The Form Cure L V2 motherboard is mounted to the back of the machine’s display assembly. If the motherboard is faulty or malfunctioning, the Form Cure L V2 may behave erratically or not function at all.

Use this guide to replace the motherboard on a Form Cure L V2.

Tempo stimato: 15–20 minuti

Overview: Prepare the Form Cure L V2 and workspace for replacing the motherboard.

Step 1: Prepare the workspace

Clear a workspace around your machine. Ensure that the workspace is well-ventilated and free of dust.

Step 2: Unplug the machine

Turn off the machine using the power switch on the back of the unit. Disconnect the power cable before continuing with maintenance. Do not perform maintenance on the machine while it is connected to power. Wait five minutes after disconnecting the machine from power before proceeding. If the machine was recently in use, the post-cure chamber will be warm. Wait at least 10 minutes for the chamber to cool.

Overview: Disconnect and remove the original motherboard.

3° passaggio: smontaggio della scheda madre e del gruppo display

Inclina delicatamente la scheda madre e il display verso l'alto, quindi tirali verso il basso. L'assemblaggio dovrebbe staccarsi dal telaio dell'apparecchio. Non tirare con forza il gruppo scheda madre e display, poiché è ancora collegato alla Form Cure L V2 da un set di cavi.

4° passaggio: scollegamento dei cavi della scheda madre

Disconnect all of the cables from the motherboard except for the two ribbon cables. For each, squeeze the tab and slide the cable out of the connector. Take care not to pull on the wires themselves.

Fully separate the motherboard and display assembly from the machine and set it display-side down on your work surface.

Step 5: Uninstall the motherboard

Disconnect the two ribbon cables from the side of the motherboard. For both, slide the black latch on the cable connector away from the white connector body. Once the latch is open, the ribbon cable should separate from the connector with minimal force. Take care not to fold or otherwise damage the ribbon cables.

Using a Phillips driver, loosen and remove the five screws securing the motherboard to the display assembly. Set the screws aside.

Fully separate the motherboard from the display assembly and set it aside for disposal with electronic waste.

Overview: Connect, mount, and secure the new motherboard.

Step 1: Mount and secure the motherboard

Remove the replacement motherboard from its packaging and place it on the back of the display assembly, aligning the five screw holes in the motherboard with the corresponding screw holes in the display. Thread one motherboard mounting screw into each of the five screw holes, then use a Phillips driver to tighten until snug.

Step 2: Connect the ribbon cables to the motherboard

Carefully slide the two ribbon cables into their respective connectors on the motherboard. Push the black latches towards the white connector body. When the latch is flush with the connector body, the ribbon cable is secure.

Step 3: Connect the remaining motherboard cables

Hold the motherboard and display assembly in front of the machine, near its mounting point. Reconnect all cables to the motherboard, using the image here as a reference. Each cable only fits into its connector in the correct orientation. The locking tab clicks into place when the cable is fully connected.

Step 4: Mount the motherboard and display assembly

Inclina leggermente verso l'alto la scheda madre e il gruppo display. Inseriscila sotto il bordo anteriore della scocca superiore, quindi inclina la parte inferiore dell'assemblaggio in posizione. Assicurati che sia allineato con il corpo dell'apparecchio e che i quattro fori delle viti nella parte inferiore della scheda madre e del gruppo display siano allineati con i fori corrispondenti della Form Cure L V2.

Overview: After installing the new motherboard, perform final checks.

Step 1: Power on the machine

Connect the power cable to the machine and its power supply. Turn on the switch at the back of the machine. Start a post-cure cycle and check that the machine operates normally.
