marlin sensorless homing

TMC2209 v1.2. 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. If using stealthChop it's important to have a well tuned chopper frequency as well. If you have issues with some versions of Marlin (sometimes happen), use the ZMin connector. In the end, so that everything is square, you end up making several passes, especially if you are a precision maniac. 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. Optimize the plate and frame to avoid the phenomenon of screw hole gap and screws hitting components 5. I’ve got mine working but for some reason the five buttons do not work. I've got the exact same setup, except I don't use the stallguard feature of the 2130's yet. 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. As of today, the fixes are in the bugfix-2.0.x branch. 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. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. 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 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). For example most would use the sensorless homing on the X and Y axis. Wrong way only for G28 command. I'm assuming this is the stallguard triggering, since I haven't been able to get a read with M119. And with the BLTouch the same, since they are completely mechanical sensors (hence my desire to try it). Is the schematics that you provide in your article is the good one to avoid frying a board ? Weâll occasionally send you account related emails. 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. 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. I just have a question, you mention you burnt your MKS board by sending a 12V signal to a 5V pin. The 2 wire is the same as your example, but the spot that you show on the boards don’t exist on mine. TMC2209 with sensorless homing on XY. I downloaded the latest Marlin bugfix version which is 2.0.6 at the moment of writing this article. Both the TMC 2208 and TMC 2209 both have 1/256 interpolated and native 1/256 stepping support. 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. Apparently, lowering the homing speed to fairly low values fixes the issue. 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. 50 homings - 0 "never triggered", 50 triggered as soon as it started @ X_STALL_SENSITIVITY 170 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. 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. 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. I've tried to switch motor and driver with no luck. Answer questions lovethat777. 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. We will start the configuration by editing the file Configuration.h with your favorite text editor (mine is Sublime). Thank you for clarifying that. 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.) So the question is extremely simple. Indeed, your TMC motor currents must be tuned appropriately to your stepper motors or they can't get good readings. 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 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. Stuck at maximum coordinates. If you feed them at minimum values they don’t work, so you have to feed them at 12v. that works for me correctly. 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. SKR v1.3, and BTT 2209s. The DIAG pin (or what is labeled as such) is connected to my x-min. X, Y axis move fine (to right and back when adding +10 on the axis). If you have read the complete article, I congratulate you. 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. 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). This procedure is not optional. I'll try to add something to the docs about it. Use this command to set the bump sensitivity for the X, Y, and Z stepper drivers. on the skr pro manual it states that you cut it if you want to use endstop switches, you keep it if you using sensorless homing/probing. For the rest, I have no idea why is doing that. In my case, I use MKS Gen v1.4, so the connection couldn’t be easier (just like in RAMPS). When the probe is retracted, it must be above the nozzle (otherwise we will have problems). Sensorless homing requires the use of the M913 command. Answer questions VOIDREP. 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. by BTT DIAG pin was removed how told in manual. Marlin can be found here. Everything else seems to work perfectly fine, but sensorless homing is either too sensitive or too little sensitive (with 1 value in between). Onboard Sensorless homing function, which can be used by plugging in the jump cap 4. Very easy as you have been able to check, click on those 2 sites and that’s it. 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. My leveling BLTouch is 37mm to the right of the nozzle, and 2mm behind it, so I would put the following settings. You are right the sensitivity value is a pain to find. Trastornados por la impresión 3D, Arduino y Raspberry Pi. 3 wire connector goes to servos. The higher sensitivity also produces a much softer hit on the axises. Depending of the firmware version of your Marlin, in some cases it gives issues, but if you connect to ZMin it will work perfectly. Why not install a leveling sensor to level at a single central point in the bed (SAFE_HOMING), and let Marlin generate the mesh of points and worry about the rest? For the jumpers, each one marked in purple must be jumped: ... [BUG] TMC2209 Sensorless Homing not working hot 3 You signed in with another tab or window. Whatsapp: 608 361 608, © 2019–2020 3DWork - Todos los derechos reservados, Nuestro sitio web utiliza cookies para mejorar su experiencia. Thus you would place a … If it is, however, a firmware issue, this issue has merit and shouldn't be simply closed. Instead using thr bltouch as the z endstop? SPI / UART interface of the TMCxxxx wired to MCU (stand-alone mode does not work) 3. One with three pins and the other with two pins, which will be the ones we will need to connect to our electronics. Currents set to half of what they were(400 now) and it will home now. Thanks a lot for your comment! It seems to work alright, but setting up the sensorless homing is being a pain (I had it working with an TMC2130 earlier). 