The physical geometry of projector, object, and cameras combined with the scanners technology = many data voids.
The distance and angles of these things all relate to accuracy and data voids, etc...
The Steinbichler has the least voids as it only needs One camera.
When you go to Twin camera technology (both cameras need to see same thing to produce data, and both cast a shadow that the other cannot see into)....the closer together the cameras, the less voids. (Like the Medit) but I think a tiny amount of accuracy is lost.
So, how far apart are your cameras? I think this is your problem. Is this Open Technologies scanhead inside that box of yours?? If so, then the cameras are probably very far apart, relativily speaking.
The plus is that you probably have very accurate data with that set-up of geometry, but as you are now finding out....the downside is data voids.
Seven shots on a steinbichler pretty much does everything on a standard model.
The older smart optiks I had was at the opposite end with many voids along with the OpenTechnologies scan head being used on Nobil Metal Spa's scanner.
Too many voids! Annoying. I think it is the same or very similar geometry as your abc scanner.
