Replacing the Mainboard

The replacement method is similar for Ray5 20W and Ray5 40W. This example uses the Ray5 40W.

1. Use an M5 hex wrench to loosen the screws securing the control box, then remove the control box.

2. Use an M2 hex wrench to loosen the screws on the back panel of the control box and open the control box.

3. Disconnect or unscrew all cables connected to the mainboard.

4. Use an M2.5 hex wrench to loosen the screws securing the mainboard, remove the old mainboard, and install the new mainboard. Secure it with the original screws using the M2.5 hex wrench.

5. Reconnect the original cables to their corresponding ports (tighten as needed). The bundled cables have labels for correct placement.

6. Close the control box, tighten the back panel screws with an M2 hex wrench, and reinstall the control box onto the machine.

Replacement complete.