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. 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. 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. Bump sensitivity might be dependent on motor current. Factory Z endstop installed as failsafe. Only homing on X and Y for me. necessary (very important). Now we will save the Configuration.h file and edit a new file called Configuration_adv.h . I'm about to close it again, but I will update for the benefit of others. This will necessarily be separated and we will define it as coordinates and in millimeters. 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. Here is a video and the configs files in the description. 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. 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. pin 23 is signal wire. I really would appreciate some help ð¼. 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. Lowering the current before homing works perfectly for me! Importantly to enable sensorless homing on the board is simple. Some TMC stepper drivers can detect when they bump into something that causes them to stop moving. 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 … Configuring Marlin is very simple, so there is not much magic to get sensorless homing to work. @uorbe001 I have sensorless homing and probing working (after few weeks of testing) with BTT TMC 2209 v1.2 on a SKR Pro. As soon as I change the sensitivity to anything bellow that (M914 X104) it just tries to home forever until I kill the machine. So I got down to work for Configure BLTouch with BabyStepping in the last Marlin available today and satiate my curiosity. @boelle Thank you for reopening it. And when it is extended, it must lower several millimeters below the nozzle to be able to act. [BUG] TMC2209 Sensorless homing sensitivity is off. will close this one as its most likely down to tune and machine setup So I suggest you to test more to find the right value, mine are X/Y 60 and Z 94. 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. I'm using a RAMPS 1.4 board, sorry I didn't specify this earlier. This feature is so sensitive that it can actually take the place of traditional endstops. The relevant changes that need to be made to enable the options in the firmware are: Configuration.h #define EXTRUDERS 0 // … if anything at all the documentaion is behind. 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. You should have an option called Record to EEPROM , as long as you have supported it in your Marlin. Same setup here SKR 1.3, and BTT TMC2209 v1.2, was having the same problem using source from BTT repositories, my situation was trying to home to XMax and YMax, found 2 possible solution 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 updated my start gcode to drop it to 200, home, and then bring it back to normal mA (800 in my case). Some Chinese sensors indicate operating ranges from 6-36v, nothing is further from reality. Then i activated function, mechanical switches was unpluged from board and installed special jumper in XST and YST slots. @teemuatlut sorry to mention you directly here, but you seem to be the expert in the subject. Using TMC2209 and these stepper motors, on the bugfix-2.0.x branch: Expected behavior: Stallguard triggers when it hits something. So basically, it works when it's already homed. I have gone through the datasheet and haven't seen anything that'd point to that anyway. Activating sensorless homing is pretty straightforward but, if you want to get stallguard information on the z axis, it requires to plug the Bl-Touch in the Z max pin instead of the Z min. Yes, i know. Diag pin of TMC is well connected to Zmin signal, and Zmin work well when I put it to Vcc. The higher the temperature, the lower the detection range. privacy statement. 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. 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. 60 and it will stop movement during travel, 59 never triggers and runs untill printer halted. You can buy this type of sensor in any online store, since they are very common in the world of 3D printing. Having a component that according to the conditions of use works differently has no meaning whatsoever. Sign in The result was that the Z- was completely unusable for me having inserted 12v. It failed 20 tests on 800ma and failed 0 on 200ma. Regards! 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. Well, let’s start configuring our Marlin firmware to support BLTouch / 3DTouch sensors. Specs: SKR1.3, TMC2130 Sensorless Homing, Marlin 2.0.5.3, Ender 3. Nor do I see it practical and much less precise, although at this point I surely disagree with some reader . 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? The recommended is 2mm. Trastornados por la impresión 3D, Arduino y Raspberry Pi. Note: when using 40*60 for homing feedrate, make sure you are stil lrunning in stealthchop mode. 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.
