* You can finetune the reading by changing the STALL_VALUE. 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. whats the result ? Sensorless Homeing requires the the TMC2130 to be in spreadcycle Mode. However, it works the same with all other axes (that require an end stop). Sign in I bought my TMC2130 from Watterott which I assume to be a reliable distributor, not selling cheap Chinese clones (or at least somehow denote it). … * A higher STALL_VALUE will make the reading less sensitive and. On some TM… Sensorless homing allows to home an axis without the need for a physical limit switch. Not even if I type the + in the terminal or -, if I type 0 it releases the axis and with 1 it locks again. See THIS image. You signed in with another tab or window. If you wish you to use another axis, you need to change the pin definitions accordingly, along with the step port (PORTF as default) and pin bit position (0 as default). What does the serial output look like? Instead, the TMC2130 can be used as a sensor. 0 1023 979 The rest sounds ok to me. If everything works correctly, the output should look similar to this (in OctoPrint terminal tab): The actual register values might differ based the configuration of your TMC2130. For info, I'm using an Arduino mega 2560 with a ramps 1.5. Taking a closer look at the example output, it would suggest a communication error. So not exclusevely but at least for the homeing process. Some TMC stepper drivers can detect when they bump into something that causes them to stop moving. I just wanted to activate even Sensorless Homing ... Did you change anything in the example before uploading? I tried again to open the StallGuard example, just changed the SPI pins to hit my Y-axis pins on my Ramps (see attached). 0 1023 979. TMC2130_SG_HOMING is just a flag, so the specific value has no meaning except being different from 0. Will these settings overheat the driver? Values have to be in between -64 (most sensitive) and 64 (least sensitive). G-Codes: Information on commands supported by Klipper. MKS Gen-L v1.0 & TMC2130 Drivers Wiring for SPI and Sensor-less Homing X_ Dia g n o stics Y_ Dia g n o stics X_ CS Y_ CS Z _ CS S D O S C K S D I S S GND D6 3 D4 0 D4 2 D6 5 5 V D5 9 D6 4 D4 4 D6 6 D4 9 … 1023 = 0b1111111111 and 979 would be close to irun = 0b11111 when vsense = 1. My endstops and TMC configuration looks like this: I did a test running the StallGuard TMC2130 Sketch and I connected an LED to the DIAG1 and the GND of the Ramps, but when the motor starts to turn the LED is already on and the terminal does not change any value even if I put some pressure on the motor shaft. Are you sure you're not hitting #10629 (comment) ? The configuration however is simailar to the other TMCs with StallGuard: The above snippet configures a TMC2130 for the stepper on the X axis. My Step Drivers are from a new version of Fystec that already comes with 0ohm resistors welded on the CFG4 and CFG5, and without the SPI resistor. Make sure to fill in the missing values based on your configuration. To make the StallGuard instance work, I copied the part from rotating the Simple Example engine. In stealthchop sensoless homing won't work at all. That supports all you need for tmc drivers and works stable. Especially spindles (on the Z axis) might generate a lot of force. Will I have any of these problems with the configuration I have set above? The example uses direct register manipulation. I'm in a dilemma for setting up the sensorless homing with the TMC2130 drivers, with Ramps 1.4 and Arduino Mega. With the LR2, there are a couple things to watch out for before you ruin your CNC, as it’s not designed for sensorless homing (or homing … I suggest you first try to get the example working. Further, sensorless homing might not be accurate enough for you printer. This means, the stepper driver pulls the pin low to indicate a stalled motor (active low) and the pin must be inverted by adding a ! Let’s try the first sensorless homing now. actually i didn't care about it in the first place but it was important. And it definitely has to do with sh as the only axis that will move for me is the one that doesn’t use sh, my z axis. TMC2130_TCOOLTHRS sets the speed above which StallGuard (= your homing signal) will be enabled (BUT: high TCOOLTHRS value = low speed). And the output is the same as I sent above, same values ​​... You commented about my engines needing a positive signal .. My engines are simple Nema17, worked with the A4988 and worked first with the TMC2130 except for Sensorless Homing. By clicking “Sign up for GitHub”, you agree to our terms of service and SKR V1.4 Turbo with TMC2130 in SPI mode with sensorless homing I have just received my new board (upgrade for Ender 3 Pro) and can't find info regarding connection of the supplied loom. Any value I put in STALL_VALUE does not affect the behavior at all. @mbuc My HOMING_FEEDRATE_XY was 3000, very slow.. How it could affect the working of sensorless homing? i.e. As long as the Diag1 pin is connected to X-min endstop pin on the board (and Y) it should work. They already have the CFG4 and CFG5 with a