Noisy little bugger!
Nice work. I assume the camera is only for fun, not used by the software to recognize fiducials or anything? I would like to make something like this eventually. I think I would make some code to turn a pcb component file into gcode and run the machine with mach.
Also you might look for a "vacuum ejector" made by SMC on ebay. They generate a vacuum through a venturi using compressed air. Much less annoying than the vacuum pump running.
