* Since each CNC Controller speaks a specific G-Code dialect, a Dialect-correct Postprocessor translates the internal agnostic FreeCAD G-Code to the machine's G-Code dialect. Several Postprocessors are included allowing direct use or as a template for modification. Postprocessors contain configuration flags and are designed to be tuned by adding G-Codes and M-Codes to provided definitions for:
**Machine initialization
**Job finalization
**Tool-Changes
**Cooling on /off
**Etc...

The FreeCAD Path Workbench workflow creates these machine instructions as follows:

  • A 3D model is the base object, typically created using one or more of the Part Design, Part or Draft Workbenches.
  • A Path Job is created in the Path Workbench. This contains all the information required to generate the necessary G-code to process the Job on a CNC mill: there is Stock material, the mill has a certain set of tools and it follows certain commands controlling speed and movements (usually G-code).
  • Path Tools are selected as required by the Job Operations.
  • Milling paths are created using e.g. Contour and Pocket Operations. These Path objects use internal FreeCAD G-code dialect, independent of the CNC machine.
  • Export the job with a G-code, matching to your machine. This step is called post processing; there are different post processors available.
