oh thats why i never encountered the ch341/ch340 error, i started with the cli/minimal install

please post output of the following commands while the printer is plugged in the usb and is turned on. ls /dev/tty* and lsusb i never had problems with usb serial communication with armbian before. please check your klipper make menuconfig settings and that it is exactly what is intended for your printer mainboard. here is the guide for your printer.

open nvram_2734с.txt copy and paste all the contents and in the loaded config. bcmfmac4330* or brcmfmac4334* in /lib/firmware you can install klipper with kiauh just fine with this build of armbian i've been using it for 3 years now. you just need git installed and clone kiauh repository for a very convenient klipper install.
