And in this other line of the code we are going to indicate that our installed sensor is a BLTouch / 3DTouch, which for Marlin come to be the same. 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. 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. Apparently, lowering the homing speed to fairly low values fixes the issue. When you turn on the printer you will see that the sensor does a little checking (unfolds and retracts the probe). 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. necessary (very important). I'm starting to consider it may be a hardware issue with the drivers themselves, but I have no idea how to test that either. 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. 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. 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. Trastornados por la impresión 3D, Arduino y Raspberry Pi. MarlinFirmware/Marlin. Just adding in i have this exact issue. If you have issues with some versions of Marlin (sometimes happen), use the ZMin connector. 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. I've setup Stallguard and Sensorless Homing for all axis. Thank you for clarifying that. We’ll occasionally send you account related emails. Depending of the firmware version of your Marlin, in some cases it gives issues, but if you connect to ZMin it will work perfectly. Either way, I don't think simply closing this is helpful whatsoever. Note: when using 40*60 for homing feedrate, make sure you are stil lrunning in stealthchop mode. Is the schematics that you provide in your article is the good one to avoid frying a board ? I think I might have figured out why people are having issues with this. It failed 20 tests on 800ma and failed 0 on 200ma. This procedure is not optional. Already on GitHub? planner.settings.max_acceleration_mm_per_s2[X_AXIS] = 500; planner.settings.max_acceleration_mm_per_s2[Y_AXIS] = 500; @dch1921 sounds interesting, what kind of sensitivity value did you use? 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. What would i change if I wasnt using the mechanical z endstop? 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. This way I won’t have to go corner by corner unnecessarily to calibrate my bed. 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. Upgrading RAMPS 1.4 With TMC2130 Stepper Drivers: Tired of the constant noise your printer is making. 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.) 60 and it will stop movement during travel, 59 never triggers and runs untill printer halted. 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. One with three pins and the other with two pins, which will be the ones we will need to connect to our electronics. Of course, you can configure much more parameters such as limits, polls, travel speeds, etc. 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. For bltouch you not must be worried of this, just connecting to the sockets that appear in the article will feed at his correct voltage without any issue. 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. Wrong way only for G28 command. For the jumpers, each one marked in purple must be jumped: ... [BUG] TMC2209 Sensorless Homing not working hot 3 Sensitive was set 150. That’s what Marlin is for, to make life easier for us. They go in correct direction from display menu. Using the very latest Marlin 2.0 bugfix, they work as expected on my end. The 2 wire is the same as your example, but the spot that you show on the boards don’t exist on mine. that works for me correctly. I usually make 9 checkpoints before each print, you can expand or reduce it, that is up to you. 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. No sensativity setting seems to change Triggered State in M119. Currents set to half of what they were(400 now) and it will home now. And when it is extended, it must lower several millimeters below the nozzle to be able to act. The higher sensitivity also produces a much softer hit on the axises. If using stealthChop it's important to have a well tuned chopper frequency as well. 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). To me this has saved me the odd impression, the truth is that it is quite useful. [BUG] TMC2209 Sensorless homing sensitivity is off. By clicking “Sign up for GitHub”, you agree to our terms of service and Only homing on X and Y for me. Regards! The higher the temperature, the lower the detection range. 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. In addition, on aluminum the detection range of capacitive and conductive sensors is considerably reduced with respect to using steel or iron. 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). So I got down to work for Configure BLTouch with BabyStepping in the last Marlin available today and satiate my curiosity.. You must measure these values ​​to enter on your printer (do not use mine). 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. Later, the printer will perform 9 probe points automatically at the beginning of each print. 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. Also I found that 2209 have not the same sensitivity and my guess depends on the quality of the silicon. 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. SKR v1.3, and BTT 2209s. The result was that the Z- was completely unusable for me having inserted 12v. 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. So I got down to work for Configure BLTouch with BabyStepping in the last Marlin available today and satiate my curiosity. Answer questions lovethat777. Well, let’s start configuring our Marlin firmware to support BLTouch / 3DTouch sensors. It feels like what is happening is that with the higher sensitivity number, it stallguard triggers with literally nothing connected to the stepper driver as soon as it starts, and the lower sensitivity numbers never trigger. SPI / UART interface of the TMCxxxx wired to MCU (stand-alone mode does not work) 3. @hackebike 120 on both x and y running on a corexy setup. 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 … 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. something to note however. Ironically, that's not the point of sensorless homing 😂. I also created a custom homing button in OctoPrint. So the question is extremely simple. The DIAG pin (or what is labeled as such) is connected to my x-min. Just check pinout and plug it properly. Thus you would place a … 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. SENSORLESS_HOMING If you wish, you can find other interesting articles in 3DWork at the following links: I have a MKS SGEN LPC1769 mainboard. 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. Also I found that 2209 have not the same sensitivity and my guess depends on the quality of the silicon. In the end, so that everything is square, you end up making several passes, especially if you are a precision maniac. if anything at all the documentaion is behind. 