Reflashing/ Imaging BIQU Hurakan OS Guide:


Link 1: BIQU Hurakan OS Download (required) (warning large file: 5GB+ unzipped)

https://github.com/bigtreetech/CB1/releases/download/V2.2.1/Hurakan_Debian11_Mainsail_kernel5.16_20221119.img.xz

(check https://github.com/bigtreetech/BIQU-Hurakan/releases for newer releases)

Link 2: Raspberry Pi Imager Page (required)
https://www.raspberrypi.com/software/


In order for the printer to be able to read the files, the OS file for example "ExampleSoftwareV2.img" needs to have all internal files and folders extracted to the card, which is what Raspberry Pi Imager is for.


Step 1: Download necessary programs and files

Download link 1 (BIQU Hurakan OS Image) and the software from link 2 (Raspberry Pi Imager).



Step 2: Install application

Install the Raspberry Pi Imager application


Step 3: Start application and load file

Run Raspberry Pi Imager and you should be greeted by this menu (see image below). Select "Choose OS" and scroll down the menu of Operating Systems until you find "Use custom". When you select this, you can browse to find and select the zipped OS file downloaded earlier. In this case the name is "Hurakan_Debian11_Mainsail_kernel5.16_20221119.img(1).xz" located in the Downloads folder.


Step 4: Select storage device

Once you find the OS file, click "Open" and you will return to the main menu. Now "Choose Storage" to select the storage device (the Micro SD Card) to be formatted and flashed with the OS. Plug in the OS card to the card reader and select it (name may be unrecognisable but if using the original Micro SD Card it should be around 30GB). Note: Take care to choose the correct device and that there is no important data stored, as the data is going to be erased.

Step 5: Modify settings and start imaging

Once you select the card, you will once again return to the main menu. Now the "Next" button should be lit up. Click it, and a message stating "Would you like to apply OS customisation settings?" will appear. Select "Edit Settings" to gain access to options like enabling SSH, editing the default username and password, etc. Otherwise select "No" and the card will begin the imaging process which will take some time. When completed, you will recieve a new message stating that the device has been successfully imaged and can be removed.

Message that appears before imaging the storage device (Micro SD card):


Step 6: Begin using on printer

When the imaging is complete, disconnect the card and insert it into the OS card slot of the machine. Start up the machine, and after some waiting it should boot into it's main menu ready to print.
