Micro Swiss Bowden Dual Gear Extruder Compatible with Creality Ender, CR10, CR-10 Pro, CR-10S, CR6-SE, Tornado

The wheel in the arm on mine seized up after less than a year. The $12 cheapo dual geared extruder I had before lasted almost 2yrs. Skip it and buy 2 of the cheapos, and some filament.

I was having problems with extrusion on my ender 5 plus. Soon as I installed this and set everything accordingly done and over. No more problems.

This wonderful product has been the saving grace to hours of troubleshooting, filament skipping and jamming. Best of all its made in the USA. I now know where I will be getting all of my parts from if they have them.

Best upgrade I’ve done so far, however… My Ender 3 Pro came with the extruder stepper motor with a press fit gear, which was a pain to remove, but I was able to use it once I did. I highly recommend buying a stepper motor with the flat shaft if your printer doesn’t have one already. Removing the old gear is not worth the trouble considering a new motor is under $20 from Creality, but if you’re impatient like me, it can be done lol. **if you do decide to use the press fit motor, make sure you don’t over-tighten the grub screw on the new gear. I made that mistake and a crack formed on the gear, I was able to get it replaced though and the new one has been working perfectly for over 2 months.

I have had inconsistent prints for 2 years. I always thought it my tramming was off, the filament was to wet, or my z offset was wrong. I have learned a lot about 3d printing and the fine adjustments one can make to compensate for these issues. I usually get decent prints after a few adjustments. My first layers have always been a bit sheet. Recently, I was having some serious dot dash stripping in my first layer after a filament snag failed a 1.5 day print. I spent a week troubleshooting the issue. I was so frustrated, because all the tricks I had learn to resolve first layer issues were not working. I had one print finally finish and it was a sponge. I crushed it with little effort. I finally took a close look at the stock brass (soft metal) filament feeder gears and noticed a rounding / bending of the teeth. First off, I didnt know the the filament feeder gear was brass, or I would have figured it out sooner. I picked up this bad boy for my birthday, and on my first print, I had the first layer put down so beautifully and so smooth I almost cried. The product is well made and easily put together. TIP: if you use a filament sensor and you print out the adjustment bracket provided by Micro Swiss, you will need to trim the tubing. I think the attached tubing is Capracorn PFTE. It is oil slick smooth. I think will order some as my next upgrade to replace the stock one I have. Micro Swiss has the quality you have been missing. This product will make your prints better.

Less than 3 days of use, not even running 24/7. Grinding noise coming from extruder. Upon further inspection, the drive gear broke off around the grub screw causing it to skip and ultimately allow the motor to spin freely.

I have installed the Micro Swiss dual-gear Bowden extruded on two printers - a Creality CR-10S and my Frankenstein i3 clone. This extruder is a dramatic improvement for both. I recently started printing with some matte-finish /particle-supplemented types of PLA. The standard single gear with passive roller was having a hard time feeding these filaments because they are a bit harder than regular PLA, making it difficult for the standard extruder to grip and feed. Increasing the power to the extruder stepper motor helped a bit. But these filaments really benefit from a dual gear system that maintains a positive grip on the filament, not only because the filament is harder to “bite”, but also because the particles contained inside are more difficult to pass through the standard 0.4mm nozzle opening. The upgrade to the Micro Swiss dual gear extruder solved the problem. It’s very well engineered and manufactured in the USA, very easy to install, and is a great all-around extruder for use with standard and particle-enhanced filaments. FYI - I found a ballpark steps/mm setting of 140 was optimal for both extruders on my machines. That said, this is a great product and money well spent.

This is the right product... If youre looking for an aftermarket extruder, you should be looking for something with dual gears and a notch in the gears for filament location. If you know that much, then youll also know that the next available option is almost TRIPLE the price. Why I picked this one isnt based on price, but due to design. Having the gears open allows for easy cleaning when needed. The hardened steel teeth in the gears will get gunked up with softer materials when the spring tension isnt correct. However, setting the tension is as simple as tuning the grippy knob/nut at the back (easily accessible). The only downside for CR-6 SE users is that you have to print an adapter plate. Its a very simple part, but if youre having issues with your 3D printer, it may be hard to actually print something. Just saying ;) Happy printing!

Easy install and works like a treat. My only real complaint is it can bind up when pulling a lot of filament at once, like using the filament loader function on the community firmware.

Ive tried other extruders and this one is finally a good improvement over the others. Before I installed it I printed two models for comparison after the install. My printer already has many upgrades already so any improvement would be small anyway. But I did notice an improvement at the edges of parts over the stock Ender design. So Id recommend it if you want to add just a little more precise control on the extrusion. The parts are really well machined and the two gears really grip the filament well. The bowden tube is held in place using a brass flare fitting which Id never seen before in this application. It works great but you have to tighten it well so the brass fitting gets squished just like you are fixing a water pipe fitting. Thats the way its supposed to work so nothing is wrong. It wont come off the tube after that so you might want to buy more of the little flare rings for future use, just go to Amazon to buy them.
