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. Expected behavior: Z homing is stopped as soon as (BLTouch or) Z-endstop switch is triggered. Because, the new extruder is stopping slightly off the y-axis when homing. On machines that use Z-min for an endstop, the Z-Max pin is recommended next, so this is … When this was invented about no board had dedicated pins for a probe. It was trying to use an endstop on the same pin because of the flag. #define Z_SAFE_HOMING. Speaker is also disabled as the beeps annoy me :D Sign up for a free GitHub account to open an issue and contact its maintainers and the community. Prior to changing these settings I was getting repeat lack of homing on Z and home failures with a request to reset. HOMING_BUMP_DIVISOR, defined in Configuration_adv.h, is used to set the slowdown factor for the slow stage of 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. ie one bug and one fr ? This issue has been automatically locked since there has not been any recent activity after it was closed. I use bulldog clips to secure a glass bed. As a side-effect, X and Y homing are required before Z homing. This is the moving speed of the axis when homing in [mm/min]. 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. Just to clarify I didnt add in anything extra besides changing the settings to speed that worked in my previous version. that solved my problem . 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. 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. 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. If stepper drivers time out, X and Y homing will be required again. Option 3 : Expected as the bltouch normally only triggers as a pulse and otherwise a constant trigger is considered a fault. 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). 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. Have a question about this project? 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. For the whole day I am trying to configure Marlin bugfix-2.0.x to achieve seemingly very simple things: That's it. I have Ender 3 with SKR Mini E3 v1.2 board, which has separate connectors for Z-endstop switch and BLTouch probe. 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. /r/3DPrinting is a place where makers of all skill levels and walks of life can learn about and discuss 3D printing. I expect the new stronger motor TMC2209 driver signals increase the coupling noise, or maybe the skr switch sensors are more sensitive to noise. You signed in with another tab or window. 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. This means the system needs first to establish its starting point of the physical (machine) coordinate system, a process called Homing. 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. 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. @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. //#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. I use pronterface to do all my testing. The Z axis already had the wires separated. It is the total number of axis (3) plus the number of extruders (1). #define Z_HOME_BUMP_MM 2. The simplest way was to use a unused endstop-pin. 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. 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 #define Y_HOME_BUMP_MM 5. 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. So for example with the default value: Delta configurations use a much higher divisor, maybe you've accidentally used the wrong configuration. 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). 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. 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 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. Right now I'm in option 2 and looking for a solution in order to get option 7 working. The current position is adjusted to align to the new home offset values. You haven't specified what version of Marlin you're running, so this applies to the git development tree. 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 effectively shifts the coordinate space in the negative direction. 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? Please open a new issue for related bugs. Follow with M420 S to turn leveling on, or use RESTORE_LEVELING_AFTER_G28 to automatically keep leveling on after G28. Sign in 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 … 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). A critical step in setting up probes and automatic bed levelling within Marlin 2 is Z_SAFE_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. If your bed is non-standard, you’ll need to adjust the size and/or travel limits to make sure Marlin knows this. 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". One I already raised, #16839. Having now told you my inexperience, please allow me to ask a potentially stupid question. 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. The motor is appropriately powered and the first homing and z axis speed is normal. I've an skr mini v1.1 so same mcu. Is there another setting for this that I am unaware of ? 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. Notes. A probe is not an endstop. If homing is needed the LCD will blink the X Y Z indicators. Most of us just simply replaced the z-min-endstop with a probe. 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. 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. // 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. Best Boothy. You could do what I did and go through the source code and delete all the stuff moving Z before XY homing. As soon as I used the option 7 suggestion in Conditionals_LCD.h as per Releece`s comments above everything worked perfectly straight away. I have replaced the filament extruder with a chocolate extruder. ? I recently upgraded my prusa i3 firmware to a newer version of marlin. Bugfix, later 2.0.6. 2.0.5. 