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

I got this to replace the stock extruder on my Anycubic Mega S after it accidentally ejected one of its filament guide pieces and started having consistency issues. Almost didn't end up installing it as I found the missing piece and was able to repair it the day before it arrived - but I'm so glad I did. This extruder design address all the major issues I had with the original extruder. It's easier to adjust the tension, it handles a much wider range of filament types (even with a Bowden tube,) and it's built like a tank compared to the original which relied on a lot of plastic gears to work. It only took me about half an hour to get it swapped out, another ten minutes or so to adjust the e-steps to match the new gearing, and I was ready to go!There are a few things you should probably be aware of if you want to use this on a Mega-S in particular. Biggest one is that the tension release is probably going to end up in a slightly awkward place, pointing towards the gantry frame rather than away from it if you put it in the same place as the original. It's not a huge issue for me, but perhaps could have been avoided either with a modified printed bracket or just by moving the motor onto the outside. Second is that the pressure it can apply will end up very different due to the updated gear ratios. I had to up temperatures and decrease speeds slightly to stop it from pushing too hard and skipping with my smaller nozzles. But frankly the improved consistency and the ease at which it handles slick, soft, and flexible filaments is more than worth it. And if that's not enough, you also never have to worry about breaking another pneumatic fitting! Just pair it with some high quality Capricorn PTFE and watch your prints get taken to a new level.

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 didn't 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.

Next time I would probably mount it to a 1/8" plate to mount on the top, but what I did wasn't hard. Mounted easily to current stepper motor and all the holes lined up.... but you have to dremel cut off 1/8" from the provided screws as the holes in the motor are not tapped deep enough. And then mounting to the original mount I used two zip ties. The extruder tubing to the hot end is 1/16 bigger than the ferrule that they give you. Dremel cut to allow it to expand slightly and it attaches firmly. The feed is fantastic but in the opposite direction. Very, very nice that they include a reversing wire!! So easy! Prints so much better!

Best Change to My FLSun Q5 3D printer, once I got the E-Steps setup right with this the prints are MUCH better.

It's nice to get a part that is well made and functions perfectly. The allen wrench they sent actually fits tightly into the allen screw (what a concept). The instructions are well written and correct. They recommended an E-step of 130 but my printer actually needed 140. I'm sure that value varies slightly from machine to machine. HIGHLY RECOMMENDED!

Really good quality but I have the cr10s pro v2. It doesn’t line up with the break sensor so don’t make the same mistake

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 an overpriced Pita. They couldn't give threads on both sides the little machine clip will fall out or doesn't grab the ptfe tube which makes it useless.
