+## Intro
+
+This post is written in context of using the BigTreeTech CB1 as your klipper controller for your 3d printer. But most of the points here are also usable for other projects with the raspberry pi alternative. Its about cleaning up the network configuration, enable canbus if the cb1 is installed on a BigTreeTech manta port and last but not least to enable the bigtreetech tft35 spi to show your graphical environment. Here to be used with the well known klipperscreen project - but for whatever your project is about.

+## Install basic armbian image
+
+### Install on SD Card
+
+### Install on internal EMMC storage
+

+
+  - Download [sunxi-tools](https://github.com/bigtreetech/sunxi-tools)
+  - For windows also download driver installer [zadig](https://zadig.akeo.ie/)
+  - Download armbian Image [text](https://www.armbian.com/bigtreetech-cb1/). Suggest the current minimal/IOT version Bookworm Minimal
+
+- Install driver
+- Switch to external usb storage mode
+- Flash armbian with balena etcher
+- change dbo to emmc
+
+## configure networkmanager
+
+- connect via ethernet (ssh root@bigtreetech-cb1)
+- sudo apt install network-manager
+- sudo apt remove netplan.io (conflicting with systemd-networkd/networkmanager)
+- remove /etc/systemd/network/
+- nmcli device wifi connect `Your SSID` password `Your Password` ifname wlan0
+
+## cleanup systemd-networkd
+
+sudo systemctl disable systemd-networkd-wait-online.service
+sudo systemctl disable NetworkManager-wait-online.service
+
+## configure canbus
+
+/etc/systemd/network/can0.link
+-> has currently no effect, workaround with udev rules below
+
+```systemd
+[Match]
+Type=can
+
+[Link]
+
+TransmitQueueLength=128
+```
+
+/etc/systemd/network/can0.network
+
+```systemd
+[Match]
+Name=can0
+
+[CAN]
+BitRate=1000000
+RestartSec=10s
+```
+
+### workaround
+
+/etc/udev/rules.d/80_can.rules
+
+klipper recommends tx_queue_len of 128
+
+```sh
+SUBSYSTEM=="net", ACTION=="add|change", KERNEL=="can*", ATTR{tx_queue_len}="128"
+```
+
+## configure tft graphics
+
+/etc/X11/xorg.conf.d/99-tft35.conf
+
+```xorg
+Section "Device"
+  Identifier      "FBDEV"
+  Driver          ""
+  Option          "fbdev" "/dev/fb0"
+  Option          "SwapbuffersWait" "true"
+EndSection
+```
+
+## disable systemd reboot watchdog
+
+/etc/systemd/system.conf
+
+```systemd
+RebootWatchdogSec=off
+```
+
+## install klipper stack
+
+manual or with kiauh
+[Klipper Installation And Update Helper](https://github.com/dw-0/kiauh)
+
+- step by step
+- klipper
+- moonraker
+- mainsail
+- klipperscreen
+
+  - if asked for xorg or wayland use wayland
+  - if asked for networkmanager, say yes
+
+- optional
+  - crownest (for cam streaming)
+  - obico
