Creality Upgrade Aluminum Bowden Extruder and 24V 40W MK8 Hot End Kit with Capricorn Premium Tubing for Ender 3/ Ender 3 Pro 3D Printer

The quality of components is good and the kit fitted easily. However I was getting snapped filament, or more correctly the extruder drive cog was wearing through the filament whentthe filament got jammed in the tube. The tell tale sign is the extruder clicking. If you search for this problem, there are many diagnosis, issues with the extraction values in your slicer, heat creep, not enough pressure on the extruder spring, poor filament, wrong temperature, blocked nozzle etc. etc. I tried all those then noticed that the filament was being flattened even with the spring tension being wound all the way back. When I measured it with calipers, the filament was being flattened wider than capricorns recommended max size, i.e. 1.8mm, it was about 1.83mm and occasionally 1.86mm. So I checked all the components against the plastic extruder it replaced which is the same design. I noticed the spring was longer in the new extruder. I swapped out the spring with the old shorter spring and it now works fine. Conclusion, wrong or faulty spring in my kit, this could be a one-off or a batch, so if you get incomplete prints with the filament breaking, check the diameter of the filament you pull out of the tube when replacing the filament.

This item was delivered quickly, well made and easy to install. Highly recommend the upgrade to an aluminium extruded from the stock plastic.

Brought this and a new roll of filament from these yesterday. I can’t see any lines or voids in the material. I set my printer up last night to print the creality dog and just can’t believe the result.Better yet the filament game same day in less than 6 hours.

Speedy delivery and all pieces supplied as shown, havent fitted yet as bought for having spares.

I bought this as a replacement for the Sunlu S8's poorly designed extruder setup. The arm on the feeder cracked. This thing has been serving me for a while with no problems at all! Highly recommend!

Simple to install and great value.Everything included to replace the hot end and upgrade the extruder. The Capricorn Bowden tube is excellent with a good length, slightly longer than the stock tube I received.

Bought this to replace my current hotend on one of my printers as it comes with the capricorn tube and it is fantastic quality and all genuine parts, will definitely be ordering again for my other printers!

Improved flow and reliability a must compared to the stock one
