Project Escher Meant to Speed Up 3D Printing

[curious aardvark]

logical progression. Don't see why it should be so difficult.
It's all down to the slicer :-)

But clever and a good idea :-)

And with something like a rep clone. You could extend the printing width to the potential maximum of both heads. As the left head could print max width left and the right max width to the right.
Think I worked out once that it would give you another 3-4 inches length. So take it out to around the 300mm mark.
