Step 1
Remove the laser or printing module if you have installed any.
Step 2
Use an Allen key to remove the belt spring on the X-axis belt.
Step 3
When facing the panel of the machine, on the left side, unplug the X-axis motor cable.
Step 4
Turn off the machine, remove the power cord, and flip the machine.
Step 5
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 6
Unscrew these bottom screws.
(T8 screw x 6pcs & 3mm HEX screw x 4pcs)
Step 7
Flip the machine and unscrew the side screws (T8 screw x 2pcs)
Step 8
Mark the screw holes on both sides with the pen.
The purpose is to remind yourself that the marked sides will be facing the work area when assembling.
Step 9
Move the module seat to a position that has a distance of around 10cm from the frame.
(The purpose here is to not block the X-axis gantry. If it is at the very back, it will be locked after lifting up, and the X-axis motor can't be reached. If it is in the middle, the Y-axis 38-pin cable might get damaged)
Step 10
Lift the upper frame with both hands and place it on the studs.
(Be careful not to get the wires stuck by the frames.)
Example of frame sitting on the studs:

Step 11
Loosen the X-axis motor by unscrewing these four screws with a 2.5mm Allen key.
Step 12
Snip off the cable tie so the motor can be removed.
Step 13
Push the X-axis to the back gently. This will make more space for the left side.
Step 14
Install the new X-axis motor by first mounting the belt on the gear.
Make sure the belt is in the ready position before mounting on the motor.
The wires of the motor should be facing out, as in the photo below.
Step 15
Screw back the four screws to fix the motor with a 2.5 mm Allen key.
Step 16
Plug the motor cable into the X-axis control board as in the photos below.
Step 17
Restore the position of the upper frame.
Please note that the marked screw holes have to be facing the work area.
Restoring the frame:
Step 18
Screw the side screws.
Step 19
Flip the machine. Screw all the screws at the bottom.
Please note that the marked foot and screw will have to be in a position close to the USB ports.
Suggestion:
It is better not to fully tighten the screws at first as some screws might be misaligned and unable to have the screws put in. Therefore, it is recommended to tighten all the screws after all the screws are installed.
Step 20
Flip the machine. Move the module seat around to see if it can be moved freely.

Step 22
Re-install the spring on the X-axis belt.
