Fast shipping and great product
Arrived quickly and well-packaged. The hardened nozzle is a must-have if you plan to print any abrasive filaments. Very satisfied with this purchase.

Solid components
The build quality of the metal parts is excellent. Installation took about an hour. My printer is running smoother than ever, though I wish it came with a spare hotend fan.

Great value kit
Everything fit perfectly. The extruder kit was easy to install following the manual. Only giving 4 stars because the instructions could be slightly more detailed for beginners.

Solved my slipping issue
My old extruder was struggling with TPU filament. This new dual-drive extruder kit handles flexible materials like a charm. Highly recommended for TPU users.

Essential maintenance parts
I bought this as a spare parts kit. The timing belts are high quality and the pulleys align perfectly. It's good to have these on hand for long-term maintenance.

Perfect upgrade for high-speed printing
Installed the hardened steel nozzle and new belts on my Neptune 4 Max. The print quality at high speeds improved significantly, and the vibration is noticeably reduced.
Q: What is the length of the timing belt included?
A: The timing belts are pre-cut to the exact specifications required for the Neptune 4 Plus and 4 Max axis lengths. No cutting or adjustment is needed.
Q: Can the hardened steel nozzle print carbon fiber filament?
A: Yes, the included hardened steel nozzle is resistant to abrasion and is suitable for printing composite filaments like carbon fiber, glass fiber, and wood-fill.
Q: Does this kit improve printing speed automatically?
A: While the hardware supports higher speeds, you will need to adjust your slicer settings and firmware acceleration limits to fully utilize the high-speed capabilities.
Q: Do I need special tools to install the extruder kit?
A: The kit includes the necessary Allen keys for installation. However, having a small set of screwdrivers and pliers handy may make the process easier.
Q: Is this kit compatible with the original ELEGOO Neptune 3?
A: No, this accessory kit is specifically designed for the Neptune 4 Plus and Neptune 4 Max models due to differences in the extruder and motion system architecture.
