Mainboard Replacement for Ray5 10W / 5W

If the mainboard of your Ray5 laser engraver is faulty or needs upgrading, replacing it can restore full machine functionality. The replacement method is similar for Ray5 20W and Ray5 40W models. This example uses the Ray5 40W.

Step-by-Step Instructions

1. Use an M5 hex wrench to loosen the screws securing the control box, then remove the control box.
Make sure the machine is powered off before starting. Carefully remove the control box to access the internal components.

2. Use an M2 hex wrench to loosen the screws on the back panel of the control box and open the control box.
Remove the screws and open the back panel, keeping all screws organized for reassembly.

3. Disconnect or unscrew all cables connected to the mainboard.
Carefully disconnect each cable or terminal from the mainboard. Take note of cable positions to ensure correct reconnection later.

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.
Ensure the new mainboard is properly aligned before tightening the screws to secure it in place.

5. Reconnect the original cables to their corresponding ports (tighten as needed). The bundled cables have labels for correct placement.
Refer to the cable labels and reconnect each cable to the correct port to ensure proper functionality.

6. Close the control box, tighten the back panel screws with an M2 hex wrench, and reinstall the control box onto the machine.
Make sure all components are securely fixed before closing the control box.
