Make sure the rocker switch on the back of the ECU is on the 0 for off.

Unplug the power cord.

Disconnect the male end of the board cable from the back of the ECU by turning the locking ring and pulling gently.

Unplug the USB Cable from the back of the ECU/Driver Pack.

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.

There should be 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.

Lift the drive belt from the rail. 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.

Repeat steps 4 through 8 with the upper rail.

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.

See the instructions following for the type of Gantry Stop your machine has.

Loosen the top 3/16” stop screw of the Magnetic Gantry Stop.

Lift up the magnetic stop plate to disengage the pin from the hole and slide the alignment plate to the left end of the rail to remove.

Remove the right front 3/16” stop screw of the silver Gantry Stop Plate and set aside.

Loosen the back left T-Nut screw and slide the alignment plate to the left end of the rail to remove.

If your model only has a Stop Screw without the alignment plate, remove the stop screw.

If the shipping blocks have been misplaced, please find a way to secure the gantry so that it does not move during shipment.

Loosely place the T-Nut onto the shipping blocks and slide onto the rail on each side of the gantry. The left one is placed on the underside of the rail, and the right one is placed on the top of the rail.

Tighten into place.

Place the other two shipping blocks on the lower rail. They will be placed on the top of the bottom rail. Tighten into place.

Slide the alignment plate in from the left end of the rail and line up with the holes on the rail.

Tighten the back left T-Nut screw. Replace the right front 3/16” stop screw and tighten.

If your model only has a Stop Screw without the alignment plate, replace the stop screw.

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 screws and washers 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.

Loosen one full turn only the 3/16” Allen belt tensioner screw from the right bottom side of the lower rail marked with a red dot.

The belt tensioner should spring fully into place.

Snugly tighten the Allen belt tensioner screw on the bottom right of upper and lower rails.

Repeat these steps through with the upper rail.

Replace the two gantry covers using the two screws removed earlier.

Place the packaging foam in the bottom of the box with the cradle toward the center.

Place the head upside down into the cradle; you may need to rotate the Footblock.

Place the remaining portion of the head packaging foam across the bottom of the head and around each side; press into place.

Close and tape up the box.

Locate the packaging foam and fold out the interior feet.

Place the packaging foam on each end of the ECU/Driver Pack.

Place the ECU/Driver Pack carefully into the ECU/Driver Pack box.

Place all of the ECU/Driver Pack and emergency stop cables (if applicable) into the free space and tape shut.

Place the board box onto a table or other flat surface. Carefully place the foam corners onto the board.

With the help of a second person, carefully lift the board straight up and place it into the box.

Place the head box and the ECU box between the gantry and the side of the box between the foam corners.

Secure the board in place with additional packing material if needed.

Secure the box closed with banding or packing tape. The system is now ready to ship.
