Pull out the cable:
Step 6
Remove the plate and door cover.
Step 7
Mark the location of 38-pin flat cable with pen or tape
Step 8
Remove the cables on the right of the mainboard.
You may take a photo, in case you forgot the position of the cables.
Step 9
Remove the screws on the mainboard.
3mm HEX screw x 4pcs
Step 10
Remove the 38-pin flat cable from the plate.
Please note that there is a tape on the back of the cable.
Pull out the mainboard by 45 degrees.
This cable has to press the lock to be removed.
Remove all the cables.
Step 11
When facing the panel of the machine, on the left side, unplug the X-axis motor cable, remove the two 2mm hex screws, and remove the X-axis board cover.
(A long, thin hex driver is recommended, which gives more hand space.)
Step 12
Open/unlock the clip of the cable and unplug the cable from the X-axis board.
Step 13
Remove the X-axis board by unscrewing the bottom screw, as shown in the video.
Suggest inserting the screwdriver into the screw head first, then using both hands together.
After loosening the board, carefully remove the Y-axis 38-pin ribbon cable.

After uninstalling the parts:
Note
If the screw is too tight to loosen, you can try using an L-shaped hex wrench to loosen it first, and then use a hex screwdriver to remove the screw.
Step 14
Completely remove the 38-pin ribbon cable.
Some sections of the cable may have adhesive backing, especially near the motherboard.
Step 15
Guide the new 38-pin ribbon cable through the pre-drilled hole on the X-axis control board (the side without adhesive backing) and insert it into the board.
Pay attention to the orientation, ensuring the blue side of the ribbon is facing toward the terminals, and make sure that the ribbon cable is securely inserted into the X-axis control board.

Step 16
Install the X-axis control board by screwing the 'short' screws underneath. (Screw Location)
On the side with adhesive backing, make sure it faces toward the sheet metal, as shown in the video.
Step 17
Install the 30-pin cable on the Z-axis board. The cable should be in the middle of the slot. If installed correctly, the clip should be able to be locked easily.
Please see the following description to confirm the position where the cable should be inserted and ensure that the cable is installed correctly.
-
The two edges of the cable slot will be slightly higher, as shown in the picture.
-
The cable needs to be inserted in the middle. When inserted correctly, it should be at the same height as the edges, as shown in the picture.
(The clip is not locked in the picture.)
-
Only by inserting it correctly can the clip be locked easily, and the cable should be parallel to the slot, as shown in the picture. (The clip is locked in the picture.)

Step 19
Inster the 38-pin Cable into the mainboard.
Please make sure the direction of the cable is correct, as in the photo.
Step 20
Plug the cables into the mainboard.
Step 21
Reposition the mainboard into the position.
First, insert the 38-pin ribbon cable into the gap, ensuring the bottom edge of the mainboard touches the bottom. Then, shift it left to align the mainboard screw holes.
Step 22
Fix the mainboard by screwing the screws.
Step 23
Plug the cables except the camera and the motor cable.
Step 24
Peel off a small section of the adhesive backing from the ribbon cable near the X-axis control board. Then, push the ribbon cable at the corner of the mainboard all the way down, aligning it with the marked line, and initially attach a portion. Once the position is confirmed, remove the remaining backing from the adhesive and firmly adhere it in place."
Step 25
Move the module in the Y-direction and see if the 38-pin cable's movement is smooth.
Step 26
Turn on the machine and try auto-focusing to see if it works.
- It works normally > Please continue to Step 27
- The module doesn't move at all > Replug the 38-pin cable > Go back to Step 8
- The module moves, but focus fails> Replug the 30-pin cable > Go back to Step 11 - 12 and skip to Step 17 - 18
Step 27
Put the plate and the door cover on the top. Leave a space to allow your hands to reach.
Step 28
Insert the camera cable into the mainboard.
Please note that the metal surface of the camera cable must face the mainboard.
