OctoPrint on A Raspberry Pi

Posted on Edited on In ,

Finally, I got some time for OctoPrint, another specific operating system for Raspberry Pi, as Home Assistant talked in my previous blog Home Assistant on A Raspberry Pi.

1. Overview

1.1 What is OctoPrint?

From its official website, clearly, OctoPrint is an operating system for 3D Printing. Its capabilities can be extended to other manufacturing fields. Specifically, OctoPi will work on a Raspberry Pi.

2. ssh Into OctoPi

2.1 FIRST Login

You got to login OctoPi locally for the FIRST time, instead of remotely, for the NetworkManager service is NOT started by default. Namely, there is NO Wi-Fi by default. Well, you can ALWAYS use the wired connection of course.

2.1.1 Start NetworkManager Whenever Reboot

Use the following commands:

  • sudo systemctl status NetworkManager
  • sudo systemctl enable NetworkManager
  • sudo systemctl start NetworkManager
  • sudo systemctl status NetworkManager for double check
  • sudo reboot reboot to ensure NetworkManager is started by default
  • sudo systemctl status NetworkManager check again

2.1.2 nmcli to Set Up Wi-Fi

Use the following commands:

  • nmcli dev wifi list
  • nmcli dev wifi connect NetworkName password WiFiPassword (You don't need to quote or double-quote NetworkName or WiFiPassword)

Now, you’re good to go.

2.2 ssh Into OctoPi Via Wi-Fi Connection
