I received a J-Head MK-V with a 0.35mm orifice, which will (hopefully) replace my old MK-III B.
The new MK-V is a bit shorter, got grooves milled into the PEEK to allow heat to get out easier and away from the PTFE liner inside.
I got high hopes for this, and the MK-V can thank it’s older brother for this.
As you see, this looks very used with the leaking, dirty kapton tape, and still a bit of pla sticking out of the orifice.
It still performs great, and the print quality is still the same as when I first got it. It is the hotend that has printed the most hours by far without problems, it survived a firmware bug where the heat was not turned off when it should have been. And it also survived my newbie days with colissions with the bed and so on.
