💡 What makes ball screw-driven CNC kits better?
Ball screw systems offer higher precision and repeatability than belt-driven systems:

1. Reduce backlash with tight mechanical efficiency

2. Support heavier loads without sacrificing accuracy

3. Provide smoother, quieter operation under continuous use

This kit gives you the foundation for a powerful, DIY CNC router ready to handle demanding applications. Add your own motors and controller to get machining in no time!
