Have a look at my answer here Ender 3v2 Neo Custom - #4 by hcet14. I wrote it just a couple of minutes before.
You got the same problems as @JosevdG
If you solved your problem, you could help JosevdG.

dmesg.txt (32.8 KB)
I cannot understand what is displayed when I run sudo dmesg - e .
Can you help me read it

When I run ls/dev/serial/by id/*, it shows


pi@mainsailos:~$ ls /dev/serial/by-id/*
/dev/serial/by-id/usb-Klipper_stm32f407xx_44545-if00

Both your ls command and the dmesg is looking fine and the klippy.log you posted indicates that Klipper is successfully connecting to the board.

Your error is Lost communication with MCU ‘mcu’, which has a different source than what you are looking at: Timeout with MCU / Lost communication with MCU

Unfortunately, this error can be tricky to hunt down, but is 99.99786% related to your hardware.

Thanks, I have solved this problem by replacing the data cable

Seems like this figure should be slightly higher now.
