Got this hotend to print filled material and it seems to be OK, but the markings on it make my H2D read it as a hardened nozzle, NOT a Tungsten one. Tried 3x to read it, same result. Again, the nozzle APPEARS to be made of a non-steel material. Is it Tungsten? No way to know, but be aware that if your printer reads it like mine does, you may have to go in and manually define it as a TC nozzle instead of what it might read as. Currently have a wood PLA (Elegoo) job running with it, we'll see how it comes out.Whether the misreading will impact any internal settings on the printer (printing as if it was hardened instead) remains to be seen, but it's not "install and start printing" at this point. Unknown how it will wear compared to a hardened nozzle, I guess time will tell.

Extra hotends for my Bambu printer are something that I like to keep around as much as possible. Having one that's a Ruby Nozzle is also nice. Mine fit fine and seems to work well. Since I haven't used it a tremendous amount I can't attest to the durability at this point. But I would hope that it will be fine in the long term.

Imprime y se coloca bien, lo único es que la funda de silicone no entra bien y da error en la p2s, para poder imprimir y que no de el error tuve que colocar la funda original que tenia mi boquilla de 0.4 y calzo bien en la 0.6 y asi quito el error que salía el la pantalla, de resto todo bien

If printing any composite materials THIS is your guy.The layer lines on PA6GF25 has no layer lines.Looking for .4mm nozzle though.

This replacement nozzle was truly a drop-in replacement for us on our h2d and was directly compatible with both fit and position. Even though it features the signaling pattern on the front, I personally wasn't able to get the nozzle detection feature to work (probably because I used the right side), but new firmware updates allow you to specify both the nozzle type and independently from the other side, meaning I was able to get it working in the slider no issue. Our plan is to use the extra hardened end for abrasive filament with bigger layer height for super strong usable parts. Some tests prints with ABS at 0.4 height went by without any issue, and sped up the process. I can recommend it as an alternative to the original.
