Project: Laserscythe - Another Open Source laser engraver using recycled doohickeys

This project is basically a laser engraver frame designed to work with leftover TAZ 3d printer pieces and whatever stuff I had laying around. It should be pretty easy to adapt to whatever size or bearing setup you would like to use. The electronics setup is a clone of villamany’s 3dPburner project (http://3dpburner.blogspot.com/ - http://www.thingiverse.com/thing:610934 ), the only real differences are the 3d printed frame and parts. I wanted to go a different direction with most of the pieces, and I wanted to ensure they were all truly available as open source, so I ended up making my own parts.
This is the first laser I have made or designed, so there may be some tuning required. It seems to work ok so far though!
