About this item

• 【Double Gear Extrusion Mechanism】The filament is gripped by the dual drive much more firmly with less deformation, so it doesn't jam as much in the tube, nozzle or hotend.

• 【Upgraded Idler Gear Design】This idler gear is upgraded with two washers on both sides, so the sharp gear will NOT ride against the bottom of the arm or chew it up.

• 【Application】This all metal dual drive extruder with motor kit is compatible with Ender 3,Ender 3 V2,Ender 3 Pro,Ender 3 Neo,Ender 3 V2 Neo,Ender 3 Max Neo,Ender 5,Ender 5 Pro,Ender 5 Plus,CR10 Serie,Vyper,Voxelab Aquila 3D printer.

• 【High Torque Motor】The Nema 17 stepper motor provides 1A 40Ncm/57g.cm^2 in holding torque which helps to improve the motor's stability.

• 【Kindly Reminder】: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

• Attention: Only suit for Motor shaft over2cm
