With this joystick and a pcb your cnc mill or lathe can be controlled easily. This is an easy way to move your machine and actually see what you are doing. The jog functions in cnc software are nice, but from behind the screen of your pc the mill or lathe is too far away to actually see what you are doing. This is a nice solution to that problem. There is a free tutorial on how to make the joystick pcb on www.buildyouridea.com . In the future there will be a pic based pcb available to accompany the joystick. Still beta testing the design at the moment.
