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

Installation took less then 10 minutes and was ready to go. Followed instructions and set esteps to 130 and then did a calibration. Mine was very slightly off and had to adjust to 133.4, but the esteps they give you will work mostly which is good for those who dont know how to calibrate their esteps. Ive not had a single skip/slip while using this extruder when your extruder clicks, its skipping. All and all I would buy it again and again.

This was by far one of the most painless upgrades for my Creality CR-6 SE. What prompted me to do it was the constant issues of the stock extruder clogging up and getting that dreaded popping noise and ruining print as a result. Microswiss includes directions and links to videos to guide you on the conversion. It uses your stock stepper motor and the only thing I recommend is keeping your line break sensor. Clip a piece of filament and put it in the sensor to keep it tripped on and keep it plugged in and tuck it under its original mounting spot. (you will rarely have line break issues). All i can say is I wish creality would use this dual allmetal gear for its BOWDEN setup stock.

A beautiful piece. Vast improvement over the plastic stock extruder. Highly recommend. But follow the instructions.

When I was well in practice of using our new printer I had a lot of frustrating issues. The items and upgrades were brand new so I figured it was me and gave up for a long while. Gave up and purchased this and it solved everything. Now I can smoothly switch filament in the middle of a print with no issues!!

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.

Micro Swiss put a good deal of effort into this design, overcoming pretty much all of the problems I had with the factory extruder on my Ender-3 Pro. First, the gears are much higher quality, and grip the filament better than the stock extruder, and the hardened steel gears will not wear out like the brass one did. Second, they moved the filament path to the outside, away from the Z axis rod (which is why you have to use the included reversing cable for the motor). Third, they constrained the filament path so that you can just insert the filament and turn the knob to load it - no more fidgeting with the filament to get it to go through the tiny little hole in the original extruder. And finally, its aluminum, so Im not worried about the lever breaking. The only concern I had with this kit was the fact that it uses compression fittings for the bowden tube, so if you ever have to replace the tube, youll need the correct size brass compression sleeve. They included a spare, but Id suggest buying a few extras. Also, do not overtighten the bowden fitting or you will compress the tubing and restrict the filament from going through it. Finger tight plus about a quarter turn should be sufficient - if you can still pull the tubing out, give it another quarter turn. Once I got it installed, I just keep the fitting finger tight and it holds the bowden tube securely, but I can still unscrew it easily if I need to cut the end off the filament. Finally, make sure you have the stepper motor with a D-shaped shaft. If you have one with a pressed on gear, youll want to replace it, because the plastic knob will not work with the press fit shaft, and youd need a gear puller to get the old gear off. The Creality motor costs about 15 bucks, which is less than a good gear puller, and makes installation much easier. As for the price, you really do get what you pay for. The cheap clone extruder I installed on my other printer has cost me more in wasted filament than I paid for the Micro Swiss, and I will soon be replacing it with the real deal.

Needed upgrade if you want to start printing with more abrasive filament. Or if you just want a more robust extruder. I will say check your stepper motor before ordering this kit and see if the gear is pressed on or has a pinned on gear. If it’s pressed you’ll have to order a different motor which it tells you what model to order in the instructions before you order this like I did and then have to wait and order the motor also. But it’s a solid upgrade

Good.

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.

Under 300 hrs on it so far but its running great
