¶ PTFE Tube
The PTFE Tube on the H2D Printer is used to connect the buffer to the toolhead (both left and right feeder inlets). It helps guide and deliver the filament from the buffer to the toolhead for extrusion during the printing process.
Please note that the PTFE tubes are consumables and are at risk of wear, as they may rub against the filament over time. We recommend that you check the PTFE tubes for wear during your maintenance of the printer.

¶ 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.
¶ Disconnect PTFE Tubes
¶ Step 1: Turn off the printer power and remove the external PTFE tube
Press the black outer ring of the pneumatic connector, then unlock and pull out the PTFE tube.
¶ Step 2: Disconnect the PTFE tubes inside the chamber
Press the black outer ring to unlock the two connectors above the extruder.
Press the black outer ring to unlock the two connectors at the upper and lower ends of the buffer. The connector of the buffer can be pushed to the right for easy unlocking.
Pull out the two PTFE tubes on the left and right.
¶ Connect PTFE Tubes
Put the two PTFE tubes through the holes on the side of the cable chain buckle.
Insert the PTFE tubes into the two pneumatic connectors on one side of the buffer.
Then insert the other end of the PTFE tube into the two pneumatic connectors above the extruder.
Please note that the PTFE tube above the cable chain needs to be connected to the right extruder, and the PTFE tube below the cable chain needs to be connected to the left extruder.
