Review: Fixed issue with under extrusion - Had my ender 3 v2 for about 3 years, and suddenly mid print the printer stopped feeding filament into the extruder properly. It made the print very fragile and much less dense. I noticed that if I pushed the filament into the stepper motor it would print normally, but as soon as I stopped manually feeding it the print would become fragile again. I disassembled the stock part to find there was a crack in the plastic and it want pinching the filament correctly while feeding. This replacement is much stronger, made from metal, with dual gears for gripping the filament. Easy swap out, takes about 5 mins, and immediately fixes the issue. Good price and good quality.
Review: Very Robust and Needed Upgrade - Couldn't quite put my finger on why I was not getting good results with my prints, then I watched a youtube video on how this could possible be the cause. So, purchased this with the stepper motor (glad I did) and fitted it with little effort (while watching a 'how to' video on youtube). Instruction that are included are not good. The thing to bear in mind is that you must calibrate it once finished and this process is straight forward but, does take a few minutes to achieve good results (the video I watched was by 'Casual DIY'). I have had much better prints since fitting this. It seems to be very well made and has been accurately manufactured to fit, all presented in good packaging

## Features

- 【Double Gear Extrusion Mechanism】The filament is gripped by the dual drive much more firmly with less deformation, so it doesn't jam as much in the tube, nozzle or hotend.
- 【Upgraded Idler Gear Design】This idler gear is upgraded with two washers on both sides, so the sharp gear will NOT ride against the bottom of the arm or chew it up.
- 【Application】This all metal dual drive extruder with motor kit is compatible with Ender 3,Ender 3 V2,Ender 3 Pro,Ender 3 Neo,Ender 3 V2 Neo,Ender 3 Max Neo,Ender 5,Ender 5 Pro,Ender 5 Plus,CR10 Serie,Voxelab Aquila 3D printer.
- 【High Torque Motor】The Nema 17 stepper motor provides 1A 40Ncm/57g.cm^2 in holding torque which helps to improve the motor's stability.Notice:for Non-Creality users,please swap the motor wire sequence to make it turn forward instead of reverse
- 【Kindly Reminder】:Please calibrate the E-steps from 100 to 139; Please lubricate the gears before first use;for 3d printers with filament detector,please print the model to rise up the filament detector to make them at the same height;

### ⭐⭐⭐⭐ Nice. We’ll made.
*by G***T on 12 September 2023*

Got this to help with consistency. If you are mounting it on top of motor as I did After running for some time “ on PETG l found that the feed wheel was skidding. It took me a few attempts befor I realised that the unit was worming up due to the stepper motor running at 140 steps per inch instead of 100 Steps. I resolve the problem by creating a small heat brake under the feed mechanism. Ps I am running in an enclosure!
