			Using a CNC requires a bit more background knowledge or learning than a laser cutter or 3d printer. You should have some knowledge of CAD and CAM concepts and have used a CAD/CAM or other package capable of generating g-code for CNC machining.

+* The difference between CAD geometry files (i.e. DXF, IGES and STEP), and tool path files (i.e. G-Code)
+* Cutting materials – cutter speeds and feed rates – dependent on what you want to cut. There are many examples posted by Shapeoko users as a starting point.
-If you can't attend your induction session please remove your name from the roster.
+* Any CAM package, Fusion 360 is a good one if you are not sure. You should try generating a tool path with a particular cutter, checking the toolpath visually and by simulation if your CAM software allows it, and finally posting the G-Code to the a g-code file (i.e. .gcode extension).
 * XYZ coordinate systems (on the Shapeoko, x is left to right (+x is travelling right), y is towards / away from you (+y is travelling away from you), and z is down / up (+z is travelling up)
