tmc2130 sensorless homing

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. 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 … Already on GitHub? Sorry for the delay, but I tested the example sketch with the X-axis. I have a SKR 1.3 with TMC2130’s and dual endstops on Y and Z and sensorless homing on all axis. Values have to be in between -64 (most sensitive) and 64 (least sensitive). This feature is so sensitive that it can actually take the place of traditional endstops. 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. I've changed the SPI pin settings for my setup. 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. 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. 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. Put the carriage somewhere in the middle of the X axis. Let’s try the first sensorless homing now. 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). You signed in with another tab or window. 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). The stepper driver senses the lost steps and indicates this to the controlling MCU (Klipper) by toggling a pin. See my demo video with the RAMPS - I'm only using one TMC2130 on that board, on X. M915: TMC_Z_CALIBRATION (Deprecated in Marlin 2.0.) I suppose it would be possible that your particular motors need a negative threshold value and that somehow is bugged. It is advised to have a look in the datasheet of your specific TMCs. 0 1023 979 But do you have any tips on what could be wrong and I can not enable the Sensorless homing in Marlin? ... there two more things we need to enable and those are the automatic current tuning and the sensorless homing… 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. … It will likely not work as intended. Homing a delta printer sensorless is not advisable due to missing accuracy. 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 ! The TMC2130 drivers can tolerate a motor operating current 1.2 A (peak 2 A). 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. 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. The engine just makes noise, it does not spin anywhere, even though I type "+" in Terminal. See THIS image. For Marlin, I have not been able to make it work either. As long as the Diag1 pin is connected to X-min endstop pin on the board (and Y) it should work. The motor only locks the shaft and does not turn to either side. 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! 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. I'll try to put just 1 to test. Skew correction: Adjustments for axes not perfectly square. Issue was not solved and the topic is closed ! ... /** * TMC2130… Sensorless Homeing requires the the TMC2130 to be in spreadcycle Mode. The TMC2130 provides an integrated motor driver solution for 3D-Printing, Cameras, Scanners and other automated equipment applications. Make sure to fill in the missing values based on your configuration. Sensorless homing: Configuring tmc2130 sensorless homing. On some TMCs like the TMC2209 this value doesn’t exist in this form as the hehavior is different to the TMC2130. More advice: Have a look at the datasheet of your specific TMC to avoid mistakes. We’ll occasionally send you account related emails. Does it help? Make sure to fill in the missing values based on your configuration. * Plot TMC2130 motor load using the stallGuard value. 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. S CURVE ACCELERATION should be disabled. And it is not surprising, since they … 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. Update the port and bit position in the ISR as well. 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. Sensorless homing allows to home an axis without the need for a physical limit switch. On a RAMPS board the Y step pin is D60 which is in PORTF as pin number 6. The examples also don't work. However, your M122 output looks fine. … Attached are also my Marlin Configuration and Configuration_adv files bugfix_2.0.x. This guide covers the setup of sensorless homing for the X axis of your (cartesian) printer. Where do I need to change the PORTF and the pin position? @rodrigosclosa Have you tried reducing HOMING_FEEDRATE_XY? Not sure if this would be the right place, but I am currently looking at upgrading the tmc2208 drivers I am currently using with a SKR 1.3 board and am trying to decide between the TMC2209 and TMC2130 to support sensorless homing… Could you provide an example of that? 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 … Congratulations! MAX FEED-RATE and ACCELERATIONS should be reduced in order to not to lose steps and avoid layer shifting. Instead, the TMC2130 can be used as a sensor. I too am having kinda the same problem with the tmc2130. Sensorless homing … 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. In stealthchop sensoless homing won't work at all. To … Be aware that Klipper needs both DIAG1 pins connected to the MCU. 0 1023 979 The driver_SGT value describes the threshhold when the driver reports a stall. However, it works the same with all other axes (that require an end stop). They already have the CFG4 and CFG5 with a small resistor, without the SPI resistor and already with the SPI pins welded up. To enable sensorless homing add a section to configure the TMC stepper driver to your printer.cfg. Interestingly when i set this command : ` # define SENSORLESS_HOMING // TMC2130 only # if ENABLED(SENSORLESS_HOMING) # define X_HOMING_SENSITIVITY-1 # define … What does the serial output look like? Attention!! First try to get the stallGuard example working. There you can also find more details on limitations of this setup. But the sensorless homing I can not activate at all! Some TMC stepper drivers can detect when they bump into something that causes them to stop moving. whats the result ? TMC2130_SG_HOMING is just a flag, so the specific value has no meaning except being different from 0. 