Replace Ender-3 V4 Cutter

Instructions

The cutter is installed on the right side of the extruder. When the toolhead moves to the rightmost position, the cutter rod compresses the internal cutter through leverage action to cut the filament; after cutting, the cutter returns to its original position by the magnetic force of the built-in magnet.

Multi-color printing and other tasks with frequent filament unloading operations will execute the filament cutting action. After long-term use, the cutter will experience some wear, so regular inspection or replacement is required.

The replacement steps can be referenced as follows:
