gpio mode 3 out
gpio write 3 1 (to enable 4.5v)
Dumb question: Can I do this from a terminal window, or do I need to make a batch file or python script?

The setup I am using has a light-tight box enclosure to eliminate ambient light. The inside surfaces are covered in black material plus 1/2" thick layers of black foam to reduce reflections of the lasers (still not 100% successful).
The 11 white LEDS are attached to a printed bar which sits below the camera and spans across to each laser arm, where they are screwed on. This also provides additional mechanical stability for the lasers. This arrangement provides good uniform frontal illumination of the object, but is not ideal for emphasising small surface detail, as it creates a "flat" colour surface. The next step will be to add vertical light strips either side of the turntable to create a more oblique lighting angle as an optional light source.
I am currently using freelss v11 which has manual control of lighting level only. I assume that Atlas3D users with more recent s/ware have some form of closed-loop control of level.
]]>so can makerbots scanner do all that?
AFAIK the makerbot scanner does not support color or give access to the raw point cloud.

]]>STL files don't have color data, so it'd be a different file type, but yes. Also to import to 3D modeling software for say, a video game.
...or for an independent movie, CG artwork, a 3D product display, etc.
]]>The ATLAS 3D scanner can combine the laser data and the camera color data to produce full color 3D reconstructions.
Hence, lighting the object appropriately is important in order to capture full color, 3D scans like this:
but why? can it make a full color STL file for a full color 3D printer?
