💡 What is a timing pulley used for in 3D printers and small CNC setups?

It’s a handy, precise drive component that converts motor rotation into linear motion while keeping belts aligned.

- Keeps belt timing and tension under load
- Enables reliable motion in tight spaces
- Simple upgrade path for HTD3M belt systems
- Works with standard 6mm bore shafts in hobby machines
