To find the Wire EDM post processors follow these steps: Launch GibbsCAM Go to Plug-Ins→Misc→Pathfinder→All Users Preferences In the window that appears double-click the EDM folder Double click the Posts folder If you have a customized EDM post processor you would place the two files in this folder. If you wish to attempt to customize your own post processor the .PP file is the actual post file. Be careful making any changes to the post and be sure to create a back-up file.
