== Gnerating g-code from your designs == | |||
There are a lot of different options for preparing a g-code file which can be loaded onto the CNC to cut a design. Some examples of free software include; | |||
2D Packages | |||
* MakerCam (Free) http://www.makercam.com/makercam.swf | |||
* Cambam (LHS has a license, installed on the Robotics laptop) http://www.cambam.info/ | |||
3D Packages | |||
* Autodesk Fusion 360 (Free for non-commercial use, Windows / OSX) http://www.autodesk.co.uk/products/fusion-360/overview | |||
When using Fusion 360, in order to post to the Hackspace CNC machines, the Generic EMC2 post-processor should be selected when finally saving the g-code file. LinuxCNC recognises the "ngc" file extension although any extension can be used. | |||