0 1023 979 The example uses direct register manipulation. 0 1023 979 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. Start ... in front of the pin name. i.e. Sign in Does anyone have any light or tips to give me what else can I test? For example, the following configures a single TMC2130 on the X axis, it's CS tied to pin 37: #define TMC2130_X_CS_PIN 37 #define TMC2130_Y_CS_PIN -1 #define TMC2130… In order to have stealthchop in standalone enabled if the pins are … So not exclusevely but at least for the homeing process. Hallo, ich versuche mich gerade am sensorless homing mit den tmc2130 treibern im spi mode. Will these settings overheat the driver? privacy statement. Lowrider 2, 5'x10', Dual Endstops, Sensorless Homing, SKR 1.3, TMC2130. I left my Hybrid Threshold enabled too .. At speed above 100mm, I can see it working when I'm printing. If you want to add sensor-less homing to your cr-10 and have the tmc2130 … It also does not work for me .. I tested it with Marlin versions 1.1.8, bugfix-1.1.x and bugfix-2.0.x. * You can finetune the reading by changing the STALL_VALUE. Marlin). 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 … To enable sensorless homing add a section to configure the TMC stepper driver to your printer.cfg. If I push the shaft, the connected LED of the DIAG1 does not change, it remains off. 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. By clicking “Sign up for GitHub”, you agree to our terms of service and @teemuatlut There are many other options to configure on a TMC2130, make sure to take a look at config reference for all the available options. Even if your axis homed correctly, it might be worth to try a few different values for driver_SGT. I have now updated the Arduino lib from the TMC2130 to version 2.4.3 and also had the same behavior. Right. Change limit switches pins, … 0 1023 979 Now that the stepper driver is configured, let’s make sure that Klipper can communicate with the TMC2130 by sending the following extended G-Code command to the printer: This command tells Klipper to read a few registers via SPI from the TMC2130. * A higher STALL_VALUE will make the reading less sensitive and. * a lower STALL_VALUE will make it more sensitive. To trigger stall detection at a lighter load, decrease the value of driver_SGT. I've had the same issue, by the way. 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). I can also change the sensitivity. So you should test values like 1, 0 or even -10 or so. The rest sounds ok to me. nedwardnz (Ned van Geffen) November 23, 2019, 10:32am #1. 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). Further, you need a pull-up resistor on the connection. @teemuatlut How can I do that? Have a question about this project? Use this … LowRider CNC. The drivers work perfectly with Marlin, I'm printing with them. In Marlin the switch to spreadcycle for Homing … Steppers work fine under Marlin, direction and all. 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. I just wanted to activate even Sensorless Homing ... Did you change anything in the example before uploading? this was designed to completely enclose the xaxis belt drive and is only useful for sensorless homing! The drivers are labelled as "BIGTREETECH TMC2130 v3.0". At this point, your axis should be able to home based on the stall detection of the TMC2130. 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. For info, I'm using an Arduino mega 2560 with a ramps 1.5. I bought these for not having been able to enable the sensorless homing in the old as well. 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. 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. But any value I put in STALL_VALUE does not affect anything. @lucassing i finally solved my own problem by soldering small tiny jumpers to enable sensor-less homing. @comps I suggest you first try to get the example working. Does anyone know what could be wrong? 1023 = 0b1111111111 and 979 would be close to irun = 0b11111 when vsense = 1. Sorry about the code not parsing, I don't know why it only worked on the last section. Each stepper driver constantly monitors the motor current that it is delivering … TMC2130_TCOOLTHRS sets the speed above which StallGuard (= your homing signal) will be enabled (BUT: high TCOOLTHRS value = low speed). 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 values can be any interger between -64 and 63. Will the TMC2130 … In this guide we’ll be using a TMC2130. 0 1023 979 The examples should not work directly without having to change anything? The symptoms seem similar enough, though if it works on earlier Marlin versions, then it's something different. Not even if I type the + in the terminal or -, if I type 0 it releases the axis and with 1 it locks again. Strange, because my example does not work. actually i didn't care about it in the first place but it was important. The text was updated successfully, but these errors were encountered: Hi, I run my steppers at STALL_VALUE 1. 0 1023 979 I could not make the example work properly. Essentially the example works as is. Which Firmware are you on? I didn't need to do anything but I did change STALL_VALUE to 10 so that I could see coolStep working properly. During homing, you need StallGuard to be enabled no … I only changed the Y_CS, the others are unchanged. They are already standard for use with SPI. If Watterott you have to close the SPI solder Bridge in order have them in standalone. I followed this guide too, but without success: http://marlinfw.org/docs/hardware/tmc_drivers.html. The Led is lit all the time. But I had to define the spi pins for it to work. G-Codes: Information on commands supported by Klipper. 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. if I hold the spindle the diag pin goes high and the serial out gives me the same results. Just sayin', because, unfortunately, I couldn't find a solution either. I'll try the example with the X axis too ... OK, I'll try it. Without touching anything else on the firmware configuration, only the sensitivity of the sensorless homing. 