The image below shows all the components of the motion system. The red components are part of the vertical axis of the machine, they are responsible for supporting the guides for the horizontal axis. The blue elements are part of the horizontal axis of the machine, they provide the guides for the product dispenser motor. The yellow element in the picture is the carrier of the product dispenser motor, that will be moved by another motor to engage the coupler with the product dispenser.
