SlideSnap Pro Modification

This is a modification to the SlideSnap Pro: https://slidesnappro.com/
At the time I bought a SlideSnap Pro, they had two models, the SlideSnap Pro, and the SlideSnap Lite. Both are based on a refurbished and modified Kodak carousel projector.
The Lite came with a Canon G-16 camera and a macro lens adaptor, the Pro came with hardware to mount a DSLR, but no camera.
I had inherited a Canon G-16 camera from my father, and was not quite sure that the G-16 had the resolution to capture all of the resolution available on a 35mm slide, so I decided to compromise. I bought the Pro, and the macro adapter lens.
I had to do a bit of tweaking to get this to work because the lite still has the lens barrel in the projector to allow the macro adapter to just slide into place, but the pro has the lens barrel removed from the projector to give the dslr a clear view of the slide.
I captured a couple of rolls of film with this setup until I got to a slide with the license plate of a car in the lowe
