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

Excelente inversión es seguir el manual para instalar y funciona perfecta

Fixed a good bit of my issues with the stock extruder! Be aware that with the extra weight you may have to look into getting dual Z, just a little deeper into the rabbit hole. All in all, solid upgrade!

Updated review. I initially posted a negative review as it seemed no matter what I did I was getting blobs on large flat areas. after about a month of fettling, I now am 95% of where I was with a stock Ender 3 V2. Most of the problems were me. It is now my belief that due to the additional weight on the gantry, you NEED to go through your printer again and re-check every single nut and bolt and eccentric nuts, as the setup is less forgiving than stock. Make sure the right side of the X-axis isnt sagging. Critically, do NOT overtighten the eccentric nuts. Make sure they are just tight enough to stop wobble, I had mine way too tight causing wheel wear. If you get layer shift, tighten belts more even if you think they are tight enough. CRITICAL: When hot, clean the nozzle of any filament before starting print. I had so many issues with filament gunking up the nozzle, then dropping off. I also HIGHLY recommend getting a CR Touch and using the Jyers UBL 15x15 firmware. Made my life so much easier for levelling. My settings right now: Extruder: 137.5 (for 100mm of filament) (with stock extruder tension). Retraction: 0.5mm and 25m/s speed. (I was originally trying 1.5mm and 2mm, which caused issues) Print speed: 30m/s with PETG. Hotend: 245 (up from 240), Bed 80c, then 70c after few layers I seem to occasionally get unexplained under-extrusion. Im still playing with settings though. The instructions were extremely thorough for this kit. I like the kit overall. Just -as mentioned- make sure you go around your printer and do the general maintenance to make sure everything is OK. I assumed mine was fine and spent a month with issues because parts were loose (wheels, eccentric nuts, belts).

Big improvement over stock (had oozing with PETG) and one of the first modifications I made to my Ender 3 Max. Retraction distances greatly reduced (~1.0mm now) and lower hotend temps (210 degrees now vs 235 before on PETG), along with faster print speeds and higher quality.

I installed this on my Creality Ender 3 v2. Installation was straight forward and well documented with photos. You have to download a PDF from the micro swiss site, as no paper instructions are included, but this wasnt an issue for me. It would have been nice if some of the hardware was included in the kit (bolts etc), but you can reuse some from your stock Creality hot end to get the job done. Unfortunately, this kit is not compatible with the ender 3 v2 fan assembly without printing a fan shroud. Not a huge deal, but still something I wish I had noticed prior to buying this kit. I dont know what they are thinking recommending the fan shroud to be printed in PLA, as mine (printed in petg) is getting decently hot. Maybe if you are only using the hot end to print low temperature materials, this would be fine. The extruder and the hot end are working really well. The direct drive gears fit perfectly, pulling the filament smoothly during printing and retractions. The hot end seems to be performing well without any appreciable heat creep towards the extruder (at least in the ~20 hrs of printing Ive done @245C). I did have to raise my printing temperature to get the same results using this all metal hot end, but that is something that is suggested in the instructions. The major issue I have with this is that the stainless steel nozzle that this comes with seems to stick really badly to petg compared to other nozzles I have used. Petg tends to be a pain as far as globbing up on nozzles of certain material, so I guess thats okay. I just wish it had come with maybe a spare nozzle of a different material at this price point. Some of the machined parts had a few deep scratches and gouges in them, which isnt pretty, but I dont think it will affect the performance of this assembly. I might end up getting a different hot end and extruder setup for my next printer, as there are a decent number of quality options around this price point. The ease of installation is definitely what made me decide to buy this, as its nearly a drop in replacement for the printers its compatible with. Overall, I do not regret this purchase at all, but I do think there is room for improvement in the parts included.

Worth the purchase

Quick install. Just change your esteps and replace gcode on slicer for start offsets. If your current extruder has the pressed in gear you will need a new motor with a flat on the shaft for the drive gear. I went with a pancake stepper to save weight. And decided to not use a Bowden tube.

Had to use my drill press and a thin wrench to press the old gear off my stock E motor, then ground a deep flat for the setscrew on the motor shaft, if you dont the grub screw for the motor gear will bind up the extruder. I had to trim my capricorn tube a mm shorter but otherwise easy upgrade. If you figure the price of great all metal hot end + good direct drive, you come out ahead (unless you use cheap knockoffs). I had to play with my E steps, 130 was too low, calibration put me closer to 145steps/mm, set retract to 1mm, some say 0.5-0.75mm I didnt have luck with that low.

Good quality and all but their quality control for missing parts is somewhat lacking, the box was missing the red filament guide.

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.
