TMC2209 wiring for use UART and sensorless homing ?
Hello, I hope you can help me. Which pins from the TMC2209 v1.3 need to be connected to which pin on the board? I would like to use the drivers in uart mode. And use sensorless homing.
Thanks, I set this jumper. But the sensorless homing doesn't work. Do I have to connect a cable from the TMC2209 to one of the pins of "5" Sensorless Homing (on the picture) connector?
here my printer.cfg:

You need a jumper on the Diags header, then you set the diag_pin to the jumpered endstop pin.
I set the jumper on the board under the driver, set the jumper on diag, set it in config still wont trigger :(

Assuming you put a jumper on that diags header in the lower right. First, I would remove the pullup (^) on the diag pin, diag_pin: PA14. Second I would increase the driver_SGTHRS value to 130 until you have a successful trigger.
Any reason you are running a high microstepping? 16 should be adequate with less torque loss.
The motors won't even move now, removing the pull up resistor as u said just make it auto trigger endstop, inverting diag with ! also makes it auto trigger engstop, currently if I home nothing happens yet it says i homed and i can move as per normal with the arrows yet I never actually homed so position is wrong

@gaby64: Where did you get the pinout document? I try to find some documents like this but without succsess.

Has anyone managed to resolve? I tested with the settings you mentioned and it didn't work for me. I am using TMC2226. And I can't get the Z-axis endstop to work. I'm using the structure of an Ender3 and the Z-axis goes down until it locks on the table.
I have sensorless homing working on 4 steppers. Here is my config:

Thank you so much, reading your code I was able to find out where I was going wrong. My printer is live again
Could someone send the sensorless configuration? did you have to put any jumpers on the board?
leia os comentários anteriores! está tudo aí
From what I understand the configuration would be... ...but don't works...

[tmc2209 stepper_y] uart_pin: PE3 diag_pin: PA15 driver_SGTHRS: 0 run_current: 0.8 hold_current: 0.5 interpolate: True
Did you set the jumpers as indicated in previous comments?
What do you mean by it does not work? What does it do?
driver_SGTHRS: 0 This value would never trigger, it will crash.
sorry, i'm used this (sgthrs 0 and 255) config before to test, but now is 130....
Thanks so much. never considered X- and Y- were the pins I was trying to find
Same problem. My setup looks like it should work, but doesn't. Extremely frustrating. I guess I need to start switching all my 2209s and 2226s into X socket to test if any of them work.
