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.
- 【Spring Adjustable Extruder】The extrusion spring tension could be adjusted by tighten the screw,which greatly improves the printing accuracy and feeding issue.
- 【Application】:This all metal dual drive extruder is compatible with Ender 3 V2,Ender 3 Pro,Ender 3,Ender 3 Neo,Ender 3 V2 Neo,Ender 3 Max Neo,Ender 5 Pro,CR10 S series 3D printer.ONLY suit for 3d printers with motor shaft over 20mm,please measure the shaft length before placing the order.
- 5.【Kindly Reminder】:Please calibrate the E-steps from 100 to 139; Please lubricate the gears before first use;for 3d printers with filament detector,as the height of our dual gear extruder may be different from the original one, please print the model to rise up the filament detector to make them at the same height;for Vyper users,please swap the motor wire sequence to make it turn forward instead of reverse

## Questions & Answers

**Q: I have a cr10s, do i need right hand or left hand??**
A: All the ender 3 and cr10 series need the right version!!

**Q: Will this work with anet a8 plus? and what version would i need to buy?**
A: You're having trouble with YOUR extruder, too, aren't you? We all are. They're terrible.

This will work with your printer if you're fed up with their direct drive and you're converting it to use a Bowden tube. Be aware that Bowden tube extruders come with their  own unique struggles, but they're not as nasty as the A8 Plus's direct drive extruders.

Since you're doing this conversion, you'll also need some sort of 24V Bowden-style hotend.

It mattereth not a whit whether you go with the left-hand or right-hand version for your printer; you'll mount it wherever you figure it'll be convenient. If I were you, I'd mount it somewhere left of center, but your circumstances may be different from mine.

While you're at it, you might as well upgrade your linear bearings to polymer, too, and your control board to one of the many alternatives. Whatever you do, don't screw around; replace that power cable NOW before you burn your printer to a crisp! The one that runs from the power supply to the control board. It isn't big enough for that load, and the crimped terminals sometimes catch fire. Replace it with no less than #16 AWG wire.

**Q: Will this fit a Monoprice Mini v2?**
A: It's designed for the Creality CR-10, but it's a fairly safe bet that it would fit any bowden printer that uses the same size motor for the extruder, and the same size filament (The creality uses a 42-40 stepper motor, but many other stepper motors have the same spacing between screw holes).  Depending on the bracket the motor is attached to, it's possible the screws that come with this part might not be long enough, but replacement screws shouldn't be hard to find.

**Q: Is this all i need to upgrade an ender 3 to have a metal hotend for printing petg?**
A: You don't need an all-metal hotend for petg usually. The one on the ender-3 will work just fine. The limit of a ptfe tube is around 240-250. Petg prints with a hotend at 230-250 usually, just make sure the filament you buy isn't one of the odd ones that might need higher temps. If you're worried replace the ptfe on your ender-3 with high grade stuff like capricorn and look for lower temp petg filaments.

### ⭐⭐⭐⭐ 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!
