If the laser head won’t return to its origin along the X-axis after being powered up.

1. Remove the glass cover on the left side of the engraver and then remove the metal plate above the mainboard.
2. Check whether the LED1 of the mainboard is on.

Under normal circumstances, LED1 will light up after the X-axis has been reset to its origin, go out, then light up again, and finally go out.

• If LED1 stays on all the time, fix the X-axis limit (as shown) by gently tapping it or replacing it.

• If LED1 does not light up, swap the X and Y motor control plugs on the main board.

If the laser head is moving along the X-axis but not along the Y-axis, the mainboard is faulty. Replace it with a new identical one.

If the laser head remains inactive along the X-axis, Remove the bottom plate.

Swap the X motor plug with the Z motor plug on the motor drive board (as shown).

1. Power off the engraver.
2. Manually move the laser head to the lowest point along the Z-axis by turning the Z-axis screw.
3. Turn on the engraver again and check the movement of the laser head along the X-axis and Z-axis.
4. If the laser head is moving along the X-axis but not the Z-axis, replace the motor drive board with a new, identical one.
5. If the laser head still does not move along the X-axis, replace the X-axis motor with a new, identical one.
