Grumpy_Mike,
I stumbled across your design actually and liked it. I believe that it might work well. What did you use for the transfer of G-code, I don't remember seeing a USB interface. I am also on my phone so it is hard to navigate. Are those homemade Arduinos and a single pololu driver? I saw a circuit diagram so when I get home I'll exam it a bit more closely. I like the idea of the display and everything, looks nice and clean. I am a little worried about going outside my abilities at the beginning. I can follow a schematic well enough so could probably build it with a little help. Did it work well for you, the coil you machined looked quite good? What did you use to generate the G-code?
If I built the Reprap design would it allow me to use a version of software already developed? It is a fairly inexpensive design other than the mega. My main goal is attempt to use an Arduino UNO for the cost savings over the mega. Anything I use would be well documented for sharing. We will likely build a site to share everything and possible sell machined parts required for the build. If we sold machined parts it would allow those with few tools or access to precision machines to build at home.
As for location I am not in Indy. IUPUI is a satellite campus in Indy and I attend at the main campus in West Lafayette.
