The MILL module uses macro files with a .spm file extension to handle post-processing to different controllers. These files are typically located in the "Posts" directory under the VisualCAM installation folder(C:\ProgramData\MecSoft Corporation\VisualCAM 2025\Posts\Mill).

The MILL module by default looks in this directory to build the list of available post-processors shown under the Current Post.
