¶ 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 Dual Extruder Filament Guide
¶ Step 1. Remove the hotend
Please refer to this wiki to remove the hotend: Replace H2D Hotend.
¶ Step 2. Remove the extruder filament guide and left cutter
After unscrewing the four screws (M2.5x7 * 3；BT2x6 * 1) on the extruder filament guide, use your fingers to press upward against the black hotend connector while simultaneously pressing down on the left cutter lever to release it slightly from the opening slot near the cutter screw.
Then, exert force outward from the lower right corner of the extruder filament guide to pry it out.
The left cutter is located within the extruder filament guide and will be removed together when removing the extruder filament guide. Please take care to store it properly to prevent loss.
¶ Step 3. Remove the extruder right hotend connector (optional)
The extruder filament guide comes in versions with three screws and four screws. If the original extruder filament guide differs from the new one, remove the extruder right hotend connector located beneath the extruder filament guide after its removal.

After removing the extruder filament guide, use an H2.0 Allen wrench to remove the two screws securing the right hotend connector, then detach the right hotend connector.
¶ Install the Dual Extruder Filament Guide
¶ Step 1. Install the extruder right hotend connector (optional)
The extruder filament guide comes in versions with three screws and four screws. If the original extruder filament guide differs from the new one, before installing the extruder filament guide, first install the extruder right hotend connector located beneath the extruder filament guide.

Attach the right hotend connector, and use an H2.0 Allen wrench to tighten the two screws, securing the right hotend connector.
¶ Step 2. Install the extruder filament guide and the left cutter
The left cutter needs to be installed together with the extruder filament guide. Ensure that the notch of the left cutter is facing upwards, then place it into the cutting blade slot of the extruder filament guide.
When installing the extruder filament guide, make sure to continuously press upwards against the black hotend connector and simultaneously press the left cutter lever, adjusting it to an appropriate angle for easy insertion.
Then, install the extruder filament guide. Finally, press on both sides of the cutter lever, applying force to completely flatten the front cover.
Then, tighten the four screws (M2.5x7 * 3；BT2x6 * 1) on the extruder filament guide.
¶ Step 3. Install the hotend
Please refer to this wiki to install the hotend: Replace H2D Hotend.
¶ Verify the Functionality
First, check if the Dual Extruder Filament Guide is loose. Then, connect the power and turn on the printer. Check whether the left and right hotends can complete normal printing.
