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

This is a great drop in replacement. No problems so far with it.

First of all, this is my third printer Ive installed this on. I was wanting to print some high temps, and wanted the freedom of the nozzle size, since I have lots of extra nozzles. I was able to get this installed in about 30 minutes. Ever since, its been working flawlessly and Ive been getting much better prints off it.

Followed the instructions outlined in their youtube video -- the bowden tube is not as easy to remove as instructed, and actually requires the block to be heated up in order to remove it. These instructions seem to be geared towards a brand new printer rather than an upgrade piece for a printer in use. When tightening the hot-end to the slotted block, the nozzle snapped in half. The hot-end piece inside the wrench and the threaded part still inside the block and now impossible to remove making the entire assembly a useless waste of $65. This was after assembling the entire block, preheating the hot-end to 230 and attempting to tighten for seal as per the instructions. When disassembling the block to put the stock one back on, the tiny screws at the bottom of the block holding the heating element in place stripped while using the tools provided in the kit. This made the entire printer useless, as neither the snapped hot-end can be removed, nor the original block re-installed. This tiny piece of cheap metal bricked a $700 printer, beware.

The real deal. Works great. One of my favorite upgrades on my CR10 MAX. Has no problem printing at .6 layers

Amazing product! Last hotend you’ll ever need

Nice extruder needs so modifications to design to keep the grub screw from stripping. Need to tap the right or left side for a longer grub screw the same size to give more threads to bite on too, if you remove the grub screw a few time like 10 over the years the threads get wreckt. Also a longer grub screw to fully take advantage of the very small amount of threads would have also helped the problem, poor engineering. Excellent quality overall. Wouldnt suggest the price point till they redesign the extruder. That is the only problem Ive ever had with it.

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.

Installation was easy enough but after that it was nothing but problems. I was unable calibrate my feeder e steps consistently for reasons unknown even though I did a PID auto tune. After I got the feeder e steps somewhat consistent, stringing tests were a complete mess and I tried to tighten everything while the hot end was heated and stripped the heat block. My ender 3 stock hot end worked perfectly fine and I heard so many good things about micro swiss hot ends, DO NOT BUY THIS IT IS MORE TROUBLE THAN IT IS WORTH.

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

Love mine and wish I would have bought these years ago.
