Dual Wire Gantry ?

I'm interested in the Dual Wire gantry shown :-

There would need to be simple modifications so the belt isn't twisted other than that it seems good.

Simply does it work and is it any good? The printer would have a 200x200mm build plate.

There is one stepper at the back.

I think I have worked out the problem there are a lot of wheels, direction changes and the belt is long.

I don't think it's in that respect its worse than CoreXY motion but it's only moving the printhead.

I don't think you're going to get XY positioning with a single motor.

No the Y motion is not done with those belts, you still need a conventional set of Y axis rods and belts to move the printhead +- in Y.

The problem is that the diagram is minimal at best, I have tried to link to the wiki page but with out much success. I'll try again

better diagram and discussion
