Please open a new issue for related bugs. 50 homings - 5 "never triggered", 45 triggered as soon as it started @ X_STALL_SENSITIVITY 168. But for starters it is more than enough. You must measure these values to enter on your printer (do not use mine). 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). Confirmed on my end. if anything at all the documentaion is behind. 3 wire connector goes to servos. State never triggers in M119 command. Then i tried activate Sensorless homing, my X and Y motor do motion in wrong way. 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. TMC2209 v1.2. Thanks so much for this thread! The higher sensitivity also produces a much softer hit on the axises. 50 homings - 3 "never triggered", 47 triggered as soon as it started @ X_STALL_SENSITIVITY 169 This feature is so sensitive that it can actually take the place of traditional endstops. Of course, you can configure much more parameters such as limits, polls, travel speeds, etc. I downloaded the latest Marlin bugfix version which is 2.0.6 at the moment of writing this article. 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. I have gone through the datasheet and haven't seen anything that'd point to that anyway. The difference compared to Configuration.h is that it offers us more detailed customization options, and experimental or in development functions. 60 and it will stop movement during travel, 59 never triggers and runs untill printer halted. I have been doing plenty more testing and I can definitely confirm that in my case, stallguard is consistently triggering when at the start of the homing for an axis there's something bumping on the carriage (provided the sensitivity value is high enough). Also I found that 2209 have not the same sensitivity and my guess depends on the quality of the silicon. And with the BLTouch the same, since they are completely mechanical sensors (hence my desire to try it). MarlinFirmware/Marlin. 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. 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. For a sensor less homing routine, we suggest setting the current to a low setting, and moving at a slow speed toward the hard stop. I have a suspicious playing with values such as off time, blank time or hysteresis values might be the answer to solve this. Thus you would place a … With bump sensitivity at 35 for TMC2130 stepper drivers I ran 100 tests with motor current at 800ma and 200ma without changing the bump sensitivity. @hackebike 120 on both x and y running on a corexy setup. 100% success rate since I've done that! There's either some obscure parameter/combination of options to make this work (in which case having it on an issue would be helpful to others) or an actual bug in the implementation. Factory Z endstop installed as failsafe. BLTouch / 3DTouch sensors are mechanical, so they are not affected by heat, humidity or the type of material on your printing surface. Just one important thing. This way I won’t have to go corner by corner unnecessarily to calibrate my bed. Diag pin of TMC is well connected to Zmin signal, and Zmin work well when I put it to Vcc. If using stealthChop it's important to have a well tuned chopper frequency as well. In addition, on aluminum the detection range of capacitive and conductive sensors is considerably reduced with respect to using steel or iron. You should have an option called Record to EEPROM , as long as you have supported it in your Marlin. With downloaded Marlin from Fysetc Wiki no values are Stored with M500 (yes I activated the function for M500 in Marlin) Sensorless Homeing don’t work. @boelle I appreciate that you want to keep the issues down, and this may be hard to reproduce, but I've shared as much info as I can and so far I've had very few suggestions as to what I might be able to try configuration-wise. It seems to work alright, but setting up the sensorless homing is being a pain (I had it working with an TMC2130 earlier). Thank you ! I checked it twice first it seems that on TMC2209 logic is inverted high values for more sensitivity low values for less sensitivity. For example most would use the sensorless homing on the X and Y axis. I am only going to detail the steps necessary to make the TMC2209 work without sensorless homing, i won’t do a full tutorial on each option that might be required to make your specific machine work. Already on GitHub? Whatsapp: 608 361 608, © 2019–2020 3DWork - Todos los derechos reservados, Nuestro sitio web utiliza cookies para mejorar su experiencia. 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. However, you should not worry because when configuring the BLTouch sensor the options to be modified in the Marlin firmware will be exactly the same . Change your homing files' structures. Marlin can be found here. 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. will close this one as its most likely down to tune and machine setup See various YouTube videos on how to get the current well tuned with a multimeter. As you can see in this image, the BLTouch / 3DTouch leveling sensors have two connection cables. Apparently, lowering the homing speed to fairly low values fixes the issue. necessary (very important). Marlin-188.8.131.52_SKR1_4. I will point out that with the SKR v1.4, there is no way to disable sensorless homing (unlike other boards that use a jumper), and as sensorless homing is currently not supported, you will have to either remove or bend the diag pin on the TMC2209 to be able to use mechanical endstops. In this way we can continue writing 3D printing guides and articles on interest. I set my HOMING_FEEDRATE_XY to (30*60) and with that, I can set my stallguard sensitivity values at 100 and it seems to work perfectly (I haven't had a single false positive or false negative so far). Sign up for a free GitHub account to open an issue and contact its maintainers and