G-code Basics

Learn the language machines speak. You move a real CNC router in 3D, write your first G-code, change it and watch it cut, work out a safe speed, cut circles, cut right through a sheet, read a real program, fix a bug, and meet the laser and the 3D printer. Every program runs in 3D as you edit it. For anyone 13 and up. Free.
