Buying Guide

What should you check when buying a second-hand CNC router?

• Working area and footprint: Ensure the machine fits your workspace and supports your typical project size.
• Spindle and power: Verify the spindle’s condition, RPM range, and motor stability. Look for signs of overheating or irregular sounds.
• Frame and build quality: All-metal frames generally offer greater rigidity and precision over time; check for wobble or looseness in axes.
• Control system and software: Compatibility with GRBL, Mach3/4, or other controllers matters for ease of use and updates.
• Ease of parts and upgrades: A strong community and readily available spare parts help with long-term maintenance.

What are practical upgrade paths?

• Upgrade spindle or power supply to increase cutting capability.
• Replace the Z-axis with a higher-precision option for finer engraving.
• Enhance dust collection and enclosure to improve cleanliness and safety.
