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. Taking a closer look at the example output, it would suggest a communication error. To enable sensorless homing add a section to configure the TMC stepper driver to your printer.cfg. Will these settings overheat the driver? 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 … It is advised to have a look in the datasheet of your specific TMCs. 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. nedwardnz (Ned van Geffen) November 23, 2019, 10:32am #1. You signed in with another tab or window. The homing thresholds seem to be hard-coded (and there is no G-Code command for … In this guide we’ll be using a TMC2130. 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. 0 1023 979 I have now updated the Arduino lib from the TMC2130 to version 2.4.3 and also had the same behavior. Even if your axis homed correctly, it might be worth to try a few different values for driver_SGT. In order to have stealthchop in standalone enabled if the pins are … Further, sensorless homing might not be accurate enough for you printer. The TMC2130 provides an integrated motor driver solution for 3D-Printing, Cameras, Scanners and other automated equipment applications. See my demo video with the RAMPS - I'm only using one TMC2130 on that board, on X. @comps The diag1_pin of the TMC2130 is configured as open-collector pin. They are already standard for use with SPI. Will the TMC2130 … Instead, the TMC2130 can be used as a sensor. Sensorless homing allows to home an axis without the need for a physical limit switch. 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. Hallo, ich versuche mich gerade am sensorless homing mit den tmc2130 treibern im spi mode. Your Builds. 0 1023 979. 0 1023 979 And it is not surprising, since they … The stepper driver senses the lost steps and indicates this to the controlling MCU (Klipper) by toggling a pin. Be aware that Klipper needs both DIAG1 pins connected to the MCU. How can this be possible? 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. Attention!! Attached are also my Marlin Configuration and Configuration_adv files bugfix_2.0.x. If you think that it bumps too hard into the mechanical limit, try to decrease the value by 1 or 2. Strange, because my example does not work. Interestingly when i set this command : ` # define SENSORLESS_HOMING // TMC2130 only # if ENABLED(SENSORLESS_HOMING) # define X_HOMING_SENSITIVITY-1 # define … For info, I'm using an Arduino mega 2560 with a ramps 1.5. This will also set pin DIAG1 high. * You can finetune the reading by changing the STALL_VALUE. @rodrigosclosa Have you tried reducing HOMING_FEEDRATE_XY? Which is used is determined by which driver pin is connected to the MCU pin. I have the latest version of Marlin 1.1.8. This issue has been automatically locked since there has not been any recent activity after it was closed. The examples also don't work. They already have the CFG4 and CFG5 with a small resistor, without the SPI resistor and already with the SPI pins welded up. The device has an integrated microstepping indexer, the sensorless stall detection technology StallGuard2™, the sensorless … On some TMCs like the TMC2209 this value doesn’t exist in this form as the hehavior is different to the TMC2130. 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. To make the StallGuard instance work, I copied the part from rotating the Simple Example engine. 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 … This guide covers the setup of sensorless homing for the X axis of your (cartesian) printer. 0 1023 979 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). I'll try to put just 1 to test. Some TMC stepper drivers can detect when they bump into something that causes them to stop moving. You can now proceed with the next axis of your printer. In stealthchop sensoless homing won't work at all. @mbuc My HOMING_FEEDRATE_XY was 3000, very slow.. How it could affect the working of sensorless homing? But do you have any tips on what could be wrong and I can not enable the Sensorless homing in Marlin? Even if I change the STALL_VALUE to 63 the same happens. 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). 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 … This information can be used by Klipper as end stop for the axis. The problem arises with "stallguard". But the TMC drivers are working perfectly on the printer, I already printed several parts with them .. It also does not work for me .. 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. I suggest you first try to get the example working. Skew correction: Adjustments for axes not perfectly square. Which Firmware are you on? G-Codes: Information on commands supported by Klipper. To enable sensorless homing add a section to configure the TMC stepper driver to your printer.cfg. I just added a pin to DIAG1 (which is the pad closest to the potentiometer). 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. Any value I put in STALL_VALUE does not affect the behavior at all. I havent tried stall detection yet though. Lowrider 2, 5'x10', Dual Endstops, Sensorless Homing, SKR 1.3, TMC2130. 