Material is deposited in a cone from a fixed point. The x and y coordinates of the apex of the cone are specified. Material is deposited in a series of cones. The stacker deposits material until it reaches a specified height. The stacker then moves a fixed distance parallel to the y axis and repeats the procedure.
Material is deposited in a series of cones.
The stacker deposits material until it reaches a specified height. The stacker then moves a fixed distance parallel to the y axis and repeats the procedure. The stacker moves parallel to the y direction while depositing material at a specified rate. The stacker remains between specified limits. Whenever the stacker reaches one of these limits, it reverses its direction of travel.
