Space Maker CNC

Space Maker CNC is a project to create and document the creation of a CNC usable for creating space grade components.

The goals for the project are:

• Minimum 0.1mm finished product accuracy
• Capable of milling aerospace grade aluminium (Al 7075)
• A work space of 500*500*300
• Total cost of BOM under 2,000 USD

---

Progress

• Base structure (complete)
• Base linear rails (complete)

Next steps

• X-axis ballscrew
• X-axis motor
• Gantry structure
