Creality Extruder Kit (Red Double Gear)

The latest extruder from Creality with the dual extruder drive gear based on the Bond-Tech extruder gears.  This extruder is featured in the Creality CR-10s Pro and Max printers.  It uses a NEMA 17 stepper motor (sold separately) to drive the extruder and is designed to drive a Bowden hot end.  The dual gears have an increased contact area driving the filament over a single extruder gear, which result in an increase driving force delivered by the extruder.  This makes it a very versatile setup to be used on various printers. 

PLEASE NOTE:

• The extruder is designed to be mounted with a 3mm plate between the motor and the extruder.  This is the frame of the printer on the Creality printers.
• It is recommended that the extruder stepper motor should have a shaft length of at least 20mm (Stepper 42-48).
• The grub screw fixing the extruder gear onto the motor shaft is designed for a D-shape motor shaft with a 3.5mm flat.  If the motor used has a smaller flat the grub screw will need to be filed down. 

PERFORMANCE SPECIFICATIONS:

• Works with 1.75mm filament
• Suitable for ABS, PLA, Nylon, Flexible, T-Glass, Wood filament, PVA and PC filament.
• Adjustable spring preload on filament.
• Compact design.
• Firmware configuration: 160 steps/mm if used with a 1.8deg/step motor and 1/16th micro stepping.
• Please note: This kit does not include a stepper motor which will be required for operation (Stepper 42-48).
