You signed in with another tab or window. More advice: 0 1023 979 I bought these from china already in the SPI-enabled version in the hope of being easy to configure the sensorless homing. Sensorless homing is simply having no physical sensors mounted on the printer. The output does not change when I put load on the motors. How can this be possible? 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. 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. * M914 X/Y/Z to live tune the setting */ #define SENSORLESS_HOMING // TMC2130 only pins_RAMPS.h. Make sure to fill in the missing values based on your configuration. See THIS image. The … 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. 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.9042322.214.171.124b2b90a7GC1In. Is already any solution that you forgot to post it? M915: TMC_Z_CALIBRATION (Deprecated in Marlin 2.0.) On some TM… * A higher STALL_VALUE will make the reading less sensitive and. Right. * Plot TMC2130 motor load using the stallGuard value. Depends which TMC2130 sou have. 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. However, it works the same with all other axes (that require an end stop). The TMC2130 drivers can tolerate a motor operating current 1.2 A (peak 2 A). @teemuatlut How can I do that? Attention!! The TMC2130 can run in two modes: spreadCycle of … @rodrigosclosa Have you tried reducing HOMING_FEEDRATE_XY? Put the carriage somewhere in the middle of the X axis. On a RAMPS board the Y step pin is D60 which is in PORTF as pin number 6. Change limit switches pins, … Further, sensorless homing might not be accurate enough for you printer. * This will let you control at which load the value will read 0. Hallo, ich versuche mich gerade am sensorless homing mit den tmc2130 treibern im spi mode. Even if I change the STALL_VALUE to 63 the same happens. The homing thresholds seem to be hard-coded (and there is no G-Code command for … 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. It is advised to have a look in the datasheet of your specific TMCs. Sorry about the code not parsing, I don't know why it only worked on the last section. 0 1023 979 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. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. nedwardnz (Ned van Geffen) November 23, 2019, 10:32am #1. On some TMCs like the TMC2209 this value doesn’t exist in this form as the hehavior is different to the TMC2130. If you go higher than 8 it will be less likely to trigger. 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). 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. Some TMC stepper drivers can detect when they bump into something that causes them to stop moving. Any value I put in STALL_VALUE does not affect the behavior at all. * a lower STALL_VALUE will make it more sensitive. : understand that this will not work with a stock cr-10, cr-10s, cr-10s4/5 etc. 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. Make sure you have sensorless_homing defined not just the values for the sensitivity. TMC2130_SG_HOMING is just a flag, so the specific value has no meaning except being different from 0. 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! 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 have now updated the Arduino lib from the TMC2130 to version 2.4.3 and also had the same behavior. It is not sufficient to use only one signal from one of the stepper drivers (as it is possible on e.g. Does it help? * You can control the rotation speed with. Level your X axis by trying to move the Z axis past its physical limit. 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 too am having kinda the same problem with the tmc2130. ... there two more things we need to enable and those are the automatic current tuning and the sensorless homing… It will likely not work as intended. 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 … The driver_SGT value describes the threshhold when the driver reports a stall. 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 … Have a look at the datasheet of your specific TMC to avoid mistakes. 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. to your account. 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. 0 1023 979 1023 = 0b1111111111 and 979 would be close to irun = 0b11111 when vsense = 1. 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. However, your M122 output looks fine. The example assumes X axis is used on a ATMega2560 and RAMPS1.4. Does anyone have any light or tips to give me what else can I test? In order to have stealthchop in standalone enabled if the pins are … There you can also find more details on limitations of this setup. 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… This feature is so sensitive that it can actually take the place of traditional endstops. The driver_SGT value describes the threshhold when the driver reports a stall. They already have the CFG4 and CFG5 with a small resistor, without the SPI resistor and already with the SPI pins welded up. But any value I put in STALL_VALUE does not affect anything. The drivers are labelled as "BIGTREETECH TMC2130 v3.0". 