H2 extruder V2.0 direct drive extruder for ender 3 dual gear extruder not stuck direct extruder 1.75mm filament new upgraded 3D printer extruder for Ender 3 Pro Ender 5 Ender 6 CR10

H2 extruder V2.0 direct drive extruder for ender 3 dual gear extruder not stuck direct extruder 1.75mm filament.

Features of H2 extruder V2.0

• Upgraded Version of Stainless Steel Gear: high temperature resistance, durability, high precision, and higher surface finish. The output gear modulus design was changed from 0.5 to 0.25, reducing the gear outer diameter, effectively solving the weak points of V1.0 gear jamming and unsmooth extrusion.
• All-in-one Design & High Precision: The short-range extruder integrates the hot end of the nozzle, extruder, stepping motor, cooling fan, etc., double-gear extrusion, fast extrusion of consumables, short-range extrusion, short thread, and accuracy High, the control of the feeding amount is more accurate than remote extrusion, the withdrawal is more accurate, and the printing quality is better.
• Extremely Smooth & Reducing Clogging:  The smoothness of the throat and the inner wall of the nozzle reaches Ra0.4, which can effectively prevent clogging. H2 V2.0 adopts high-quality titanium-copper alloy hose, which has better heat dissipation and high temperature resistance, and the printing temperature can be as high as 400°C. It is the best quality hose material on the market. The hose is easy to disassemble, making it easier to use. convenient.
• Wide Compatibility: BIQU H2 extruder V2.0 has wide compatibility and can be installed in common 3D printers on the market, BIQU B1, Ender 3(V2), Ender 6, CR-10S Pro, CR-10 V2/V3, Mega X, X1 Genius, etc. At the same time, you can also DIY according to your personal needs and update the corresponding firmware to meet your DIY needs.
