Attaching Air Lines | 1 | 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. | Image Removed |
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. Make sure that none of the air lines are crimped. | Image Removed |
Head Installation | 1 | Move the gantry to the right edge of the CMC. Point the head so that the foot block faces toward the CMC and the wheels are close to the bottom of the gantry | Image Removed |
2 | Line up the wheels on the head to the center channels of the gantry arm and ease the head onto the gantry. | Image Removed |
3 | Roll the head up the gantry until it lines up to the head grabber arm on the right side of the gantry. NOTE: If you are installing the head and having difficulty getting the head wheels onto the gantry, see the Head Wheel Adjustment further down in this document. | Image Removed |
4 | 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 and tighten firmly. | Image Removed |
5 | Connect the air to the head by twisting the two air fittings together, matching colors. | Image Removed |
6 | Connect the head power plug (square connection) to the head grabber arm. | Image Removed |
7 | Reinstall the gantry hood, replacing the screws removed earlier. | Image Removed Image Removed |
8 | Lift the head up so that the foot block does not strike the side of the board and move the gantry Slide the Gantry Off of the Board |

Image Removed | 4 | Loosen the back left screw of T-Nut and slide the alignment plate to the left end of the rail to remove. | Image Removed |
5 | If your model only has a stop screw without the alignment plate, remove the stop screw. | Image Removed |
Slide the Gantry Off of the Board | 1 | Hold the gantry on the bottom and along the gantry arm and gently roll the gantry off the rails on the left side of the board and set aside. | Image Removed |
2 | 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. | Image Removed |
Put the Gantry on the Board | 1 | Before installation, look at the bottom set of gantry wheels. The bottom wheels are spring-loaded, the top wheels are on a center-pivot. | Image Removed |
2 | Move the top set of wheels as needed for ease of installation (picture shows gantry being put on rail from back). | Image Removed |
3 | Before installation, look at the top set of gantry wheels. Both sets of wheels are spring-loaded. | Image Removed |
4 | Wheels may need to be eased over the rails (picture shows gantry being put on rail from back). | Image Removed |
5 | Hold the gantry near the left side of the CMC and line up the upper then lower wheels of the gantry to the center channel of the rails. 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. Do not cut the tie wraps (zip-ties) on the belts until you have the Gantry on the board assembly. It is much easier not having to deal with two dangling belts. | Image Removed |
6 | Carefully ease the gantry onto the left side of the rails, taking care that all of the wheels line up. Upper and lower gantry ends must be slid on at the same time. Make sure that the drive belt lies within the channel on either side and is not pinched between the gantry and the rail. Roll the gantry to the far right of the board and back to the left to make sure it moves smoothly. | Image Removed |
Installing the Stop Plate | 1 | If you have a black Magnetic Gantry Stop Plate, slide in the alignment plate from the left end of the rail keeping the pin towards you. | Image Removed |
2 | Place the pin into the appropriate hole listed below. Tighten the top 3/16” stop screw. | Image Removed |
3 | If you have a silver Gantry Stop Plate, slide in the alignment plate from the left end of the rail so that the stop screw is on the front right. Roll the gantry so it lines up to the alignment plate. | Image Removed |
4 | Replace the 3/16” stop screw into the alignment plate. Loosely tighten the back left stop screw, then the front right stop screw, repeating until the alignment plate is secured into position. | Image Removed |
5 | If you only have the stop screw, replace the stop screw. | Image Removed |
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. | Image Removed |
2 | Remove the rubberband from the drive belt and loosely lay the drive belt along the rail channel. | Image Removed |
3 | If necessary, rotate the drive pulley so that the red mark is on the top. | Image Removed |
4 | Line up the red mark of the drive belt to the red mark of the drive pulley; this may require moving the gantry a bit in either direction. Pull drive belt to the right to take up slack. | Image Removed |
5 | Do not move the gantry after red marks line up. | Image Removed |
6 | 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. | Image Removed |
7 | Slide the screw of the belt end into the belt tensioner slot. | Image Removed |
8 | It should fit snugly. | Image Removed |
9 | Go back and make sure red lines are still lined up. | Image Removed |
10 | Remove the 5/32” Allen screws and washers from the belt tensioner. | Image Removed |
11 | Leave the gantry where it is. | Image Removed |
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. | Image Removed |
13 | 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. | Image Removed |
14 | The belt tensioner should spring fully into place. | Image Removed |
15 | Tighten the .1875” hex head belt tensioner screw. | Image Removed |
16 | Repeat steps 1 through 15 with the upper rail. |
17 | Snugly tighten the Allen belt tensioner screw on the bottom right of both the upper and lower rails. | Image Removed |
Hook Up the Gantry Air Line and Board Cable ConnectionsConnecting 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. | Image Removed |
2 | Connect the male end of the board cable to the back of the ECU by aligning the pins and turning the locking ring until it seats itself and locks into place. | Image Removed |
3 | Connect the female end of the board cable to the back of the gantry in the same manner . 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. | Image Removed |

Confirm that the the Gantry is Straight |
---|
Make sure that the Gantry is straight. Cut a rectangle that is about 2x24”, NOT cutting the outside, with 2” borders. Measure the borders to the opening at the bottom of the mat closest to the vertical clamps, then measure the borders to
|
the opening at the top of the mat closest to the vertical clamps. If the borders are not measuring 2” in both places, call Customer Support for assistance.
Image Removed | Check Gantry Wheels | 1 | Check both sets of wheels at the TOP of the gantry. | Image Removed |
2 | Make sure all of the wheels make contact with the top rail, and that they don’t spin freely. | Image Removed |
3 | If any of the wheels are not making contact, contact customer support. |
