OctoPrint provides a web interface for controlling consumer 3D printers.

The web interface is accessible via port 5001:

  • URL = http://<your.IP>:5001

Once you are connected to the web interface, simply run through the setup wizard and configure the software and printers as needed. A login user and password needs to be created, but it does not need to match any existing UNIX login user, i.e. can be freely chosen.

  • Base directory: /mnt/dietpi_userdata/octoprint
  • Data and config: /mnt/dietpi_userdata/octoprint/.octoprint
  • Main config file: /mnt/dietpi_userdata/octoprint/.octoprint/config.yaml
  • Binaries and plugins: /mnt/dietpi_userdata/octoprint/.local
  • Service and core logs: journalctl -u octoprint
  • Log files and plugin logs: /mnt/dietpi_userdata/octoprint/.octoprint/logs/
  • Configure logging via web interface > Settings > Logging

OctoPrint offers a command line interface to execute OctoPrint commands. To use it, simply run octoprint --help from the command line.

The current shell needs to be bash and the user needs to be allowed to use sudo, as the above command is an alias to call a local OctoPrint binary as system user octoprint. The alias is defined in /etc/bashrc.d/, which is loaded automatically from bash shells. But you can as well load it from non-bash shells, if required.
