For years we've been running Giben saws with .AC files, and although we've had .AD files at the same time I don't believe they were ever required. Now we are setting up a newer Giben saw (ICON 2) with GDrive software instead of G57, and assuming due to its ability to label, it requires the .AD file as well. Problem is that we see errors when opening them, seems the format is off. Can anyone send me a sample of their .AD files or the formatting specs for them?