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. Download files and build them with your 3D printer, laser cutter, or CNC. Whatsapp: 608 361 608, © 2019–2020 3DWork - Todos los derechos reservados, Nuestro sitio web utiliza cookies para mejorar su experiencia. 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. Now we will save the Configuration.h file and edit a new file called Configuration_adv.h . Irritating. I'm using TMC 2209s on an SKR Pro. That caught me out for a … @uorbe001 I have sensorless homing and probing working (after few weeks of testing) with BTT TMC 2209 v1.2 on a SKR Pro. What is this about This post will give guidelines on how to flash your own marlin onto a Eryone Thinker S V2 (NOT the V1) or ER20 printer. If you put the head and bed manually in the initial coordinates, then after G28 the two axes move exactly 1/2 of the maximum coordinates, then the head is parked in Z. Sensorless homing requires the use of the M913 command. I'd appreciate any help debugging this, as I suspect it's something specific to my stepper motor/driver combination rather than a general issue. Direction in conf - ok. If stealthchop is disabled or disabled by hybrid settings, it will not work. 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. I downloaded the latest Marlin bugfix version which is 2.0.6 at the moment of writing this article. When the probe is retracted, it must be above the nozzle (otherwise we will have problems). 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 . Dropped motor current. Any chance you can confirm or deny these may affect the stallguard sensitivity? See various YouTube videos on how to get the current well tuned with a multimeter. E-Mail: info@3dwork.io 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. 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? And with the BLTouch the same, since they are completely mechanical sensors (hence my desire to try it). 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 have just configured a TMC2209 for my X axis, with UART. Previously I would have to go down to 70 before I changed the homing acceleration values, I have it at 60 and 94 for z-probing, I will test with those G28.cpp changes as soon as I can. 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 will store all the current settings in your EEPROM permanently. Some Chinese sensors indicate operating ranges from 6-36v, nothing is further from reality. In my case, I use MKS Gen v1.4, so the connection couldn’t be easier (just like in RAMPS). 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. Just one important thing. I’ve got mine working but for some reason the five buttons do not work. Then i activated function, mechanical switches was unpluged from board and installed special jumper in XST and YST slots. I will go into as much detail as possible but please keep in mind that marlin is constantly being developed and changes can lead to a setting being named differently, a file being renamed and so on. It’s also a good idea to add these two lines [home bump] right after the sensitivity settings to keep the printer from bumping into the axis ends too often. 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. It doesn’t give me any sense of precision, since what I’m looking for is an immutable (or at least minimal) measurement. Then i tried activate Sensorless homing, my X and Y motor do motion in wrong way. Im using RAMPS 1.4 on my Hypercube with Marlin 1.1.5. Sensitive was set 150. 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). Thingiverse is a universe of things. In my printer I use a leveling function available in Marlin 2 called BABYSTEPPING. 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. I'm using TMC 2209s on an SKR Pro. Factory Z endstop installed as failsafe. 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. Sensorless Homing work well for X,Y and Y2, but I can't get it to work on Z. I've tried allmost every settings of sensitivity, current, and speed. 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. 50 homings - 5 "never triggered", 45 triggered as soon as it started @ X_STALL_SENSITIVITY 168. It seems to work alright, but setting up the sensorless homing is being a pain (I had it working with an TMC2130 earlier). The relevant changes that need to be made to enable the options in the firmware are: Configuration.h #define EXTRUDERS 0 // … 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? 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). This connection is similar, but you must make sure that you have the jumper activated, so we will make sure that the level sensor reaches the 5v. Here is a video and the configs files in the description. 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). Instead using thr bltouch as the z endstop? Yes, i know. Some TMC stepper drivers can detect when they bump into something that causes them to stop moving. Everything working as intended. The recommended is 2mm. I'm assuming this is the stallguard triggering, since I haven't been able to get a read with M119. X, Y axis move fine (to right and back when adding +10 on the axis). Now we uncomment the option Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN. I am configuring the TMC2209 stepper drivers to run in UART mode for this, so I have to … Thanks a lot for your comment! BLTouch / 3DTouch sensors are mechanical, so they are not affected by heat, humidity or the type of material on your printing surface. TMC2209 with sensorless homing on XY. I have gone through the datasheet and haven't seen anything that'd point to that anyway. 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. 100% success rate since I've done that! MarlinFirmware/Marlin. They both are running StealthChop V2 for extremely quiet printing. Stuck at maximum coordinates. The higher sensitivity also produces a much softer hit on the axises. TMC2209 v1.2. Onboard Sensorless homing function, which can be used by plugging in the jump cap 4. Have a question about this project? You will need to add the self-leveling function at the beginning of each print. Diag pin of TMC is well connected to Zmin signal, and Zmin work well when I put it to Vcc. 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. The sensitivity is affected by many things and so needs to be determined by trial and error, but I don't think the datasheet says anything about those three affecting the readout. So I suggest you to test more to find the right value, mine are X/Y 60 and Z 94. So basically, it works when it's already homed. 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 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. 