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. I tested it with Marlin versions 1.1.8, bugfix-1.1.x and bugfix-2.0.x. But I had to define the spi pins for it to work. The example assumes X axis is used on a ATMega2560 and RAMPS1.4. The engine just makes noise, it does not spin anywhere, even though I type "+" in Terminal. The way you "enable" a driver in Configuration.h is by adding a line for it's CS pin. Without touching anything else on the firmware configuration, only the sensitivity of the sensorless homing. Does anyone know what could be wrong? * You can control the rotation speed with. During homing, you need StallGuard to be enabled no … this was designed to completely enclose the xaxis belt drive and is only useful for sensorless homing! Level your X axis by trying to move the Z axis past its physical limit. At this point, your axis should be able to home based on the stall detection of the TMC2130. 0 1023 979 Instead, the carriage on the axis is moved into the mechanical limit making the stepper motor lose steps. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. 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 higher the value, the later it triggers stall detection. Not even if I type the + in the terminal or -, if I type 0 it releases the axis and with 1 it locks again. The driver_SGT value describes the threshhold when the driver reports a stall. 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. The text was updated successfully, but these errors were encountered: Hi, I run my steppers at STALL_VALUE 1. Marlin). 0 1023 979 LowRider CNC. Sorry about the code not parsing, I don't know why it only worked on the last section. For very slow speeds (less than 10 RPM) the motor does not generate significant back EMF and the TMC cannot reliably detect motor stalls. if I hold the spindle the diag pin goes high and the serial out gives me the same results. I've changed the SPI pin settings for my setup. i have exactly the same problem and dont know what to do. First try to get the stallGuard example working. 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. If I use the stallguard sketch that comes in the library, it all works fine. I did not find any instruction on this .. Just saying that Home is always done using spreadCycle .. The drivers work perfectly with Marlin, I'm printing with them. Start ... The TMC2130 and TMC5160 have both a diag0_pin and diag1_pin in most known hardware the diag1_pin is appropriate. I have a SKR 1.3 with TMC2130’s and dual endstops on Y and Z and sensorless homing on all axis. For Marlin, I have not been able to make it work either. So not exclusevely but at least for the homeing process. Sensorless Homeing requires the the TMC2130 to be in spreadcycle Mode. 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… If you go higher than 8 it will be less likely to trigger. I followed this guide too, but without success: http://marlinfw.org/docs/hardware/tmc_drivers.html. 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 … 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). Finally change pins according to our connection on board. 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. 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. Essentially the example works as is. Homing a delta printer sensorless is not advisable due to missing accuracy. Does it help? 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. It is not sufficient to use only one signal from one of the stepper drivers (as it is possible on e.g. 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. I'm about to change my set for a MKS Rumba + .. ... /** * TMC2130… The example uses direct register manipulation. 2. Where do I need to change the PORTF and the pin position? 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! To trigger stall detection at a lighter load, decrease the value of driver_SGT. I've had the same issue, by the way. Let’s try the first sensorless homing now. Use this … In this guide we’ll be using a TMC2130. Sorry for the delay, but I tested the example sketch with the X-axis. 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. * and the stall flag will be triggered. I too am having kinda the same problem with the tmc2130. .. Issue was not solved and the topic is closed ! Sign in Update the port and bit position in the ISR as well. I can also change the sensitivity. The rest sounds ok to me. Will I have any of these problems with the configuration I have set above? Already on GitHub? But Sensorless Homing can not enable .. But either no luck. Does anyone have any light or tips to give me what else can I test? I've tried to tune up rising from 0 to +63 and from 0 to -64. To trigger stall detection at a higher load, increase the value of driver_SGT (for example from 0 to 5). I'll try the example with the X axis too ... OK, I'll try it. 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. In Marlin the switch to spreadcycle for Homing … The examples should not work directly without having to change anything? If I push the shaft, the connected LED of the DIAG1 does not change, it remains off. Values have to be in between -64 (most sensitive) and 64 (least sensitive). 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. The symptoms seem similar enough, though if it works on earlier Marlin versions, then it's something different. The output does not change when I put load on the motors. Ok, now that you know what can happen, let’s try it out. i.e. The Led is lit all the time. The TMC2130 drivers can tolerate a motor operating current 1.2 A (peak 2 A). Question. Developer Documentation. 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. More advice: The configuration however is simailar to the other TMCs with StallGuard: The above snippet configures a TMC2130 for the stepper on the X axis. ATTENTION: This guide only mentions the mandatory parameters and the ones needed to set up sensorless homing. 