InkscapeFirst of all, because laser cutting is essentially a 2-dimensional process, I wanted to be able to cut out designs produced in Inkscape, the premier open-source 2D drawing application. Because our Epilog has a 24"x18" cutting surface, I created a 24"x18" document, and then I drew the lines I wished to have cut. Now, to have the lines cut (instead of raster engraved) it is necessary to make all the line widths sufficiently small (under Fill and Stroke>Stroke style>Width). I chose .001 px. Unfortunately this makes them smaller than a pixel on most screens, but don't worry, they are still there. To actually send the file to the laser cutter, in Inkscape Windows Version 0.91, choose Extensions>Export>Win32 Vector Print. This brings up the Epilog print screen. Make sure the height and width match the document, and you are ready to cut!

FreeCadAlthough Inkscape is great for quick 2D designs, for more complicated parts full 3D design software is necessary. FreeCad is starting to reach the point where it is ready for real use. After designing a part, it is easy to save an orthographic view to an svg file, then use the laser cutter to cut it out: First, select the part and go to the Drawing Workbench. From there you can create a new drawing, and add the orthographic projection. Finally, click the save drawing icon:
