• Use standard Debian source to replace Tsinghua source.
• Install the mDNS service. Now we can scan the host name through Angry IP Scanner software, More importantly, if there is only one CB1 device in the LAN, we can access it directly through "http://<host_name>.local" (The default of the hurakan OS is http://Hurakan.local else is http://BTT-CB1.local) without trying to get the IP. If there are multiple CB1 devices in the same LAN, the hostname will be automatically incremented to BTT-CB1-2.local, BTT-CB1-3.local, etc. We can still access it through http://BTT-CB1-2.local, http://BTT-CB1-3.local
• The Hurakan version OS adds a custom Mainsail theme.

Note

• If you use a minimal version of the image, additional settings are required after installing klipperscreen.

  • sudo apt install xserver-xorg-input-libinput for USB-HID touch
• The version of the Hurakan OS can only be used on Hurakan printer motherboard (Because there is a custom startup logic). Pay special attention not to directly flash the EBB with the klipper provided by Hurakan, otherwise the HE0(heater) port will be in the heating state until klipper takes over control.

Known issues

Kernel 5.16

• The Ethernet driver of this version is still under debugging, You can use the kernel4.9 image first if you prefer to use the Ethernet rather than WiFi

Kernel 4.9

• HDMI output is still under debugging

V1.1.0

CB1_Debian11_bullseye_minimal_kernel4.9_20220730.img

• This image is minimal Debian11 file system. Please contact here for detailed information and feedback

Know issues

• After successfully connecting to WIFI, the system will save the current connection information and automatically connect this WIFI after the next restart. When setting a new WiFi in the configuration file again, the system will first try to connect to the previously saved WiFi after startup. When the previous WiFi cannot be connected, it will try to connect to the newly set WIFI (This connection logic will be optimized in the next version, and the WIFI priority set in the configuration file will be set to the highest)
• The HDMI resolution of this OS does not support non-standard, such as 1024x600, 800x480. We are adapting to the next version and will add this support

V1.0.2.1

Optimized point relative to Hurakan_20220722_4.9_ubuntu21.10.img.xz

• Clean up git proxy setting
• Klipper source code make clean
• Fixed the problem that the configuration was not saved when the file was modified (bed mesh, etc.) and powered off immediately
