I put pen to paper just 19 days ago. It has progressed faster than I would have ever dreamed. I would have posted more here but I didn't even know about this until a few days ago.
I teach at a residential high school in Arkansas for gifted students. I had one of my students work on a 1-arm SCARA mockup that has been bouncing around in my brain since the first time I saw a RepRap Morgan.
The results where more than promising. We quickly started making plans to turn it into a 3D printer. My intention was to bring my student along on the design journey but I was a dog with a bone and I could now see what this could be. I cranked up AutoDesk Inventor and quickly cranked out this.
I ordered all the vitamins and started printing all parts. I quickly got a functional arm together.
I then set to work on making the firmware take care of the kinematics. Shortly thereafter, printing!
I have taken it so much further than this but I think this is a good place to wrap up the first post.
