Redrex Dual Gear Ender 3 Extruder Metal Drive Feeder Upgrade for Ender 3 V2,Ender 3 Pro,Ender 3 Neo Series,Ender 5 Pro,Ender 5 Plus,CR10,Vyper 3D Printer TPU Filament Support(Motor Shaft>21.5mm)

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!

As the title suggests, picked one of these up as the motor previously seemed to be slipping when filament was being fed in, jumping back a few teeth on the filament. So first job was to swap the motor, all good, swapped the filament feed but then realised I need to print a riser for the filament detector. So carried on with just the motor swap, painless, used current filament feeder, and then the motor was jumping just the same.Found that inside the filament spool there's 3 'spots' from where the core was plastic injected/mouded from (small sprue points), causing the spool to 'pull' the filament which was causing the jumping. Current solution? Easy... get a ziplock bag and double sided tape, 'coat' your spool holder with the bag (tape to spool holder, then wrpa the bag onto the tape) which creates more slip on the core, making it easier to slide as the feeder pulls the reel. So far so good, will look into riser printing next, will need some longer screws though so i can mount properly. New feeder does look pretty decent with double gears instead of gear and bearing wheelWill report more when I do the next stage but looking more hopefully so far

Sadly in my use case, the extruder eventually eats itself due to the washer being too small on the shaft. Overtime it basically generates heat and the metal is basically cheese so as you can imagine the cheese eventually melts and the washer starts eating away at the frame of the extruder.This one lasted me about 6 months, printing maybe 5 hours per day.Used on a Voxelab Aquila, prints lovely whilst it lasts, but these things shouldn't really be a consumable item if constructed properly. I've had these without the so mentioned 'washer' and they last about the same amount of time. I think I'll stick to a BMG or Titan. Shame as the other redrex titan and standard one gear extruder work great and have lasted since installation on my other printers.The only reason this still remains 4 star is that the customer services received was excellent, communication was good and issue resolved to my satisfaction.

I know this subject can be quite controversial but I find that these extruders are a simple cheap upgrade that can improve print quality. My own experience is that when I have tried these on printers that have the original single gear wheel and suffer printing issues these can make a significant difference.Yes there are better more expensive solutions but looking at cost vs benefit and the fact that its a cheap way to explore whether its your extruder causing problems. I have a couple of printers running these regularly and for me they have improved print quality a lot. I also keep a spare in case I end up upgrading another printer or fixing a fiends.

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.

Terrible! DON'T WASTE YOUR MONEY!I'm working with an Ender 3v2.Bought it to replace one that started skipping. This lasted a couple of weeks before it failed and started skipping. The fit wasn't great, couldn't put the knob back on as the gear had to be right at the top of the stepper rod.

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)
