A few years ago I picked up this curious electromechanical gadget at American Science and Surplus. They didn't know what it was, or where it came from.
There are no markings on it, other than the labels from the company that made the stepper motors. It has 3 steppers in an x, y and z gantry configuration with limit switch optos. Each of the 3 lead screws has a different pitch. Together they move a "nozzle" assembly.
The white part is ceramic. There is a barbed fitting for gas or fluid to this. There is also a barbed fitting to that part underneath it that resembles a showerhead. These two heads are in a fixed relation with a half-inch gap between them.
I've had this thing sitting around my office for a while, getting a lot of comments and theories as to what it might be. Maybe someone here knows?
