BIQU H2 V2S Revo Dual Gear Feeder Extruder Direct Drive Metal Upgrade Kit with 4 Mounting Holes Rapid Change Nozzle for BX Ender 3 Series, Voron2.4, Voron V0, Vzbot 3D Printer

Quick Disassembly & Easy Replacement: After the nozzle is cooled, just unscrew the old nozzle by hand and screw the new nozzle in its place, so that the user can resume printing work in a short time; Moreover, different from the market For other extruders, Revo nozzles are a factory sealed nozzle and heatbreak in one, so they're easy to fit and can't leak material when in use; adding a switch wrench is more convenient and laboratory saving, and can be operated operated can with one hand. Lightweight and wide compatibility: BQIU H2 V2S Revo combines the advantages of H2 and E3D Rapidchange Revo, 198g lightweight design, smaller inertia, more accurate positioning, higher printing accuracy, than the ordinary 300g extruder on the market. 34% lighter at launch. Widely compatible with BIQU B1, BIQU BX, Ender-3, Voron2.4, Voron V0, Vzbot 3d printer, etc. Adjustable filament loading tension and dual gear feeding: simply rotate the tension screw to accommodate different filaments, improve the printing success rate, improve the printing performance of flexible filaments, compatible with most filaments on the market, such as: ABS/PLA/PVA/HIPS/PET/PET etc. 7:1 gear ratio; 7.5 kg maximum extrusion force, H2 V2S Revo features a dual-gear system to provide an exceptional exceptional pushing force, ensuring smooth feeding and giving snappy retractions. Revo HeaterCore & High Temperature Print: Heat up much faster than a typical heaterblock. It's designed to be much safer, too – a positive temperature coefficient (PTC) means power reduces as it gets hotter, reducing hazards in the event of a thermal runaway. Supportable 300°C high temperature printing filament Efficient Heat Dissipation & More Mounting Holes: The lightweight and wear-resistant aluminum alloy housing, high thermal conductivity heat sinks, and fan realize a better heat dissipation.4 screw mounting holes are available for installing an auto leveling sensor/cooling fan, which can achieve more Function. Its young and personalized design is also enough to catch the attention of most 3D enthusiasts
