E3D tool-changer - this machine looks amazing, though I’m disappointed E3D are not going to build a fully-functional version. I get what Sanjay is saying, that this is a “reference build”, but I can’t help feeling they’re missing an opportunity. Plus, E3D are 7 miles from my house, so it’d be cool to have local support 
I think they got a little burned by BigBox and decided their efficiencies are supporting other builders rather than competing with them.
@John-Paul_Hopman they certainly seem to be doing well in that respect, their hot-ends seem to be fitted to a huge range of machines. As I said, I just like the idea of a major machine manufacturer on my doorstep…
