Describe your issue:

Hey everyone, i get the error code
“mcu ‘mcu’: Unable to connect
Once the underlying issue is corrected, use the
“FIRMWARE_RESTART” command to reset the firmware, reload the
config, and restart the host software.
Error configuring printer”
I have no idea what i could be dooing wrong, i tried browsing similar treads but it wanst any help. Thank you in advance!

Your board is not flashed with a Klipper firmware. In fact the screenshot and also the klippy.log already provides you the information that it is running the Marlin firmware.

  1. See Installation - Klipper documentation or Installing Klipper with KIAUH
  2. For the applicable config: klipper/config/generic-bigtreetech-skr-v1.4.cfg at master · Klipper3d/klipper · GitHub
