¶ 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. For any concerns or questions about following this guide, we recommend submitting a technical ticket regarding your issue and we will do our best to respond promptly and provide the assistance you need.
¶ Remove the automatic top vent
¶ Step 1: Remove the front cover
Just remove the screen and front cover together. No need to remove the screen from 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 cable!
- After pulling the right side of the front cover out of the printer, carefully flip the front cover from right to left to expose the interface between the screen and the screen cable, buckle the screen cable upwards to open the buckle, and then remove the screen cable from the buckle.
¶ Step 2: Remove the automatic top vent
The automatic top vent is buckled on the upper frame by 4 buckles and connected to the motor through a swing rod.
- You can first pry open the buckle on the far right with an Allen key, then use an Allen key to pry open the buckle on the far left, then remove the 2 middle buckles inwards one by one, and finally remove the buckle on the far right facing outwards.
If the swing rod is damaged during replacement, a spare swing rod can be used.
- After removing the buckle, you can move the automatic top vent to the left to remove the swing rod from the automatic top vent.
¶ Install the automatic top vent
¶ Step 1: Install the automatic top vent onto the upper frame
- Insert the new swing rod into the automatic top vent first, then hold the automatic top vent, align the swing rod with the motor shaft, and use the Allen key to help push the swing rod into the motor shaft;
- First, press down the 2 buckles in the middle of the automatic top vent and buckle them into the buckles. Then press down the 2 buckles on the left and right sides in turn and buckle them into the upper frame.
¶ Step 2: Install the front cover
- First, move the left side of the front cover closer to the left side of the printer, insert the screen cable into the plug, and then fasten the black buckle;
- Then hold the right side of the front cover and bend it slightly, insert the right side of the front cover into the printer, and then press the front cover down to make sure all the buckles are in place.
- Finally, use a H1.5 Allen key to tighten a fixing screw (BT2x12).
