The Form Cure L V1 system on a module (SOM) plugs in to the motherboard and runs firmware on the machine. A malfunctioning SOM may cause the machine to freeze during initialization or fail to turn on.

Use this guide to replace the Form Cure L V1 SOM.

Estimated time: 20–30 minutes

Overview: Prepare the Form Cure L and a dust-free workspace for replacing the SOM.

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

Disconnect the power cable from the machine 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.

Overview: Unscrew and remove the top shell from the Form Cure L to access the SOM.

Step 1: Unscrew the top shell retention screws

The top shell is secured to the frame of the machine with six hex screws. When facing the front of the Form Cure L, two screws are located on the right side and four are located on the left. Use a 2.5 mm hex driver to unscrew and remove the screws.

Step 2: Remove the top shell

Slide the top shell towards the back of the machine to unhook it from the frame. Lift the top shell away from the machine and set it to the side.

Overview: Unplug the Wi-Fi antenna from the SOM.

Step 1: Disconnect the Wi-Fi antenna from the SOM

The Wi-Fi antenna is plugged into the SOM at the top- right corner of the board. The connector is accessible through a cutout in the heatsink. Grip the antenna’s connector by its housing and disconnect it from the SOM. Do not pull on the antenna itself.

Overview: Unplug and remove the SOM.

Step 1: Unscrew the SOM retention screws

The SOM is plugged into the motherboard and secured with two screws on the top side of the module. Using a 1.3 mm hex driver, loosen and remove two SOM retention screws. Set the screws aside.

Step 2: Unlatch the SOM

The SOM is additionally secured via two latches: one on the left side of the board and one on the right.

Using fingernails or a small flat-blade screwdriver, open the two latches securing the SOM into its socket. The SOM may tilt forward once you have opened both latches.

Step 3: Remove the SOM

Lift the SOM up from the edge opposite its connector and carefully pull it free from the socket. Place the SOM on a static-free surface.

Overview: Install and secure the replacement SOM

Step 2: Reconnect the Wi-Fi antenna

The Wi-Fi antenna is plugged into the SOM at the top-right corner of the board. The connector is accessible through a cutout in the heatsink. Align the connector housing on the end of the antenna cable over the socket on the SOM. Using a finger or the tip of a small flat-head screwdriver, push gently to seat the antenna cable.

Overview: Reinstall and secure the top shell

Step 1: Reinstall the top shell

Lower the top shell onto the Form Cure L. Make sure you do not pinch any wires between the shell and the frame of the machine. Slide the top shell towards the front of the machine to hook it into place. Check that the screw holes in the top shell line up with the corresponding screw holes in the frame of the machine.

Step 2: Secure the top shell

Thread one 2.5 mm hex screw into each of the six screw holes in the top shell. Using a 2.5 mm hex driver, tighten the screws until finger tight.

Overview: After replacing the SOM, power on the machine and perform final checks.

Step 1: Power on the machine

Connect the power cable to the Form Cure L and the power supply. The machine initializes. Test the machine to ensure that it operates normally.
