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.

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.

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?
