HEXA RF - Mainboard Replacement Guide

Tools

Step 1

Turn off the machine and remove the power cord.

Step 2

Use a T8 Torx screwdriver to open the side cover, which is inside the work area.

Step 3

It's strongly recommended to shoot a video recording of every cable's position in case you forget where you plugged them back in. (The video below is only a demonstration. The arrangement of the cables might be different.)

Step 4

Since the motor cables use the same socket type on the mainboard, mark the X-, Y-, and Z-axis motor cables to avoid plugging them into the wrong socket when reinstalling.

Make sure you take photos to ensure each cable's mark.

X-axis	Y-axis	Z-axis

Step 4

Remove the camera cable (CAM1) at the top, and mark it to indicate it will be plugged into the top USB port (CAM1).

Make sure you take a photo to ensure the cable's mark.

Step 5

Unplug all the cables from the mainboard.

Step 6

On the right side of the machine, remove the T8 screws to detach the mainboard from the system.

Here is a demonstration of how to take out the board through the hole.

Step 7

Remove the standoff screws from the mainboard by holding the standoff while unscrewing the T8 screw.

For other sockets, please refer to this diagram that shows which sockets should be empty.
