This is a quick description of the PhotonSaw project and an index to the rest of the wiki.

The basic idea is to build a large 80W LASER cutter for OSAA and as a side-effect have some fun learning about mechanics, optics, stepper motors, g-code, postscript and lots of other interesting techniques.

Rough plan of attack

These are the critical main parts of the project:

1. Buy the LaserSystem, 80 Watt CO2 LASER and PSU and play around with it. -Done
2. Buy Optics
3. Build Mechanics (X/Y/Z robot and enclosure)
4. Build Electronics (PSUs, Stepper drivers).
5. Code Software (g-code interpreter, postscript-to-gcode, access control, web server)
6. Install at OSAA (plumb into power, network and exhaust)

Stretch goals

Once the critical goals have been reached there are several enhancements that could be done if we get too much funding:

1. Build a proper cutting table with a honeycomb surface.
2. Build and program an embedded Linux box to offer a web interface for management and printer server.
3. Integrate gas fire suppression (CO2 tank + release valve)
4. Nitrogen generator for assist air and fire suppression.
5. Rotating jig for engraving or cutting round objects.
