You can locate the path to the material file by following these steps.  After locating the file simply copy it to the same location on your other system/version.
  • Launch GibbsCAM
  • Go to Plug-Ins >Misc >Pathfinder >CutData Folder

This will open a window with the Material.txt file.  This is the file that contains your material data.  Do not open this file in a text editor as this will cause the data to become corrupted.

The Communications Settings are also located in this folder.  The file is called Protocol.txt.
