Ador - Y-axis Motor Replacement

Tools

Step 1

Turn off the machine and unplug the power cord.

Flip the machine to see the bottom of the machine.

Step 2

Mark the rubber foot and screw that are close to the USB port.
The purpose of marking is that this foot's screw will be shorter than others, and it has to be in the same position.

Step 3

Unscrew these bottom screws.
(T8 screw x 6pcs ＆ 3mm HEX screw x 4pcs)

Step 4

Flip the machine over and remove the side screws. (T8 screw x 2pcs)

Step 5 

Mark the screw holes on both sides with the pen.
This marking helps ensure the correct orientation during reassembly. The marked sides should face the work area.

Step 6

Remove the screws. T8 screw x 8pcs (The plate and door cover are connected.)

Step 7

Move the plate and door cover forward a bit.

Step 8

Remove the Y-axis motor cable. (It is easier to remove the camera cable after removing this cable.)

Step 9

Remove the camera cable.
Please note that there is a clip locking the cable. Open the clip to remove the camera cable.

Clip Unlocked:：

Pull out the cable：

Step 10

Remove the plate and door cover.

Step 11

Unplug the 7-pin cable.

Step 12

Lift the rear side of the upper chassis and rest it on the lower chassis.

Step 13

Find the Y-axis and detach the coupler and the shaft. (2mm hex screw *4pcs)

Step 14

Loosen the rail support bracket and move it aside. (3mm hex screw x 3pcs)
(This support will block a screw of the Y-axis motor.)

Step 15

Remove the Y-axis motor from the system. (2.5mm hex screws x 4pcs.)

Step 16

Remove the coupler from the Y-axis motor.
(Use a plier if the coupler is stuck on the shaft of the Y-axis motor.)

Step 17

Attach the coupler to the shaft of the new Y-axis motor. (2.0mm hex screws x 2pcs.)

Step 18

Install the new Y-axis motor. (2.5mm hex screws x 4pcs.)

Step 19

Attach the coupler to the long shaft. (2.0mm hex screws x 2pcs.)

Step 20

Screw the rail support. (3mm hex screw x 3pcs)

Step 21

Mount the belt onto the pulley.
(You can use the back of a screwdriver or your finger to guide the belt onto the pulley while slowly moving the laser head. The belt should gradually loop onto the motor's pulley.)

Step 22

Place the upper chassis back in the original setup. Make sure both cables the 7-pin cable and the new Y-axis motor cable are routed upward.

Gently move the laser head around and check if it is moving smoothly, especially for the Y-axis.
If not, please raise the rear side (Step 12) again and check the y-axis belt or the coupler from Step 18 to Step 21.

Step 23

Reinstall the side screws (T8 screw x 2pcs). Make sure the marked side is inside the work area.

Step 24

Flip the machine. Screw all the screws at the bottom.
Please note that the marked rubber foot and shorter screw must be reinstalled near the USB ports.

Suggestion:
It is better not to fully tighten the screws at first, as some screws might be misaligned and unable to be tightened or inserted into the screw holes properly. Therefore, it is recommended to tighten all the screws after all the screws are installed.

Step 25

Flip the machine and plug the 7-pin cable back into the mainboard.
