Disabled to connect to OctoPrint

Hello everyone!

I'm trying to use klipper for controling stepper motors, but is doesn't connects. This is the error: No working connection parameters could be found. Are you sure your printer is physically connected and supported? Refer to the FAQ for help in debugging this. Can you tell me what should be problem?

I'm using raspi 4b, which is connecting to raspi pico H. TMC 2209 Tx pin is in raspi pico H Rx pin and TMC's Rx pin is in raspi pico's Tx pin. This is my printer.cfg file:

[tmc2209 stepper_x]
uart_pin: 11
run_current: 0.6

[tmc2209 stepper_y]
uart_pin: 16
run_current: 0.6

serial: /dev/ttyACM0

kinematics: corexy
max_velocity: 300
max_accel: 500

baud_rate: 115200

Can anyone help me?

Hello @raspi !

You connect OctoPrint to Klipper via the virtual printer /tmp/printer

Klipper connects to the printer on it's own.

The TMC RX/TX pins are only for the communication of Klipper with the TMC stepper drivers.

For further help please consult the Klipper forum.
