IDEX Sensorless Homing

I have a Fysetc Spider V1.1 with TMC2209 and after checking all config, It’s everything working, but when I set SET_TMC_FIELD at 255 for the dual_carriage, doesn´t seem to work. it’s moving and I changed the pin but no success. I tried already a few combinations, also changed X stepper driver to match with the DiagX+.
Stepper X runs normal and works like it should. Any ideias on what’s happening?

What are you trying to achieve? Are you talking about:

SET_TMC_FIELD STEPPER=stepper_x FIELD=SGTHRS VALUE=255

Please also refer to:

yes. doesn’t work. I want to Home the dual carriage, the X works fine, but the dual carriage doesn’t stop with sensorless homing. So now I tried to work only with the dual carriage, named to Stepper X and the problem stays. Tried to use the other Diag pin, also no success.

Did you correctly set the corresponding Diag jumper on the board?
Does the pull up (^) make a difference?

Yes,
^!PA1 Endstop Open
^PA1 Endstop Closed
PA1 Endstop Open
!PA1 Endstop Closed

But no diference. I have always to run M112. I created a ticket on Fystec as well.
