Hi everyone. I'm new to this board and to making "stuff". I recently saw a video on Youtube of a device that I liked ut now I can't find it again. I'd like to know what the name of the design type is, if there is a term for it. the device was a 2D plotter where the stylus was suspended and guided by two cables that were controlled by motors on masts located on the corners of the plotters area. Moved and controlled much like the overhead cameras now used in sporting events. Could anyone here let me know what that style of device is commonly called?
