Hi Hughes & 3DWP,

You have to recalibrate when you install the new software because the calibration file is removed in the un-install sequence. If you saved or copied it from the turntable reference before doing this, I'm sure if you copied it back into the new folder and the name was the same, the software wouldn't know any better.

As to how often, well I do it once for the turntable, then use it in freescan mode, however, if I was to put the camera back on the turntable, I think the freescan alignment meshes would interfere with the turntable alignment. If I have a tubular object on the turntable, it scans as an eight sided petal shaped one, and won't necessarily self align when it creates a mesh. This isn't a problem if you sab=ve as an .asc file, as you can align in Meshlab or similar.
