Remove the X-carriage PCB

To access the x-carriage PCB we need to remove the right bridge end plate and slide out the cable tray.

The right side of the bridge does not have ribbon cables.

1

Remove the bridge 90° mounting bracket

Remove the two T25 torx screws securing the 90º mounting bracket to the bridge.

2

Remove the right bridge end plate

Using a screwdriver along with a T20 and a T10 torx bit remove all of the screws securing the bridge end plate.

  • T20 - Yellow highlight

  • T10 - Green highlight

3

Remove the bridge cable tray

Remove the two T10 screws securing the bridge cable tray to the left bridge end plate.

Now you can slide the bridge cable tray off of the bridge.

4

Remove the X-carriage bottom plate

Using a 3mm hex key remove the 4 screws securing the x-carriage bottom plate to the bridge.

5

Remove the X-carriage PCB

Use a screwdriver and T6 torx bit to remove the two screws securing the port connectors to the x-carriage PCB.

Disconnect the port flex cables from the x-carriage PCB by using your fingers to lift up on the metal tabs.

Lift the x-carriage PCB out of the bridge and disconnect the left and right motor wire harnesses on the backside of the board by pinching the release tab on either connector.

With the x-carriage board loose from the bridge, remove the plastic clip securing the ribbon cables and disconnect both ribbon cables.

In case you've forgotten, here is a video of how to properly disconnect a ribbon cable:

How to disconnect a ribbon cable

Reassemble the bridge

1

Connect the new X-carriage PCB

Connect the new x-carriage PCB to the ribbon cables. Ensure that the cables are fully inserted and the blue end is sitting parallel to the connector.

Install the black plastic cable clip so that it holds the ribbon cables to the x-carriage PCB.

Connect the left and right motor wire harnesses to the backside of the x-carriage board.

Ensure that the two port flex cables are accessible and sitting outside of the tool carriage.

Push the x-carriage PCB into the tool carriage so that it sits flush and the port flex cables are accessible.

Connect the port flex cables by pushing the end of the metal cable downward into the connector. It will click into place.

Secure the two port flex cables to the x-carriage PCB using the T6 torx screwdriver.

2

Attach the X-carriage bottom plate

Using a 3mm hex key attach the x-carriage bottom plate to the bridge with the 4 black screws.

3

Attach the bridge cable tray

Slide the bridge cable tray into place.

Secure the bridge cable tray to the left side of the bridge with two M3 x 12 self tapping screws.

4

Attach the right bridge end plate

Attach the bridge end plate to the bridge using a screwdriver in order:

  1. T20 - Red highlight

  2. T10 - Yellow highlight

  3. T10 - Green highlight (finger tight)

5

Attach the bridge 90° mounting bracket

Secure the 90º mounting bracket to the bridge using a screwdriver with a T25 torx bit.
