I appreciate your responses. If I wanted to try to edit the post processor, Which file would I need to edit? Is it the .cnc or .cnx file? The .cnx file is easile opened with wordpad, but the .cnc file has a lot of unreadable entrys. When I post a new part program, I load the Boss6I.cnc file into my CAD program to generate the G-code, so I don't know what the purpose of the Boss6I.cnx file is for.
