Dual Gear Extruder with Nema 17 Stepper Motor Kit

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.

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

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!

Great price, simple instructions and installation, only had to remove old extruder and install new one then change Esteps up from 93 to 145 Fit perfectly and had zero issues since installing related to extrusion

I recently upgraded my Ender 3 with the Redrex Dual Gear Ender 3 Extruder Metal Drive Feeder, and I must say, this upgrade has been a complete game-changer for my 3D printing experience! The quality and performance of this extruder upgrade have far exceeded my expectations. First and foremost, the dual-gear design of this extruder provides superior grip and control over filament feeding, resulting in smoother and more consistent extrusion. This has significantly improved the overall print quality of my Ender 3, allowing me to achieve finer details and cleaner prints with ease. The metal construction of the drive feeder not only adds durability but also enhances the reliability of the extruder, ensuring long-lasting performance without any issues. I can now print for hours on end without worrying about filament slipping or jamming, thanks to the robust design of this upgrade. Installation was a breeze, with clear instructions and a user-friendly design that made the process smooth and hassle-free. Within minutes, I had the Redrex Dual Gear Extruder installed on my Ender 3, ready to take my 3D printing projects to the next level. Overall, I highly recommend the Redrex Dual Gear Ender 3 Extruder Metal Drive Feeder upgrade to anyone looking to enhance their Ender 3. The improved performance, reliability, and print quality make this upgrade a worthwhile investment for any 3D printing enthusiast. Upgrade your Ender 3 with this extruder, and you won't be disappointed!

Solid little package. Instructions were less than obvious on how to put it all together but it wasn’t too complex in the end. Great care is needed in alignment though to make feeding new filament work. My printer has klipper installed and it was easy enough to calibrate the extruded. The filament comes out with fine even and clean teeth marks on two sides. Made a clear difference from the plastic stock extruder.

Excellent item, installs very easily and is much better than the plastic oem part.

It's shredding itself apart. Stock extruder had lasted 3 years and started skipping so thought I'd treat myself to an upgrade. This has literally shredded itself apart and is now worse than the one I needed to replace. I've learnt my lesson-buy cheap means buy twice!
