Thanks. I've tried everything with the mat size and orientation. I am using Windows 7. I have tried reinstalling the drivers and the SCAL software. Now the output trough "shows" in the right orientation, but the vinyl skips the first 10". I've tried resetting the Origin and it still skips. It also stops whereever it is at the end of a cut instead of returning to Origin. Perhaps I'm not doing it right but I've been unable to find the manual.
