Squaring the Y-Axis Actuators

Estimated time: 20–30 minutes • Skill: Intermediate

This procedure explains how to square the Y-Axis rails on 16K-series laser systems. Proper squaring ensures smooth motion, accurate engraving, and prevents premature wear on the motion system components.

Y-Axis Squaring Procedure

Power off and disconnect the machine.

Shut down the laser system and unplug the power cable to prevent accidental motion or electrical hazards during adjustment.

Figure 1: Power down and disconnect the machine.
Remove the exhaust plenum.

Using a 5/32″ Hex wrench, remove the mounting screws securing the exhaust plenum to the rear of the machine. Set the plenum and hardware aside.

Figure 2: Remove the rear exhaust plenum.
Remove the right-hand side panel.

Using a 5/32″ Hex wrench, remove the fasteners securing the right-side access panel, then carefully lift the panel away from the machine.

Loosen the front right Y-Axis actuator screws.

Using a 7/64″ Hex wrench, loosen—but do not remove—the three (3) Hex screws securing the right Y-Axis actuator to the front of the machine chassis.

These screws must remain installed to allow controlled movement during squaring.

Loosen the right-rear Y-Axis actuator screws.

Using a 7/64″ Hex wrench, loosen—but do not remove—the four (4) Hex screws securing the right Y-Axis actuator to the rear of the machine chassis.

Move the X-Axis assembly to the front of the engraver.

Carefully slide the X-Axis assembly forward until it reaches the front of the machine. Ensure the gantry is square and evenly aligned with the frame of the engraver.

Tighten the front Y-Axis actuator screws.

While holding the X-Axis assembly square, use the 7/64 ” Hex wrench to fully tighten the three (3) front mounting screws securing the right Y-Axis actuator.

Move the X-Axis assembly to the rear of the engraver.

Manually slide the X-Axis assembly toward the rear of the machine. Verify that it is square to the rear frame.

Figure 8: Position the X-Axis assembly at the rear of the machine.
Tighten the rear Y-Axis actuator screws.

Using the 7/64″ Hex wrench, fully tighten the four (4) rear mounting screws securing the right Y-Axis actuator to the chassis.