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 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 Firmware are you on? Sensorless homing allows to home an axis without the need for a physical limit switch. Are you sure you're not hitting #10629 (comment) ? 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). in front of the pin name. 2. First try to get the stallGuard example working. I have a SKR 1.3 with TMC2130’s and dual endstops on Y and Z and sensorless homing on all axis. The examples should not work directly without having to change anything? 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. Does anyone know what could be wrong? 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. I'll try the example with the X axis too ... OK, I'll try it. Homing a delta printer sensorless is not advisable due to missing accuracy. I only changed the Y_CS, the others are unchanged. ... /** * TMC2130… 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. 0 1023 979 Taking a closer look at the example output, it would suggest a communication error. If I push the shaft, the connected LED of the DIAG1 does not change, it remains off. I'll try to put just 1 to test. As long as the Diag1 pin is connected to X-min endstop pin on the board (and Y) it should work. Homing a Z axis by bumping the nozzle into the printing surface might not be a good idea. I've had the same issue, by the way. Same here, why did you close it @boelle? Especially spindles (on the Z axis) might generate a lot of force. I tried again to open the StallGuard example, just changed the SPI pins to hit my Y-axis pins on my Ramps (see attached). Just sayin', because, unfortunately, I couldn't find a solution either. We’ll occasionally send you account related emails. Values have to be in between -64 (most sensitive) and 64 (least sensitive). The motor only locks the shaft and does not turn to either side. actually i didn't care about it in the first place but it was important. 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 also does not work for me .. The higher the value, the later it triggers stall detection. MAX FEED-RATE and ACCELERATIONS should be reduced in order to not to lose steps and avoid layer shifting. Each stepper driver constantly monitors the motor current that it is delivering … 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 tested it with Marlin versions 1.1.8, bugfix-1.1.x and bugfix-2.0.x. To trigger stall detection at a higher load, increase the value of driver_SGT (for example from 0 to 5). If you want to add sensor-less homing to your cr-10 and have the tmc2130 … 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 _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. For very slow speeds (less than 10 RPM) the motor does not generate significant back EMF and the TMC cannot reliably detect motor stalls. To use sensorless homing, can not I leave stealthChop enabled? Be aware that Klipper needs both DIAG1 pins connected to the MCU. In this guide we’ll be using a TMC2130. 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 … ... [BUG] TMC2209 Sensorless Homing … The configuration however is simailar to the other TMCs with StallGuard: The above snippet configures a TMC2130 for the stepper on the X axis. Ok, now that you know what can happen, let’s try it out. Change your homing files' structures. 0 1023 979 I bought these for not having been able to enable the sensorless homing in the old as well. I can also change the sensitivity. Interestingly when i set this command : ` # define SENSORLESS_HOMING // TMC2130 only # if ENABLED(SENSORLESS_HOMING) # define X_HOMING_SENSITIVITY-1 # define … 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. By clicking “Sign up for GitHub”, you agree to our terms of service and 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. During homing, you need StallGuard to be enabled no … 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. The symptoms seem similar enough, though if it works on earlier Marlin versions, then it's something different. I did not find any instruction on this .. Just saying that Home is always done using spreadCycle .. The problem arises with "stallguard". 0 1023 979. whats the result ? 0 1023 979 The value is not reflected in the M112 command nor the initial echo out when i connect to the board. 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. I havent tried stall detection yet though. Tks for the sketch. Congratulations! 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 examples also don't work. Make sure to fill in the missing values based on your configuration. @teemuatlut if I hold the spindle the diag pin goes high and the serial out gives me the same results. If I use the stallguard sketch that comes in the library, it all works fine. Issue was not solved and the topic is closed ! The stepper driver senses the lost steps and indicates this to the controlling MCU (Klipper) by toggling a pin. In other words, everything read from the driver would be read as HIGH. Question. * You can finetune the reading by changing the STALL_VALUE. 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. I'm in a dilemma for setting up the sensorless homing with the TMC2130 drivers, with Ramps 1.4 and Arduino Mega. The text was updated successfully, but these errors were encountered: Hi, I run my steppers at STALL_VALUE 1.
