Hardened steel nozzle and abrasive filaments
I was looking at this interview that Thomas Sanladerer did with Josef Prusa about the Prusa Mini. At 12:15 in the video they talk about the hotend. Am I understanding it correctly that it should be possible to mount a hardened steel nozzle to it and print abrasive materials? I have got a hardened steel Micro Swiss E3D V5-V6 compatible nozzle that I am thinking of using.

I'm using a 0.25 Nozzle X without problems.
RE: Hardened steel nozzle and abrasive filaments
Same here, 0.25mm Nozzle X without issues.
RE: Hardened steel nozzle and abrasive filaments
I was just about to search for Nozzle X compatibility, Glad I can use it with the Mini

RE: Hardened steel nozzle and abrasive filaments
Just keep in mind that the Nozzle-X is essentially just a hardened steel nozzle with a coating and rated to higher than normal temps. It doesn't have the same thermal characteristics as brass. Great if you're printing at high temps (higher than you can on a Mini). If not, there are cheaper alternatives. Don't own a Mini myself yet, but I'd try P3-D's Apollo coated nozzles for non-abrasives, or Hercules for abrasives.

RE: Hardened steel nozzle and abrasive filaments
Please be aware that there are many abrasive filaments,
those without particles incorporated in the filament (Say Glow in the Dark filament) will work with a 0.25mm nozzle...
BUT those like Carbon Fibre re enforced filament, will clog in small nozzles...
some folk have problems with carbon fibre filament in 0.4mm nozzles... I got hardened 0.6mm nozzles for Carbon Fibre!
Typically hardened nozzles need slightly raised temperatures, compared to the same filament with Brass nozzles.
I don't plan to switch between hardened and brass on a regular basis, unless I am also changing nozzle size.

Good Advice, I wasnt aware of this.. I will make sure I have different nozzles depending on what I intend on printing with.
I want to print with a mixture of filaments, I take it if you use something like a Palette 2 and mix filament types its better to go with the bigger nozzle to be on the safe side
