First, I'm trying to move the X-Axis to the right from the printer's Motion - Move Axis - Move X menu. But this wastes zero time since it's all finished long before the bed reaches final temp, let alone any heatsoaking (which I rarely bother doing. A good starting point for the homing speed is for the stepper motor to make a full rotation every two seconds. 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). I opted to keep an end-stop switch for the Z-Axis so I can easily move the minimum height of the carriage. 3 32-bit main board BigTreeTech TFT35 Touch Screen TMC2209 Drivers - UART Mode Marlin 2. The stepper driver senses the lost steps and indicates this to the controlling MCU (Klipper) by toggling a pin. SensorLess Homing goes wrong I need your help for the homing.

For example: Jul 27, 2024 · Now, start increasing your SGTHRS value until sensorless homing no longer works. Start with X. You can use the motors for any axis arrangement like XYYZ, etc. You'll need to ensure the board jumpers are configured for UART mode and to connect the DIAG pins on X and Y to the endstop positions, and that the firmware is also configured to operate them in UART mode, as well as enabling #define SENSORLESS_HOMING and setting the stall sensitivity (in Configuration_adv. I've tried to switch motor and driver with no luck. BigTreeTech omitted those on the V1. 5b1 related thing). g (adjusting any X moves to Y) When homing, only the X-Axis properly moves and homes without an endstop switch. Despite extensive tuning of driver_SGTHRS and motor settings, the Z-axis triggers the endstop prematurely. 3, Bigtreetech 2209 V1. Yes, it's going to the right. toolhead. Only a total power off can change this. The relevant changes that need to be made to enable the options in the firmware are: Configuration. Adjust accordingly.

Now Easiest solution is use Endstop switch on Z axis. 3, the SKR 2, and other boards that have provision for 2209s and sensorless homing, there are links to disconnect the DIAG pins from the rest of the endstop switch circuitry. Sensorless homing makes use of the stallguard feature built into the TMC2209 stepper drivers plugged into the Manta M8P for the A & B motors that drive the toolhead on X & Y. The bed does not stop moving along the y axis when homing. Maybe defining sensorless homing on Y axis and not declaring driver_SGTHRS for that axis is screwing it up ? Like mentioned before, try to follow the documentation and/or a guide and I would suggest to backup your printer. Some places I’m reading . ) Apr 25, 2021 · All axis move normally but sensorless homing only works on the Y axis and LCD reports "TMC Connection Error".
