Micro Swiss MK8 Plated A2 Tool Steel Wear Resistant Nozzle (MakerBot, CraftBot, Creality, CR10, Ender 3, Ender 5, Tevo Tornado) .4mm

I received an used nozzle, it has filament remanents on it. Not sure how this can happen.

I original got this nozzle for my ender 3. The nozzle works well, material doesnt clump up on nozzle as much and it handles abrasive filaments well. One thing I had to do was turn up the temperature for PLA filament by about 10°C to get the plastic to flow consistently.

It is a quality nozzle. I havent run anything abrasive through it to know if it would last longer then a none hardened nozzle. The 8mm tip is great for prints that dont have a bunch of small details, cuts the time to print in half.

Maybe there was a quality control issue with the one I had ordered but mine came significantly longer (almost half a cm) than my other nozzles of the same design and what should have been the same form factor. I wound up having to measure out a piece of filament, gently melt the tip and attach it to my bl touch so the probe would extend past the tip of the nozzle. Once that was taken care of this prints beautifully. Just a major hassle whenever I want to switch nozzles.. Between needing to fiddle with the bit of filament and drastically altering the z offset.. switching to this nozzle takes me an extra 10 minutes or so to get everything keyed in. Switching back takes less time, especially if you take note of the settings you were using before switching to this. Hopefully I can figure out something to clip onto the probe so I can just have a known value for this in my notes. You can get pretty close since the piece of filament is measured, but it changes when you melt the tip and stick it to the probe and might not be totally vertical creating more of a varience. Fiddly and frustrating.

I have a couple of spools of Luminescent Blue filament and a spool and a half of Carbon Fiber. Im told these filaments can wear out a brass nozzle in a single print so I needed something more durable. Tungsten nozzles were out of stock for a while, and the hardened steel nozzles were rated almost as tough, so I ordered and installed this on my Ender 3 Pro. I read online the process for swapping out a nozzle and gave it a go. No leaks, and prints come out fine.

Seems legit a file won’t cut it!

I see y every one seems to like them

I almost exclusive print with carbon fiber polycarbonate and this nozzle has now ran through two full spools and hundreds of amazing prints the only thing I wish they would do is add a non stick coating to the outside.

I have only had this nozzle for about a month and so far it is doing really good. Im using it on my Ender 3 with the Micro Swiss All-metal hotend. I havent notice any extrusion issues so far with it. All my prints have come out nicely with it. Only thing I did notice is I had to increase my print temps about 5-10 degrees. Not sure if thats because this nozzle or the entire hotend. So far I would recommend this nozzle. Will probably be buying some more in the future as long as it lasts for a while.

For the price of these nozzles, I expected much, much better performance. The plating is supposed to reduce filament sticking to the nozzle outer surface. Not seeing that at all. In fact just cleaning it off with a brass brush after one print job, the plating came right off and exposed the brass nozzle body underneath. Not impressed. Super expensive and prints no better than my plain jane inexpensive brass nozzles. Wont but this again. NOTE: I Love their All Metal Hotend and Direct Drive mods, but not a fan of their over priced nozzles.
