I wrote a python script that sent G-code to step the machine in a grid via the USB-serial link, and then take photos that I later stitched with a script using OpenCV.

I think I spent more time trying to make a little tk-inter GUI for it ... that I never actually used because I all did was step in a regular grid pattern at a fixed speed... than everything else combined, and that included printing a combo ring light/lens holder-to-spindle-adapter to mount the lens in the CNC.

It was a fun single-day project. Seems like I should have started a company selling them.
