I guess you have to have them somewhere, at least for the fixed spans so they might as well go inside the mechanism. I was referring to the long internal beams that pass through the whole assembly.

Are you referring to the thin internal members on the hinge assembly or the long and straight pieces inside the larger assembly that cover the belts? The thin internal members on the hinge-pieces are for stiffening and strength and are thin (rather than each hinge piece being a flat panel) to reduce print times and materials cost without sacrificing strength. The long, straight modular pieces inside of the assembly (actually called "spines") are an attempt at reinforcement against compression of the whole assembly and torsion. There is a little question as to how necessary they are. One earlier assembly actually did away with the spine on a non-motorized section, and there's been talk of trying out the whole X-Y table without them. The spines?

Do they carry any weight from the carriage? I recently bought parts for a Mendel. I spent $50 on steel rods and $50 on bearings. If this thing is smooth, accurate and fast it could really cut down on cost. What is the purpose of the spines on these linkages? Do they carry any weight from the carriage?

One issue is the notion that 100mm^2 parts are makerbot printable. Anyone accomplished this? At least with ABS it's really warping. Plus the machine might need tweeking to make sure it doesn't hit it's limits on ever turn. awesome stuff. One issue is the notion that 100mm^2 parts are makerbot printable. Anyone accomplished this?

They're the size of a cockroach and the chassis, members and linkages are stiff folded paper.

As neat as a still of this looks, in motion I bet it looks awsome! Think you can put up a video of this in action? As neat as a still of this looks, in motion I bet it looks awsome!
