Good idea ark19,

I think they could have put slots in the turntable to stop the frame moving, or some round holes, then your angled frame could sit in these.
Like you've noticed it just has to be held at roughly the right angle for the calibration maths to do its work, so congrats on halving the frame members to do the same task.

Reading your comments elsewhere, I think we are all a little early to the Einscan-S show at the moment, and as an ex-designer (as if you ever are an ex) some of the design decisions are a little bizarre and not thought out too well when you come to use it.
As others have mentioned too, the software interface is somewhat lacking, and not typical in it's layout, but we all hope it will be refined as the months go on. Some of the other software Shining3D produce looks very good.

I also read your comments about the MatterandForm, which made me smile as that was a crappy scanner, but well packaged, as you said.
I was so disappointed with it, I returned it within a few days, and it just cost me the return postage.
