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

I cant believe it. I was shown how much difference an extruder can make. Yes Im a newbie, 8 mos. in. After a serious filament clog my stock plastic extruder started talking to me. Click, clack, what the heck was that, kind of noises. So I ran across this bad boy and made sure it would fit my Vyper. After a seamless installation I am beyond impressed by the results. Its like a new printer. It fits like a glove and machined to perfection. When it comes to moving filament NO HESITATION. I went from 425 esteps to 138. Extruder runs quiet as a mouse. NO DRAMA. Follow the instructions, however, in my case, when the wire harness was used it caused the motor to run backwards. Leave it alone on the Vyper, it works fine. But of course check it. I went with 3.5 mm retraction distance at 45mm speed. Left the flow alone, the test cube was perfect. Prints are awesome. I cant say enough about this thing.

Does a great job and easy to install the instructions are really straightforward did have to calibrat my steps after install but worth every penny.

Works absolutely great, was the key to first layer sticking problem I had

Edit: 04/12/2022 After some time trouble shooting and getting spare brass sleeves, and somehow getting them to fit the inner diameter of the bowden and the connector, I would recommend this over others, but at the same time, I hate it. Major design flaw, the bowden tube connector part has a outer screw in with a piece used to hold the bowden tube in. If ever you have a jam and need to replace the bowden tube, the screw in stopper will be permanently stuck to the old bowden tube. Making it impossible to use a third party screw in stopper due to it being a outer screw in rather then an inner screw in. The product is great and all, but it is a one time use for a bowden tube.

Got my E5+ a few months back. Research had informed me that the stock plastic extruder was a weak point. Decided to get a replacement right off the bat. I wanted a dual gear Bowden and not red, so this fit the bill. :) I hadnt gotten around to installing it yet when my stock extruder broke after just three weeks. Realized then that I had a stepper motor with a pressed on gear. I could have muscled the gear off and milled a flat onto the shaft for the set screw in the new gear, but I just ordered another stepper instead. Theyre cheap and it doesnt hurt to have a backup. An E5+ will need a printed bracket to reposition the stock filament runout sensor if you want to keep it. If you dont have another printer and havent printed one before you need it, you can just stick a piece of scrap filament in the sensor and lay it aside while youre printing the bracket. The listed 130 steps resulted in a good bit of underextrusion. Based on measurements and the calculations on the Teaching Tech calibration web site, 137 is the proper number on my machine. Overall, a very well-made piece and a good upgrade, even over the metal extruders on some machines.

On one level this extruder is silly... for $50 more you could move to a direct drive system and be done with it. But if you have an older 3d printer that you are largely happy with and just want easier changing of filament or better control of extrusion, this is about as good as you are going to get. Everything on it from the tension adjustment to the piece of tubing which guides in new filament just makes more sense on this extruder than it does on any other. Really this extruder is a critique of every other extruder I have ever used. Really it works great. For example I am printing out some vase-mode models while intentionally using over-extrusion (0.6mm line width through a 0.4mm nozzle) and it does not miss a beat at the printers standard speed. It just happily pushes filament. Installation is easy except for cutting a notch in the Bowden tube. Some kind of guide or jig would have made that a lot easier. That being said, I did manage to do it with filament snips, so I cant really complain. Combined with a BLTouch and OctoPrint, I have removed all the things I found annoying about 3d printing and am enjoying everything much more. On the other hand, for the amount I have spent on upgrading my Ender3 Pro I probably could have just bought a better 3d printer to begin with!

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.

Easy installation

Easily installed on anycubic kobra max. set up and installation was a breeze. amazing performance vs the stock extruder by far.

This adds a great deal of precision to filament metering, which contributes to better print quality. Worth every penny, and the effort to install it!
