Alden G's CNC Machine and Narrative
I have seen many builds based on the step-by-step instructions on this site, but when I see the the DIY community start to mix the ideas of one CNC machine with another, I get really excited. To take a machine and introduce concepts from another machine, like timing belt mechanics, is clever and welcome. Alden also is very creative with where he positions the drivers.
