Use these options to define the post type to use when posting toolpath operations.  Each option is documented further in the Post-processor Generator On-Line Help.  

Use Legacy Post

Select this option to use your "Legacy Post" when posting toolpath operations. "Legacy Post" refers to your post definition (*.spm) file you used prior to version 2021.  This option also lists the over 300 existing post-processors.  See Current Post Processor below.

Use Programmable Post

Select this option to use your "Programmable Post" when posting toolpath operations. "Programmable Post" refers to your programmable post created with our version 2021 and newer CAM plugins.  This option will list only one post processor selection called PostModifier.  This post definition is defined using the Programmable Post API.

You can change the default post processor by selecting a post from the list of available post processors under Current Post Processor.  If Use Legacy Post is selected, the Current Post Processor list will contain MecSoft's standard list of over 300 post processors.  If Use Programmable Post is selected, this will list only one post processor selection called PostModifier.  This post definition is defined using the Programmable Post API.  Refer to the Programmable Post API documentation for more about the API.

MILL module uses macro files with a .spm 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 2024\Posts\Mill).
