I'm building an automatic litter box for my kitty and I tried building two versions using a GT2 timing belt + pulley but the belt seems to slip from the pulley often (since it requires high torque) and once the belt snapped.
Do you have any recommendations for a higher torque timing belt and a corresponding pulley + tensioner I could buy? I am currently looking into a timing belt for a car + a tensioner + pulley, but perhaps that's overkill. It is pretty cheap though.
More generally, I am also open to suggestions to linear movement without a timing belt, but I'd like the solution to be relatively cheap (under $100 for 2ft of movement)
