In this way we can continue writing 3D printing guides and articles on interest. 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. 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? 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. Diag pin of TMC is well connected to Zmin signal, and Zmin work well when I put it to Vcc. Also I found that 2209 have not the same sensitivity and my guess depends on the quality of the silicon. It doesn’t give me any sense of precision, since what I’m looking for is an immutable (or at least minimal) measurement. Below I leave you two affiliate links to Amazon and Banggood. We will proceed to uncomment the USE_ZMIN_PLUG options. 2. You are right the sensitivity value is a pain to find. HYBRID_THRESHOLD: Configure the axis speed when the driver should switch between stealthChop and spreadCycle modes. 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. SENSORLESS_HOMING When the probe is retracted, it must be above the nozzle (otherwise we will have problems). The higher sensitivity also produces a much softer hit on the axises. As soon as I change the sensitivity to anything bellow that (M914 X104) it just tries to home forever until I kill the machine. One with three pins and the other with two pins, which will be the ones we will need to connect to our electronics. Only homing on X and Y for me. Nor do I see it practical and much less precise, although at this point I surely disagree with some reader . 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. Confirmed on my end. 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. As I have seen in some places, but it was a little short after some tests and I decided to set it to 2.5mm. Sign in I updated my start gcode to drop it to 200, home, and then bring it back to normal mA (800 in my case). 100% success rate since I've done that! 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 … I’ve got mine working but for some reason the five buttons do not work. This way I won’t have to go corner by corner unnecessarily to calibrate my bed. @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. 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. I'll try to add something to the docs about it. 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. Direction in conf - ok. Im using RAMPS 1.4 on my Hypercube with Marlin 1.1.5. Some TMC stepper drivers can detect when they bump into something that causes them to stop moving. 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" MarlinFirmware/Marlin. 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. 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.

If you wish, you can find other interesting articles in 3DWork at the following links: I have a MKS SGEN LPC1769 mainboard. 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. Either way, I don't think simply closing this is helpful whatsoever. Wrong way only for G28 command. 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 always used leveling sensors on my machines, as leveling the four corners of the printing surface with a folio is definitely not my thing. It is logically has to be within its range of action. The recommended is 2mm. necessary (very important). When you turn on the printer you will see that the sensor does a little checking (unfolds and retracts the probe). 50 homings - 3 "never triggered", 47 triggered as soon as it started @ X_STALL_SENSITIVITY 169 The difference compared to Configuration.h is that it offers us more detailed customization options, and experimental or in development functions. @uorbe001 I have sensorless homing and probing working (after few weeks of testing) with BTT TMC 2209 v1.2 on a SKR Pro. Irritating. They go in correct direction from display menu. @teemuatlut sorry to mention you directly here, but you seem to be the expert in the subject. I usually make 9 checkpoints before each print, you can expand or reduce it, that is up to you. The issue is also a tad more complicated than I thought. 60 and it will stop movement during travel, 59 never triggers and runs untill printer halted. Currents set to half of what they were(400 now) and it will home now. Depending of the firmware version of your Marlin, in some cases it gives issues, but if you connect to ZMin it will work perfectly. 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). 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. State never triggers in M119 command. Factory Z endstop installed as failsafe. [BUG] TMC2209 Sensorless homing sensitivity is off. Lowering the current before homing works perfectly for me! SKR v1.3, and BTT 2209s. 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? 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. So I got down to work for Configure BLTouch with BabyStepping in the last Marlin available today and satiate my curiosity. This happened me with different sensor (inductive), that needed 12v for operate properly. 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 TMC 2209s on an SKR Pro. I also created a custom homing button in OctoPrint. In the end, so that everything is square, you end up making several passes, especially if you are a precision maniac. Very easy as you have been able to check, click on those 2 sites and that’s it. And since I always like to do HOMING in the center of the bed for safety, I activate the Z_SAFE_HOMING option. 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 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. Dropped motor current. I have just configured a TMC2209 for my X axis, with UART. Also you mention that your motor go to the wrong way, for that you need to invert the motor direction in configuration.h. This will necessarily be separated and we will define it as coordinates and in millimeters. privacy statement. If using stealthChop it's important to have a well tuned chopper frequency as well. Optimize the plate and frame to avoid the phenomenon of screw hole gap and screws hitting components 5. 