I couldn't get the machine to do a carving on a 11inchx6 foot board because it always wanted to start the carving near the wrong end of the board. I finally realized I set the end of the carving at 3 1/2 from the finish end of x axis. The machine needs an arm to reach out and slap someone who does what I did. I think it would be a big help to stop people doing stupid stuff?
