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

I recommend look a better options. This has been a waste of money and time. I continue to get a pool of PLA near the metal break. The grub screw does not do a good enough job holding things tightly in place. There should be more than one silicone cap included because it seems to tear around the edges. One of bolts that secure the thermal probe in place have stripped on me already and there is not an included replacement on that either. Also, the Thermister does not have anything that holds it securely in place. This is really not a major upgrade from the e3v2 hotend and I regret purchasing it. (Less than a month)

I bought this hotend for my CR10-s Pro printer after the heater cartridge shorted out and I couldnt remove the original heater cartridge for replacement. This product is direct swap and the instructions are easy to follow. I do say when you install it, make sure you install the nozzle into the block until finger tight and then back out about 1/4 of a turn. install the metal tube until it sits flush with the nozzle. Once that is installed and your thermistor and heater cartridge is installed. You can then heat the hotend up to 230c and then carefull using a pair of pliers and a appropriate socket tighen the nozzle into place to ensure of a proper fitting. once I did that I adjusted some retraction settings in my slicer and i print about 5 degrees hotter than the stock hotend and It prints like a dream. I dont think i will have any issues printing any exotic matrials like PETG. TPU or flexibles with the new hot end. I highly recommend this hotend if you want to get more bang for your buck on your CR10s pro printer.

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.

Ive purchased three of these for my Creality printers, I bought the latest one August 9th 2019. Three major flaws in the latest one. 1. The Bowden tube can slide out randomly, within the first minute or two of printing. 2. The set screw does not keep the heating block from rotating. 3. Filament is extruded through the thermistor hole. A minor fourth complaint would be the heat break ID was really tight on all the filament I tried to run through it cold. Ive seen this with other heat breaks and have a drill bit that cleans up whatever is left over from machining. So this wasnt as bad a problem as the three above. I love my other Micro Swiss all-metals but am leery of buying any more if their manufacturing quality is lower than the first few I purchased.

Its a fantastic hotend and contrary to popular belief it wont cause problems when printing PLA, not if you get a good quality all metal one like this Micro Swiss. Super easy to install and the harden nozzle opens way more filament options not to mention youre no longer limited by the temp of your PTFE tube. I cant recommend this if you just print exclusively in PLA but if you want to tackle other high temp filaments, this upgrade is a no brainer. Remember to reduce your retraction to no more than 4mm and make sure you run the fan at all layers when printing with PLA and you wont run into any issues.

Fitted to my CR-10S Pro and is better than the original equipment in my view. The heat break design in particular makes changing anything in the heating block much simpler. The nozzle that comes with it is great but coupled with a Micro Swiss MK8 Plated M2 Hardened High Speed Steel Nozzle this just cant be beat. If I get another CR-10S Pro then I will be changing out the hotend for this before I even print anything. Its that good.

Works perfect I’ll pricey but you won’t have to buy it again

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

Everything about this was great, no clogs or anything bad happening, but after going to clean the nozzle and hot end and trying to put them back on, the set screw holding everything in place and the threads for said screw just ripped and failed. Now Ive waisted sixty dollars and a 600 dollar printer out of commission. I thought these things were good but theyre just complete crap. Dont buy this.

Was having issues with backflow from previous hot ends. I have not had that issue and have printed many long prints with much better surfaces. Would reccomend highly.
