If you are looking for instructions on How to build your own Astrobox with a Raspberry Pi 3, follow this guide.
AstroPrint currently supports Raspberry Pi 3, but there ARE some caveats, namely: You will need an additional WiFi dongle along with the Raspberry Pi 3’s built-in WiFi.
Why exactly do I need another WiFi dongle when the Raspberry Pi 3 has built in WiFi?
The built-in WiFi on the Raspberry Pi 3 cannot maintain a simultaneous network connection to your WiFi network and broadcast it’s own hotspot like we require on our Astroboxes. Therefore, the built-in Raspberry Pi 3 WiFi is not sufficient for our purposes at this time.
In order to circumvent this, you will need an additional WiFi dongle to make an Astrobox using a Raspberry Pi 3 board.
With that said, the built in Raspberry Pi 3 WiFi is still used.
The need for the additional WiFi dongle is mainly to support hotspot functionality.
Note: If you don’t need hotspot functionality, it is possible to use a Raspberry Pi 3 without a WiFi dongle. You’ll need to be aware of the Astrobox’s IP address while you set it up for the first time using ethernet, though.
