In May 2011 an article about a DIY motion control caught my attention. I was especially interested to try it with the Dragonframe software. I followed the idea of Martin Koch but replaced the wire with a steel threaded rod and two nuts, to make it more suitable and reliable for stop motion animation.
Because I was working on other things as well I only started ordering the materials in 2013. After assembling everything, the rail movement worked when testing a few scripts, but I couldn't control it with Dragonframe.
Now, after two years (and again, working on other things), I decided to give the prototype another go. And for some reason it works! I uploaded the provided script (without the kill switch line in the code) and the Arduino Uno connects and works perfectly with Dragonframe :)
I made a little video to show you the MC in action!
I'll do some more tests later to find out how well it can return to it's original position and such.
