All-metal aluminum alloy, diy aluminum block, you need to be assembled it by yourself Package Included: 1 x CR-10 Upgraded dual gear extruder kit Review: 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: 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. ## Features - ❤【UPGRADE DAUL GEARS】Double-gear and double-pneumatic joint extrusion structure, high extrusion force, enhancing the feed strength , ensuring smooth feeding, better pressure pushes the filament into the printer, not easy to lose steps. - ❤【COMPATIBILITY】Perfect replacement for 3D Printers CR-10/ CR-10S/ CR-10S Pro/ Ender 3/Ender 3 v2/Ender 3 pro/Ender 5/Tornado, etc. For 1.75mm filament. - ❤【STABLE AND DURABLE】All-metal aluminum alloy, High quality dual gear extrusion, Compare to the normal plastic drive, this high aluminum metal dual gear extruder is stable and durable. - ❤【IMPORTED MATERIAL】The product material adopts brand-new imported aviation aluminum material, and is processed by CNC imported from Japan.

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 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by D***. on 22 February 2021* To get it out of the way first, yes, as everyone else has mentioned...
