I'm working on the CAM workbench (Path) for the open source software FreeCAD . Path is still pretty young but able to do some interesting 2.5D work already.
Anyway, I'm interested in writing a post processor for a Busellato Jet 3006 router but I don't know much about these machines. I'm looking for a gcode reference or other documentation to help me.

If anyone has a link or knows about other open source posts that I can study, I'd be grateful.
