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, cooling, svg, g-code, postscript and lots of other interesting techniques
For the last couple of years PhotonSaw serial number 0 has been operational at Open Space AArhus, though you have to bring your own computer and run the host-side (java) software yourself.
The current sticking point is to start to implement a simple Angularjs based UI that will allow the machine to be driven from a touch screen on an attached laptop.
The host-based software is designed to be able to import different types of files, but the best and first format implemented is SVG.
Different materials require different settings, so we try to keep a list of SuccessfulLaserSettings here.
Rough plan of attack
These are the critical main parts of the project:
- Buy the LaserSystem, 80 Watt CO2 LASER and PSU and play around with it. -Done
- Buy Optics - Done
- Build Mechanics (X/Y/Z robot and enclosure) - Done
- Build Electronics (PSUs, Stepper drivers). - Done
- Code Software (g-code interpreter, postscript-to-gcode, access control, web server) - Done'ish
- Install at OSAA (plumb into power, network and exhaust) - Done'ish
- In parallel with the actual work we're also working on PayingForItAll though sponsorships.
