• Double-gear and double-pneumatic joint extrusion structure, high extrusion force, enhancing the feed strength , ensuring smooth feeding, better pressure pushes the filament into the printer, not easy to lose steps.
• All-metal aluminum alloy, High quality dual gear extrusion, Compare to the normal plastic drive, this high aluminum metal dual gear extruder is stable and durable.
• NOTE: Compatible with Ender 3 V2, Ender 3 Series, Ender 5 Pro, Ender 5 Plus, CR10 Series and Other 3D printers. ONLY suit for 3d printers with motor shaft over 20mm, please measure the shaft length before placing the order.
• The product material adopts brand-new imported aviation aluminum material, and is processed by CNC imported from Japan. DIY：You can simply install it by yourself.
• NOTE : Please calibrate the E-steps from 100 to 139; Please lubricate the gears before first use; for 3d printers with filament detector, as the height of our dual gear extruder may be different from the original one, please print the model to rise up the filament detector to make them at the same height; for Vyper users, please swap the motor wire sequence to make it turn forward instead of reverse.
