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.

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”.

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).

Remove the 5/32” Allen screws and washers from the lower gantry plate.

Locate the 3/16” Allen belt tensioner screw that’s located on the right bottom side of the lower rail and marked with a red dot.

Loosen this screw one turn only so that there is some movement in the belt tensioner.

The tensioner springs should be visible.

Locate the belt tensioner hole on the end of the belt tensioner.

Place the 5/32” Allen screw and washer we removed from the lower gantry plate into the belt tensioner hole.

Tighten the Allen screw until belt tensioner is flush with the rail and the springs are not visible.

Go back and tighten the 3/16” Allen belt tensioner screw.

Pushing the drive belt end to the right may assist in getting a hold of it.

Wind up the drive belt, and rubber-band it.

Move the gantry far enough to the left to dislodge the belt anchors.

The belt anchors are sunk into the left ends of the rails and are attached to the drive belts.

Lightly pull the coiled drive belt toward the right to take up the slack and pull the belt anchor into place flush with the end of the CMC.

Remove the rubber-band from the drive belt and loosely lay the drive belt along the rail channel.

Pull the loose belt end to the right, making sure that the drive belt is not twisted and that the teeth are facing down toward the board into the rail channel.

Slide the screw of the belt end into the belt tensioner slot.

Remove the 5/32” Allen screw and washer from the belt tensioner.

Place the two Allen screw and washer into the holes provided on the lower gantry plate.

Place them so that the screw protrudes only slightly from the back of the plate.

Fold and separate the middle top and middle bottom foam corners from each other.

Attach the bottom left, middle and bottom right foam corners.

Attach the wider top left, middle and top right foam corners.

For the model 5000, remove the insert before placing over the motors on the board.

Place the bottom board box (marked BT) onto a table or other flat surface.
