1. An X-arm carriage assembly for an additive manufacturing machine, comprising:
a vertically oriented magnet frame;
a frame plate oriented vertically, parallel to and spaced from a second side of the magnet frame;
a top plate extending horizontally between the magnet frame and the frame plate, adjacent a top edge of the frame plate;
a bottom plate extending horizontally between the magnet frame and the frame plate, adjacent a bottom edge of the frame plate, parallel to and spaced from the top plate;
a first support bracket attached to a first distal end of the magnet frame and a second support bracket attached to a second distal end of the magnet frame, the first and second support bracket adapted to support the X-arm carriage assembly within an additive manufacturing machine for movement within the additive manufacturing machine along an x-axis;
an encoder strip mounted onto a first side of the magnet frame adjacent a top edge of the magnet frame and extending longitudinally along the magnet frame;
a top linear rail mounted onto the first side of the magnet frame adjacent the encoder strip and extending longitudinally along the magnet frame, and a bottom linear rail mounted onto the first side of the magnet frame adjacent a bottom edge of the magnet frame, the top linear rail and the bottom linear rail adapted to moveably support a print head carriage on the X-arm carriage assembly along a y-axis;
a longitudinal slot formed within the magnet frame between the top linear rail and the bottom linear rail; and
a linear motor magnet track mounted onto the second side of the magnet frame in alignment with the longitudinal slot and extending longitudinally along the magnet frame.
