Assemble the Boxes

  • Remove the CMC box marked “bottom” from the shipped package and unfold it onto a flat surface.

  • An area of at least 8’ x 10’ is needed to assemble the box.

  • Make sure that the printed side of the box is face-down, toward the floor.

  • Pre-fold the sides of the box to make assembly easier.

  • Carefully peel back the adhesive paper from one corner flap and affix the corner flap to the inside edge of the box side.

  • NOTE: Take care that the adhesive does not touch any other surface other than the inside edge of the box side. The adhesive could become contaminated or pull away from the box surface.

  • Press the corner flap firmly into the inside edge of the box to make sure it has made strong contact.

  • The corner is assembled.

  • Repeat the Steps above on the other three corners.

  • Repeat the Steps above on the CMC Box marked “Top”.

Loosen Drive Belt

  • Remove the gantry cover by unscrewing the screws that holds it in place and set them aside.

  • Move the gantry to the right side of the board about two feet from the right edge (to leave room for the packaging foam corners).
