Procedure A: Removing the Old Motor
Step 1
Unplug the engraver from its power source
Step 2
Remove both side panels.
Step 3
Remove cover on I-Beam.
Step 4
Loosen the X axis belt as follows.
1. On the left side of the I-Beam, locate the idler
pulley that the Belt wraps around. It is mounted to
a sliding plate which has two screws and a spring
attached.
2. Loosen the two Philips screws that hold the sliding
plate in place. (Do not remove the screws).
3. Push the pulley to the right hand side of the
engraver. The pulley should slide with the plate
towards the center of the machine forcing the
spring to stretch.
4. While holding the pulley to the right hand side of
the engraver, tighten the screw towards the rear of
the engraver. This will hold the pulley in place.

Step 5
Identify the Motor Assembly on the right side of the I-Beam. Locate the motor wires (red and
Black twisted wire with a black quick disconnect at the end) and disconnect them by unplugging the black
quick disconnect which is connected to the circuit board just to the rear of the motor.
Step 6
Identify and unscrew the Captive Screws which mount the motor to the I-Beam.
NOTE: The captive screws will not release from the Motor Bracket.
Step 7
Remove the motor by pulling it straight up. You may need to angle the motor slightly so that the
belt falls from the drive pulley.

Step 12
Connect the motor wires (red and black twisted wire with a black quick disconnect at the end) by
plugging the black quick disconnect in to the circuit board just to the rear of the motor.
Step 13
Connect the Fan wires by plugging the black quick disconnect in to the circuit board just to the
rear of the motor.
Step 14
On the left side of the I-beam locate the Pulley which the belt wraps around. (See Procedure A -
