The gantry moves the head in the X and Y directions when building a part. The gantry
assembly is located under the top cover. The entire gantry is outside of the oven; only the
bottom of the head protrudes into the oven. The gantry and its drive motors are thermally
shielded from the oven via flexible heat shields (oven bellows). Two directly-coupled, X-linear
motors and one Y servo motor, which is attached to a timing belts.