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. @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. I have Ender 3 with SKR Mini E3 v1.2 board, which has separate connectors for Z-endstop switch and BLTouch probe. This will let you adjust the Z to a negative number for your offset. Movement settings Define the number of axis. if Z_MIN_PROBE_PIN is configured with additional probe functionality, then there are the two following use cases for the Z_STOP_PIN. It would be a dirty hack though. In general, on deltabots the probe should be connected to the unused Z-Min endstop pin (if there is one). In "failsafe" mode the trigger of Z_STOP_PIN should be mounted 0.5-1.0 mm under the trigger point of the probe. 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. As far as I can see there is only 1 actionable item here. I have the same issue with my both brand new SKR1.4 & BL-Touch, installed on my Creality Ender 4. Thanks to #7470, #define ENDSTOPS_ALWAYS_ON_DEFAULT is always uncommented (enabled). Marlin provides reasonable defaults, but they will not apply to every situation. I fully agree with: "A probe is not an endstop. Option 7 : Same configuration option needed from Option 2. It is also hard to decide if this is a [BUG] or [FR] for Marlin, however it is certainly [BUG] for me. We’ll occasionally send you account related emails. #16839 encompasses that item. 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? I am techy but no coder so you have to bear with my results only comments\response. PS: probably irrelevant, but I use 4x TMC2209 with DIAG pin cut off on XYZ. I'm surprised this hasn't been figured out and intergrated as it seems like basic functionality. [BUG] Z homing with BLTouch and Z-endstop switch. Without this option enabled the nozzle will crash into the bed when homing. With the settings in option #7 from @bojanpotocnik it all suddenly worked. it's a bug. #define Z_SAFE_HOMING. 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. +1 for this logical behaviour. Just to be clear, when you guys say option 7 works, the end switch is still not being monitoring during homing, correct? Is there no way to get attention from someone with enough expertise who can make this nessecary distinction? 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). Not feasible here. 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. If BLTouch is present and enabled, use it for homing. Apologies again for my lack of experience. I would sincerely appreciate any help. An endstop is not a probe" I noticed this too on my K8200. I activate the Z_SAFE_HOMING option. Description. 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. ENDSTOPS_ALWAYS_ON_DEFAULT reacts on endstops, not probes by purpose. Assuming they are sending the same signal, to the board, the end switch would represent a lower bound for the probe. Else you could not print at low altitudes (with probes like inductive, capacitiv, ...). I changed it from {10,10,20} to {2,2,2} and almost back to normal. It seems the Marlin firmware is now assuming everyone uses a Z axis that does not sit at max travel during a power-off. In every step/combination, all other relevant configuration defines are shown for clarity. Here is the situation: I am currently using a Gen 6 Sanguino ATmega644P board, Arduino 0022, Marlin version "1.0.0 Beta 1". Also many capacitive or IR probes will view the part you are printing as a trigger. This is where you define home direction. #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. 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 hope others with similar issues can find a solution here. A probe needs to be deployed, or at least switched on. Or is there any other combination of configurations (or Option in my initial post) to achieve this functionality? Can option 7 be accomplished by connecting the probe of the bltouch and the z endstop in parallel? 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. This ^ and make sure your steps / mm are correct. When you say not being monitored do you mean the Z end switch is disabled ? Already on GitHub? I have tried changing MAX_FEEDRATE , MAX_ACCELERATION , HOMING_FEEDRATE . Option 6 : expected, probe is only used for mesh generation in that config #define HOMING_FEEDRATE_Z (8*60) #define EEPROM_SETTINGS. Effectively printer is unstoppable when homing Z and will smash to the bed. privacy statement. I'm new to bltouch and found this thread while planning to put in my probe. I recently upgraded my prusa i3 firmware to a newer version of marlin. @bojanpotocnik did excellent work in documenting and analyzing this problem. From a clean fir Look for a subsection of Z Probe Options called "section homing". A probe can be used as a z-min-home-switch, not as a z-min-security-endstop. 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. 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. It is going out of the standard 20x20 cm bed. Until I found this issue! So search and enable Z_SAFE_HOMING if using a BlTouch or probe. This problem was exacerbated for my mahine having longer ribbon cables than stock. Thanks to #7470, #define ENDSTOPS_ALWAYS_ON_DEFAULT is always uncommented (enabled). An endstop is not a probe. 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. G28 disables bed leveling. And it is there that my issue began. Im using RAMPS 1.4 on my Hypercube with Marlin 1.1.5. Cookies help us deliver our Services. can we split it up 2? 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. Thanks ! So using Z_SAFE_HOMING and setting X/Y location for Z homing seems appropriate. #define Z_MIN_POS 0. 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. ENDSTOPS_ALWAYS_ON_DEFAULT reacts on endstops, not probes by purpose. You will need to make sure software endstops are DISABLED for Z after adding the probe. Marlin 2.0.7 compiled to use BLTouch for z-axis (in the plate centre point) homing and ABL. Note that I tried tens of firmware settings except editing Conditionals_LCD.h. I have run out of ideas. The original z-min-pin is not monitored during homing or printing with this configuration! It then behaves like classic homing with manually leveled bed (traditional way). Basically you tell the Marlin firmware which end of the axis the end stop switch is located. The "combined" mode is more a "soft failsafe", if probe has failed or is missing (for unknown reason). 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. Printer homes X and Y, then Z at the same spot (X = 0, Y = 0). Z_SAFE_HOMING. An endstop is not a probe. 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.
