X-Y stage for film scanner Answered
I'm building a film scanner using a dlsr.
Here's a picture of the rig so far:
Basically there's a light source, negative stage, negative holder, camera support stage, camera and lens. I put a negative in the negative holder and slide it using a guide such that I can take a bunch of pictures of the negative at 1:1. For example, it takes 25 pictures to cover a 6x7cm negative. The individual files are then combined into one file using stitching software.
The system works very well, but it's a bit tedious. I'd like to automate the negative movement using a diy motorized xy stage. Many of the designs I've seen are for much bigger units, such as for a cnc machine, or units that require speedy movement. That's not the case here. Each movement would be only 10-20mm.
I'm fairly handy, and I can follow directions/recipes well, but I haven't worked with arduinos or stepper motors before. Any advice or suggestions on a good way to accomplish my goal would be very welcome!
