Thanks for the link, that does look intriguing.
But wow I am surprised at what you said about dual extruders in general, not as useful as I think.
idex - I did not know that term, thank you, I think that is exactly what I want.
haha well that is what I thought I wanted before I read your post. haha Now I am thinking about it again. But I do like the printer in the link, thank you for that.
For a while I was working on a dual extruder effector for my Anycubic linear plus, but then I had second thoughts. I ditched the Trigorilla board and I went with an MKS board running smoothiware about a year ago. I love it, the printer prints great now, no more delta dome. But I think adding dual extruders to a delta is asking for trouble (even with Smoothiware) so that why I am thinking about a 3rd printer now.