the community. This happened me with different sensor (inductive), that needed 12v for operate properly. Setting it to (45*60) goes back to the behaviour I reported here, where it's either too sensitive or too insensitive without anything reasonable in-between. I am configuring the TMC2209 stepper drivers to run in UART mode for this, so I have to … by BTT DIAG pin was removed how told in manual. So I got down to work for Configure BLTouch with BabyStepping in the last Marlin available today and satiate my curiosity.. to your account. Hi I have a skr pro v1.2 and picked up a 3d touch the board hS a special place for the bl touch/3d touch… my 3d touch touch does not have aa connection for that spot ware would I plug it in on that board…. Currents set to half of what they were(400 now) and it will home now. by BTT DIAG pin was removed how told in manual. I'll try to add something to the docs about it. We will proceed to uncomment the USE_ZMIN_PLUG options. Specs: SKR1.3, TMC2130 Sensorless Homing, Marlin 184.108.40.206, Ender 3. Ironically, that's not the point of sensorless homing ð. Also I found that 2209 have not the same sensitivity and my guess depends on the quality of the silicon. We will start the configuration by editing the file Configuration.h with your favorite text editor (mine is Sublime). What would i change if I wasnt using the mechanical z endstop? Answer questions lovethat777. Hey, im having exactly the same issue except my endstops are now reading "open" on X/Y but the motor just stutters as if its sensitivity to sensorless homing is very low? It’s something I don’t like at all. 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). It is logically has to be within its range of action. So the question is extremely simple. Optimize the plate and frame to avoid the phenomenon of screw hole gap and screws hitting components 5. I'm using TMC 2209s on an SKR Pro. Once the type of self-leveling that we want Marlin to carry out is configured, we will indicate with the GRID_MAX_POINTS parameters the number of probes (or tests) to be carried out. And when it is extended, it must lower several millimeters below the nozzle to be able to act. For more reasons, you can install capacitive or inductive sensors, but these types of sensors vary depending on the temperature of the bed and the metal. StallGuard capable TMCxxxx stepper driver 2. You will need to add the self-leveling function at the beginning of each print. Now we must uncomment the AUTO_BED_LEVELING_BILINEAR function and then the RESTORE_LEVELING_AFTER_G28 function, so that they remain active in our firmware. Recently a colleague sent me a BLTouch / 3DTouch sensor from the Geeetech brand. The higher sensitivity also produces a much softer hit on the axises. Lowering the current before homing works perfectly for me! Sensorless homing is still out on the Z axis, can't get this currently to work regardless how much or how less power i give them. The drivers are also TMC2209 v1.2 by BTT, and I didn't cut any legs (I don't think this is needed on the ramps at all). If you have issues with some versions of Marlin (sometimes happen), use the ZMin connector. With the Eryone 2209 you can have sensorless homing without the need to bend or modify the pins. Note: when using 40*60 for homing feedrate, make sure you are stil lrunning in stealthchop mode. 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. Below I leave you two affiliate links to Amazon and Banggood. with a single search and very easily. Yes, you can connect to the SKR Pro due it have dedicated connector. This will store all the current settings in your EEPROM permanently. X, Y axis move fine (to right and back when adding +10 on the axis). I don't know if this is stallguard actually triggering, or it's a different thing, is there a way to tell when it's triggered? Regards! @407s for sensorless homing there is no need to remove the pin. I tried with M119 but it's always open (as expected, I guess) and M122 is not helping. Moreover you simply need to place a jumper connector on the DIAG pin for the axis that you wish to use. The relevant changes that need to be made to enable the options in the firmware are: Configuration.h #define EXTRUDERS 0 // … I usually use optical infrared sensors for my printers, but I wanted to try the BLTouch sensors since none had fallen yet by my hands. I was pulling my hair because in more than half cases homing failed, which sent the toolhead outside the print area to do bed probing. If you need to completely configure Marlin do not hesitate to visit the Complete guide: Configure Marlin 2.0.3 from scratch and not die trying that you also have available on our website. That caught me out for a … Of course you can buy them wherever you want, there are dozens of pages. Either way, I don't think simply closing this is helpful whatsoever. One with three pins and the other with two pins, which will be the ones we will need to connect to our electronics. This procedure is not optional. The drivers come with Jumper cables, If you use a cable from the top pin for the Diag and connect it to the Signal pin for the end stop it works. Of course, this distance is at your absolute choice, it is only a guideline value. I've got the exact same setup, except I don't use the stallguard feature of the 2130's yet. Indeed, your TMC motor currents must be tuned appropriately to your stepper motors or they can't get good readings.

