What happened?

I am designing a laser cutting machine based on ESP32. I met a problem , steppers (XYZ) drive by TMC2209, but everytime only one axis can be detected at the beginning. If I plug in all the TMC2209 modules any axis can not be detected （Axis TMC driver not detected - expected 0x0x21 got 0x0x0）.Even have one axis can be detected at the first time, after reinitialize ($MI) all the axis can not be detected.

If I plug in one TMC2209 module, only one axis can be detected (at the first init). More then two TMC2209 modules plug in all the axis can not be detected.

Show a photo of the controller. How do you set the address on the drivers?

I try to change the resistance between Urat1 TX and RX ，from original 1kΩ to 330 Ω， it seem more than one aixs can be detected now （even $MI）. Yesterday I burned a TMC2209 module due to an operating error. So I can't test it completely today.I will test it again when the new module arrives.

I set the address via jumpers.

Finally, I adjusted the resistance to 100Ω, and the problem seemed to be solved, and all three axes could be recognized normally.
