What does HackerNews think of octo4a?

Use your old Android device as an OctoPrint server.

Language: Kotlin

#41 in Android
I discovered the other day that you can use your old android phone as a server for OctoPrint, a 3D printer controller that runs off a web interface. I am going to give this a try using my old OnePlus 3T.

This is a pretty old thread at ~12 hours, but there's someone putting in an active effort to enable OctoPrint to run directly off of an Android device. Still pretty early days. The author currently still distributes and gathers feedback through the linked Telegram group.
