SKR V1.3 + FYSETC TMC2209 V2.1 steppers not moving

[NSchnitzler]

Hello everybody,

i have a non-pro SKR V1.3 and FYSETC TMC2209 V2.1 stepper drivers, the board is flashed with the marlin fw. All jumpers below the stepper drivers are removed, the UART Jumpers are set. The communications seems to work, here is the TMC Debug output:

I have tried stealthChop and spreadCycle mode, but the steppers (lying on the table, without any mechanical connection) are just vibrating, not turning. I have checked the Wiring so that one coil is connected to the outer pins and the other to the inner pins of the motor connector of the board. After hours of investigation, i ran out of any idea how to make the setup work. Does anyone have an idea how to solve this issue?

thanks in advance!

I have found out, that the z-axis works as expected. But if i switch the driver, stepper and cable to x or y, the stepper doesn't move.

Has anyone an idea how to solve this?!

I would try to swap 2 pins on the motor connector for example, Creality engines have interchangeable terminals with NEMA engines

i have tried all combinations of the motor wiring.
