Franklin Griffin
I just found out that a former co-worker of mine, Franklin Griffin, has got in touch with Open Source Ecology. Hey Franklin! He built a cnc plasma cutter about 10years ago that worked very well. Franklin has inspired me by accomplishing some incredible things with his work. I wanted to let you know just in case he might be able to answer some questions for you or Anthony along the way, or something like that.
