REPLACING THE XY STEPPER MOTORS
Your printer’s motion system operates via two stepper motors, one in each of the two leftmost corners of the
gantry. Perform the procedure below to replace one of these motors.
Replacing a stepper motor is a process that requires small movements and finesse. Be careful not to break any
wires or other components in the printer during this process.
Note: Take care not to discard any hardware you remove during this procedure, as you will need it
during the reinstallation.
