FDM Connector

The FDM Connector is an OctoPrint plugin that simplifies the initial connection to FDM Monster. The plugin is also expected to facilitate setting up a tunnel connection and tracking filament usage in future versions.

Current feature(s)

• Auto-registration - Send your OctoPrint connection parameters to FDM Monster securely to make setting up printers a breeze.

Future features

• Filament Pedometer - Send filament usage data to FDM Monster, cooperating with the plugin SpoolManager without external database (Filament Manager is not our aim).
• Http Tunnel - Connect to FDM Monster to make connection to printers easy, especially over docker, VPN, DMZ, VLAN, the cloud, or other complex network setups.
• Single-Sign-On - Client-to-machine (C2M) and machine-to-machine (M2M) authentication, removing the need for more than 1 set of credentials across the farm.

Setup

Note: This plugin is currently in the alpha stage and requires the plugin system on FDM Monster, which is not yet released.

To install the FDM Connector, use the bundled Plugin Manager or manually use this URL:

https://github.com/fdm-monster/fdm-connector/archive/main.zip

Configure the plugin completely for one or more printers before checking FDM Monster.

Configuration

Warning - restoring from an OctoPrint backup can be a cause of security weakness due to copied passwords. In the end, we are not responsible for your choices, but we advise changing the accessControl:salt and regenerating the main user account for each OctoPrint instance.

Configuration - auto-registration

Properly configuring the auto-registration can massively improve the steps you need to undertake to set up your farm.

• REQUIRED fdm_host: the host to reach FDM Monster with (IP, localhost, domain name, etc)
• REQUIRED fdm_port: the port to approach the FDM Monster server (number)
• REQUIRED oidc_client_id: the client ID to authenticate with the FDM Monster server using OpenID Connect (string)
• REQUIRED oidc_client_secret: the client secret key to authenticate with the FDM Monster server using OpenID Connect (string)
• OPTIONAL port_override: the announced port for how FDM Monster can reach OctoPrint later (default is taken from server:port, but this is not always correct in case of Docker or a proxy.)

We understand if you restore OctoPrint backups to install new OctoPrints. For that reason, we've introduced two unique IDs (UUID).

• AUTOGENERATED persistence_uuid: a unique identifier stored in the plugin folder in device.json, which is excluded from backups to prevent duplicate printers. Don't adjust this if you don't understand it.
• AUTOGENERATED device_uuid: a unique identifier stored in the config.yaml at startup. Don't adjust this if you don't understand it.

Periodic updates

• OPTIONAL ping: the time in seconds between each call to FDM Monster (default is 15 * 60, or 15 minutes)

The ping setting specifies the frequency at which the plugin will send updates to FDM Monster. The default is every 15 minutes, but you can adjust this value if you prefer a different update frequency.

Conclusion

FDM Connector is an OctoPrint plugin that simplifies the initial connection to FDM Monster and offers future features such as filament usage tracking and tunnel connection setup. The plugin is currently in the alpha stage and requires the plugin system on FDM Monster, which is not yet released.
