planner.settings.max_acceleration_mm_per_s2[X_AXIS] = 500; >planner.settings.max_acceleration_mm_per_s2[Y_AXIS] = 500; I just tried dch1921's suggestion, it doesn't seem to change anything other than the values where the issue happens. Answer questions lovethat777. 0,0 is on left bottom of the Buildplate, as usual. I have tried setting up floats for the value but it won't accept them, and I also tried switching it with another TMC2209 with exactly the same result. So basically, @boelle was correct in saying this was a setup issue, but to my knowledge, the homing speed affecting the sensorless homing isn't documented anywhere. In my printer I use a leveling function available in Marlin 2 called BABYSTEPPING. Successfully merging a pull request may close this issue. Very easy as you have been able to check, click on those 2 sites and that’s it. My assumption was the lower acceleration was causing a false stallgaurd detect when the axis first starts to move and the faster speed allows it to overcome the initial load it sees when it is starting from a stationary position. Now we will save the Configuration.h file and edit a new file called Configuration_adv.h . If we make the leveling of the printing surface in the 4 corners, when you are leveling one another it is unbalanced. SKR v1.3, and BTT 2209s. Ironically, that's not the point of sensorless homing 😂. By default it is deactivated, so we will activate the BABYSTEPPING option, as I show you below: Well, these would be the basic options to configure your BLTouch. I also created a custom homing button in OctoPrint. Thingiverse is a universe of things. It is simply adding the G29 command to level your head before each impression. I have gone through the datasheet and haven't seen anything that'd point to that anyway. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. This is done very easily by configuring yourself in your favorite Slicer (Repetier, Simplify3D, Cura, etc.). Diag pin of TMC is well connected to Zmin signal, and Zmin work well when I put it to Vcc. But removing jumper onboard (XST or YST, which disconnects diag pin to endstop switch) will result in M119 saying "Triggered", Jumper engaged, and continuously says "open" 100% success rate since I've done that! @uorbe001 I have sensorless homing and probing working (after few weeks of testing) with BTT TMC 2209 v1.2 on a SKR Pro. Confirmed on my end. It would not be surprising if he had left me something in the pipeline, if so, do not hesitate to notify me in the comments at the end of the article Install and configure BLTouch / 3DTouch in Marlin 2.0.x (MKS Gen, SKR, Anet A8, RAMPS). The recommended is 2mm. I leave you an example of my startup script on each print: To finish, and having activated BabyStepping you will have your own menu called Offset. If you feed them at minimum values ​​they don’t work, so you have to feed them at 12v. This is done by removing the two bars in front of each #define, this way the compiler can make use of them and add them to the final firmware. Mine is between 59 and 60. If you have issues with some versions of Marlin (sometimes happen), use the ZMin connector. If you can’t find it, you can alternatively run the command M500 (Save settings). You can buy this type of sensor in any online store, since they are very common in the world of 3D printing. The next step is to change your homing files for X and Y ("homex.g" and "homey.g", and portions of "home all" if X and Y of your ""homeall.g" is configured in such a manner. You are right the sensitivity value is a pain to find. Marlin hasn’t been great in the past at being right when you combine corner cases like that, but sensorless homing and dual endstops have been out long enough, maybe it will work. Regards! Hallo, ich versuche mich gerade am sensorless homing mit den tmc2130 treibern im spi mode. Just one important thing. All the options I'm left with are that this is a firmware issue, or that this is a hardware incompatibility issue (as in my stepper motors not being compatible with stallguard on the TMC2209). Recently a colleague sent me a BLTouch / 3DTouch sensor from the Geeetech brand. if anything at all the documentaion is behind. Once the motor reaches the current setting limit, the TCL output will activate to communicate when the hard stop is reached. SPI / UART interface of the TMCxxxx wired to MCU (stand-alone mode does not work) 3. Already on GitHub? And when it is extended, it must lower several millimeters below the nozzle to be able to act. Is the schematics that you provide in your article is the good one to avoid frying a board ? You will need to add the self-leveling function at the beginning of each print. For example most would use the sensorless homing on the X and Y axis. I really would appreciate some help 👼. HYBRID_THRESHOLD: Configure the axis speed when the driver should switch between stealthChop and spreadCycle modes. Nor do I see it practical and much less precise, although at this point I surely disagree with some reader . Use this command to set the bump sensitivity for the X, Y, and Z stepper drivers. Sensorless homing is a feature that is supported by the TMC2209 stepper drivers but there is also other models that support this like the TMC 2130 for example. Regardless of where it is located with respect to the X and Y axes, which are the ones you must configure in Marlin, you have to position the BLTouch / 3DTouch sensor at a certain distance in height from your nozzle. In addition, on aluminum the detection range of capacitive and conductive sensors is considerably reduced with respect to using steel or iron. The higher the temperature, the lower the detection range. However now i have an issue with it homing, changing direction and running to the other side(both X and Y) and running till it skips belts, Then changing direction again and homing successfully. TMC2209 v1.2. I've been doing some tests, and commenting out the IMPROVE_HOMING_RELIABILITY option changes the values completely (the magic number seems to be somewhere 168/169 with the same driver). Well, let’s start configuring our Marlin firmware to support BLTouch / 3DTouch sensors. If you wish, you can find other interesting articles in 3DWork at the following links: I have a MKS SGEN LPC1769 mainboard. 50 homings - 0 "never triggered", 50 triggered as soon as it started @ X_STALL_SENSITIVITY 170 Currents set to half of what they were(400 now) and it will home now. I have no idea how to get further with this. Ezabl Pro using SKR 1.4 Turbo Probe port (P0_10) Installing and tuning the Ezabl per instructions, M119 shows open when clear of the bed and triggered when nozzle 2mm above bed. They go in correct direction from display menu. Yes, you can connect to the SKR Pro due it have dedicated connector. You can use "M906 X200 Y200" to drop your motor current to 200ma on the X and Y axis and then home, I am curious to see if other people can test this. by BTT DIAG pin was removed how told in manual. I have to say that I tried quite a few inductive and capacitive sensors, I even opted for the original PINDA 2 , which is very comfortable to install since is one of the few that actually powers 5V and gives quite a bit of precision. So I suggest you to test more to find the right value, mine are X/Y 60 and Z 94. 60 and it will stop movement during travel, 59 never triggers and runs untill printer halted. In G28.cpp I raised the acceleration rate from 100 to 500 for homing which after lots of testing allowed me to run a higher sensitivity without the steppers tripping the endstops right away when starting to move.