small resistor, without the SPI resistor and already with the SPI pins welded up. See my demo video with the RAMPS - I'm only using one TMC2130 on that board, on X. The driver_SGT value describes the threshhold when the driver reports a stall. This issue has been automatically locked since there has not been any recent activity after it was closed. * a lower STALL_VALUE will make it more sensitive. In order for klipper to correctly configure the driver for sensorless homing, the correct configuration property name diag0_pin or diag1_pin must be used. I am setting the maximum to 1838.5 mA (that's Okay) and the motor RMS is 1.3 A (more than 1.2 A). The TMC2130 can run in two modes: spreadCycle of … 0 1023 979 Hi, i test the new driver tmc2130 with homing sensorless and work perfect for X and Y axis, its possible implement new feature for use sensorless for Z probe?, i don´t know how about the precission of sensorless … I bought these from china already in the SPI-enabled version in the hope of being easy to configure the sensorless homing. The problem arises with "stallguard". My plan was to issue a command in the adv_config with this command : I'll have to try later on this week when I have time. Depends which TMC2130 sou have. The values can be any interger between -64 and 63. More advice: 0 1023 979 * Plot TMC2130 motor load using the stallGuard value. Lowrider 2, 5'x10', Dual Endstops, Sensorless Homing, SKR 1.3, TMC2130. It is not sufficient to use only one signal from one of the stepper drivers (as it is possible on e.g. @comps If your PCB has no external pull-up, you can enable the internal pull-up of your MCU by adding a ^ in front of the pin name. Each stepper driver constantly monitors the motor current that it is delivering … Further, at very high speeds, the back EMF of the motor approaches the supply voltage of the motor, so the TMC cannot detect stalls anymore. @rodrigosclosa Have you tried reducing HOMING_FEEDRATE_XY? Does it help? I only changed the Y_CS, the others are unchanged. Even if I change the STALL_VALUE to 63 the same happens. LowRider CNC. Right. But Sensorless Homing can not enable .. Is already any solution that you forgot to post it? You can use this instead of a physical end stop pin by changing the endstop_pin of the corresponding axis: The name of the virtual end stop pin is derived from the name of the TMC2130 section. @teemuatlut How can I do that? Does anyone know what could be wrong? Attached are also my Marlin Configuration and Configuration_adv files bugfix_2.0.x. I didn't need to do anything but I did change STALL_VALUE to 10 so that I could see coolStep working properly. I already used a TMC2130 before I bought it without being SPI and had to make the modifications to make it work with SPI (I followed the tips of topics here). If Watterott you have to close the SPI solder Bridge in order have them in standalone. I've had the same issue, by the way. Just sayin', because, unfortunately, I couldn't find a solution either. 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. The device has an integrated microstepping indexer, the sensorless stall detection technology StallGuard2™, the sensorless … I did not find any instruction on this .. Just saying that Home is always done using spreadCycle .. Be aware that Klipper needs both DIAG1 pins connected to the MCU. S CURVE ACCELERATION should be disabled. Sensorless homing … Successfully merging a pull request may close this issue. Which Firmware are you on? The _MICROSTEPS setting is a bit confusing but, if you had 3 jumpers underneath your old driver leave it at 16, The interpolation will still bring it to 256. The TMC2130 provides an integrated motor driver solution for 3D-Printing, Cameras, Scanners and other automated equipment applications. You’re lucky I had to revert to an April build of bugfix as I tried to install today’s bugfix and I got absolutely no working tmc2130s. Use this … Further, the stall detection of the stepper driver is dependant on the mechanical load on the motor, the motor current and the motor temperature (coil resistance). On some TMCs like the TMC2209 this value doesn’t exist in this form as the hehavior is different to the TMC2130. The text was updated successfully, but these errors were encountered: Hi, I run my steppers at STALL_VALUE 1. I tested it with Marlin versions 1.1.8, bugfix-1.1.x and bugfix-2.0.x. