When to change

If there is a problem with the supply cutting or the blade becomes dull, please refer to the following guide. As the time of use increases, the blade will decrease sharpness.

To maintain cutting performance, it is recommended to change the cutter every 10-15 rolls of consumables (or less).

After about 5,000-7,000 consumables are cut, the blade may become dull, but it usually does not deform. Please refer to the figure below.

If you encounter AMS filament shrinkage problems, it is recommended to replace the blade to ensure optimal results. The sharp blades cleanly cut the filament and avoid problems in operation.

Common issues that require replacing consumable knives include:

Consumables are not cut cleanly

Wear of cutting blade

Operation Guide - Installation

1. Install the cutting blade

Installing a new cutter is very simple. Just align the cutter with the installation slot and insert it into place. Then, gently push in the direction shown in the figure below to secure the cutting blade in place.

2. Fix the position of the cutter handle

After installing the blade in the fixed position on the cutter handle, ensure that the blade is aligned with the hole of the extruder.

Before re fixing the screws, please grip the cutter handle tightly and maintain its position. When tightening the screws, please be careful not to apply too much force to prevent the occurrence of anti-skid threads.

3. Install the front cover of the tool head

Align the top buckle of the front cover of the tool head and gently press down on its lower part. After ensuring proper installation, you will hear a crisp sound.

4. Verification

To ensure proper functioning, please press the blade handle several times and ensure smooth movement, allowing the handle to return to its initial position. This will ensure smooth operation during use.
