Ender 3V2 install problems

First , I’m total new with this… and I’m busy for a couple of days, and it stil not works…
and I also new with Linux/Raspberry PI …

Okay I try to get my Ender 3V2 to work with klipper…

I install all on the PI , en that part is working…
I flash my Ender, but how do I know that went well?

now , if I connect my Ender and the PI…

I see in the Klippy.log :
mcu ‘mcu’: Unable to open serial port: [Errno 2] could not open port /dev/serial/by-id/: [Errno 2] No such file or directory: ‘/dev/serial/by-id/’

if I check, with putty : ls /dec/serial/by-id/*
I get this: /dev/serial/by-id/usb-1a86_USB_Serial-if00-port0

in the printer config file, i have by
[mcu]
serial: /dev/serial/by-id/usb-1a86_USB_Serial-if00-port0
restart_method: command

but what do I wrong? why I still get :
mcu ‘mcu’: Unable to open serial port: [Errno 2] could not open port /dev/serial/by-id/: [Errno 2] No such file or directory: ‘/dev/serial/by-id/’

Help please!

Hello @Swets !

Please attach the Klippy.log to your next post.

sorry for the late reply, but it works now… I don’t know what I did wrong… I follow 3 different tutorials/YouTube movies… Now I go try do the same with my Geeetech A10T printer… (if I can found info about that)…
