So I managed to get past the serial by using the rpi MCU. Now I am trying to figure out how to get past all the config settings like pin name, velocity and so on

Found the solution. Still testing but looks promising.

`[mcu]
serial: /tmp/klipper_host_mcu

[printer]
kinematics: none
max_velocity: 1
max_accel: 1`

this is just a bot. you can use the #NoLogsNeeded in the description for question like this ( #readme for more informations about this)

yes. this looks like my "guide" in the klipper discord.

you have to install the raspberry pi mcu (host mcu) first like here: https://www.klipper3d.org/RPi_microcontroller.html

so short guide:

# install klipper mcu service
cd ~/klipper/
sudo cp ./scripts/klipper-mcu.service /etc/systemd/system/
sudo systemctl enable klipper-mcu.service

# build micro-controller code
cd ~/klipper/
make menuconfig

# In the menu, set "Microcontroller Architecture" to "Linux process," then save and exit.

sudo systemctl stop klipper
make flash
sudo systemctl start klipper

# add user pi (if you use another username, change pi to your username) to tty group
sudo usermod -a -G tty pi
