NodeDSF

NodeDSF is a set of nodes which enable Node-Red to interface with the Duet Software Framework (v3+) running on an SBC.

The Duet Software Framework (DSF) is part of a suite of software components (from Duet3d) that manage control boards running RepRap firmware, which execute g-code to operate a physical machine. This is typically used by 3d Printers, CNC machines etc..

DSF calls anything connected to a control board a Machine, and constructs a Machine Model representing the current state of the entire Machine and its associated components.

DSF can output its Machine Model to a client via a web-socket. NodeDSF enables the connection and provides a set of nodes to use the Machine Model in Node-Red.

The Machine Model is a JSON object representing the current state of the Machine which is constantly updated by DSF and passed to the connected web-socket client.

NodeDSF has 5 nodes:

• dsf-connector (control node) : Stores the connection details enabling the web-socket connection to DSF.
• dsf-monitor: Creates the web-socket connection to DSF and processes the Machine Model updates.
• dsf-event : Parses the updated Machine Model for a specified object value change, and triggers when a match if found.
• dsf-intercept: Watches for specially formatted messages embedded within running g-code to trigger events within Node_Red.
• dsf-command: Send a g-code or m-code command to DSF for action.

Please refer to the NodeDSF wiki on github for detailed instructions on usage, and example flows.
