NcThumbnail is a service that is installed on a computer running Windows Vista or newer operating system. After installation, all the CNC programs (G-code) on your computer will be represented by a thumbnail (small picture) when browsing directories with Windows Explorer. (Just as you see thumbnails of your pictures from your digital camera) NcThumbnail supports both lathe and milling programs. NcThumbnail supports most common CNC formats like Fanuc, Heidenhain and Siemens. It can also be used for other formats that use similar codes. No cycles are currently supported.
