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.
Control the heatbed through the screen and lower it to the bottom of the printer.
After lowering the heatbed, turn off the printer and disconnect the power.
Before removing the left side panel, you need to remove the rear panel first. You can refer to this Wiki to remove the H2D rear panel:
Use an H2.0 Allen key to remove the 4 screws (M3x3, nut diameter 10mm) that secure the front door, 2 screws on the top and 2 screws on the bottom, then hold the front glass door with one hand and remove the front door.
Be sure to hold the front glass door with your hand to prevent it from falling.
You need to remove the auxiliary part cooling fan first because there is a side panel fixing screw behind the auxiliary part cooling fan.
The auxiliary part cooling fan is fixed with soft screws (two in the upper row) and screws (two in the lower row). You can use an H2.0 Allen key to remove the two fixing screws (BT3x16) in the lower row, pull the fan hard to remove the soft screws, and then place the fan on the heatbed without disconnecting the connectors from the MC board.
You can also refer to this wiki for detailed steps on removing the auxiliary part cooling fan:
Replace H2D Auxiliary Part Cooling Fan
Note: The corresponding holes are reserved on the AP board. The two fixing screws of the upper frame can be removed without removing the AP board. The following figure shows the AP board removed for easy shooting.
If your soft screws are not damaged or are long enough to pass through the auxiliary part cooling fan, you can ignore this step and do not need to replace the soft screws.
You can remove the two soft screws from the printer beam by pulling them on the outside.
If your soft screws are not damaged or are long enough to pass through the auxiliary part cooling fan, you can ignore this step and do not need to replace the soft screws.
Insert the soft screw through the small hole in the beam and pull the soft screw until it snaps into the beam.
It is recommended to push the buckle on the back of the printer first, as these clips do not have fixed tabs, making them easier to push in.
The buckles are redundantly designed. If they break during the disassembly and assembly process, it will not affect normal use. It is fine as long as there is no floating.
If the opening is difficult to tear open, you can use an Allen key to assist in prying it open.
Method One:
Note:
You can hear a "click" sound when the soft screw is pulled into place;
The soft screw is made longer at the factory for easy installation. After installation, you can use scissors to cut off some of it for a better appearance.
Note: The fixing screws of the H2D auxiliary part cooling fan are all located in the small holes on the top.
Method Two:
Align the 4 screw holes on the front door with the screw holes on the hinge, hold the front glass door steady with your hands, and use an H2.0 Allen key to tighten the 4 screws (M3x3, nut diameter 10mm).
