marlin disable z homing

#else thinkyhead When I get time, I'll mess around some more and try to add some lines so that the end-stop can be used as a fail-safe in case of probe failure (which is probably the original code's intent). :), i tried to print one of my old files, and it seems like the plate site is written wrong it prints it very very very small, but i got it on 308mm in marlin and the plate is 310. Tried all the newest marlin changes shown in this issue. Now, that last line... Z_HOME_DIR < 0 is fine, this ensures you're probing downwards for your Z axis, which we are, and by default this is set to -1. I've been asking around, but no one seems to have found a solution. Got an official BLTouch after that and it worked fine. Meaning that the z-height offset has to be something like 6mm, and I have no idea if it will even do a bed mesh at that point. #define Z_STOP_PIN P0_10 // Z-STOP. If you insist on removing the z-endstop switch you'll likely either need to swap the BLTouch z-pins to the normal z-endstop, or use SENSORLESS_PROBING and rely on stallguard for the z-axis. This offset is used to determine the actual Z position of the nozzle when using a probe to home Z with G28. Now do another G28 (auto-home) command. | Many commercial 3D printers come with Marlin installed. )++++++ released this Driver: TMC2209 clipped pin for the Z-axis (I wanted to use the physical Z-axis endstop) Any news on this? I had to buy a different 3d printer control board with a plug for the bltouch. thus the conflict with oneself is eliminated! #define HAS_PROBE_XY_OFFSET 1 The text was updated successfully, but these errors were encountered: I'm having the same issue with SKR v1.4 Turbo + BLTOUCH v3.1. in Configuration.H please change these points as shown! I've just been setting up my Ender 3 Pro with an BTT SKR 1.4 Turbo fitted with TMC2209's. To: bigtreetech/BIGTREETECH-SKR-V1.3 BIGTREETECH-SKR-V1.3@noreply.github.com I assume you use an end stop device for X, Y and Z and the BLTouch in addition to them. Marlin firmware (version 1.1.0 and later) provides an option called Z_SAFE_HOMING for printers that use a Z probe to home Z instead of an endstop. Just keep an #define HOMING_Z_WITH_PROBE (Z_HOME_DIR < 0)// && !HAS_CUSTOM_PROBE_PIN) #define HAS_CUSTOM_PROBE_PIN true Using SKR 1.4 Turbo. BLTOUCH wires are connected to SERVOS header and Probe header as indicated in the wiring diagram documentation: I tried just commenting out this line: #if DISABLED(NOZZLE_AS_PROBE) #define HOMING_Z_WITH_PROBE (Z_HOME_DIR < 0) That is very interesting. When auto home i get error. #define HAS_CUSTOM_PROBE_PIN DISABLED(Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN) Homing of multiple axes in parallel. IDK if this helps but I pulled an all-nighter getting my SKR V1.4 (non-turbo) all configured for my printer and first time installing BLTouch. I tried with both force 5v on and off and it worked both ways for me, honestly. when an end-stop is connected. Ordered a new bltouch and the error still exists. From: Chazy12 @Culem94https://github.com/Culem94 Check you wiring is correct. I had to register on GitHub to make my 1st comment, so please be patient my wordiness. #define USE_PROBE_FOR_Z_HOMING // CHANGE THIS - Enable, //#define Z_MIN_PROBE_PIN 32 // Leave-as or revert to Marlin default probe doesn't home properly. Mein Einstellungen bei Marlin 2.0.6 habe auch einige Zeit benötigt und etwas Experimentiert mit den Einstellungen um eine Lösung zu finden. Follow all of the steps and settings in Appendix K and everything will be spot on to get it running and ready for some tuning. // - Allow Z homing only after X and Y homing AND stepper drivers still enabled // - If stepper drivers timeout, it will need X and Y homing again before Z homing // - Position the probe in a defined XY point before Z Homing when homing all axis (G28) // - Block Z homing only when the probe is outside bed area. Update French, German, Spanish, Portuguese, Czech languages. One thing you can try is to use Cheetah 5.0, which is a build of Marlin 2.0.3 and change the pin file. My pin still doesn't deploy for whatever reason during Z homing, even though it works fine with deploy/stow and self-test. //#define Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN Cc: rlbeers ; Comment Sign in My settings for Marlin 2.0.6 also took some time and I experimented with the settings to find a solution. Thanks for this work. Wiring is checked and is correct as-per PDF (i've always had it correct, from the looks of things). homing Z by using the Z-endstop pins for it instead of the designated probe making a few changes. I just know that I have sensorless homing, stallguard, BLTouch 3.1 (authentic) connected to the dedicated pins, cooling fan on auto as well as hotend fan. ), @thelittlemike PS - Love the custom machine name ;), Comment out the line in Configuration.H: I've just run into this myself and you've saved me a lot of pain. The probe can do self-test etc, but when I try to home the Z axis, the BLTOUCH probe does not deploy. Homing cartesian axes involved in a coordinate transformation (e.g. Initially I had some issue with the z-homing but after experimenting I've been able to get it working well using the SKR1.4's dedicated z-probe pins. 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. in Configuration_adv.h habe ich diese Einstellungen. FINAL attempt to configure BLTouch: SUCCESS (everything is the same as above, except for below) Oct 30, 2020, thinkyhead Successfully merging a pull request may close this issue. and try to add some lines so that the end-stop can be used as a fail-safe Here's my configs if maybe some of you guys can reverse engineer what I did. row 636 #if Z_HOME_DIR < 0 && (!HAS_CUSTOM_PROBE_PIN || ENABLED(USE_PROBE_FOR_Z_HOMING)). Good work @hopeinformer ! So search and enable Z_SAFE_HOMING if using a BlTouch or probe. @S13Tyler - The change you suggested in the Conditionals_LCD.h file works great until version 2.0.4.4. of Marlin. With so many new files being added, a lot of work has gone into optimizing the PlatformIO build by peeking at enabled features and only downloading libraries and compiling code required for your enabled options. RESULTS: The BLTouch was functional, and no Z homing crash. So for most users, this returns true and we can ignore it here. I'm too lazy to open up the case and check what the wiring is like, but I suppose I could be convinced to do so if needed. Anyways, after several print jobs and reboots, the BLTouch and SKR 1.4 Turbo are now working together as intended. ^^ Much has changed and I am rather confused: I have regular X, Y and Z endstop switches installed, BL touch (clone) probe plugged into servo + probe ports and being on the latest Marlin main branch (so 2.0.6 + some commits): What are the steps now to enable the BLTouch in Marlin "the correct way" (so as little hacky as possible)? It worked as it should for a few times then went right back to Slave steppers, driven synchronously, can be configured for an axis (e.g. This is when using the designated BLTOUCH probe pins, i.e. But I don't think all of them have to be absolutely necessary, but you should test it out yourself! the latest BTT firmware for the 1.4 Turbo is based on an older version of Marlin so this still works.

