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

1. First, check if the rotary axis toggle switch is toggled to the PLATE direction.
2. If so, remove the glass cover on the left side of the engraver.
3. Remove the metal plate on top of the main board.
4. Check if LED3 of the main board is on.

Normally, LED3 will light up when the laser head returns to its origin along the Y-axis, go out, then light up again, and finally go out.

• If LED3 stays on all the time, fix the Y-axis limit (as shown) by gently tapping or replacing it.

• If LED3 does not light up, swap the X and Y motor control plugs on the main board.

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

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

1. Swap the Y1 motor plug with the X motor plug on the motor drive board (as shown).
2. Unplug Y2.
3. Check the movement of the laser head along the X and Y axes.

• If the laser head is now moving along the Y-axis but not the X-axis, replace the motor drive board with a new, identical one.
• If the laser head is moving along both the X and Y axes, replace the Y2 motor with a new identical one.
• If the laser head now is still not moving along the Y-axis,

1. Unplug Y1.
2. Plug Y2 in the X-axis drive port.
3. Check the movement of the laser head along the Y-axis.

• If the laser head is still not moving along the Y-axis, replace the rotary axis adapter plate (as shown) with a new, identical one.

•  If the laser head is now moving along both the X and Y axes, replace the Y1 motor with a new, identical one.
