Model Breakdown: Key Strengths, Use Cases & Material Compatibility

1. NBS-6040

Footprint & Setup:

  • Footprint: approximately 0.73 m² (950 × 765 mm)
  • Most of the assembly is pre-configured; only basic structural setup is needed, usually under 30 minutes.

Key Advantages:

  • All-aluminum frame is compact and rigid
  • Easy to operate and maintain
  • 710W spindle with ER11 collet
  • GRBL 1.1f control system for beginner-friendly operation

Best For:

  • DIY projects
  • CNC learning
  • Makerspaces
  • Small creative product manufacturing

Recommended Materials:

  • Softwood
  • Acrylic
  • PCB boards
  • Soft metals
  • MDF

2. NBS-6050 PRO

Footprint & Setup:

  • Footprint: approximately 0.90 m² (1016 × 881 mm)
  • Pre-assembled components; basic setup typically ~30 minutes.

Key Advantages:

  • Larger work area than the 6040
  • NEMA24 closed-loop stepper motors
  • Inductive limit switches for improved stability
  • 710W spindle with ER11 collet and real-time speed display
  • Excellent balance between value and performance

Workspace Planning Tip

For optimal operation and maintenance, we recommend planning for approximately 1 meter (3.3 feet) of lateral clearance around the machine. This provides enough room for maintenance, tooling, and accessory access.

Software Compatibility

All four NBS machines use GRBL firmware and are compatible with a wide range of CNC software platforms.

When Should You Upgrade Your CNC Router?

You don't need to upgrade just for the sake of owning a larger machine. However, if your workflow is facing any of the following limitations, it may be time to move up the NBS product line.

1. Work Size Expansion

  • Larger one-piece projects
  • Reducing split-and-join operations
  • Designs exceeding your current work area

2. Material Expansion

  • Transitioning from softwood to hardwood
  • Machining aluminum, brass, or metals
  • Need for higher rigidity and torque

3. Workflow Expansion

  • Multi-step machining
  • Continuous production
  • Batch manufacturing
  • Commercial delivery-focused workflows

Final Thoughts

The NBS series is not simply a lineup of different machine sizes — it is a complete CNC ecosystem designed around different stages of use.

From beginner learning to advanced commercial production, each model serves a clear and purposeful role.

Ask yourself:
  • What materials will you cut?
  • How large are your projects?
  • How may your workflow evolve in the future?
Once these answers become clear, choosing the right NBS machine becomes much easier.
