Large Delta printer build - advice and suggestions welcome

Finally, that's not how elasticity works. The belts and springs are elastic and can stretch no matter how many motors you put on them. You know what? Fine, I'm an idiot, you must be a professional mechanical and mechatronics engineer, doing things no professional machine would, like using two motors on one closed loop of belt. Let us not forget your breakthrough in belt technology: the belt you can push on!

I know it is hard to see the big picture when all you got is a small screen so to better explain my loose definition of function, on most printers when the bed or extruder goes in one direction the belt is pulled on the short side. that is there is a very short distance between the motor and what it is pulling, but when we move in the other direction we are now pulling against the tensioner spring, the idler, and a whole lot of length of belt. With a stepper motor at each end we are always pulling from the shorter side of the belt and with no idler or spring or anything in between. My reference to push and pull is to point out that the steppers are both moving in both directions so there is always 2x more torque applied. Now go see if you can make your honda run on PLA.
