Stepper Motor Replacement

(part #’s: X-axis:12-897 Y-axis:12-898)

The X and Y axis Stepper Motors are extremely durable and should rarely require

replacement. In the event of damage to one of the motors or cables, the small motor

pulley (part # 12-829), should be replaced as well, and shipped to the customer already

mounted to the motor shaft. The motor pulley should be spaced ¾” from the motor itself.

A step ladder or stool may be needed when replacing the Y-axis (top) motor.

1) Shut down power to the machine

normally. Remove the appropriate

motor housings from the motor that

is being replaced, using either a 1/8”

Allen wrench or a 5/16” nut driver.

Remove the long, vertical housing

from the right side of the frame, and

the belt housing from the rear of the

motor mounting plate when

accessing the X-axis motor.
