Groover created this instructable on how to construct your own laser engraver/ cutter using two dvd players and an arduino. The two dvd stepper assemblies drive the x and y axes. The stepper motors connect to the arduino via two motor shields, and the arduino connects to your computer allowing for easy operation. The footprint is small, but it fits neatly in your workspace and it is easy to imagine adding an additional axis for routing small circuit boards!
Take hold of some means of production by making your own!
