Micro-Swiss All Metal Hotend Kit for Creality CR-10s PRO/CR-10 Max/Ender 3 V2 Neo

Finally able to print PETG with this on my CR-10S Pro V2. Amazing quality. Definitely a must for an upgrade to your printer for quality and versatility.

Not much to like here. The first kit was complete and got to the point of hot tightening the nozzle when the nozzle sheered off in the heat block with the torque driver set to 30 inch pounds as specified. Replacement kit, well I have no idea how the nozzle will fair since its missing the two screws that should be installed in the heater block to hold the heater in place. No way to tighten around the heater. Im going to dig through my tiny screw collection before returning it because I dont want the hassle but Im disappointed. Ive used Micro Swiss on printers in the past and they were great. Its too bad theyve gone so far downhill over the last few years.

I have the Creality CR-10s Pro v2. The stock hotend was failing. I know that Mirco Swiss are some of the best 3d printer upgrade parts out there so I purchased this. I had to do some re-calibration but after that this hotend prints much better than the stock hotend...IMO.

Love this hotend. Follow the directions for changing filament or you will have issue.

My hot end crapped out, so I figured “might as well upgrade”. The original price of this might seem kind of high, but it’s worth it. Super easy install with the manufacture provided video, everything is tidy in its own bag. Tools provided also, and first print ran with it was .01mm within spec at all places checked. I highly recommend this to anyone looking to replace their hot end.

This product is very well made and is a great replacement for the stock hotend. Extremely reliable hotend!

After using this Microswiss hot end on my CR10S Pro, and dealing with issues from my other printer running a V6, I feel that I now see the benefit of this design over the V6. The heatbreak on the MicroSwiss is much shorter and since the heatsink dips into the heatbreak it is even shorter still. I have never had heat creep with this hot end yet and I have run PLA, PETG and ABS. This short heatbreak seems to really help keep heat creep at bay, whereas the V6 with an all metal heattube which I also have, tends to require more attention to avoid clogs and it seems to require more force to extrude. I suspect the longer steel heatbreak on my V6 is holding and migrating the heat causing the melt area to extend higher up the tube, though I dont find it above where the heat sink starts. In any case I prefer the microswiss over the V6 now hands down. I have also had to contact their customer service on an issue and found they are excellent and get back quickly. As an aside, I think the ultimate direct drive would be a MicroSwiss heat tube + block mated to a compact extruder/hotend like the aero or hemera. Id buy one of those today if such a thing existed. 1.5yr update - the MicroSwiss is still going strong and its been almost problem free. Clogs are pretty well a thing of the past though they can still happen. When the filament gets stuck its usually because I didnt remove it correctly. The way I remove the filament is to heat the nozzle to about 20°C below the operating temp and then push it in a bit before pulling the filament out. If that doesnt work then I just heat it to operating temp and push it so some filament is extruded, then let it cool down about 20°C and then pull the filament out. No issues with clogs that way, and probably the best upgrade Ive done on my CR10S Pro (v1). Original Review: I have been running this hot end on my CR10S Pro for the past couple months, and have had no major issues with clogs due to heat creep. Installation went off without a hitch in about 10 minutes, just have to be careful not to strip out the grub screw holes in the aluminum heat sink, and tighten things when it is hot (this is the same for any hot end). I picked this up because I wanted to print with higher temps and did not like having PTFE in the hot end when running above 240C. I dont notice any significant difference in print quality, but it has been reliable and looks well machined. I suspect that the nozzles are better quality though, and would probably buy their plated nozzles in the future. The docs I have seen for this hot end specify that retraction should be kept under 4mm, however I have been running it at 5.2mm @ 45mm/s without any issues. I tried 4mm but there was too much fine stringing, so I feel that is too conservative and actually would force me to find something else if it really could not go higher than 4mm.

I have never had so much confidence in my CR10 MAX until I put this on. Biggest difference other than quality is that you can use normal threaded nozzles! Great product. I’m never scared to print even really large things.

Works great. I can print at much higher temperatures now! Just needed a bit of tweaking to the retraction settings when printing.

Installed by a friend who has way more experience doing this sort of thing. He said it was easy and it worked well.