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. 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. 0 1023 979 TMC2130_SG_HOMING is just a flag, so the specific value has no meaning except being different from 0. ... [BUG] TMC2209 Sensorless Homing … 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. Steppers work fine under Marlin, direction and all. So you should test values like 1, 0 or even -10 or so. Sensorless homing works best at medium motor speeds. 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. Make sure to fill in the missing values based on your configuration. MAX FEED-RATE and ACCELERATIONS should be reduced in order to not to lose steps and avoid layer shifting. * a lower STALL_VALUE will make it more sensitive. To use sensorless homing, can not I leave stealthChop enabled? I just wanted to activate even Sensorless Homing ... Did you change anything in the example before uploading? I suppose it would be possible that your particular motors need a negative threshold value and that somehow is bugged. Could you provide an example of that? However, your M122 output looks fine. On some TM… I only changed the Y_CS, the others are unchanged. 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). Just sayin', because, unfortunately, I couldn't find a solution either. On a RAMPS board the Y step pin is D60 which is in PORTF as pin number 6. The values can be any interger between -64 and 63. But the sensorless homing I can not activate at all! * Plot TMC2130 motor load using the stallGuard value. Everything works great, Stealthchop, SpreadCycle, Interpolation .. Homing a Z axis by bumping the nozzle into the printing surface might not be a good idea. privacy statement. 0 1023 979 We’ll occasionally send you account related emails. Simple example of the library I have been able to perform, the motor turns from side to side normally. I bought these for not having been able to enable the sensorless homing in the old as well. If Watterott you have to close the SPI solder Bridge in order have them in standalone. 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. @teemuatlut Sensorless homing … 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… I left my Hybrid Threshold enabled too .. At speed above 100mm, I can see it working when I'm printing. … But any value I put in STALL_VALUE does not affect anything. Right. The driver_SGT value describes the threshhold when the driver reports a stall. 1023 = 0b1111111111 and 979 would be close to irun = 0b11111 when vsense = 1. The … There you can also find more details on limitations of this setup. Especially spindles (on the Z axis) might generate a lot of force. To … In other words, everything read from the driver would be read as HIGH. ... there two more things we need to enable and those are the automatic current tuning and the sensorless homing… … 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. Is already any solution that you forgot to post it? If you want to add sensor-less homing to your cr-10 and have the tmc2130 … to your account. Make sure you have sensorless_homing defined not just the values for the sensitivity. What does the serial output look like? 0 1023 979 I tried again to open the StallGuard example, just changed the SPI pins to hit my Y-axis pins on my Ramps (see attached). 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. Further, you need a pull-up resistor on the connection. Congratulations! Sensorless homing is simply having no physical sensors mounted on the printer. @teemuatlut How can I do that? Have a look at the datasheet of your specific TMC to avoid mistakes. : understand that this will not work with a stock cr-10, cr-10s, cr-10s4/5 etc. 0 1023 979 Make sure to fill in the missing values based on your configuration. Hey everyone, I somehow … 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. The drivers are labelled as "BIGTREETECH TMC2130 v3.0". 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. * A higher STALL_VALUE will make the reading less sensitive and. That supports all you need for tmc drivers and works stable. Depends which TMC2130 sou have. 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 … Tks for the sketch. S CURVE ACCELERATION should be disabled. However, it works the same with all other axes (that require an end stop). Are you sure you're not hitting #10629 (comment) ? The TMC2130 can run in two modes: spreadCycle of … I could not make the example work properly. In none of them can I activate sensorless homing detection. See THIS image. 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 bought my TMC2130 from Watterott which I assume to be a reliable distributor, not selling cheap Chinese clones (or at least somehow denote it). 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. Change your homing files' structures. Change limit switches pins, … M915: TMC_Z_CALIBRATION (Deprecated in Marlin 2.0.) @lucassing i finally solved my own problem by soldering small tiny jumpers to enable sensor-less homing. 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. whats the result ? Values have to be in between -64 (most sensitive) and 64 (least sensitive). Sensorless homing: Configuring tmc2130 sensorless homing. This feature is so sensitive that it can actually take the place of traditional endstops. * M914 X/Y/Z to live tune the setting */ #define SENSORLESS_HOMING // TMC2130 only pins_RAMPS.h.
