CNC Threaded Lid Box | FreeCAD CAM Tutorial + Free Macro
In this tutorial, you’ll learn how to create a CNC threaded lid box using FreeCAD CAM and a free macro. Follow along as we go from 3D modeling to CAM setup, toolpath generation, G-code export, and CNC milling.
This project covers:
Modeling a round box and threaded lid in FreeCAD
Using the subtractive helix tool for external threads
Setting up CNC jobs, stock, and origin in FreeCAD CAM
Applying adaptive, pocket, and profile operations
Installing and using the FreeCAD threaded lid macro
Exporting and editing G-code for CNC milling
This is a complete CAD to G-code workflow for anyone looking to master CNC threads with FreeCAD.
