Disconnect Gantry1. Disconnect the air lines to the gantry by untwisting the air fittings (Fig A). 2. Disconnect the board cable by turning the locking ring until it comes away from the gantry.

Fig A.

Removing the Toothed Belt from the Rail

Look for Red Dots (only these screws are to be ad-justed).

1. Loosen one full turn only the 3/16” Allen belt tensioner screw located on the right bottom side of the lower rail marked with a red dot (Fig A). Only loosen it so that there is some movement in the belt tensioner; about one full turn (Fig B). Belt tensioner springs should be visible.

WARNING: Do not over loosen this screw. One full turn is usually sufficient.

Fig A. Fig B.



2. Locate the belt tensioner hole on the end of the belt tensioner (Fig C). Place the 5/32” Allen screw and washer we re-moved from the lower gantry plate into the belt tensioner hole (Fig D). Tighten the Allen screw until belt tensioner is flush with the rail and the springs are not visible. 3. Go back and tighten the 3/16” Allen belt tensioner screw on the right bottom side of the lower rail marked with a red dot (Fig E).

Fig C. Fig D. Fig E.

4. Lift the toothed belt end (Fig F) out of the belt tensioner slot (Fig G). Pushing the toothed belt end to the right may assist in getting a hold of it. Wind up the toothed belt, and rubberband it (Fig H).

Fig F. Fig G. Fig H.

5. Repeat steps 1 through 4 with the upper rail.

Slide off Gantry1. Move the gantry to the left to dislodge the belt anchors (Fig A). The belt anchors are sunk into the left ends of the rails and are attached to the toothed belts. Lay the belt anchors over the toothed belts and rubberband them together.2. Hold the gantry on the bottom and along the gantry arm (Fig B) and gently roll the gantry off the rails on the left side of the board and set aside (Fig C). The gantry only weights about 30 lbs, but it is large and awkward, so having a second person standing in front of the CMC helping may be beneficial.




Gantry Installation

Put the Gantry on the Board1. Before installation, look at the bottom set of gantry wheels. The bottom wheels are spring-loaded, the top wheels are on a center-pivot (Fig A). Move the top set of wheels as needed for ease of installation (picture shows gantry being put on rail from back) (Fig B).

Fig A. Fig B.

2. Before installation, look at the top set of gantry wheels. Both sets of wheels are spring-loaded (Fig C). Wheels may need to be eased over the rails (picture shows gantry being put on rail from back) (Fig D).

Fig C. Fig D.

3. Hold the gantry near the left side of the CMC and line up the upper then lower wheels of the gantry to the center chan-nel of the rails (Fig E). NOTE: Installation is easier if you line up the upper wheels first, then slide the lower wheels onto the rail. Sometimes having a second person for this step helps.4. Carefully ease the gantry onto the left side of the rails, taking care that all of the wheels line up. Upper and lower gan-try ends must be slid on at the same time. Make sure that the toothed belt lies within the channel on either side and is not pinched between the gantry and the rail (Fig F). 5. Roll gantry past where the stop screw was removed. Replace the 3/16” stop screw into the left bottom rail (Fig G). Roll the gantry to the far right of the CMC and back to the left to make sure it moves smoothly.




Installing the Toothed Belt onto the Rail1. Lightly pull the coiled toothed belt toward the right to take up the slack and pull the belt anchor into place flush with the end of the CMC (Fig A). Loosely lay the toothed belt along the rail channel (Fig B).

Fig A. Fig B.

2. If necessary, rotate the toothed pulley so that the red mark is on the top (Fig C). Line up the red mark of the toothed belt to the red mark of the toothed pulley; this may require moving the gantry a bit in either direction (Fig D). Pull toothed belt to the right to take up slack (Fig E). Do not move the gantry after red marks line up.

Fig C. Fig D. Fig E.

3. Remove the rubberband from the toothed belt and pull the loose belt end to the right, making sure that the toothed belt is not twisted and that the teeth are facing down toward the board into the rail channel (Fig F). Slide the screw of the belt end (Fig G) into the belt tensioner slot (Fig H). Go back and make sure red lines are still lined up.

Fig F. Fig G. Fig H.



4. Remove the 5/32” Allen screws and washers from the belt tensioner (Fig I and J). Place the two Allen screw and washer into the holes provided on the lower gantry plate (Fig K). Place them so that the screw protrudes only slightly from the back of the plate.Leave the gantry where it is.

Fig I. Fig J. Fig K.

5. 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 (Fig L). The belt tensioner should spring fully into place (Fig M).

