Solved my heat creep issues

My old hotend struggled with heat creep when printing at higher speeds. This ceramic block dissipates heat much better, allowing me to push my Neptune 4 Max to its limits without failures.

Good value for the price

For the cost, you get a significant upgrade in thermal performance. I deducted one star only because the instructions could be more detailed for beginners, but online guides helped.

Solid construction

The brass nozzle heats up quickly and maintains temperature precisely. The included silicone sock fits perfectly. Highly recommend for anyone looking to expand their material options.

Perfect upgrade for high-temp materials

I switched to this ceramic hotend kit to print more ABS and Nylon, and the difference is night and day. The temperature stability is excellent, and I haven't experienced any clogging since installation.

Great quality, tricky install

The components feel very premium compared to the stock parts. Installation took a bit longer than expected because the wiring needed careful routing, but once running, prints are flawless.

Essential for serious printing

If you own a Neptune 4 Plus, this kit is a must-have. The ceramic insulation keeps the heat exactly where it needs to be, resulting in smoother layers and better adhesion.

5 FAQ

Q: What is the maximum safe continuous operating temperature?

A: The kit is rated for continuous operation up to 300°C. Brief spikes slightly above this are tolerated, but we recommend staying within the 300°C limit for component longevity.

Q: Do I need to update my firmware after installing this?

A: Generally, no firmware update is required as the thermal properties are similar to the stock setup. However, you may want to recalibrate your PID settings for optimal temperature control.

Q: Does this come with a new thermistor or do I reuse the old one?

A: The kit includes a brand new high-temperature thermistor pre-installed in the heater block, so you do not need to reuse your old sensor.

Q: Is this kit compatible with the original Neptune 4 (non-Plus/Max)?

A: No, this specific kit is designed exclusively for the geometry of the Neptune 4 Plus and Neptune 4 Max models. Please check our store for the standard Neptune 4 version.

Q: Can I use this hotend with abrasive filaments like Carbon Fiber?

A: While the ceramic block handles high temperatures well, the included brass nozzle is not hardened. For abrasive filaments, we recommend purchasing a separate hardened steel or ruby-tipped nozzle compatible with M6 threads.
