2. Find the Y-axis stepper motor, referred to as the Y-motor or stepper motor. The Y-motor is the one furthest away from the Extruder Adapter Board.

Figure 2 Find the Y motor.


3. Unplug the Y motor cable.

Figure 3 Unplug the Y motor cable.


4. Use a 1.5mm hex wrench to loosen the 4 securing screws on the Y-axis grooved coupler, referred to as Y-axis coupler or Y-coupler.

Note: There is no need to remove the securing screw. Hold the Y-motor.

Figure 4 Loosen the 4 securing screws on the Y-coupler.


5. Use a 3mm hex wrench to remove the 4 securing screws securing the Y-motor bracket.

Note:

1. When removing the securing screw, hold the Y-motor to prevent the motor from falling and damaging the Y-coupler.

6. Move the coupler with your finger. Then remove the Y-motor and coupler as a whole.

Note: Hold the stepper motor when moving the coupler.

Figure 6 Remove the Y motor and coupler as a whole.


7. Place the Y motor and coupler on a flat table, and remove the coupler.

Figure 7 Remove the coupler.


8. Use a 3mm hex wrench to remove 4 screws on the bracket. You will get an X-axis stepper motor and a stepper motor bracket.

Figure 8 Remove the bracket.


D. Install a new Y-axis motor

1. Prepare a new Y-axis motor. Use a 3mm hex wrench to fix the stepper motor on the stepper motor bracket.

Figure 1 Install the motor.


2. Insert the coupler on the shaft of the Y-motor, and insert the other end of the coupler on the Y-axis.

Warning: Make sure that the plane of the shaft of the ①Y motor,②③the two screws on the coupler, and ④the plane of the Y-axis are aligned.

Figure 2 Insert the coupler back on the shaft of the Y motor and back to the Y axis.


Figure 3 Make sure all the four parts mentioned are aligned.


3. Use a 3mm hex wrench to install the 4 securing screws on the Y-motor bracket to the printer, but do not tighten the them.

Figure 4 Install 4 securing screws, but not tighten them.


4. Hold the Y-motor with one hand, and finely rotate to adjust the position of the coupler with the other hand. Check that the Y-motor, Y-axis coupler and Y-axis are aligned. After the three are aligned, move the Y-coupler until it can move back and forth smoothly.

Figure 5 Finely rotate to adjust the position of the coupler.


Warning:

1. This step is very important. Make sure that the Y coupler can move smoothly. If it does not move smoothly, the three are not aligned. Adjust the position of the Y-motor and Y-coupler until the coupler can move smoothly.

2. If the Y-motor cannot be moved, slightly loosen the four Y-axis bracket securing screws.

3. Please move the coupler slightly to avoid bending it.


5. When the coupler can move back and forth smoothly, tighten the 4 screws on the bracket with a 3mm hex wrench.

Note: Tighten the screws in diagonal order.
