- Tool Storage: Keep end mills, collets, clamps, and maintenance tools organized and nearby.
- Safe Practices: Use safety glasses, ear protection, and follow proper safety protocols.
4. Select CNC Software
You’ll use three main types of software:
- CAD (Computer-Aided Design): For drawing your project (e.g., Fusion 360, SketchUp, VCarve).
- CAM (Computer-Aided Manufacturing): Converts your design into toolpaths (e.g., Carbide Create, Aspire).
- CNC Control Software: Sends code to your machine (e.g., Mach3, GRBL, Universal Gcode Sender).
Many affordable machines come with beginner-friendly software bundles.
5. Learn the Workflow
A typical CNC project follows these steps:
- Design: Create your part in CAD.
- Toolpathing: In CAM software, define how the tool moves.
- Post Processing: Generate G-code (machine-readable instructions).
- Setup: Secure material, install tool, set zero points on the machine.
- Run Job: Start the machine and monitor the process.
- Finishing: Remove the part, do any sanding, cleaning, or assembly.
Key Benefits of a Home Shop CNC
- Time Efficiency: Quickly produce multiples of the same part.
- Expanded Creativity: Experiment with shapes/patterns not achievable by hand.
