Bench-top laser engraver does some cutting too

Grab that stack of old optical drives you have in the corner and get to work building this laser engraver. [Groover] is taking a no-nonsense approach to the build and we think it is just simple enough to be accessible to a very wide audience.
The physical assembly uses sleds from two optical drives. These are mounted some angle bracket. Since lasers cut at one specific focal length, there is not need for a Z axis (simplifying the build greatly). In fact, we think the hardest part of the assembly is retrieving the laser diode from a DVD-R drive and packaging it for use with this setup.
The electronics are a combination of a couple of consumer products. Two pre-fab motor drivers are used to command the stepper motors on the optical sleds. These receive their commands from an Arduino. A package called GRBL reads in G-code ([Groover] shows how to generate this from Inkscape) and in turn sends commands to the Arduino.
The results are quite remarkable. It can engrave wood with great resolution and contrast. The video after the break even shows it cutting out shapes from construction paper. Now we still want our own full-size laser cutter, but this project is much more fiscally possible for us.