My assumption was the lower acceleration was causing a false stallguard 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. Another negative point since if you use glass you will be very fair and in any failure your nozzle will go through the glass with the consequent risk of breakage. Upgrading your RAMPS 1.4 (or most any AT Mega based controllers) with the TMC2130 stepper motors might do the trick.In this instructable I will not go into the technical babble of PSI, Master/Slave… I'm going to keep playing with the sensitivity value, homing feedrates and driver current to see if I can get it to work correctly, but so far it's being a pain. I just have a question, you mention you burnt your MKS board by sending a 12V signal to a 5V pin. You signed in with another tab or window. pin 23 is signal wire. I also created a custom homing button in OctoPrint. 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. Finally remind you, as always, that you can find us on our Telegram channel full of maniacs by 3D printing at next link, or on our social networks (don’t forget to follow us if you like the web). Here is a video and the configs files in the description. @uorbe001 I have sensorless homing and probing working (after few weeks of testing) with BTT TMC 2209 v1.2 on a SKR Pro. It is simply adding the G29 command to level your head before each impression. If Marlin detects an error where the driver has shut down to protect itself, it can stop the print to save both time and material. If we use a self-leveling sensor (either BLTouch or any other), we must indicate to Marlin the position of the sensor with respect to our print nozzle. thx, 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. and have a 1mm move away after home. Hi all, after getting a couple of issues resolved on the Marlin Github, there is now a Marlin build that supports an SKR 1.3 with dual y and z endstops in TMC2209 uart mode with sensorless homing. in a 5v input. Just adding in i have this exact issue. They both are running StealthChop V2 for extremely quiet printing. Now we will save the Configuration.h file and edit a new file called Configuration_adv.h . Very easy as you have been able to check, click on those 2 sites and that’s it. Everything working as intended. Instead using thr bltouch as the z endstop? 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" For sensorless homing, the default sensitivity setting should be ok for most printers, but of course you can play with it if it is too sensitive or not sensitive enough. Now i think my problem can be only in always triggered sensor (internal in driver) after #define Sensorless homing. Stuck at maximum coordinates. 0,0 is on left bottom of the Buildplate, as usual. You can buy this type of sensor in any online store, since they are very common in the world of 3D printing. Before starting I have to confess that I do not have a commercial 3D printer as many of you may have ( Anet A8 , Ender3 or Artillery X1 for example). The higher the temperature, the lower the detection range. I really would appreciate some help ð¼. They go in correct direction from display menu. So I got down to work for Configure BLTouch with BabyStepping in the last Marlin available today and satiate my curiosity. 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). If I set the sensitivity to anything above 105 (M914 X105) and try to home the axis, it moves for about 1mm and then immediately stops. Mine is between 59 and 60. I just got (and tried) a couple of watterott TMC2209's, and I'm getting the exact same result as I was with the BTT drivers. Sensorless homing will not work with the pin removed unless you add a jumper from the top of the driver from the DIAG to x_min signal and Y_min signal. If it is, however, a firmware issue, this issue has merit and shouldn't be simply closed. Your email address will not be published. Once you have made the offset settings, don’t forget to save the value in memory. Answer questions VOIDREP. Have a question about this project? Then i activated function, mechanical switches was unpluged from board and installed special jumper in XST and YST slots. TMC2209 v1.2. Actual behavior: Stallguard triggers too early (moving 1mm and hitting nothing) with the 105 sensitivity, and too late (dangerously so) with 104. Some TMC stepper drivers can detect when they bump into something that causes them to stop moving. This function allows me to calibrate the height of my leveling sensor in the center of the bed once with a sheet of paper. 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. If you can’t find it, you can alternatively run the command M500 (Save settings). Thanks a lot for your comment! In the end, so that everything is square, you end up making several passes, especially if you are a precision maniac. [BUG] TMC2209 Sensorless Homing Not Working. SKR v1.3, and BTT 2209s. 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. Depending of the firmware version of your Marlin, in some cases it gives issues, but if you connect to ZMin it will work perfectly. Sign in Nor do I see it practical and much less precise, although at this point I surely disagree with some reader . Once the motor reaches the current setting limit, the TCL output will activate to communicate when the hard stop is reached. TFT 35 V3. As I explained in the previous article of Configure Marlin 2.0.3 from scratch, to activate the options you simply have to uncomment them. @teemuatlut sorry to mention you directly here, but you seem to be the expert in the subject. 