Eclipse Pro Legacy: Squaring the Gantry

Place a clean 32x40” slip sheet in the cutter.

Create a 32x40” mat with a 30x38” opening.

Slide the mat to the left until it rests halfway under the vertical clamp (do not push it all the way under the clamp). Engage the clamps.

Cut opening as usual, from the back, opening only and face down.

Draw a small X in the bottom left side of the fallout before you remove the mat from the fallout.

Open the clamps and remove the one inch mat from the fallout.

Position the fallout so the left side of the fallout is about 1” away from the vertical clamp. Draw a pencil line down the right side of the fallout, top to bottom

Turn the fallout over horizontally so the X is on the back right-hand side and the face is out.

Place the fallout to the left of the pencil line.

As you slide the fallout slowly to the right, where the fallout first contacts the original pencil line, draw a second line that will either form a parallel line or create a /\ or a / (shown exaggerated).

If you have two parallel lines, your machine is square and needs no adjustment.

Close the cut screen.

Remove the 5 bolts which hold the driveshaft cover on the left side of the machine, using 7/16” wrenches on the top and bottom.

This will expose the driveshaft.

Place a 1” piece of masking tape on the lower side of the top and bottom Gantry, across the joint between the Gantry and the X rails. Draw a vertical line on the tape and cut it at the joint. Move the Gantry to the left and right to confirm the tape placement is correct and the tape is cut in the right place.

If the / that was created in Step 10 is with the point up, you will need to move the bottom Gantry to the left by one half the width of the / at its widest point, or to the right if the point is down.

The squaring adjustment on the driveshaft is held in place by two couplings, one at the top of the driveshaft, the other toward the bottom; the bottom coupling is the one we will adjust. The top half of the lower coupling may have either one or two 1/8” Allen set screws. Loosen these Allen screws.

Align the top masking tape line on center. Holding the driveshaft still, move the bottom line either left or right as required by rotating the coupling.

Retighten the Allen screws.

Example: If the point of the / is down, and the width of the / at its widest point is one quarter inch, then the bottom Gantry needs to be moved to the right 1/8”.

Do another test cut and see if it needs to be readjusted.
