Safety Warning
IMPORTANT!
It's crucial to power off the printer before conducting any maintenance work, including work on the printer's electronics and tool head wires. Performing tasks with the printer on can result in a short circuit, leading to electronic damage and safety hazards.
During maintenance or troubleshooting, you may need to disassemble parts, including the hotend. This exposes wires and electrical components that could short circuit if they contact each other, other metal, or electronic components while the printer is still on. This can result in damage to the printer's electronics and additional issues.
Therefore, it's crucial to turn off the printer and disconnect it from the power source before conducting any maintenance. This prevents short circuits or damage to the printer's electronics, ensuring safe and effective maintenance.

Remove the Front Cover
Step 1: Remove the front cover
- Use an H1.5 Allen key to remove a fixing screw (BT2×12), then hold the buckle on the left side of the front cover with your hand, snap off the top left side of the front cover, and then snap open the top right side:
- Then place your thumbs on the bottom of the front cover and push upwards to unlock the front cover card. Then hold the right side of the front cover to bend it slightly and pull the right side of the front cover out from under the right side panel.
Please pull it out carefully to avoid damaging the screen FPC!
- After pulling the right side of the front cover out of the printer, carefully flip the front cover over to expose the interface between the screen and the screen FPC. Unfasten the buckle of the screen cable upwards, and then remove the screen cable from the buckle.
Step 2: Remove the screen
- Place the front cover on the table, use an H2.0 Allen key to remove the two screen hinge fixing screws (M2.5x4), and then tear off the screen FPC from the front cover (you can use tweezers to help tear it off);
- Hold the front cover, tilt it upwards, pull the screen pins out of the front cover, and remove the screen.
Install the Front Cover
Step 1: Install the screen
- First, thread the screen FPC through the small hole in the front cover. Align the screen pins with the small holes on the front cover and insert them.
- Secure the front cover onto the screen by aligning the screw holes. Tighten the two securing screws (M2.5x4) using the H2.0 Allen key. Finally, adhere the FPC to the front cover.
If the original adhesive is insufficient, use double-sided tape.
Step 2: Install the front cover
- Position the left side of the front cover near the printer’s left side. Insert the screen FPC into the connector and fasten the black clasp.
- Hold the right side of the front cover and gently bend it, then insert it into the printer. Press the front cover down to ensure all snaps are secured.
- Finally, use the H1.5 Allen key to tighten one fixing screw (BT2x12).
Verify the Functionality
Please check whether all the buckles of the front cover are in place and whether the screws are tightened to ensure that the front does not shake.
Then turn on the printer. If the LCD screen lights up and displays a normal display, and the touch screen function responds normally, the replacement is complete.
Since it involves disassembling the screen, we recommend testing whether the screen function is normal after installation.
Otherwise, please check the connection cable again and try again. If it still does not work, please обратитесь в техническую поддержку Bambu Lab для получения дальнейшей помощи.