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. Im using RAMPS 1.4 on my Hypercube with Marlin 1.1.5. If you have read the complete article, I congratulate you. A few prerequisites are needed to use sensorless homing: 1. I'm about to close it again, but I will update for the benefit of others. TMC2209 with sensorless homing on XY. Using TMC2209 and these stepper motors, on the bugfix-2.0.x branch: Expected behavior: Stallguard triggers when it hits something. I've tried to switch motor and driver with no luck. When doing sensorless endstops, it reduces the sensitivity only while homing on the affected driver, so you’ll need to make sure that works with X2 and Y2. Best regards, thank you for this little tutorial which is very useful, you forgot to mention the adjustment of the bed surface (the most important), which to change file in version 2.0 of marlin, probe_selected in the configuration_adv.h file, for what its interresse here is a link with all the explanation for this setting, https://3dprinting.stackexchange.com/questions/8153/how-to-set-z-probe-boundary-limits-in-firmware-when-using-automatic-bed-leveling. privacy statement. Now we uncomment the option Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN. I have just configured a TMC2209 for my X axis, with UART. Trastornados por la impresión 3D, Arduino y Raspberry Pi. 50 homings - 0 "never triggered", 50 triggered as soon as it started @ X_STALL_SENSITIVITY 170 i am going to try even lower motor current to test. I've setup Stallguard and Sensorless Homing for all axis. Or if you wish, you can use our component search engine Markets.sx, where you can compare prices in different Marketplaces (Amazon, Aliexpress, Banggood, etc.) DIAG1/DIAG pin of TMCxxxx connected to the MCU Later, the printer will perform 9 probe points automatically at the beginning of each print. Any chance you can confirm or deny these may affect the stallguard sensitivity? Maybe printer think, what axis already in initial position... and they triggered.... just an info, you can't have sensorless homing and endstop switches on those boards at the same time, or one or the other. That’s what Marlin is for, to make life easier for us. 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. I have always used leveling sensors on my machines, as leveling the four corners of the printing surface with a folio is definitely not my thing. SPI / UART interface of the TMCxxxx wired to MCU (stand-alone mode does not work) 3. If it is the later, I think someone should be able to point out something about it (datasheets etc, but I've been throught them and found nothing) and at the very least we should have some record for other people that this might be an issue. The DIAG pin (or what is labeled as such) is connected to my x-min. Below I leave you 2 images so you can see where the BLTouch would be connected on my board, and on a RAMPS board, much more common than the one I own. If you decide to acquire it through these links, it is my duty to tell you that a small commission will go to the 3DWork.io project and we will be eternally grateful to you. In this article we will only discuss the options to modify to support BLTouch / 3DTouch. In this way, and in real time, you can adjust the offset while you are making the first printing perimeters, and leave a perfect fit. It failed 20 tests on 800ma and failed 0 on 200ma. Furthermore, the connection of the BLTouch / 3DTouch sensors to the boards is relatively simple and you do not need to carry out any electronic modification as it happens in other sensors. 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. Direction in conf - ok. Everything else seems to work perfectly fine, but sensorless homing is either too sensitive or too little sensitive (with 1 value in between). Yes, i know. Here is a video and the configs files in the description. You can access it before the printing process and during (yes, you read me correctly) the printing process by pressing the button twice on your display. Recently a colleague sent me a BLTouch / 3DTouch sensor from the Geeetech brand. I'm using TMC 2209s on an SKR Pro. But it didn’t convince me either. I think I might have figured out why people are having issues with this. This will necessarily be separated and we will define it as coordinates and in millimeters. By clicking “Sign up for GitHub”, you agree to our terms of service and Sensitive was set 150. 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. So I suggest you to test more to find the right value, mine are X/Y 60 and Z 94. In my printer I use a leveling function available in Marlin 2 called BABYSTEPPING. 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. I don’t want to calibrate that distance again if I change the filament from PLA to ABS, it’s a hassle. So basically, it works when it's already homed. The problem is that around the "magic numbers" stallguard triggers as soon as the homing starts (without anything connected to the stepper, again) and then occasionally it will never trigger. HYBRID_THRESHOLD: Configure the axis speed when the driver should switch between stealthChop and spreadCycle modes. Beim Board handelt es sich um ein Ramps 1.4 Board mit der aktuellsten Bugfixversion 1.1.x Für das sensorless homing habe ich auf der x und y Achse dbg1 vom … My leveling BLTouch is 37mm to the right of the nozzle, and 2mm behind it, so I would put the following settings. Weâll occasionally send you account related emails. When the probe is retracted, it must be above the nozzle (otherwise we will have problems). Successfully merging a pull request may close this issue. Both the TMC 2208 and TMC 2209 both have 1/256 interpolated and native 1/256 stepping support. 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. When you turn on the printer you will see that the sensor does a little checking (unfolds and retracts the probe). 2. As of today, the fixes are in the bugfix-2.0.x branch. Irritating. Is the schematics that you provide in your article is the good one to avoid frying a board ? In the case that connecting the 2 wires to the Probe connector the sensor not works, try to connect to the ZMin connector. I have no idea how to get further with this. So you can not leave a fixed value for PLA and another for ABS. 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. To me this has saved me the odd impression, the truth is that it is quite useful. I've had sensorless homing working fine with other TMC drivers as I said above, and the only value that seems to be related (according to the config and docs) to this is not making a difference (going from too sensitive to too insensitive).
