The stepper driver senses the lost steps and indicates this to the controlling MCU (Klipper) by toggling a pin. 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. 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. I bought these for not having been able to enable the sensorless homing in the old as well. TMC2130_SG_HOMING is just a flag, so the specific value has no meaning except being different from 0. Interestingly when i set this command : ` # define SENSORLESS_HOMING // TMC2130 only # if ENABLED(SENSORLESS_HOMING) # define X_HOMING_SENSITIVITY-1 # define … I bought these from china already in the SPI-enabled version in the hope of being easy to configure the sensorless homing. It also does not work for me .. There are many other options to configure on a TMC2130, make sure to take a look at config reference for all the available options. To … Even if I change the STALL_VALUE to 63 the same happens. There are three possible outcomes of this experiment: If the third outcome happens to you, disable the stepper (by cutting the power or issuing a M112 emergency stop). Will the TMC2130 … Is already any solution that you forgot to post it? 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). to your account. I just added a pin to DIAG1 (which is the pad closest to the potentiometer). The higher the value, the later it triggers stall detection. 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. This information can be used by Klipper as end stop for the axis. Be aware that Klipper needs both DIAG1 pins connected to the MCU. Instead, the TMC2130 can be used as a sensor. The Led is lit all the time. 1023 = 0b1111111111 and 979 would be close to irun = 0b11111 when vsense = 1. I did not find any instruction on this .. Just saying that Home is always done using spreadCycle .. 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. In stealthchop sensoless homing won't work at all. The device has an integrated microstepping indexer, the sensorless stall detection technology StallGuard2™, the sensorless … SKR 1.3 and TMC2130 SPI communication failure Using this SKR 1.3 board which shipped with the TMC2130 drivers and latest version (as of 03/08/19) bugfix 2.0.x. M915: TMC_Z_CALIBRATION (Deprecated in Marlin 2.0.) The text was updated successfully, but these errors were encountered: Hi, I run my steppers at STALL_VALUE 1. Values have to be in between -64 (most sensitive) and 64 (least sensitive). * You can control the rotation speed with. * Plot TMC2130 motor load using the stallGuard value. Finally change pins according to our connection on board. I'm in a dilemma for setting up the sensorless homing with the TMC2130 drivers, with Ramps 1.4 and Arduino Mega. 0 1023 979 Hallo, ich versuche mich gerade am sensorless homing mit den tmc2130 treibern im spi mode. But the sensorless homing I can not activate at all! Your Builds. If you want to add sensor-less homing to your cr-10 and have the tmc2130 … Congratulations! I too am having kinda the same problem with the tmc2130. Each stepper driver constantly monitors the motor current that it is delivering … But the TMC drivers are working perfectly on the printer, I already printed several parts with them .. I suggest you first try to get the example working. It is not sufficient to use only one signal from one of the stepper drivers (as it is possible on e.g. Just sayin', because, unfortunately, I couldn't find a solution either. They already have the CFG4 and CFG5 with a small resistor, without the SPI resistor and already with the SPI pins welded up. Successfully merging a pull request may close this issue. See THIS image. * This will let you control at which load the value will read 0. In order to have stealthchop in standalone enabled if the pins are … The examples also don't work. 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. This will also set pin DIAG1 high. I suppose it would be possible that your particular motors need a negative threshold value and that somehow is bugged. Even if your axis homed correctly, it might be worth to try a few different values for driver_SGT. For very slow speeds (less than 10 RPM) the motor does not generate significant back EMF and the TMC cannot reliably detect motor stalls. I have now updated the Arduino lib from the TMC2130 to version 2.4.3 and also had the same behavior. The resulting line might look like this: By configuring the diag1_pin, Klipper allows you to use a special virtual end stop for the axis. Hey everyone, I somehow … I tried again to open the StallGuard example, just changed the SPI pins to hit my Y-axis pins on my Ramps (see attached). The output does not change when I put load on the motors. To enable sensorless homing add a section to configure the TMC stepper driver to your printer.cfg. SENSORLESS_HOMING: Set SENSORLESS_HOMING sensitivity. @rodrigosclosa Have you tried reducing HOMING_FEEDRATE_XY? Homing a delta printer sensorless is not advisable due to missing accuracy. However, your M122 output looks fine. 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. 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. What does the serial output look like? Lowrider 2, 5'x10', Dual Endstops, Sensorless Homing, SKR 1.3, TMC2130. 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. Sensorless homing is simply having no physical sensors mounted on the printer. .. 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. Homing a Z axis by bumping the nozzle into the printing surface might not be a good idea. The homing thresholds seem to be hard-coded (and there is no G-Code command for … 0 1023 979 In the case of the TMC2209 the threshold is defined by the driver_SGTHRS value in the config and go from 0 (least sensitive) to 255 (most sensitive). I have set up the SPI pins correctly and my engine only makes a noise and does not spin, even if I type + several times in the terminal to increase the speed. In none of them can I activate sensorless homing detection. That's interesting... From my own experience with the latest bugfix versions of Marlin and Tmc2130 I would try your config first with the proven 1.1.8 version. The way you "enable" a driver in Configuration.h is by adding a line for it's CS pin. Please open a new issue for related bugs. That supports all you need for tmc drivers and works stable. I didn't need to do anything but I did change STALL_VALUE to 10 so that I could see coolStep working properly. The drivers are labelled as "BIGTREETECH TMC2130 v3.0". 