Using the Slice Engineering Replacement Heat Sink V1.1 is easy. First, make sure your Mosquito or Mosquito Magnum is turned off and cooled down. Then, carefully place the heat sink on it. If you have a 25 mm cooling fan, you can attach it to the mounting point for better cooling. When using it with Bondtech BMG - M, the built - in anti - rotation features will help it fit properly. As for maintenance, keep it clean from dust and debris. You can use a soft brush to gently clean it. Remember, this heat sink is for the new version of the Mosquito hotend, so check the differences in our blog if you're not sure. Always ensure it's at an appropriate temperature before starting your printing tasks.
