* Cutting materials - cutter speeds and feed rates - dependent on what you want to cut. Some things (i.e. wax, modeling board) are very forgiving, while others (particularly metals) need to be just right for good results. | * Cutting materials - cutter speeds and feed rates - dependent on what you want to cut.

* 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). | * Any CAM package, Fusion 360 is a good one if you are not sure.
