Cordyceps is a Grasshopper plugin designed for generating and simulating G-code toolpaths for CNC machinery and 3D printers. Cordyceps functions as a computational tool within the Grasshopper environment, enabling the direct translation of geometric data into machine-readable G-code. It streamlines the workflow between digital modelling and physical fabrication by providing an integrated interface for path generation and simulation. The plugin is structured to handle complex toolpath requirements, allowing users to define parameters for CNC milling or additive manufacturing processes. By bridging the gap between Rhino geometry and machine instructions, it facilitates a more efficient transition from design concept to tangible production, ensuring precision and control throughout the fabrication process.

The download is a 573 KB file containing .GHA files.

Users install the GHA file into their Grasshopper libraries folder to access the custom components. The workflow involves connecting Rhino geometry inputs into the Cordyceps nodes, where toolpath parameters such as feed rate, step-over, and machine-specific settings are configured. Once the toolpath is generated, the integrated simulation feature allows for visual verification of the path before exporting the final G-code file for the physical CNC or 3D printing hardware.

This tool is essential for architectural practices and industrial design studios engaged in digital fabrication and rapid prototyping. It is particularly valuable during the design development and production stages where custom CNC components or complex 3D printed models are required. Professionals use Cordyceps to maintain parametric control over their fabrication logic, ensuring that geometry modifications are immediately reflected in the machine output. It is a critical asset for projects involving bespoke furniture, intricate facade panels, or experimental architectural models requiring high-precision manufacturing workflows.
