it became a nice alternative to stencils and ovens
I'm slightly curious about that. If you're already sending your board out to get fabbed, you can get a stencil done at the same time. They cost about a tenner for as many stencils as you can fit on an A4 sheet of transparent film. If you don't need very fine pitch (I did 0.5mm pitch LGA-16 packages no problem), then you can do one at home on a vinyl cutter.
It did take me a while to get the hang of using a stencil though I must say.
Agreed that these days if you have some way to reflow, then getting a stencil at the same time as the board is painless. I'm still getting the hang of applying the paste, so having the machine do it seems a good alternative as it will likely do a more precise job of it. But I won't know until I get a unit of my own.
As I said before, in light of the OtherMill and DIY reflow oven, it's no longer clear what niche the Voltera will fill in my workshop. At the very least it will be cool to have been part of early development of this type of prototyping, which seems like it has the potential to get a lot better with more R&D. Even if I end up selling it or donating to a worthy cause like a school or Maker Space, I don't think I'll have any regrets.
