If you have ever tried to manufacture a printed circuit board at home using a CNC router (such as a 3018 or Genmitsu), you quickly realize that your Gerber files are useless to a milling machine. You need a middleman: CAM software.
For the hobbyist and small-scale professional, two names dominate the conversation: CopperCAM (developed by Gilles at LPKF) and FlatCAM (developed by Carsten Presser). Both claim to do the same job: convert Gerber/Excellon files into G-code. However, they go about it in radically different ways.
Choosing the wrong software can lead to broken bits, short circuits, or hours of wasted time. In this deep dive, we will compare features, user interface, algorithm quality, cost, and workflow to help you decide which king of the engraver hill deserves a spot on your hard drive. Coppercam Vs Flatcam
Many professional makers use a hybrid workflow:
Ultimately, for the CNC hobbyist with a generic 3018 router running GRBL, FlatCAM is the recommended choice. It is free, it is mathematically sound, and it won't plunge your bit into your $50 PCB material. CopperCAM remains a legacy tool for LPKF users and those who value a quick, dirty, visual workflow over mathematical perfection. If you have ever tried to manufacture a
