Upgraded my CR10 successfully

Switched from the stock setup to this kit on my CR10. The heat distribution is much more even, reducing stringing significantly. Highly recommended for DIY enthusiasts.

Great for learning upgrades

As someone new to 3D printer maintenance, this was a good challenge. Everything fit well, and now I understand my machine better. Just take your time during assembly.

Good value but instructions could be better

The quality of the components feels solid for the price. Installation took a bit longer than expected because the wiring diagram wasn't very clear, but it works great now.

Works fine, shipping was slow

The product itself functions as described and fits my Ender 3s without modification. However, the package took two weeks to arrive, which delayed my project.

Excellent thermal performance

I run this at 24V and it heats up incredibly fast. The brass nozzle is high quality and hasn't shown any wear after printing over 500 grams of PLA.

Perfect replacement for my Ender 3

My old hotend was clogged beyond repair, and this kit fit perfectly. The temperature stability is excellent, and prints came out smooth immediately after installation.

5 FAQ

Q: Is the thermistor pre-installed or do I need to install it myself?

A: The thermistor comes pre-installed and secured within the heater block to save you time during the upgrade process.

Q: Will this work with abrasive filaments like carbon fiber?

A: This kit comes with a standard brass nozzle which is not recommended for abrasive filaments. For carbon fiber, we suggest purchasing a hardened steel nozzle separately and swapping it into this hotend.

Q: What is the thread size of the nozzle included?

A: The nozzle features a standard M6 thread, which is compatible with most Creality printer hotends.

Q: Can I use this with a 24V power supply on an Ender 3 that originally came with 12V?

A: You must ensure your entire printer system is upgraded to 24V before using the 24V version of this hotend. Using a 24V hotend on a 12V system will result in insufficient heating.

Q: Does this kit come with a silicone sock for the heater block?

A: No, this specific kit includes the hotend assembly, nozzle, thermistor, and mounting hardware, but the silicone sock is sold separately.
