Neptune 4 Max belt's gone slack or torn, and your Y-axis is drifting. This is the correct replacement timing belt, part TL4976. Works with both ribbon-cable and Type-C cable versions — just confirm which one you've got. Swap it in, seat the tension, and your print's back on track. No hunting for a generic belt that might not fit
