worked like a charm
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!

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.

Great but not compatible with modern Ender 3 Pro models
The most recent Ender 3 Pro models supplied by Creality themselves have a gear crimped to the extruder motor shaft. The shaft itself is actually shorter even if you tried to remove the gear with drilling, it wouldn't fit this product - or any other extruder for that matter, as Creality have changed the default size.The solution for me was to spend another £20 on an official motor which comes without the crimped gear and a longer motor shaft, there is no other solution other than to but another stock plastic extruder arm which are prone to breaking (as happened in my case originally).I'd definitely recommend this product as it does an excellent job, but they really should advertise that it is not compatible with Ender 3 Pro without first upgrading the extruder stepper motor.

Works with FLSUN Q5
TLDR; works great on FLSUN Q5 after upgrading A4988 driver.I took a gamble to see if this would work for my FLSUN Q5. I wasn't a huge fan of the default Titan (like) extruder. It would often fail to grip different filaments and I was constantly adjusting it.The gamble has seemed to pay off. This fits perfectly!However, after fitting I found the stepper motor would slip significantly, even after calibrating E-steps, making an awful noise. No amount of checking the bowden tube, adjusting print speed, feed/flow rates seemed to help, unless I went very slow. So, I had the genius idea to check the Vref on the A4988 driver as it simply wasn't keeping up. Thankfully, I forgot to put on my glasses and accidently shorted it. This meant I needed to order a TMC2209 replacement driver. I used the BIGTREETECH KINGPRINT TMC2209 v1.2 which work great.After putting on my glasses, I dialed the Vref to 1.273 Vdc giving 0.9 Amps as per stepper motor spec. Note: This is very close to factory default, so you could just drop these in. I also insulated to Vref/Diag pins as they're pretty close to the capacitors on the MKR Robin Nano v1.2 board in the FLSUN Q5.After calibrating the E-steps I got approx. 147, slightly higher than the 100-139 specified.End result is a super quiet, smooth and consistent extrusion. So, I am pretty pleased so far.

So much better than stock
I don't tend to replace things until they're broken, but I would actually recommend people replace the extruder on most budget printers, what they give is you is made of plastic and doesn't cope well with the forces involved.To be fair, the original did last a few years with light use. Then suddenly all my prints started failing and I couldn't work out why. Finally tracked it down to a hairline crack in the extruder - after checking almost everything else first.Being metal and dual, it really grips the filament and doesn't let go. You do need to make sure it's very well aligned, or you will shave your filament, or grind it into dust. But once setup, you can forget about it. So much more reliable, no more slipping, no more under extruding!

Under extrusion...... No more
I had a problem with the prints looking like puff pastry when I wanted short crust. I tried drying the filament and different filaments, still no joy. I decided to try this dual gear one. It's really good value to as it's a cheap upgrade.Installation was a bit fiddly and needs fine tuning to perfect it, it does make it worthwhile. It improves retraction and stringing, plus it looks amazing in red.NOTE - you will need to adjust to pressure to prevent too much grinding of filament, if there is too much you can cause issues with the printerHowever, if you want a filament sensor, it won't fit to this without adjustment, and printing a stand for the sensor.All in all, it's a must have if you have an Ender 3 V2 (mine is a neo)

No in struction
The one I bought looked like it had been used as some of the coating was worn where screws and bolts would be. The unit came completed disassembled and with no instruction so took longer to assemble than it really should have. It works fine and is doing the job so it is good overall. Shame about the previous points mentioned though

Good solid dual gear extruder
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.

Sehr gutes Upgrade für meinen Ender 3 Pro
Hab meinen Ender 3 Pro von dem serie solo Gear Feeder auf Dual Gear aufgerüstet. Würde ich auf jeden Fall weiterempfehlen:Aufbau:ein bisschen knifflig mit der Feder, aber es machte schon beim Aufbau einen sehr soliden Eindruck. Sonst eigentlich ganz einfach - alten Feeder abschrauben, neuen dranschrauben und Filament durchführen und schon ist es startklar.Anwendung:Auch nach längerem Einsatz muss ich sagen, ich bin mehr als zufrieden. Selbst bei feineren Drucken, wo der Feeder sehr präzise arbeiten muss und auch oft das Filament vor und wieder zurückschieben muss, macht der dual Gear Feeder sehr gute Arbeit.

Para que siga trabajando eficiente su impresora
Que lo utilice para una impresora 3D marca Voxelab y quedó muy bien

Great upgrade and easy filament change/feeding.
Great extruder, using two gears instead of a bearing, the alu housing also is a big stepup from the original plastic and now the filament hole is also easier to find and put new filament in.

Works Great - Don't forget to change E-Steps !
Works really well with my Ender3 V2, the dual gear delivers filament really well.Only issue I had weren't cause by the product : I forgot to change my e-steps. This resulted in extremely weak prints. Of course, it extruded 6,6cm of filament when I asked for 10... So don't be like me, and immediately calibrate your e-steps after installation!
