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 retighten the hot end isolator every three months to ensure the parts are connected securely.
Caution: This procedure requires heating up the nozzle. Be careful and do not touch the hot nozzle with your bare hands. Protective (thermal) gloves are advised. Ensure the Ultimaker 2+ Connect is disconnected from the Digital Factory or made unavailable for new print jobs.
