It's crucial to power off the printer before performing any maintenance work on the printer and its electronics, including tool head wires, because leaving the printer on while conducting such tasks can cause a short circuit, which can lead to additional electronic damage and safety hazards.
When you perform maintenane or troubleshooting on the printer, you may be required to disassemble some parts, including the hotend. This process can expose wires and electrical components that could potentially short circuit if they come into contact with each other or with other metal or electronic components while the printer is still on. This can damage the electronics of the printer and cause further damage.
Therefore, it's essential to switch off the printer and disconnect it from the power source before doing any maintenance work. This will prevent any short circuits or damage to the printer's electronics. By doing so, you can avoid potential damage to the printer's electronic components and ensure that the maintenance work is performed safely and effectively.

Stand the printer upright and raise the X-axis to the top position.
Push the heatbed forward and take off the Y-axis Top Cover.
Left side down the printer to expose the cable box on the bottom, and disconnect the camera cable(White mark), X motor cable(Green Mark), and Z motor cable (Yellow Mark)in sequence.
Loosen a silver screw and slide the cable box to disconnect the USB cable, then open the Z-motor cable cover and remove the Z-motor cable from the box.
Move the heatbed forward to the end and use an H2.0 hex key to remove 10 screws. Move the heatbed backward to the end and use an H2.0 hex key to remove 2 screws.
Lift one side of the bottom base assembly first, and then remove the entire assembly.
Avoid the touch screen and place the heatbed face down on the table.
Remove the Rear Bottom Cover by unscrewing the 6 screws with an H2.0 hex key.
Remove the Front Bottom Cover by unscrewing the 10 screws with an H2.0 hex key.
Remove the protective rubber sleeves from the cables. First, disconnect the heatbed power cord (Black & White cable)from the AC Board, and then disconnect the signal cable(4 PIN cable).
Using an H2.0 hex key, remove the ground screw and release the ground cable(Yellow-green cable). Next, remove the cables from the cable holes and carefully pull them out from the base housing.
Turn the bottom base over so that the heatbed is facing up, and remove the 4 soft rubber plugs with tweezers.
Using an H2.0 hex key, unscrew the 4 screws and then remove the Heatbed Unit.
Confirm the installation position and place the Heatbed Unit on the bracket. Viewing from the left or right will make it easier for you to align the screw holes, and then tighten the 4 screws to secure it in place. Finally, place back the 4 soft rubber plugs.
Straighten out the heatbed cables and thread them through the cable holes in the base housing. Secure the rubber plug in place. Connect the heatbed signal cable （4PIN cable）and the heatbed power cables (Black & White cable).
Install the protective rubber sleeves on the power cord sockets. Organize the signal cable and secure it with tape. Connect the heatbed ground cable (Yellow-green cable) to the Y-axis Linear Rail and tighten the screw to secure it.
To avoid damaging the touch screen, carefully place the heatbed face down on the table.
Next, install the Front Bottom Cover and tighten the 10 screws to secure it in place.
Then, install the Rear Bottom Cover and tighten the 6 screws to secure it in place.
Keep the Printer Frame upright and carefully install the bottom base assembly onto it, ensuring to avoid the Z-motor cable.
Move the heatbed forward to its furthest position and securely fasten 10 screws. Then, move the heatbed backward to its furthest position and tighten 2 screws.
Place the printer in a backward position and connect the Z-motor cable to the cable management box.
Install the cable management box onto the bottom base, slide it along the slot direction, connect the USB cable, and tighten one silver screw.
Follow the text prompts and color labels to connect the X motor cable(Green mark), Z motor cable(Yellow mark), and camera cable(White mark). Organize the cables properly and ensure they are not being pressed or tangled.
Place the printer upright and move the heatbed forward to its furthest position. Take the Y-axis Top Cover and pass it over through the bottom of the heatbed. Push the cover forward until it reaches the end, ensuring that the cover aligns with the clips. Install the cover in place easily by securing it onto the clips.
Special note: If the heatbed is not moved all the way to the end, the Y-axis Top Cover may get stuck in the wrong position. In such a case, you can manually lift the Y-axis cover slightly to assist in its installation.
1. Please verify that the printing is smooth and free from any shaking. If there is noticeable shaking, please double-check the correct installation of the bottom cable box and ensure that the cables are within the range of the cable buckle.
2. Turn on the power and check if the heatbed can heat up properly.
If any abnormalities occur, please check the connection cables and try again.
When conducting the check, always remember to disconnect the power cable first.
Perform equipment calibration, primarily focusing on Auto Bed Leveling.
