Chain instead of belt

[moop]

I am doing a core xy with a voron2.4 style gantry and I was wondering about swapping the belts for a chain. Less stretch? Less deformation over time? Can handle high acceleration and more force?

Be sure to take into consideration the mass change if you move from a belt to a chain. The weight of the belt is going to be far less than a metal chain. The weight of the chain is going to reduce the acceleration you'll have available.
