¶ 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 Hotend
Always check the current temperature of the hotend before replacing it to avoid burns due to high temperatures!
The H2D printer has two hotends, left and right, which you can replace as needed.
¶ Remove the left hotend
You can switch the hotend using the screen. Switch to the left hotend, then remove the silicone sock for hotend, unlock the hotend buckle, and remove the hotend from the hotend heating assembly.

¶ Install the Hotend
Both the left and right hotends are secured to the hotend heating assembly via buckles. Install the new left/right hotend onto the corresponding left/right heating assembly, then fasten the buckle and reinstall the silicone sock for hotend.
Since the hotend was already switched to the corresponding side during the removal process, you can proceed directly with the installation.
The example below demonstrates the installation of the right hotend. The left hotend can be installed using the same method.
