## Description

desertcart.com: Bigtreetech Upgrade Dual Gear Extruder, Double Gear MK8 Extruder 3D Printer Dual Driver Stock Feeder All Metal 1.75mm Filament Extruder Kit for CR-10S Pro/CR-10/ Ender 3 V2/Ender 3/Ender 3 Pro Series : Industrial & Scientific

Review: Absolutely kills it. - To get it out of the way first, yes, as everyone else has mentioned... No instructions. However, if you pay attention when you are removing your old extruder, this is a straightforward process. I have been trying in vain to get a large nozzle (1.0 mm) to work on my ender 3 pro for rapid drafting. The stock extruder laughed in my face and skipped like a record when I tried to print with the 1 mm. I installed this extruder, not really expecting that much of a difference, but I had tried every other suggestion for fixing extruder skipping. Slowed the print down, adjusted up my zed offset, changed stepper motors, checked stepper voltage, all that crap. Long story short, I installed this guy and have run a few tests. I started with a layer height of .6 at a print speed of 30. No problemo. I was surprised. So I jumped it up to the .8, same speed. No issues. I went bananas and jumped it up as far as I could possibly need it to go: 1 mm layer height at 50 mm/s (my usual speed for PETG). I'll note here that I ran it at a 1.1 layer width as well. Holy crap, it ran it no problem. You can watch your spool as the life drains out of it at that height and speed, but it does an amazing job now. Just from the extruder change. Buy it. Buy it now. BTW, you can do a layer height the same as the nozzle, but you need to know how to set your slicer. Most people recommend no more than 75 - 80 percent, and that's perfect if you don't want to muck around too much.
Review: Definite upgrade. - Much better than stock. Very simple install that cuts down on clogging and improves overall print quality. Bigtreetech just makes great stuff.

## Features

- Upgraded Dual Extruder: Dual gears and dual pneumatic combined extrusion structure, large extrusion force, enhanced feeding intensity, ensuring smooth feeding. The double gear rotation design locks the filament, which is beneficial to improve printing quality and reduce filament slipping, high-speed extrusion or retraction, better pressure to push the filament into the printer, less easy to lose steps, faster printing speed
- Compatibility: Double gear mk8 extruder, perfect replacement for 3D printer CR-10/ CR-10S/ CR-10S Pro/ Ender 3 (initial version)/Ender 3 v2/Ender 3 pro/Ender 5/Tornado, etc. 1.75 mm filament (Set only for 3D printers with motor shafts exceeding 20mm, please measure the shaft length before placing an order.)
- Stable and Durable: All metal aluminum alloy, high quality double gear extrusion, compared with ordinary plastic drive, this high aluminum metal filament extruder is stable and durable. The idler gear has been upgraded with a brass washer added between the stainless steel gear and the aluminum housing, so the gear does not collide seriously with the housing, which helps reduce stock extruder wear
- Adjustable Spring: The tension of the extrusion spring can be adjusted by tightening the screw, which greatly improves printing accuracy and paper feeding problems. Strong extrusion end spring enhances feeding strength and ensures stable pushing of filaments into the hot end of the printer. Suitable for most types of filament, such as ABS, PLA, TPU, PTEG etc
- Imported Materials: The 3d printer dual extruder material is made of brand new imported aviation aluminum material and processed by CNC imported from Japan. The kit does not include the stepper motor, motor bracket and instructions, we need to make them ourselves. If you need some installation help, there are video introductions online, and you can seek our technical help at any time

## Questions & Answers

**Q: Does this work with newer 
Ender 3 Pros?**
A: Yes...and no.  You will not be able to attach the gear to the 42-40 motors that don't have the longer center shaft.  These use a 14mm (from the raised part of the motor, the circle) shaft and it is not long enough.  It will not work without changing the extruder motor.

Also, the input fitting will not clear the Ender 3 Pro Z rod...so if that's critical for your install, I'd look elsewhere.

**Q: Does this fit on a Creality-6SE printer?**
A: yes fits on mine, but i needed to print off a riser pad for the filament sensor.  the one i used is called "Creality CR-6 SE filament sensor mount riser with cable holder for dual gear extruder" on thingiverse.  but just a quick note, YOU WILL NEED 25-30 MM  M3 screws. i picked up 2 at a hardware store but you can also buy them off here on amazon.

**Q: Could this work with the longer lk4 pro 3d printer?**
A: Thank you for your inquiry. This dual pneumatic extruder can be used on longer lk4 pro 3d printer.

**Q: Is there a a version of this that comes with a motor?**
A: There is a version that comes with the extruder completely build the carriage assembly and a new hand but I can't remember who makes it it's literally a plug-and-play

### ⭐⭐⭐⭐ Well worth it - with some work.
*by J***D on February 10, 2021*

I bought two of these (one for my Ender 3 V1 and one for a V2) and love them. They DO NOT come with any instructions so it’s 100% up to you to install them correctly. Take notes removing your old one as these go together very similarly but there’s a few gotchas. Each kit comes two little brass washers. One (preferably both) of those need to go between the idler gear and the face of the aluminum tension arm. The clearance is too small to fit both, so I decided to file the top and bottom of the idler gear down just a hair so I could get one brass washer above and one one below it. If you don’t install the this at least on the bottom, the steal gear teeth will quickly grind straight through the aluminum and you’ll have to replace it. You will also need to change your E-Steps (called “Extruder transmission ratio” on the the E3V2). There are tons of Youtube videos on this, just make sure when you tell it to extrude 100mm of filament, it moves 100mm or your prints will come out ugly or brittle. After 30 large prints between the two machines, I have no issues extruding and don’t have to worry about anything slipping or breaking.
