V40 sets the speed at which the driver switches over to spreadcycle. Hello, my name is Daniel, welcome to the CrossLink channel. g. Sensorless Homing¶ Sensorless homing allows to home an axis without the need for a physical limit switch. Setting Up and Calibrating Sensorless XY Homing . Jul 27, 2024 · Now, start increasing your SGTHRS value until sensorless homing no longer works. Do you have a wiring diagram or an image of how your wiring is done? I'm curious how you connected the UART to multiple stepper drivers. Feb 18, 2025 · When using the TMC2130 / TMC2209 / TMC2660 / TMC5160 drivers, the StallGuard feature makes it possible to set up sensorless homing on the X and Y axes for CoreXY machines. Jan 19, 2023 · Potential Ender 3 stepper drivers & sensorless homing support status. It works sometimes, but not consistently. Apr 23, 2023 · I’m attempting sensorless homing on my MP3DPv4 for thr Z axis. Jun 30, 2020 · And well, with all this you should already have your TMC2209 Watterott drivers operating in UART mode and without any type of limit switch (Sensorless). Drivers TMC2209 ERYONE V3. Nov 17, 2023 · Describe your issue: Sensorless homing isn’t working on the octopus, i’ve placed jumpers on all the pins next to the endstop sockets, but when homing either X or Y, it simply crashes into the frame and keeps grinding. Mar 30, 2023 · How did you come up with your sensorless homing values? I think your problem is that the threshold values (driver_sgthrs) are so sensitive that the subsequent homing operating gets a false sense and causes the toolhead to move to the right, causing the head crash and buzzing. g is to add the following to each M569 command where sensorless homing is to be used. Sensorless homing requires drivers like the TMC2209 and a compatible mainboard which can relay the sensing of the stall back to the marlin firmware. M915 X Y R0 F0. The Klipper project has a page with documentation and recommendations on getting it working. The final value for your X axis SGTHRS value is the average of the two (( upper limit - 'lower limit`) / 2). 40 #50 homing_retract_dist: 0 homing_positive_dir: true [tmc2209 stepper Official support for TMC2209, TMC2240, and TMC5160. Include the following M915 command in config. D3 V40 D3 sets the driver into stealthchop mode. Unfortunately, even in the case of an Ender 3 that has the TMC2209 drivers, utilizing sensorless homing will not be possible, as the stock mainboard of the Ender 3 has the stepper drivers connected in standalone mode, and the TMC2209 requires UART connection for sensorless homing to be available. It seems to be worst when it’s already at the bottom of travel (ie: already homed. Andrea Favero's latest project showcases sensorless homing and centring of a stepper motor using a Raspberry Pi Pico and a TMC2209 driver. . 0. A simple code using the TMCStepper and AccelStepper library to test the sensor-less homing feature of the TMC2209 stepper driver - KushagraK7/TMC2209_sensorless_homing_test Sensorless Homing¶ Sensorless homing allows to home an axis without the need for a physical limit switch. Support for TMC2130, TMC2208 and TMC2660 may work, but is completely untested. 3 mainboard with TMC2209 stepper drivers and sensorless homing. 1 with 2209 drivers. This is where the main setup of sensorless homing takes place. For example, M574 X1 S3 sets the X endstop to sensorless homing at the axes low end, while M574 Y2 S3 sets Y endstops to sensorless homing at the axes high end. This sets up the last main command needed I have been struggling for quite some time already to enable sensorless homing on an Arduino using TMC 2209 stepper drivers. On the SKR this is done through the two additional DIAG pins the TMC2209 step sticks and the 2 addtional pins on the SKR board. The stepper driver senses the lost steps and indicates this to the controlling MCU (Klipper) by toggling a pin. Instead, the carriage on the axis is moved into the mechanical limit making the stepper motor lose steps. ) Some of the RRF notes on it: apparently it works better at higher speeds. When using the TMC2130 / TMC2209 / TMC2660 / TMC5160 drivers, the StallGuard feature makes it possible to set up sensorless homing on the X and Y axes for CoreXY machines. Feb 25, 2025 · This technique, though available for years in stepper motor drivers like the Trinamic TMC2209, remains relatively underutilised due to its complexity and sensitivity to speed variations. Finally, in this list of TMC2209 Drivers from the different manufacturers I know, we would find the driver belonging to the Eryone company. This is your upper limit.

Sensorless homing can work at either end of each axis, ie the low or high end. Sensorless homing with autotuning enabled is known to work on TMC2209, TMC2240 and TMC5160, provided you home fast enough (homing_speed should be numerically greater than rotation_distance for those axes using sensorless homing). This writeup covers how to set up sensorless homing on an Octopus 1. com/playlist?list Configuring sensorless homing; Maintenance Guide; Voron History; Community Documentation.
