From web GUI :

In palette 3 settings :
baudrate 115200 (and I have tested with 250000 when 250000 also on klipperotchy)
/dev/ttyACM0
But connect button doesn't work :///

root@DietPi:~/Klipperotchy/tools/serial_moonraker_bridge# python3 serial_moonraker_bridge.py --baudrate=250000 --moonraker=10.0.254.240:7125 --serial=/dev/ttyGS0 --log=INFO
Listening palette
Listening moonraker

No more trace when I test to connect Palette3, do you have an idea ?
~~Also what is the default port used by palette3 to connect view screen ?~~ ~~I have tested with only IP but not work :~~
(Edit: Palette 3 port 5000 for webGUI)

I hope it's clear despite my bad English don't hesitate to ask me for more information and tests to do

Note: Usb cable is good with data transfert with old smartphone. Note2: I had an error following the readme for the service, the git clone was done in the user folder /home/dietpi/, but when the service starts it looks in the /root/ folder which doesn't work, I'd have to modify the readme to do a sudo -i before doing the cd ~/ && git clone.
