Retighten the hot end isolator

The hot end isolator connects the separate parts of the hot end. It is important that the hot end isolator is properly screwed onto the heater block to prevent any material from gathering between these parts. If material does gather between these parts, it can lead to print quality issues or blockages.

It is recommended to re-tighten the hot end isolator every three months to ensure the parts are connected securely.
