Looks OK to me. But given that you only need to raise the non-printing nozzle about 1mm higher than the printing one, I think you could use a much simpler arrangement, base on tilting or rotating the entire print head by a few degrees.

Yes David, that's true. But that does not solve issues that this design or the IDEX design solves, like stopping oozing, keeping the hotend at the working temperature all the time, keeping pressure inside the melting zone, wiping the nozzle before using it. It has the advantage over an IDEX solution that it's compact, no extra carriage and motor needed, simpler to configure.

Hmm... That's not quite true. Tilting mechanisms can just implement small blades that cover the inactive nozzle to stop oozing. Or set firmware to have a standby temperature. Or both!
I do however like the idea that it is raising the nozzle at the same time, where as tilting mechanisms have a chance of flicking the print as it moves. Could your mechanism move quick enough to stop all oozing? Tilting a nozzle a few degrees is very fast.

It's a variation of the tilting extruder some users experimented with, but I never saw this particular system implemented anywhere."

I'm just gonna do a little shameless self promotion:

I would love if some people would implement it on their printers. It's worked super well so far.
