Ben, very nice, obviously some more work needed, but a bit of fiddling never went astray.

I run stepper motors on my LASER and they have the ability to step in 1/1200" increments. This means that the beam is moved around in a stepless or seamless fashion, so to speak.

Going on my experience with a friend and the aforementioned rotating camera, try a faster rotation and a bigger slit opening for less banding. If you can of course!

Mick.
