💡 What is a GT2 timing pulley used for in a 3D printer belt drive?

In simple terms, it converts motor rotation into precise linear motion along the axis.

- It works with GT2 belts (2 mm pitch) for reliable axis movement - The 6.35 mm bore with 2 screws secures to the motor shaft - The 30-tooth design yields consistent belt travel per revolution - The 6 mm wide groove keeps the belt seated under load