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. I followed this guide too, but without success: http://marlinfw.org/docs/hardware/tmc_drivers.html. The configuration however is simailar to the other TMCs with StallGuard: The above snippet configures a TMC2130 for the stepper on the X axis. 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 tmc2130 … I just tried it with a FYSETC v1.1 driver and the example does work for sure. For Marlin, I have not been able to make it work either. Especially spindles (on the Z axis) might generate a lot of force. Level your X axis by trying to move the Z axis past its physical limit. I tested it with Marlin versions 1.1.8, bugfix-1.1.x and bugfix-2.0.x. In other words, everything read from the driver would be read as HIGH. To trigger stall detection at a higher load, increase the value of driver_SGT (for example from 0 to 5). This issue has been automatically locked since there has not been any recent activity after it was closed. Have a question about this project? If you think that it bumps too hard into the mechanical limit, try to decrease the value by 1 or 2. The rest sounds ok to me. I have a SKR 1.3 with TMC2130’s and dual endstops on Y and Z and sensorless homing on all axis. this was designed to completely enclose the xaxis belt drive and is only useful for sensorless homing! Sensorless homing works best at medium motor speeds. Sorry for the delay, but I tested the example sketch with the X-axis. Instead, the carriage on the axis is moved into the mechanical limit making the stepper motor lose steps. At this point, your axis should be able to home based on the stall detection of the TMC2130. Will I have any of these problems with the configuration I have set above? Issue was not solved and the topic is closed ! whats the result ? G-Codes: Information on commands supported by Klipper. Sensorless homing allows to home an axis without the need for a physical limit switch. So you should test values like 1, 0 or even -10 or so. 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). Which Firmware are you on? Where do I need to change the PORTF and the pin position? Does anyone know what could be wrong? MAX FEED-RATE and ACCELERATIONS should be reduced in order to not to lose steps and avoid layer shifting. @mbuc My HOMING_FEEDRATE_XY was 3000, very slow.. How it could affect the working of sensorless homing? To use sensorless homing, can not I leave stealthChop enabled? To make the StallGuard instance work, I copied the part from rotating the Simple Example engine. The drivers work perfectly with Marlin, I'm printing with them. Make sure to fill in the missing values based on your configuration. 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. But do you have any tips on what could be wrong and I can not enable the Sensorless homing in Marlin? The value is not reflected in the M112 command nor the initial echo out when i connect to the board. It will likely not work as intended. Does it help? S CURVE ACCELERATION should be disabled. The homing_retract_dist setting should be set to zero to disable the second homing move as a second pass is not needed, and attempts to do so are error prone. The … For info, I'm using an Arduino mega 2560 with a ramps 1.5. Without touching anything else on the firmware configuration, only the sensitivity of the sensorless homing. The TMC2130 and TMC516x drivers with SPI interface have a few more features, which can be used for motor current setting via software or sensorless homing when the driver is connected via SPI to the … ... there two more things we need to enable and those are the automatic current tuning and the sensorless homing… Sensorless homing … 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. 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). Ok, now that you know what can happen, let’s try it out. 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. 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. Will these settings overheat the driver? * a lower STALL_VALUE will make it more sensitive. privacy statement. The driver_SGT value describes the threshhold when the driver reports a stall. Are you sure you're not hitting #10629 (comment) ? Attention!! * A higher STALL_VALUE will make the reading less sensitive and. The motor only locks the shaft and does not turn to either side. Update the port and bit position in the ISR as well. You can now proceed with the next axis of your printer. If your axis did not stop (third outcome), the stepper driver was not able to detect the stall, because the load on the motor still seemed reasonable to the driver. Right. Have a look at the datasheet of your specific TMC to avoid mistakes. And it is not surprising, since they … We’ll occasionally send you account related emails. The problem arises with "stallguard". The TMC2130 and TMC5160 have both a diag0_pin and diag1_pin in most known hardware the diag1_pin is appropriate. 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 … See my demo video with the RAMPS - I'm only using one TMC2130 on that board, on X. 0 1023 979 Sign in Let’s try the first sensorless homing now. 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! in front of the pin name. * M914 X/Y/Z to live tune the setting */ #define SENSORLESS_HOMING // TMC2130 only pins_RAMPS.h. I have the latest version of Marlin 1.1.8. 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 … This guide covers the setup of sensorless homing for the X axis of your (cartesian) printer. : understand that this will not work with a stock cr-10, cr-10s, cr-10s4/5 etc. Marlin). Strange, because my example does not work. Further, sensorless homing might not be accurate enough for you printer. Question. Skew correction: Adjustments for axes not perfectly square. I'm about to change my set for a MKS Rumba + .. 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. 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. In this guide we’ll be using a TMC2130. 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 … Steppers work fine under Marlin, direction and all. 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). Run my steppers tmc2130 sensorless homing STALL_VALUE 1: https: //en.aliexpress.com/item/4X-MKS-TMC2130-V1-1-To-Stepstick-Stepper-Motor-Driver-de-Fun-o-SPI-with-Dissipador/32850172695.html? spm=, http: //marlinfw.org/docs/hardware/tmc_drivers.html physical....
