The gantry is the frame that supports the end effector and has the components moved by the
stepper motors to create motion of the end effector. The basis of the CNC in this application
is a two-axis gantry made of extruded aluminum rails. A cable track is used to route the wires
to prevent tangling in the machine, as shown in Figure 2-1.
