¶ 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, open a new ticket in our Support Page and we will do our best to respond promptly and provide the assistance you need.

Important reminder! The blade has sharp edges and corners. There is a risk of cuts during the operation. Please be careful!
¶ Optional - Clean the extruder gears
Before you proceed with installing the new cutter, it is recommended that you clean the extruder gears and the yellow gear. After long-term use, some filament residue may accumulate on the extruder gears, and cleaning will ensure smooth operation in the future. You can use a blower or light attachment to blow out the debris inside the extruder and around the gears.
