Conventional extruder usually only has one drive gear and a guide bearing, which causes the lacking of griping force with the filament and lead to bad printing quality. Two drive wheels grip the filament from each side, providing a robust and reliable feed into the hotend. From common materials like PLA and ABS to flexible filaments like TPU or TPE, the dual-drive gears of the Extruder can deliver a consistent flow of filament in either direct drive or Bowden configurations.


The Extruder is designed with a opening knob on the side that holds one of the dual-drive gears. This knob is closed with a spring-tensioned thumbscrew. This thumbscrew enables an exact tension of the drive gears for the proper hold on the filament, with the ability to release the strain and simply load or unload the filament.

All you need to do is pull away from the extruder so that the spring will compress just enough to release the pressure on the material, letting you easily feed it directly into the hotend.


Bowden or Direct drive? The extruder is constructed for either setup with a mounting slot on the bottom for an E3D hotend or a groove mount for Bowden tubes. The light-weight style of the Dual Drive extruder makes it useful for direct drive configurations. This is because it helps to reduce tool head weight. Having a lighter head means the printer can move quicker while not sacrificing exactness or print quality because of wobble.

DUAL DRIVE Extruder Installation

It’s a simple way to install the dual drive extruder, it only takes 6 steps. 1. Remove the original extruder. 2. Remove the old gear from the motor. 3. Replace it with the new gear and lock the screw, watch out the direction of the gear. 4. Place the motor back carefully. 5. Place the extruder on top. 6. Fasten the three new bolts we provided.

Calibrating the Dual Drive Extruder

Standard Marlin Control Panel

You can do this by Control => Motion => Steps /mm => E Steps /mm and enter the value 415. Then try to print a model, if you see hotend under extruding or over extruding, please do a calibration and adjust the E Steps /mm accordingly.

Other Printers

Please contact the printer provider to see if you can change the E steps/mm.


Instead of pulling from the Inlet of the extruder, pull from the outlet. This is to help prevent the filament from sticking in the extruder. When you do a cold pull, the filament is usually more substantial at the tip. So, if you pull from the PTFE tube side, this will take the thin side of the filament through the extruder resulting in an easy atomic pull and an unblocked nozzle.
