I'm relatively new here but have been lurking for the past 6 months or so. During that time I've been digesting a lot of information I've found on here to build my own macro rig. I had a manual setup for a few months last year as I started getting into extreme macro and it wasn't long before I wanted to incorporate an Arduino.
The rail has a 1mm pitch screw and 1:2 gear reduction so with a 200 step/rotation stepper motor I get down to 0.0025mm without even micro-stepping.
Don't pay too much attention to the 10x Olympus on the Sigma 70-300 "Macro", I was just playing around with some test setups.
I was originally going to stick to an OLED and use a remote for controls but touchscreens are just easier to use. Though they take a lot longer to program! I've built a fair amount of functionality and checks and balances into the code without going too crazy. There's a lot more I could do but after 1,200 lines of code and several months work I'm satisfied for now!

Thanks!
The arms suffer from the same issue most magic arms have, if the weight on the arm is perpendicular to the screw thread in an anti-clockwise direction it's going to try unscrew itself from the plates. Aside from that they are great!
Yeah sure they're the SmallRig branded magic arms on Amazon. In fact a lot of the camera cheese plates, the riser, rods, and rod base plate are also SmallRig. They make good quality stuff for a very reasonable price.Lou Jost wrote:Besides all the neat electronic stuff, those industrial-strength magic arms caught my attention. Can you tell us where did you got them?
