Bowden Extruder Upgraded V3.0 Dual Drive Gear High-Performance Parts for CR10,Ender 3 Series,Anycubic Mega S, I3 Mega Chiron,Tevo Tornado, Wanhao D9, Anet A8 E10 and Prusa I3 DIY 3D Printer

Exactly what I was looking for

Cheaper but work the same to me than original brand. Recommend highly!.

Update: I no longer recommend this.I have a similar problem to the Prusa issue #602. It's an inconsistent extrusion that makes prints look kinda bad. The pictured model is from MihaiDesigns to show this issue specifically. It also might look like other things, so test with this to see on yours.I'm still assembling my hotend and haven't tested printing quality. I'll update later with the results.Currently I've ran into some issues with getting a direct drive configured cold end to fit properly. The clip in the cold end hits the inside of the extruder body and needs to be removed, but doing so does not support the PTFE tube correctly so filament can feed well. I ended up using a bowden setup cold end and a printed spacer to center the ptfe tube.

works great with pla, ninjaflex, cf nylon on ender 5 printer in direct drive. previously tried the winsinn dual gear extruder and it is trash compared to this. using it with a pancake stepper and it takes around 424 steps/mm in my setup. construction seems perfectly solid and everything lines up. using it with a printed mount bracket from hero me gen 5 on thingiverse, where it is only fastened by 3 screws thru a vertical spacer to mate with the stepper motor. because of this it was initially pushing up away from the mount when extruding, which resulted in puzzling print defects. eventually noticed this movement and strapped it down with zip ties and everything is perfect now.

Update:My mistake. Apparently I had the drive gear tension screw too tight. It prints Zyltech TPU (seen in the second photo) wonderfully once I dialed in the tension. The misaligned guide bearing was an issue at first, but most makers will not have a problem correcting that. Definitely worth what they're charging.Original Review:The gear on the tension arm has way too much play so I had to secure and align it on either side with small washers. Even then it still will not print my 90 hardness TPU without it tangling in the gears and jamming, which is what I bought it for it the first place. On the plus side I’ve seen a huge improvement in my PLA and PETG print quality. It also works well with the uSongShine pancake steppers that are so highly rated on Amazon. Mine is probably just a QC issue. Maybe you’ll roll the dice and get one of the great ones mentioned in the other comments. As for me, I’m done with cheap clones.

First off, I bought this because it was very affordable, and it doesn’t have a chance to short out my board.In the past, I purchased 2 SIMAX3D heated beds that BOTH fried out TWO SEPARATE boards. Because of that, I won’t buy ANYTHING from SIMAX3D that will connect to my motherboard. Now this, luckily, doesn’t need to be wired to my board, so I bought it. It works fine, although it had some grinding when I first set it up, but then it got much smoother after it ran for a few hours. Now it’s running smooth, so I’ll keep using it. But every time I can, I’ll let people know that I have lost 2 different motherboards to 2 different SIMAX3D heated beds (I believe it’s the thermistors or the soldering connections, but either way, bad heated beds!). I had posted a review with a video on the heated bed’s actual product page, but it miraculously isn’t there anymore 🤨🙄🤷🏼‍♂️So to recap, this extruder is fine, but beware of other SIMAX3D products.

I am very impressed! I previously had a Winnsinn dual gear extruder on a direct drive mount on my Ender 3. I swapped to this extruder along with a pancake stepper motor, and the weight saved is huge! I'm still dialing in the steps-per-mm on different types of filament, but using this extruder and a shortbody motor made by stepperonline, my average steps are around 415. Use this as a starting point if using a similar setup.I'm not in love with how fiddly it's made filament changes, but for the price, this thing is pretty great.

Tried to install it on my Ender 3, and it ran into the Z screw. If I were to shave the plastic down, the Z screw would then hit the drive gear. This extruder is entirely incompatible with the Ender 3.I had to reverse the motor and run it backwards, which then promptly broke the Bowden connector since it's normally the inlet and not meant to take the pressure of extrusion. The replacement connector is literally more expensive than this whole extruder, so I'm just going back to my old one and avoiding this whole lineage of dual-drive extruders.But, for what it's worth, in the short time it WAS working, my E-steps were perfect at 425.3, so if you do get one of these for your non-Ender machine, start there. Yours may very a bit though since I was running mine in reverse.