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. I'll try to put just 1 to test. Values have to be in between -64 (most sensitive) and 64 (least sensitive). I'm about to change my set for a MKS Rumba + .. At this point, your axis should be able to home based on the stall detection of the TMC2130. It also does not work for me .. This information can be used by Klipper as end stop for the axis. Which is used is determined by which driver pin is connected to the MCU pin. Issue was not solved and the topic is closed ! Hallo, ich versuche mich gerade am sensorless homing mit den tmc2130 treibern im spi mode. ... /** * TMC2130… There are many other options to configure on a TMC2130, make sure to take a look at config reference for all the available options. During homing, you need StallGuard to be enabled no … Sensorless homing: Configuring tmc2130 sensorless homing. Steppers work fine under Marlin, direction and all. For very slow speeds (less than 10 RPM) the motor does not generate significant back EMF and the TMC cannot reliably detect motor stalls. On a RAMPS board the Y step pin is D60 which is in PORTF as pin number 6. Your Builds. To use sensorless homing, can not I leave stealthChop enabled? Homing a delta printer sensorless is not advisable due to missing accuracy. ... [BUG] TMC2209 Sensorless Homing … Lately the new electronic boards of the company BigTreeTech (SKR V1.4 and SKR 1.4 Turbo) are enjoying quite a notoriety within the world of 3D printing. @teemuatlut Congratulations! I've tried to tune up rising from 0 to +63 and from 0 to -64. You should configure and tune it for one axis at a time. Please open a new issue for related bugs. Does anyone have any light or tips to give me what else can I test? In none of them can I activate sensorless homing detection. Have a look at the datasheet of your specific TMC to avoid mistakes. Change limit switches pins, … But any value I put in STALL_VALUE does not affect anything. Even if your axis homed correctly, it might be worth to try a few different values for driver_SGT. in front of the pin name. The value is not reflected in the M112 command nor the initial echo out when i connect to the board. ... there two more things we need to enable and those are the automatic current tuning and the sensorless homing… But either no luck. But the sensorless homing I can not activate at all! In other words, everything read from the driver would be read as HIGH. * You can control the rotation speed with. 0 1023 979 This guide covers the setup of sensorless homing for the X axis of your (cartesian) printer. First try to get the stallGuard example working. Where do I need to change the PORTF and the pin position? 0 1023 979 Start ... If you have a CoreXY machine, you can configure one stepper driver for X and the other for Y homing as you would on a cartesian printer. The output does not change when I put load on the motors. nedwardnz (Ned van Geffen) November 23, 2019, 10:32am #1. It will likely not work as intended. * and the stall flag will be triggered. … The stepper driver senses the lost steps and indicates this to the controlling MCU (Klipper) by toggling a pin. Marlin). : understand that this will not work with a stock cr-10, cr-10s, cr-10s4/5 etc. @lucassing i finally solved my own problem by soldering small tiny jumpers to enable sensor-less homing. Change your homing files' structures. StallGuard capable TMCxxxx stepper driver, SPI / UART interface of the TMCxxxx wired to MCU (stand-alone mode does not work), DIAG1/DIAG pin of TMCxxxx connected to the MCU, The axis stops moving before hitting the mechanical limit or does not move at all, The axis homes correctly (which is unlikely at this point), The axis bumps into the mechanical limit and keeps moving while making horrible noise. I havent tried stall detection yet though. In Marlin the switch to spreadcycle for Homing … Hey everyone, I somehow … This version is sold on Aliexpress: https://en.aliexpress.com/item/4X-MKS-TMC2130-V1-1-To-Stepstick-Stepper-Motor-Driver-de-Fun-o-SPI-with-Dissipador/32850172695.html?spm= a2g0s.9042311.0.0.38b2b90a7GC1In. Developer Documentation. 0 1023 979 One strange thing I noticed in the bugfix-1.1.x branch is that the direction of rotation of the motor is changed if I use negative value. 0 1023 979 Sensorless homing is simply having no physical sensors mounted on the printer. If the register values are all ffffffff or look otherwise bogus (for example, LOST_STEPS should be always 00000000 here) make sure that the SPI is wired and configured correctly. If you want to add sensor-less homing to your cr-10 and have the tmc2130 … A few prerequisites are needed to use sensorless homing: Be sure that your mechanical components are able to handle the load of the carriage bumping into the limit of the axis repeatedly. The TMC2130 and TMC5160 have both a diag0_pin and diag1_pin in most known hardware the diag1_pin is appropriate. In this guide we’ll be using a TMC2130. But do you have any tips on what could be wrong and I can not enable the Sensorless homing in Marlin? Home the X axis by sending the following G-Code command to Klipper and observe the outcome: If the axis stopped early (first outcome), the stepper driver detected a motor stall even though there was none. While homing X and Y axes on a cartesian machine can work well, homing the Z axis is generally not accurate enough and results in inconsistent first layer height. The driver_SGT value describes the threshhold when the driver reports a stall. The higher the value, the later it triggers stall detection. For Marlin, I have not been able to make it work either. So you should test values like 1, 0 or even -10 or so. The TMC2130 is a stepper motor driver that is specifically designed for 3D printers – and it works so well that even Prusa is using it on their new MK3! Same here, why did you close it @boelle?
