DIY CO2 Laser CNC Table

Owen White bought a Coherent G100 100 Watt CO2 laser on eBay and decided to create his own CNC table. He chronicled his construction project in his blog. He is now using his DIY CNC table to cut all sorts of things. Owen writes, "Your readers might be interested in the documentation on the computer controlled circuitry to run the CNC table and laser. For circuit prototyping I used some conventional off-the-shelf electronics packages to design the circuits, then mapped the net diagrams from the circuit software to locations on a wire-wrap board using some perl code. This simplified the process of staring at a circuit and deciding where wire-wrap connections should be made. Prototype PCBs were also made. I used AVR microcontrollers for a couple functions."
