Cautions | |
|---|---|
NEVER SKIP AHEAD ON ANY STEP! Head appearance may vary from model shown, but the connections are the same. Never pull/push on the drive shaft to move the gantry. Use the gantry arm to move/pick up the gantry. | |
Do not pick up the head using only the blade depth knob or the head cover. Pick up the head by holding the “D-Shaped” upper and lower head plates. | |

Head Removal | |
|---|---|
Click reset motors button on the cut preview and click OK on the release motors prompt. | |
Push blade cartridge release down to eject the blade cartridge. Turn off the air. | |
Remove the hood from the gantry by unscrewing the screws that holds it in place and set aside. | |
Move the gantry to the right side of the board until the foot block is off the board. | |
Disconnect the head power plug (square connection) from the head grabber arm. | |
Disconnect the air to the head by untwisting the two air fittings. | |

NEVER SKIP AHEAD ON ANY STEP! |
Remove Stop Screws | |
|---|---|
Remove the front right 3/16” stop screw from the alignment plate on the left bottom rail (located on the top of the bottom rail) and set aside. | |
Loosen the back left screw and T-Nut and slide the alignment plate to the end of the rail to remove. If your model only has a stop screw without the alignment plate, remove the stop screw. | |
Remove the 5/32” Allen screws and washers from the lower gantry plate. | |

Removing the Drive Belt from the Rail | ||
|---|---|---|
| 1 | Look for Red Dots (only these screws are to be adjusted). | |
| 2 | 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. Only loosen it enough so that there is some movement in the belt tensioner; about one full turn. WARNING: Make sure you do not over loosen this screw. One full turn is usually sufficient. | |
| 3 | Belt tensioner springs should be visible. | |
| 4 | Locate the belt tensioner hole on the end of the belt tensioner. | |
| 5 | 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. | |
| 6 | 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. | |
| 7 | Lift the drive belt end out of the belt tensioner slot. | |
| 8 | Pushing the drive belt end to the right may assist in getting a hold of it. | |
| 9 | Wind up the drive belt, and rubberband it. | |
| 10 | Repeat steps 1 through 9 with the upper rail. | |
...
Installing the Drive Belt onto the Rail | ||
|---|---|---|
| 1 | 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. | |
| 2 | Loosely lay the drive belt along the rail channel. | |
| 3 | If necessary, rotate the alignment pulley so that the red mark is on the top. | |
| 4 | Line up the red mark of the drive belt to the red mark of the alignment pulley; this may require moving the gantry a bit in either direction. | |
| 5 | Pull drive belt to the right to take up slack. Do not move the gantry after red marks line up. | |
| 6 | Remove the rubberband from the drive belt and 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. | |
| 7 | Slide the screw of the belt end into the belt tensioner slot. Go back and make sure red lines are still lined up. | |
| 8 | The screw of the belt end snaps into the belt tensioner slot. | |
| 9 | Remove the 5/32” Allen screws and washers from the belt tensioner. Leave the gantry where it is. | |
| 10 | 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. WARNING: Make sure you do not over loosen this screw. One full turn is usually sufficient. | |
| 11 | The belt tensioner should spring fully into place. Repeat steps 1 through 10 with the upper rail. | |
| 12 | 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. | |
| 13 | 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. | |