0 1023 979. 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. Ok, now that you know what can happen, let’s try it out. The way you "enable" a driver in Configuration.h is by adding a line for it's CS pin. Developer Documentation. Even if I change the STALL_VALUE to 63 the same happens. The device has an integrated microstepping indexer, the sensorless stall detection technology StallGuard2™, the sensorless … The TMC2130 and TMC5160 have both a diag0_pin and diag1_pin in most known hardware the diag1_pin is appropriate. But the TMC drivers are working perfectly on the printer, I already printed several parts with them .. 2. ... [BUG] TMC2209 Sensorless Homing … Sensorless homing works best at medium motor speeds. In none of them can I activate sensorless homing detection. Instead, the carriage on the axis is moved into the mechanical limit making the stepper motor lose steps. The configuration however is simailar to the other TMCs with StallGuard: The above snippet configures a TMC2130 for the stepper on the X axis. Also I noticed that you said it would go the wrong way with negative values, that to me points to an issue where if you use the diag pins to the endstops but don’t declare sensorless homing in the firmware it will sometimes do that on homing moves. The driver_SGT value describes the threshhold when the driver reports a stall. * and the stall flag will be triggered. 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. The homing thresholds seem to be hard-coded (and there is no G-Code command for … How can this be possible? 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 … * M914 X/Y/Z to live tune the setting */ #define SENSORLESS_HOMING // TMC2130 only pins_RAMPS.h. 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. 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). Which is used is determined by which driver pin is connected to the MCU pin. In other words, everything read from the driver would be read as HIGH. This issue has been automatically locked since there has not been any recent activity after it was closed. I just tried it with a FYSETC v1.1 driver and the example does work for sure. * You can control the rotation speed with. Level your X axis by trying to move the Z axis past its physical limit. Finally change pins according to our connection on board. 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). Everything works great, Stealthchop, SpreadCycle, Interpolation .. Is already any solution that you forgot to post it? 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. Taking a closer look at the example output, it would suggest a communication error. 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. This will also set pin DIAG1 high. You should configure and tune it for one axis at a time. 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. I havent tried stall detection yet though. Homing a Z axis by bumping the nozzle into the printing surface might not be a good idea. 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. I bought these from china already in the SPI-enabled version in the hope of being easy to configure the sensorless homing. For very slow speeds (less than 10 RPM) the motor does not generate significant back EMF and the TMC cannot reliably detect motor stalls. Further, sensorless homing might not be accurate enough for you printer. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. It is not sufficient to use only one signal from one of the stepper drivers (as it is possible on e.g. Are you sure you're not hitting #10629 (comment) ? I've tried to tune up rising from 0 to +63 and from 0 to -64. The diag1_pin of the TMC2130 is configured as open-collector pin. 0 1023 979 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 … .. Successfully merging a pull request may close this issue. Same here, why did you close it @boelle? Your Builds. Depends which TMC2130 sou have. 0 1023 979 The output does not change when I put load on the motors. The configuration however is simailar to the other TMCs with StallGuard: The above snippet configures a TMC2130 for the stepper on the X axis. In this guide we’ll be using a TMC2130. 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 value is not reflected in the M112 command nor the initial echo out when i connect to the board. Make sure you have sensorless_homing defined not just the values for the sensitivity. Simple example of the library I have been able to perform, the motor turns from side to side normally. 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. I'm in a dilemma for setting up the sensorless homing with the TMC2130 drivers, with Ramps 1.4 and Arduino Mega. : understand that this will not work with a stock cr-10, cr-10s, cr-10s4/5 etc. I'm about to change my set for a MKS Rumba + .. But Sensorless Homing can not enable .. ATTENTION: This guide only mentions the mandatory parameters and the ones needed to set up sensorless homing. I just added a pin to DIAG1 (which is the pad closest to the potentiometer). Any value I put in STALL_VALUE does not affect the behavior at all. The higher the value, the later it triggers stall detection. If I use the stallguard sketch that comes in the library, it all works fine. Instance work, I have now updated the Arduino lib from the driver for sensorless homing Marlin. Slow.. How it could affect the behavior at all problems with SPI. Diag1_Pin of the X axis threshold value and that somehow is bugged homed correctly, it on. Are labelled as `` BIGTREETECH TMC2130 v3.0 '' them can I activate sensorless homing none them. Configuration I have now updated the Arduino lib from the TMC2130 can run in two modes spreadCycle. Related emails goes HIGH and the community, you agree to our connection on board signal one.
