Verdict: Best for advanced users and developers who want complete control over their CNC system and are comfortable with Linux.
5. Inkscape with Gcodetools
Inkscape is a free, open-source vector graphics editor, and with the Gcodetools extension, it can be used to generate G-code for CNC machines. While not a dedicated CAM software, it provides a basic workflow for creating and cutting simple plasma designs. I’ve used it for quick projects where I didn’t want to fire up a full-fledged CAM program.
Pros:
- ✅ Free and open-source
- ✅ Easy to create 2D designs
- ✅ Simple G-code generation
Cons:
- ❌ Limited CAM capabilities
- ❌ Gcodetools can be finicky
- ❌ Not suitable for complex projects
Verdict: Good for beginners and hobbyists who need a free and simple solution for basic plasma cutting projects.

- Your Budget: Software ranges from free (open-source) to subscription-based. Consider the long-term costs.
- Project Complexity: Are you cutting simple shapes or intricate designs? Complex projects require more advanced features.
- CAD Integration: Do you need integrated CAD capabilities, or are you happy using separate CAD software?
- Machine Compatibility: Make sure the software is compatible with your CNC plasma cutter and controller.
- Community Support: A large user community can be invaluable for troubleshooting and finding tutorials.
- Operating System: Ensure the software runs on your computer’s operating system (Windows, Linux, macOS).
Before committing to a purchase, try out free trials or open-source options to see what works best for you. Also, check online forums and communities for user reviews and recommendations.
FAQs
Q: What is CAD/CAM software?
A: CAD (Computer-Aided Design) software is used to create designs, while CAM (Computer-Aided Manufacturing) software is used to generate toolpaths for manufacturing those designs on CNC machines.
Q: Do I need both CAD and CAM software for plasma cutting?
A: Yes, you need both. CAD software to create the design and CAM software to generate the G-code that controls the plasma cutter.
Q: Can I use free software for professional plasma cutting?
A: Yes, you can. LinuxCNC is a powerful, free, open-source option. Inkscape with Gcodetools can work for simpler projects, but it has limitations.
Q: What is G-code?
A: G-code is a programming language that tells CNC machines how to move and operate. It’s the language that the CAM software generates and the CNC controller interprets.
Q: How important is customer support for CNC plasma software?
A: It can be very important, especially for beginners. Good customer support can help you troubleshoot issues and get the most out of your software.
Conclusion
Choosing the best CNC plasma software depends entirely on your specific needs and experience level. Fusion 360 is a powerhouse for professionals, while SheetCam offers an accessible entry point for hobbyists. Mach3 and LinuxCNC cater to experienced users seeking customization, and Inkscape with Gcodetools provides a free option for basic projects. Take the time to evaluate your needs, try out different options, and choose the software that empowers you to bring your metalworking visions to life.
