How GT2 Pulley and Timing Belt Work
The GT2 system uses synchronous timing belt technology for precise motion control:
- The pulley rotates with the motor shaft, driven by your stepper motor
- The belt teeth engage with pulley grooves, creating a positive drive connection
- Motion is transferred without slipping, ensuring precise positioning and repeatability
A 20-tooth pulley provides a good balance between:
- Speed: Higher teeth count means more movement per rotation
- Precision: Optimal teeth count for fine control and accuracy
Applications of GT2 Pulley and Belt System
- 3D printers for X and Y axis motion systems
- CNC machines and routers for precision cutting
- Laser engraving machines for accurate positioning
- DIY robotics and automation projects
- Plotters and camera sliders for smooth movement
- Belt-driven linear actuators and positioning systems
