 - **Mesh to PDF**: Generates a 1:1 true-scale 2D top-view (+Z orthographic) vector PDF from a `SlicingGroup` or `SlicingCollection` with a custom grid and background color. Subpanel menus are collapsed by default.
     - **Technical Drawing Header**: Collapsible menu containing string inputs for technical drawing info (Company, Part Name, Drawing No., Author, Revision, Material, Tolerance). If Part Name is left empty, it automatically defaults to the name of the first object being rendered. Automatically computes ISO date and scale length (`1:1`). Renders an ISO/DIN technical drawing header table on the bottom-right of the drawing.
     - **Geometry**: Input socket accepting a single geometry (`SlicingGroup`, `SlicingCollection`, or `SlicingObject`). Join multiple geometries using Join Geometry nodes.

+### Gcode Processing
+- **Paths to Gcode**: Converts `SlicePaths` into G-code blocks.
+    - **Header**: Toggles the generation of standard NodeSlicer G-code headers and units setup.
+- **Gcode Block**: Manual text area for entering raw G-code.
+- **Gcode Regex Replace**: Performs regex search and replace on G-code.
+- **Assign Metadata**: Injects custom metadata comments into G-code.
+- **Gcode Helper**: Utility helper functions for G-code stream modifications.
+- **Load Gcode**: Reads a G-code file from disk.
+
+### Utility & Joiners
+- **Join Mesh**: Merges multiple `SlicingObject` instances into one.
+- **Join Paths**: Combines multiple `SlicePaths`. Supports Sequential or Interleaved modes.
+- **Join Gcode**: Concatenates multiple G-code strings.
+- **Join Settings**: Sequentially merges multiple override dictionaries. Later inputs overwrite earlier ones for matching keys.
+- **Join Execution**: Synchronizes sequential execution flows.
+
+### Action & I/O
+- **Gcode to File**: Writes G-code string to a file on disk.
+    - **Automatic Binary Conversion**: If the G-code contains the comment `; binary_gcode = 1`, the node automatically converts the output to Prusa's binary G-code format (`.bgcode`) using MeatPack encoding and Heatshrink compression.
+- **Gcode to Text Block**: Creates a new Blender text block containing the G-code and opens it in any active text editors.
+- **Start Print**: Sends G-code directly to a network printer.
 - **Baserow Submit**: Sends G-code and metadata to a Baserow database.
     - **Host**: Baserow host URL.
     - **Token File**: Path to a file containing the Baserow API token.
