Specification Brand : HoCenWay BulletPoint : EVD0000E50 controller for stepping electronic expansion valve driver. BulletPoint1 : The Gearing Ratio is 3:1, High precision, we recommend E-step value 385. And to adjust the tightness of thumbscrew to fit the printing. And The gears can be suitable for all 1.75mm filaments even flexible filament like TPU. BulletPoint2 : 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. BulletPoint3 : The extruder is constructed for either setup with a mounting slot on the bottom for V5 V6 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. BulletPoint4 : Please compare your printer extruder position dimensions with our extruder size to confirm it can install or not to your printer before ordering.

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.
