Calibrating only needs to be done when the scans are looks bad or when the scanner is moved and the camera/lasers might have been jostled.
With each scan the camera exposure is adjusted for the lighting, so just changing the lighting does not require re-calibration. I've tried several lighting setups and found that the scanner worked well in all of them as long as the shadows were not harsh. I tried it in my basement directly under one of the 4 recessed lights and it worked pretty good. Even, diffuse light created by the overhead lighting we have in the space will work very well.
Not much more I can add to their instructions, it's pretty straight forward. Put the item on the scanner, open the software, click New Scan, select Single Coloured (it still does a color scan), and then wait. Scans are slow (10-15 min per rotation * the number of elevation steps). You can clean up the finished scan to remove random points and the scanner bed, then save it.
