Micro Swiss Direct Drive Extruder for Creality CR-10 / Ender 3 Printers

Used this for about a month with constant print failures due to leaks at nozzle. Tried all correct methods for securing nozzle, losen a turn and then tightening heat break - BUT!!! The heat break is then tight against the block - and when hot this is loose and leaks (both nozzle and heat break fully-seat in heat block). Bought the clone - was able to secure heat break and nozzle correctly (shows small gaps at both heat break and nozzle) and no longer have leaks. Would like the option to at least buy a heat break with sufficient threads / until then I’ll just buy clones.

Installed this for my modded Ender 3 Pro. The extruder itself is fine but the hotend sucks. It has no supporting screws so it is free roaming, and also leaks filament constantly. For something that is nearly $100 Id expect much better. Update: Microswiss offered to send a replacement hotend and was very helpful when I contacted them. Everything works great!

Easy install. No tweaking required. Fast setup. No complaints apart from how it brings your nozzle a little further forward. 100% would recommend. MUST HAVE!!

Got this for my Ender 3 Pro. Followed some of the instructions for a bit then I realized that if I did the assembly according to their pdf everything would be messed up. Had to guess how things come together (Some, not all.) The parts included are for the extruder stepper motor which is depicted (in their install) as having an easy to remove head. Well... After bending the shaft trying to get the sob out, I can tell you it is not easy to do it. So yes, you will have to modify your stepper motor, there is none coming with this kit. I believe this will be a good upgrade for my printer but the documentation, the main product picture (2nd picture is accurate) depicting a stepper motor are all garbage for the pro version ( hey, docs may be great or other printer types). So, is it a good kit? Sure looks like that. Will update but the -1.5 stars are just for my case of not being satisfied with price/product ratio ( no stepper motor - which is basically the fine print but it is there in the description) not satisfied with documentation and not happy with having to destroy a stepper motor that came with the printer or buy a separate one with the naked shaft. Update: NOT their fault since instructions are for Creality extruder motors replacements that have a different shaft than the original one. So be careful getting the gear out or save yourself a headache by purchasing a replacement motor. As can be seen in the pictures one motor has a crease while the original is round.

My prints were mostly coming out fine, as long as I was using PLA. But once I started using PETG, I started having issues, mostly just prints not completing. After this upgrade, I can start a PETG print and just walk away. Adhesion is perfect, and the rest of the print finishes flawlessly. Make sure to adjust your refraction settings to 1.5mm as the instructions say, and you should have no issues.

I bought this hot end kit to upgrade an old Geeetech A30 printer I have that was well used and abused. The quality of the parts in this kit is top notch! Very high quality machining on all of the parts in the kit. When properly installed and calibrated (!!!) this kit will produce outstanding printing work! Zero clogs or other issues in several very large prints that I have done lasting well over 100 hours each!! Being able to reliably run an entire roll of filament without issues is just fantastic! I couldnt be happier with my purchase. Just to be clear this item was purchased with my own funds and I was not given anything for this review, Im just a happy customer. If you want to take your 3D printer hot end to the next level this kit could be just what you need.

I purchased this as an Upgrade to my Ender 3v2 hotend and extruder. First, I have never gotten a print any better than what the stock hotend and extruder gave me. Actually, quality has decreased. It has gotten better, but I have spent HOURS tweaking settings trying figure out what this thing wants to see. I lost ALL adhesion on first layer (after releveling the bed and and resetting Z offset). Swapped back to stock and no issues with adhesion. Not sure what thats all about, but was a huge struggle. Had to go to a glue stick, then to PEI sheet which is awesome. Then the extraction settings... Nowhere close to the recommended setting from MicroSwiss. I am running a fifth of their recommendation for distance and at faster speeds. It is very well made- no question. I just wish I hadnt gone this route. Caused a lot of needed frustration and expense with wasted prints. I was ready to throw the MicroSwiss away and go back to stock. Probably still should since I get better results. I just hate spending that much money to take a step backwards in quality.

This Microswiss Hotend and extruder is one of the best upgrades for your printer.

be very very careful cleaning this hotend! I purchased it less than 3 months ago and have stripped the grub screws. it is junk now. cant find anything about a warranty on amazon. Im going to look at the MS website. probably doesnt cover my issue though

While this extruder looks high quality with beautifully machined and polished aluminum, I must say Im not impressed with the design. It consistently has TERRIBLE jamming problems when printing TPU, which is one of the filaments direct-drives are supposed to be better at. It also tends to conduct a lot of heat to the motor, as its mounted directly to the aluminum plate which gets quite hot. There really should be a thermal barrier. Overall I am not impressed given the very exuberant price. The OMG extruder is less than half the price, is more configurable, and performs much better.