Aug 28, 2020, thinkyhead #ifndef Z_PROBE_LOW_POINT In essence, the Marlin developers have said, "If you have a custom probe pin, you cannot home with your Z probe." // Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN When the BLTOUCH is sitting idle, an M119 command shows that Z_Probe and z_min are in state 'TRIGGERED' , when they should not be, according to Marlin firmware documentation: The BLTOUCH probe only sends a brief pulse, so “TRIGGERED” indicates the probe is in error state. released this this is a rather dangerous band-aid, if you just disable Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN the probe will come crushing down the bed, so this fix could be forgotten during upgrades between firmwares! I also have the original z-endstop microswitch still wired up and this is critical to it working. I didn't change the firmware at all between it Unfortunately in the new Marlin release 2.0.5 the Conditionals_LCD.h file is very different. [image: image] View Commits, thinkyhead * Note the Z axis value on the display it should be something like -1.5 M851 Z-1.5 ; to set the offset you got in the previous step. #define HOMING_Z_WITH_PROBE (Z_HOME_DIR < 0 &&!HAS_CUSTOM_PROBE_PIN) By clicking “Sign up for GitHub”, you agree to our terms of service and pins. and define: #define HAS_CUSTOM_PROBE_PIN true Simplify3D allows you to customize the ending script that is run at the very end of each print.

If you wish to move the nozzle away from the part, simply add a command such as “G28 X0” to the beginning of this script to move the X-axis towards the homing endstop switch and away from the finished part. I am new to 3D printing and Marlin but have been able to get the BLTouch working on my SKR Pro v1.1, so maybe i can help a bit. Running Ender 3 Pro + SKR 1.4 Turbo + BL Touch 3.1 + TFT35-3.0 v3.0.
