The screen on top displays an image of the path the bit needs to follow. The user runs it like a normal router, and as the router moves, the path on the screen moves too. The user needs to keep the router bit roughly close to the path and follow the line on the screen. The spindle of the router has X and Y movement within an inch or so in the body of the tool, and compensates for the user's rough movementto create the correct cut that was programed.I'm too dense and missing the concept. What is moving the machine - the operator or little drive wheels or ??
I was about to start comparing it to the Festool routers when I saw that Festool designed the spindle and Festool's parent company now owns Shaper. I bet it's a costly part replacement - little different than a $100 Colt from whatever store down the street to keep your run-of-the-mill CNC going.
