Describe your issue:

I am trying to get my printer going, I keep getting this Error message. I’m trying to use the TMC2209 drivers.

I have the UART pins jumped as well as the HF pins for the power and extra 24V supply running into the motors connection on the board. I have also tried mowing the power jumper to run from board supply to no avail. I have checked all the fuses on the board too and they’re all good.

I have tried switching the ports on the board, changing the drivers, and even changing the motors. It’s always showing on stepper_z or z1 when I tried to run them on separate driver boards. I know that the motor 3 and 4 ports are wired in parallel for running two z axis steppers

M1- stepper_x

M2- stepper_y

M3 -stepper_z

M4- stepper_z1

M6- extruder

If anyone has any ideas I would appreciate the support.

For Z1 you have

[tmc2209 stepper_z]
uart_pin = PB9
uart_address = 2
run_current = 0.800
stealthchop_threshold = 999999

My guess id the uart_address is wrong.
I also note you have commented out the uart section for Z1

Thank you very much. It was a simple mistake that fixed the issue
