No, the system does not report this for fun. Apparently your power source is not sufficient. This is very likely to cause issues.
I do not care about YT and surely do not check if the video is of any use. Follow:
- Installing Klipper with KIAUH
- Make sure your board is really a v3.0. There is a v3.0.1 that has different settings
- Likely your board is not correctly flashed or connected. The
dmesgoutput does not show any traces of a board - Follow Issues flashing the printer board for pointers of what needs to be observed when flashing / connecting a board
- The serial path in your config
/dev/serial/by-id/usb-Klipper_Klipper_firmware_12345-if00is definitively wrong as this is a placeholder path and needs to be replaced by the true value - For a detailed description of the board refer to BIGTREETECH-SKR-mini-E3/firmware/V3.0/Klipper at master · bigtreetech/BIGTREETECH-SKR-mini-E3 · GitHub and again mind the correct board revision
