-endstop switch. #define Z_HOME_BUMP_MM 2. #define Y_HOME_BUMP_MM 5. 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. 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. 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? This has been the key to fix my issue, except it is not straightforward or well documented at all. PS: probably irrelevant, but I use 4x TMC2209 with DIAG pin cut off on XYZ. 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). Printer homes X and Y, then Z at the same spot (X = 0, Y = 0). It is also hard to decide if this is a [BUG] or [FR] for Marlin, however it is certainly [BUG] for me. A probe can be used as a z-min-home-switch, not as a z-min-security-endstop. However when homing Z the BLT probe signal was ignored every time & only the Z endpoint switch would conclude the homing. Have a question about this project? It was trying to use an endstop on the same pin because of the flag. HOMING_BUMP_DIVISOR, defined in Configuration_adv.h, is used to set the slowdown factor for the slow stage of homing. I've been trying to fix an issue with my Y homing function for quite some time. All the speed and other settings for my printer all works like it should. @boelle there are two bugs here, I can't see an FR. I hope others with similar issues can find a solution here. 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. If BLTouch is present and enabled, use it for homing. Discussion. Press J to jump to the feed. 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). I have Ender 3 with SKR Mini E3 v1.2 board, which has separate connectors for Z-endstop switch and BLTouch probe. Until I found this issue! 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. From a clean fir As far as I can see there is only 1 actionable item here. I have tried changing MAX_FEEDRATE , MAX_ACCELERATION , HOMING_FEEDRATE . When this was invented about no board had dedicated pins for a probe. Right now I'm in option 2 and looking for a solution in order to get option 7 working. 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. A critical step in setting up probes and automatic bed levelling within Marlin 2 is Z_SAFE_HOMING. It then behaves like classic homing with manually leveled bed (traditional way). Option 4 : most common setup and really identical functionally to 3 Use M206 to apply a persistent offset to the native home position and coordinate space. 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. Default configuration, using only Z-endstop switch as Z-endstop. I changed it from {10,10,20} to {2,2,2} and almost back to normal. Most of us just simply replaced the z-min-endstop with a probe. to your account. 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. Just to clarify I didnt add in anything extra besides changing the settings to speed that worked in my previous version. Apologies again for my lack of experience. 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. The current position is adjusted to align to the new home offset values. This was accidentally tested as I forgot to comment #define Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN. Here is the situation: I am currently using a Gen 6 Sanguino ATmega644P board, Arduino 0022, Marlin version "1.0.0 Beta 1". G28 disables bed leveling. // For DELTA this is the top-center of the Cartesian print volume. Help needed : Marlin z axis homing speed settings. [BUG] Z homing with BLTouch and Z-endstop switch. In every step/combination, all other relevant configuration defines are shown for clarity. Im using RAMPS 1.4 on my Hypercube with Marlin 1.1.5. #define Z_SAFE_HOMING. With the settings in option #7 from @bojanpotocnik it all suddenly worked. Marlin provides reasonable defaults, but they will not apply to every situation. Best Boothy. Movement settings Define the number of axis. 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. Assuming they are sending the same signal, to the board, the end switch would represent a lower bound for the probe. The original z-min-pin is not monitored during homing or printing with this configuration! An endstop is not a probe" 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. 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 I was think the exact same thing. Uncomment Z_SAFE_HOMING. 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'. ... because of the HOMING_Z_WITH_PROBE logic in Conditionals_LCD.h,or a feature request. 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. Making this fully functional and easily selectable is a wise idea. One I already raised, #16839. I use pronterface to do all my testing. 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. I've an skr mini v1.1 so same mcu.
