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
