Helpful Hints for using the Chube Hotend
Meltzone Adapters:
- Make sure your meltzone adapter (MZA) is tightened down fully. These can be hot-tightened!
- Your meltzone adapter is torx, just like the screws used for Chube
Heater and Thermistor Install:
- Apply BN paste to your heater and thermistor, before inserting into the heatblock.
- Only tighten grub screws until they prevent your heater and thermistor from coming out. If you tighten down too tight, it can lower the lifespan of your components.
- For Chube Conduction, it is perfectly normal for your supervolcano heater to protrude from the block
Shields:
- Tighten Fully – you shouldn’t see space between the heatblock and the shield.
Chalice Heatbreak:
- Tighten to 3NM (Newton Meter). We tighten each heatbreak before shipping, so if you remove your heatbreak, be sure to retighten to prevent leaks. If you are retightening your Chalice, you should first loosen your Meltzone Adapter. After you've tightened Chalice, retighten your meltzone adapter.
- Apply thermal grease to the outside cup portion of the Chalice Heatbreak. We do grease them during our assembly process.
- Your PTFE needs to be deeply seated within the Chalice.

Question: Is my Chalice Heatbreak clogged?
Answer: Probably not, generally the Chalice “clogs” are due to the PTFE not being seated down far enough. To know for sure, you can remove your heatsink quite easily, it is only 3 torx screws. Check below for a video demonstrating a “clog” that is really due to PTFE seating issue.
Question: How do I remove the Blockage?
Answer: It should slip out easily, due to the lubricous coating on the heatbreak. You should be able to easily pop it out by carefully using a pick, or similar small tool. Tweezers, unless you make sure to grab carefully, may result in breaking off the easier to reach portion of your filament.
If you do end up breaking the easy-to-reach part of your filament, Chalice can be torched a bit, in order to melt/loosen the remaining plastic. The entire hotend is 500c rated. Please wear proper equipment if you use a torch: gloves, glasses, tie your hair back (if applicable).
Mounting:
- Use all 6 bolts for mounting Chube to your printer