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 don’t want to calibrate that distance again if I change the filament from PLA to ABS, it’s a hassle. 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. By clicking “Sign up for GitHub”, you agree to our terms of service and 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. You signed in with another tab or window. Everything else seems to work perfectly fine, but sensorless homing is either too sensitive or too little sensitive (with 1 value in between). To me this has saved me the odd impression, the truth is that it is quite useful. 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. The 2 wire is the same as your example, but the spot that you show on the boards don’t exist on mine. I'm assuming this is the stallguard triggering, since I haven't been able to get a read with M119. 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. I tried with M119 but it's always open (as expected, I guess) and M122 is not helping. I am testing now. Thank you for clarifying that. They both are running StealthChop V2 for extremely quiet printing. Well, let’s start configuring our Marlin firmware to support BLTouch / 3DTouch sensors. I've setup Stallguard and Sensorless Homing for all axis. 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. I spent the last couple of hours trying multiple things, and it looks like I managed to find a fix for the issue. Here is a video and the configs files in the description. something to note however. 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. This procedure is not optional. Having a component that according to the conditions of use works differently has no meaning whatsoever. 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. Disabled Quick home. Both Z motors dock on for a while at the top with a long 'brrrrrrrrrrrrrrrr-brrrrrr', instead of the quick 'br-br' that X and Y now do. If you have read the complete article, I congratulate you. I checked it twice first it seems that on TMC2209 logic is inverted high values for more sensitivity low values for less sensitivity. TMC2209 v1.2. I really would appreciate some help 👼. 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? So basically, it works when it's already homed. Some Chinese sensors indicate operating ranges from 6-36v, nothing is further from reality. I've tried to switch motor and driver with no luck. Stuck at maximum coordinates. Download files and build them with your 3D printer, laser cutter, or CNC. 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. @407s for sensorless homing there is no need to remove the pin. 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. 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 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. It seems to work alright, but setting up the sensorless homing is being a pain (I had it working with an TMC2130 earlier). StallGuard capable TMCxxxx stepper driver 2. You should have an option called Record to EEPROM , as long as you have supported it in your Marlin. Then i activated function, mechanical switches was unpluged from board and installed special jumper in XST and YST slots. 3 wire connector goes to servos. Marlin can be found here. latest build of marlin 2.0. all libraries up to date. 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. In addition, on aluminum the detection range of capacitive and conductive sensors is considerably reduced with respect to using steel or iron. 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'm about to close it again, but I will update for the benefit of others. Just adding in i have this exact issue. Yes, i know. If stealthchop is disabled or disabled by hybrid settings, it will not work. With the Eryone 2209 you can have sensorless homing without the need to bend or modify the pins. i am going to try even lower motor current to test. Here is a video and the configs files in the description. 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. So I suggest you to test more to find the right value, mine are X/Y 60 and Z 94. I just have a question, you mention you burnt your MKS board by sending a 12V signal to a 5V pin. 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. It just seems impossible to find the correct number. We will start the configuration by editing the file Configuration.h with your favorite text editor (mine is Sublime). 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. Thingiverse is a universe of things. 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. Regards! 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. by BTT DIAG pin was removed how told in manual. Yes, you can connect to the SKR Pro due it have dedicated connector. 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. 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. Just one important thing. 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. 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. 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. Sensorless homing requires the use of the M913 command. 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. Bump sensitivity might be dependent on motor current. Thank you ! Indeed, your TMC motor currents must be tuned appropriately to your stepper motors or they can't get good readings. In this article we will only discuss the options to modify to support BLTouch / 3DTouch. If you can’t find it, you can alternatively run the command M500 (Save settings). @boelle Thank you for reopening it. 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. It's problem only if i activated Sensorless homing. 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.
