You will not be able to attach the gear to the 42-40 motors that don't have the longer center shaft. These use a 14mm (from the raised part of the motor, the circle) shaft and it is not long enough. It will not work without changing the extruder motor. Also, the input fitting will not clear the Ender 3 Pro Z rod...so if that's critical for your install, I'd look elsewhere. **Q: Does this fit on a Creality-6SE printer?** A: yes fits on mine, but i needed to print off a riser pad for the filament sensor. the one i used is called "Creality CR-6 SE filament sensor mount riser with cable holder for dual gear extruder" on thingiverse. but just a quick note, YOU WILL NEED 25-30 MM M3 screws. i picked up 2 at a hardware store but you can also buy them off here on amazon. **Q: Could this work with the longer lk4 pro 3d printer?** A: Thank you for your inquiry. This dual pneumatic extruder can be used on longer lk4 pro 3d printer. **Q: Is there a a version of this that comes with a motor?** A: There is a version that comes with the extruder completely build the carriage assembly and a new hand but I can't remember who makes it it's literally a plug-and-play ## Customer Reviews ### ⭐⭐⭐⭐⭐ A great upgrade for my biqu b1 but needs some config changes and spacer *by on Reviewed in the United States 6 March 2023* I have 4 BIQU B1s and installed these on 2 of them so far. I plan to do the other 2. These are a really solid upgrade. For the BIQU B1, you need to be aware of a couple things:- The esteps will need to be changed. Mine defaulted to 98 on the old factory extruder. (That resulted in 105mm instead of 100mm extruded by the way). The correct estep value for these is 136 for a BIQU B1. You can set this via gcode using "M92 E136" then issue a save with "M500". You can also use the "save to eeprom" in the BIQU B1 menu to save. If you're not comfortable entering console commands you can use the tuning menu in the BIQU B1 and do the calibration then ignore the measurements and just increase the esteps to 136. After that, make sure you use the "save to eeprom" option.- Some slicers add esteps to the gcode. The ideamaker app that comes with the BIQU B1 does this. So you'll have to edit the printer config and go to advanced and change it from 98 to 136. You can open the gcode files with notepad or such and search for M92 and make sure it's E136 not E98 in that file.- You can alternatively do none of the above and only change the value in the gcode from M92 E98 to M92 E136 but this requires editing each gcode file after saving it.- Finally, the printer's filament sensor will be slightly too low when installing the new extruder. Ideally you need a couple more 1/4" spacers and a couple longer M3 screws. What I did is unscrew the two screws on the filament sensor and move it to the left so that the right screw went into the left hole on the holding bracket. Then I just used the right screw to hold the sensor in place. This moved it to the left almost an inch and the filament can bend a little and it works with no other spacers. A better long term solution will be to get some longer M3 screws and print a couple extra spacers. But it's been working as I set it without any additional parts. ### ⭐ Poor quality. Doesn't work. *by on Reviewed in the United States 14 June 2024* I bought two of these. The first one kind of worked kind of fine. The second one didn't work at all.The sleeve on the lever arm is designed to protrude from the body a small amount so that when the screw is tightened, the lever arm will still move. The first one was that way and the lever arm moved freely. On the second one the indented hole that the sleeve sets down in to was not as deep by .5mm as the first one which made the sleeve not protrude from the body. When the screw was tightened, the lever arm would not move.The second problem (with both) is that just below the feed rollers where the filament enters the hole to continue on down the path is poorly designed. The hole is so small that the filament hangs up on the edge of the hole. This makes it impossible to change colors mid print and difficult to even start a print. I think I fixed the problem by using a counter sink to open up the top of the hole and funnel the filament path. Time will tell.Anyway, I returned the second extruder that didn't work at all. ### ⭐⭐⭐⭐ Well worth it - with some work. *by on Reviewed in the United States 10 February 2021* I bought two of these (one for my Ender 3 V1 and one for a V2) and love them.They DO NOT come with any instructions so it’s 100% up to you to install them correctly. Take notes removing your old one as these go together very similarly but there’s a few gotchas. Each kit comes two little brass washers. One (preferably both) of those need to go between the idler gear and the face of the aluminum tension arm. The clearance is too small to fit both, so I decided to file the top and bottom of the idler gear down just a hair so I could get one brass washer above and one one below it. If you don’t install the this at least on the bottom, the steal gear teeth will quickly grind straight through the aluminum and you’ll have to replace it. You will also need to change your E-Steps (called “Extruder transmission ratio” on the the E3V2). There are tons of Youtube videos on this, just make sure when you tell it to extrude 100mm of filament, it moves 100mm or your prints will come out ugly or brittle. After 30 large prints between the two machines, I have no issues extruding and don’t have to worry about anything slipping or breaking. ## Frequently Bought Together - Bigtreetech Upgrade Dual Gear Extruder, Double Gear MK8 Extruder 3D Printer Dual Driver Stock Feeder All Metal 1.75mm Filament Extruder Kit for CR-10S Pro/CR-10/ Ender 3 V2/Ender 3/Ender 3 Pro Series - BIQU Panda Jet Head Cooling Fan Duct for Bambu-Lab P1P/P1S/X1C/X1E 3D Printers Compatible with Stock Hotend Panda Revo/Flow - BIQU Extruder Pulley 36Teeth Bore 5mm Stainless Steel Drive Gear for 1.75mm & 3mm 3D Printer Filament (Pack of 5pcs) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/392335573-n-o-bigtreetech-3d-printer-upgrade-dual-gear-extruder-mk8](https://www.desertcart.com.ar/products/392335573-n-o-bigtreetech-3d-printer-upgrade-dual-gear-extruder-mk8) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-11-11*
