When to Replace the Motors:

1. The motor is damaged, and it cannot move or moves unsmoothly, making a cracking sound that affects normal operation.

 

X-axis Motor Replacement:

Disassembly:

1. Turn off the printer.
2. Remove the front shell of the printer's right shoulder pendant and use a 2.0mm wrench to unscrew the two fixing bolts of the right shoulder back shell. Remove the back shell.

 

3. Use a 2.5mm wrench to loosen the X-axis belt and pull it out from the extruder V-wheel fixing bracket and the X-axis synchronous wheel.

4. Unplug the power terminal of the X-axis motor.

5. Use a 2.0mm wrench to unscrew the four fixing bolts of the X-axis motor and remove the motor.

Installation:

1. Install the new X-axis motor and use a 2.0mm wrench to tighten the four fixing bolts.
2. Insert the X-axis motor power terminal.
3. Thread the X-axis belt onto the X-axis motor synchronous wheel and insert it into the X-axis belt adjustment space of the left shoulder. Use a 2.5mm wrench to adjust the belt to the appropriate tightness.
4. Reattach the right shoulder shell and tighten the two fixing bolts of the right shoulder shell with a 2.0mm wrench.
5. Turn on the printer, connect the mobile app, and enter the device > Move menu to check the X-axis movement.

5. Ensure the X-axis moves smoothly without any abnormal noise to complete the replacement.

 

Y-axis Motor Replacement:

Disassembly:

1. Turn off the device and unplug the power cord.
2. Remove the cover plate on the base and pull out the two Z-axis motor terminals.

3. Use a 2.5mm wrench to unscrew the 4 foot pad fixing bolts and the 5 bottom case fixing bolts, then remove the printer bottom case.

4. Unplug the Y-axis motor terminal.

5. Use a 3.0mm wrench to loosen the Y-axis belt adjustment screws and remove the belt from the Y-axis motor synchronous wheel.

6. Use a 2.0mm wrench to unscrew the Y-axis motor fixing bolt and remove the motor.

Installation:

1. Install the new Y-axis motor and align it with the bolt hole. Use a 2.0mm wrench to tighten the fixing bolt.
2. Place the belt on the Y-axis synchronous wheel and use a 3.0mm wrench to tighten the belt adjustment screws.
3. Insert the Y-axis motor terminal.
4. Reattach the bottom shell and use a 2.5mm wrench to tighten the 4 foot pad fixing bolts and the 5 bottom shell fixing bolts.
5. Insert the two Z-axis motor terminals and cover the base plate.
6. Plug in the power cord, turn on the device, connect the app, and move the Y-axis to ensure smooth operation.

 

Z-axis Motor Replacement:

Disassembly:

1. Turn off the printer and unplug the nozzle assembly cable at the base end.

2. Flip the printer back and remove the base cover.

3. Unplug the Z-axis motor terminal.

4. Use a 4.0mm wrench to unscrew the 8 gantry fixing bolts.

5. Remove the gantry.

6. Use a 2.0mm wrench to unscrew the two fixing bolts (one on each side) between the Z-axis motor fixing bracket and the gantry.

7. Pull down the Z-axis to separate the motor from the gantry, then use a 2.5mm wrench to unscrew the locking bolt of the Z-axis motor coupling and remove the motor.

8. Use a 2.0mm wrench to unscrew the four fixing bolts between the Z-axis motor and the fixing bracket, then remove the motor.

Installation:

1. Use a 2.0mm wrench to lock the four fixing bolts between the Z-axis motor and the fixing bracket.
2. Place the coupling on the motor bearing and use a 2.5mm wrench to tighten the Z-axis motor coupling locking bolt.
3. Use a 2.0mm wrench to tighten the two fixing bolts (one on each side) between the Z-axis motor fixing bracket and the gantry.
4. Insert the gantry into the printer base.
5. Flip the printer back and use a 4.0mm wrench to tighten the gantry and base fixing bolts.
6. Insert the Z-axis motor terminal.
7. Cover the printer base and stand up the printer.
8. Plug in the nozzle assembly cable at the base end.
9. Turn on the power, move the Z-axis, and ensure smooth operation to complete the replacement.