WARNING: Make sure you do not over loosen this screw. One full turn is usually sufficient.

Fig L. Fig M.

6. Repeat steps 1 through 5 with the upper rail.7. Go back and snugly tighten the 3/16” Allen belt tensioner screw from the right bottom side of the lower rail and the right bottom side of the upper rail marked with a red dot (Fig N).8. Continue with “Hook up the Gantry”.

Fig N.



Hook Up the Gantry

Connecting the Board Cable

*Carefully align the in-line pins of the board cable before applying pressure to plug it in. If forced in incorrectly, the CMC will malfunction.*

1. The board cable connects the gantry on the CMC to the ECU, which is a shoebox-sized peripheral. Connect the male end of the board cable (Fig A) to the back of the ECU (Fig B) by aligning the pins and turning the locking ring until it seats itself and locks into place. 2. Connect the female end of the board cable to the back of the gantry in the same manner (Fig C). 3. Move the gantry to the far right of the CMC and back to the left to make sure the board cable does not get caught on anything. If the board cable is obstructed, this will affect the cuts.


Attaching Air Lines1. Follow the air line with the red connector from the top of the gantry and connect it to the right side of the air regulator by inserting the red connector on the end and twisting it into place (Fig A).2. Follow the air line with the blue connector from the top of the gantry and connect it to the matching blue airline on the back of the board (Fig B). Make sure that none of the air lines are crimped.3. Turn on the air.

Fig A. Fig B.



* CAUTION: The air regulator is factory-set. Do not make adjustments to it.*

Head Installation1. Move the gantry to the right edge of the CMC. 2. Point the replacement head so that the foot block faces toward the CMC and the wheels are close to the bottom of the gantry (Fig A). 3. Line up the wheels on the head to the center channels of the gantry arm and ease the head onto the gantry (Fig B). 4. Roll the head up the gantry until it lines up to the head grabber arm on the right side of the gantry (Fig C).NOTE: If you are installing the head and having difficulty getting the head wheels onto the gantry, see “Head Wheel Adjustment”.


5. Holding the head in position so that the head lines up neatly to the head grabber arm, replace the two 5/32” screws, making sure they go into the head grabber arm and into the head (Fig D) and tighten firmly. 6. Connect the air to the head by twisting the two air fittings together, matching colors (Fig E). 7. Connect the head power plug (square connection) to the head grabber arm (Fig F). 8. Reinstall the gantry hood, replacing the screws removed earlier (Fig G).9. Lift the head up so that the foot block does not strike the side of the board (Fig H) and move the gantry to the left. Turn on the air.

Fig D. Fig E. Fig F. Fig G. Fig H.

10. The head is installed. IMPORTANT: PROCEED TO HEAD WHEEL ADJUSTMENT INSTRUC-TIONS.



Head Wheel Adjustment

WARNING: To avoid damage to the head, do not loosen the head wheel screws without first aligning the head to the middle of the board.

1. Go to the cut preview screen. Manually move the head and the gantry to the middle of the board, and click the power button (Fig A) and align the head in this position (Fig B).

Fig A. Fig B.

2. Locate the head wheel adjustment Allen screws on the left side of the head under the blade depth adjustment plate. They are next to the head wheels and are marked with red dots. Do not touch the Allen screws on the wheels themselves.3. Loosen each head wheel adjustment Allen screw only until the wheels are loose; about two full turns (Fig C). The wheels are spring-loaded and will pop into place. NOTE: If having difficulty getting the head wheels onto the gantry during head installation, loosen the head wheel adjust-ment screws, roll the head onto the gantry, then continue with the following instructions.4. Grasp the head with both hands and gently rock it back and forth to ensure that the wheels are lined up to the gantry grooves (Fig D).

Fig C. Fig D.



5. Retighten the head wheel adjustment Allen screws consecutively; tighten the top screw half a turn, then the bottom screw half a turn, back to the top and continue until they are both tight (Fig E). 6. Check each of the head wheels to make sure there is no movement (Fig F). There are the two visible wheels on the left side of the head under the blade depth adjustment plate, and two wheels on the backside of the gantry, which can be felt by hand. They should sit firmly into the gantry groove and be difficult to turn. If not, repeat these steps of loosening the wheels, gently rocking the head back and forth (Fig G), then retightening the wheels.


7. The head wheels have now been adjusted. Click on the reset motors button (Fig H), click ok on the reset motors screen if it displays and return the head to the home position (Fig I-J). Reinstall the blade cartridge if necessary.