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. 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. Here is a video and the configs files in the description. 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. A few prerequisites are needed to use sensorless homing: 1. State never triggers in M119 command. It is simply adding the G29 command to level your head before each impression. If i repeat from this position else one more time, axis again go in same direction and.... printer not reacting on any command from display menu. Recently a colleague sent me a BLTouch / 3DTouch sensor from the Geeetech brand. [BUG] TMC2209 Sensorless Homing Not Working. in a 5v input. Once you have made the offset settings, don’t forget to save the value in memory. 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). Bump sensitivity might be dependent on motor current. @boelle Thank you for reopening it. When the carriage is not homed at the time the sensorless homing starts, it'll simply keeps going until the printer is killed, or it errors with a failed homing error. I had a commercial at the beginning (a completely disaster), so I decided to design and manufacture my own to my liking and needs. privacy statement. I don’t want to calibrate that distance again if I change the filament from PLA to ABS, it’s a hassle. Below I leave you two affiliate links to Amazon and Banggood. Marlin can be found here. With the Eryone 2209 you can have sensorless homing without the need to bend or modify the pins. Very easy as you have been able to check, click on those 2 sites and that’s it. With the optical sensors, which I love, we forget about these variations since under normal conditions they do not affect the type of metal or the temperature. 3 wire connector goes to servos. Mine is between 59 and 60. The main reason for me would be not having to be leveling 4 corners with a sheet of paper or making squares in bed. I really would appreciate some help 👼. Once you have edited it, we are going to indicate to our dear Marlin that our 3D printer has a limit switch (sensor) on the Z axis. Moreover you simply need to place a jumper connector on the DIAG pin for the axis that you wish to use. Hello, thank you for your article. But for starters it is more than enough. You can buy this type of sensor in any online store, since they are very common in the world of 3D printing. Also you mention that your motor go to the wrong way, for that you need to invert the motor direction in configuration.h. TMC2209 v1.2. Of course you can buy them wherever you want, there are dozens of pages. I'll try to add something to the docs about it. As of today, the fixes are in the bugfix-2.0.x branch. I have no idea how to get further with this. If you can’t find it, you can alternatively run the command M500 (Save settings). Nor do I see it practical and much less precise, although at this point I surely disagree with some reader . I don't think closing this issue with a comment saying this is a setup issue is helpful to anyone. 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. i am going to try even lower motor current to test. But it didn’t convince me either. In each and every one of them a common denominator, the detection distance varies depending on the metal and even the temperature of the bed. You are right the sensitivity value is a pain to find. I am testing now. StallGuard capable TMCxxxx stepper driver 2. Use this command to set the bump sensitivity for the X, Y, and Z stepper drivers. This function allows me to calibrate the height of my leveling sensor in the center of the bed once with a sheet of paper. Importantly to enable sensorless homing on the board is simple. 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" Please open a new issue for related bugs. This happened me with different sensor (inductive), that needed 12v for operate properly. I've got the exact same setup, except I don't use the stallguard feature of the 2130's yet. I tried with M119 but it's always open (as expected, I guess) and M122 is not helping. to your account. 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. You are right the sensitivity value is a pain to find. Now i think my problem can be only in always triggered sensor (internal in driver) after #define Sensorless homing. latest build of marlin 2.0. all libraries up to date. 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. Thanks so much for this thread! Optimize the plate and frame to avoid the phenomenon of screw hole gap and screws hitting components 5. 2. Of course, this distance is at your absolute choice, it is only a guideline value. Answer questions VOIDREP. For the rest, I have no idea why is doing that. TFT 35 V3. This issue has been automatically locked since there has not been any recent activity after it was closed. Marlin.zip. Or alternatively, you can follow us on our social networks. I updated my start gcode to drop it to 200, home, and then bring it back to normal mA (800 in my case). 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. and have a 1mm move away after home. If it is, however, a firmware issue, this issue has merit and shouldn't be simply closed. 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. It is logically has to be within its range of action. Marlin 2.0 on the SKR 1.3 with TMC2209 and sensorless homing Configuring Marlin is very simple, so there is not much magic to get sensorless homing to work. If we make the leveling of the printing surface in the 4 corners, when you are leveling one another it is unbalanced. 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. The issue is also a tad more complicated than I thought. And since I always like to do HOMING in the center of the bed for safety, I activate the Z_SAFE_HOMING option. @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. Having a component that according to the conditions of use works differently has no meaning whatsoever. So you can not leave a fixed value for PLA and another for ABS. TLDR; The Creality machines do not need more than 1A per stepper driver and sensorless homing is useless (and inaccurate) on a printer that already has endstop switches. We will proceed to uncomment the USE_ZMIN_PLUG options. 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. The only thing that will vary will be the connections, but we will indicate some examples so that you do not have any problem in its corresponding section. If you feed them at minimum values ​​they don’t work, so you have to feed them at 12v. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. Both the TMC 2208 and TMC 2209 both have 1/256 interpolated and native 1/256 stepping support. The difference compared to Configuration.h is that it offers us more detailed customization options, and experimental or in development functions.
