wow thank you very much, I was kind of wondering about a lot of things you just said.
ok I'll shut up now. Going back to the drawing board and rethinking everything.
Maybe I'll just clean up my mess and be happy with my 2 single extruder printers.

I actually am pretty happy with both, I was just looking for a new project and had always wondered about dual extruders. I think I'm off of dual extruders now but I might start thinking about a 2 into 1 for the delta.

The printer on Thingiverse is a bit much for me. I can put together a kit no problem, but I don't think I want to dedicate that kind of time and energy for gathering everything on my own. Not yet anyway.

And I do ok but there is no way I would spend 8 grand on a printer. This is just a hobby of mine.

Thank you so much for all your time and energy and insights. You probably saved me a bunch of money and frustration.
