Micro-Swiss Duese MK8, 0.4 mm M2585-04

I don’t understand how people are having problems with this nozzle. I will say that 99% of negative reviews on here are due to user error. I installed on stock Ender 3 hotend to print Carbon Fiber PLA. Installed the nozzle correctly, upped the temp in Cura about 5c (print a temp test tower to find your temp) and started printing. Been through at least 4kg of CF/PLA and 8kg+ of PLA and PETG without any clogs or other problems.The nozzle still looks great, stays clean, and prints beautifully.

Works great on the Monoprice Ultimate 2So first of... many review complaints state they have to increase the temperture settings to get good print... and that their old temperature settings worked great with cheap brass nozzles so why don't they work with this expensive nozzle... then they give this nozzle a bad rating.It PHYSICS! Brass conducts heat much faster than steel. The temperature sensor is in the heating block, not the tip. So the system doesn't know you changed to steel tip that does not conduct heat as fast as brass. As a result you will need to run tests with your favorite filaments to figure out what the best temperature setting is for the steel nozzle.Once you take the time to figure out the new temperture, it works great and last A LOT longer than the cheap brass nozzles.It's your choice, take the time to figure out settings for a nozzle that will last a long time, or keep buying cheap brass nozzles and throwing them away.

I got it to work, and it work with about a half dozen prints. The fastest I could get the nozzle to work was 20mm/s at 260C using PETG, and the same speed at 240C using PLA. Up until this point I was using the cheap brass ones from china (the kind you can buy in a 30 pack for $10). They printed at 230C and 60mm/s for PETG, but needed to be replaced monthly. I desperately wanted this nozzle to be my forever nozzle. The one that I would put in and never need to replace again.Sadly this is not the case. I gave it 2 stars because it does work, it's just energy and time inefficient. And after 2 saturdays of playing around with this, I'm done. I'm going back to the cheap ones and I'll try to recycle them so I don't feel so bad about the waste.

The quality of the nozzle and the quality of print is at the top. I am giving it 3 stars because this nozzle cannot print effectively unless at very slow speeds. I can only run at 20mm/s with it vs the brass nozzle it replaced. I was running 50mm/s on the original nozzle that came with printer. Going over 20mm/s will cause the extruder to eat through the filament because the nozzle cannot heat the plastic fast enough.. I can bump the speed to 25mm/s if I bump the temp to something like 20 degrees above the recommended for the filament but I am uncomfortable with that so I will not be using that as a way around this.Taking the nozzle off and inspecting it shows there are no clogs. Inspection also included that of the Heater block, break and heatsink. Extruder is clean with no visible signs of clogging or wear.

Tried this nozzle on the Creality Ender-5 with the Micro-Swiss All Metal Hotend. The hot-end printed the parts, but this nozzle caused tiny hairs to be pulled across the part when the hot-end moved. Adjusted all sorts of retraction settings, but couldn't get past the tiny hairs. This wasn't too big of an issue as I could hit it with a hot air gun that I use with heat shrink and clean them off.The real problem came in with bed adhesion. Using this nozzle, the PLA+ would not adhere to the bed through the entire print and caused warning. I replaced it back to the standard nozzle, using the same gcode, same temperatures, same material, same bed surface and my PLA+ had no issues with adhering to the bed.In the pictures, the part on the left is printed with the standard nozzle and the part on the right is the Micro Swiss MK8 Plated A2 Tool Steel Wear Resistant Nozzle. Same gcode used for both prints. You can see the adhesion problem with this nozzle and PLA+Whatever they used to coat this nozzle for wear resistance, drastically affects the materials.
