¶ 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.

Place the torsion spring over the cylinder, ensuring one end of the spring is inserted into the small hole. Then, insert the right cutter lever and blade together into the extruder. Hold the cutter lever to prevent it from loosening, and tighten the screw using the H2.0 Allen key.
Insert the cutter along with the cutter lever into the slot, slowly press it in from the bottom of the cutter lever, and then install the screws to ensure that the cutter lever won't spring open.
¶ Replace the Left Cutter Lever and Blade
Before replacing the left cutter, ensure the hotend is switched to the left hotend.
Use an H2.0 Allen key to remove the fixing screw. Pull the left cutter handle out of the extruder, then remove the cutter blade from the cutter lever.
Insert the cutter blade into the cutter lever. Place the torsion spring over the cylinder, ensuring one end of the spring is inserted into the small hole. Then, insert the left cutter lever and blade together into the extruder. Hold the cutter lever to prevent it from loosening, and tighten the screw using the H2.0 Allen key.
