3) Software for Gcode generation
The Cyclone project supports only free software (free as in freedom). Here is a list of the recommended solutions:
JScut is a lightweight browser-based CAM to generate gcode from vector image files (SVG). It includes a 3D tool-path simulator.
Example: Mill the OSWH keychain
FlatCAM is a gcode generator that takes Gerber/drill files. Very useful for the manufacture of printed circuit boards (PCBs).
Example: Mill a stereo audio amplifier (load the included project file)
Blender CAM is a powerful software that generates gcode from STL 3D files.
