Safety Warning

IMPORTANT!

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.

Steps to remove the old screen

For easy access to the bottom section of the A1, you need to place the printer on the front.

Start by flipping the screen on its side, then gently place the printer on its front, as shown in the image below.

Use a box of filament to keep the top side raised to avoid putting pressure on the extruder and the screen.

2. Disconnect the wires and remove the wire bracket

1.Disconnect the cables of the camera, X-axis motor, and Z-axis motor;

2.Loosen 1 screw;

3.Push the cable bracket upwards, disconnect the USB data cable, and remove the cable bracket.
