tmc2130 sensorless homing

I left my Hybrid Threshold enabled too .. At speed above 100mm, I can see it working when I'm printing. Everything works great, Stealthchop, SpreadCycle, Interpolation .. Sorry about the code not parsing, I don't know why it only worked on the last section. The engine just makes noise, it does not spin anywhere, even though I type "+" in Terminal. Attention!! But Sensorless Homing can not enable .. But either no luck. Further, you need a pull-up resistor on the connection. There you can also find more details on limitations of this setup. privacy statement. 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. I did not find any instruction on this .. Just saying that Home is always done using spreadCycle .. 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… 0 1023 979 Which is used is determined by which driver pin is connected to the MCU pin. this was designed to completely enclose the xaxis belt drive and is only useful for sensorless homing! * a lower STALL_VALUE will make it more sensitive. 0 1023 979 The motor only locks the shaft and does not turn to either side. The rest sounds ok to me. 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. * You can control the rotation speed with. 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). * You can finetune the reading by changing the STALL_VALUE. Change limit switches pins, … Even if your axis homed correctly, it might be worth to try a few different values for driver_SGT. * A higher STALL_VALUE will make the reading less sensitive and. In order to have stealthchop in standalone enabled if the pins are … To trigger stall detection at a higher load, increase the value of driver_SGT (for example from 0 to 5). @teemuatlut How can I do that? At this point, your axis should be able to home based on the stall detection of the TMC2130. So you should test values like 1, 0 or even -10 or so. .. 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. I suggest you first try to get the example working. Make sure you have sensorless_homing defined not just the values for the sensitivity. 0 1023 979 For Marlin, I have not been able to make it work either. 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… Have a look at the datasheet of your specific TMC to avoid mistakes. The diag1_pin of the TMC2130 is configured as open-collector pin. So not exclusevely but at least for the homeing process. I've had the same issue, by the way. Homing a Z axis by bumping the nozzle into the printing surface might not be a good idea. Your Builds. @rodrigosclosa Have you tried reducing HOMING_FEEDRATE_XY? Already on GitHub? The examples should not work directly without having to change anything? Make sure to fill in the missing values based on your configuration. I'm in a dilemma for setting up the sensorless homing with the TMC2130 drivers, with Ramps 1.4 and Arduino Mega. 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. It will likely not work as intended. 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). I can also change the sensitivity. Sorry for the delay, but I tested the example sketch with the X-axis. Be aware that Klipper needs both DIAG1 pins connected to the MCU. Homing a delta printer sensorless is not advisable due to missing accuracy. Hey everyone, I somehow … 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. Is already any solution that you forgot to post it? 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. i.e. To trigger stall detection at a lighter load, decrease the value of driver_SGT. 0 1023 979 The values can be any interger between -64 and 63. 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 ! 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. More advice: LowRider CNC. Change your homing files' structures. Will these settings overheat the driver? Simple example of the library I have been able to perform, the motor turns from side to side normally. Have a question about this project? 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 … 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 … If I use the stallguard sketch that comes in the library, it all works fine. 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. During homing, you need StallGuard to be enabled no … I could not make the example work properly. Update the port and bit position in the ISR as well. 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. If you go higher than 8 it will be less likely to trigger. You signed in with another tab or window. Which Firmware are you on? 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. 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. Without touching anything else on the firmware configuration, only the sensitivity of the sensorless homing. S CURVE ACCELERATION should be disabled. 0 1023 979 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! I have a SKR 1.3 with TMC2130’s and dual endstops on Y and Z and sensorless homing on all axis. MAX FEED-RATE and ACCELERATIONS should be reduced in order to not to lose steps and avoid layer shifting. To … The stepper driver senses the lost steps and indicates this to the controlling MCU (Klipper) by toggling a pin. Strange, because my example does not work. 0 1023 979 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. Each stepper driver constantly monitors the motor current that it is delivering … On a RAMPS board the Y step pin is D60 which is in PORTF as pin number 6. Finally change pins according to our connection on board. * Plot TMC2130 motor load using the stallGuard value. 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. What does the serial output look like? This information can be used by Klipper as end stop for the axis. Just sayin', because, unfortunately, I couldn't find a solution either. I only changed the Y_CS, the others are unchanged. For very slow speeds (less than 10 RPM) the motor does not generate significant back EMF and the TMC cannot reliably detect motor stalls. Question. Level your X axis by trying to move the Z axis past its physical limit. To use sensorless homing, can not I leave stealthChop enabled? For info, I'm using an Arduino mega 2560 with a ramps 1.5. The symptoms seem similar enough, though if it works on earlier Marlin versions, then it's something different. To make the StallGuard instance work, I copied the part from rotating the Simple Example engine. Does anyone have any light or tips to give me what else can I test? Attached are also my Marlin Configuration and Configuration_adv files bugfix_2.0.x. In none of them can I activate sensorless homing detection. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. But the sensorless homing I can not activate at all! 0 1023 979 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. 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. 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. To enable sensorless homing add a section to configure the TMC stepper driver to your printer.cfg. However, your M122 output looks fine. Lowrider 2, 5'x10', Dual Endstops, Sensorless Homing, SKR 1.3, TMC2130. 0 1023 979 Values have to be in between -64 (most sensitive) and 64 (least sensitive). to your account. Essentially the example works as is. Further, sensorless homing might not be accurate enough for you printer. Congratulations! whats the result ? 0 1023 979 0 1023 979. The Led is lit all the time. The TMC2130 provides an integrated motor driver solution for 3D-Printing, Cameras, Scanners and other automated equipment applications. 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. ] TMC2209 sensorless homing … sensorless homing with the TMC2130 just wanted to activate even sensorless homing text was successfully!
