Does not have built-in real-time probing or autoleveling. It expects you to use a hardware depth controller (like a floating head) or handle the autoleveling directly inside your CNC control software (like Mach3, LinuxCNC, or bCNC).
CopperCAM is a popular PCB design software that offers a range of features for designing and manufacturing PCBs. Developed by Thomas Madsen, CopperCAM is a free, open-source software that supports various file formats, including Gerber, Excellon, and ODB++. The software is designed to work on Windows, macOS, and Linux operating systems.
In the world of DIY PCB fabrication—specifically for those using CNC routers to mill their boards—the software used to convert Gerber files into G-code is the most critical link in the chain. Two names consistently dominate the conversation: and FlatCAM .
: Since it is a paid product, it tends to be more polished and stable for standard Windows environments. FlatCAM: The Open-Source Powerhouse
: It can handle more than just G-code generation; it's frequently used for complex geometry operations, Gerber to DXF conversion, and specialized copper pour cleaning. Coppercam Vs Flatcam
Understanding the foundational differences between these two programs explains why their user experiences differ so drastically.
Because raw PCB blanks are rarely perfectly flat, autoleveling (mapping the height of the board using a probe before milling) is vital for isolation routing.
Very low. The software features dedicated toolbar buttons for sequential steps: loading Gerbers, calculating isolation paths, hatching clearance areas, and exporting G-code.
You can write Python scripts to automate repetitive tasks. Does not have built-in real-time probing or autoleveling
When milling high-frequency circuits or boards that need massive isolation distances, you must clear large areas of copper.
CopperCam is a commercial, wizard-driven program designed specifically for PCB milling. Its interface feels like a traditional Windows utility. It relies heavily on top-down menus and automated dialog boxes. When you import Gerber layers, CopperCam actively attempts to recognize, order, and align them automatically. The workflow is largely linear: import, define tools, calculate isolation, and export. FlatCAM: Object-Oriented Precision

If you tell me (e.g., Nomad, DIY, 3018) and whether you're on Windows or Mac/Linux , I can help you decide which software fits your setup better. Developed by Thomas Madsen, CopperCAM is a free,
Sarah, meanwhile, hit the "Generate Geometry" button. FlatCam churned through the complex polygons of the ground plane in seconds. It was mathematically intense. The software was calculating thousands of vertices to ensure the milling bit navigated the intricate web of copper without leaving islands.
The machine moved with the grace of a Swiss watch. Because Elias had manually controlled the paths in CopperCam, the machine didn't make a single wasted movement. It engraved the fine traces, drilled the holes, and cut the outline. It was a symphony of subtractive manufacturing. CopperCam’s strength was the clean, predictable G-code it produced for the specific machine he was using.
Requires more clicks, but the result is mathematically perfect. Excellent for fine-pitch SMD work.
is open-source and entirely free. It is a "power user" tool designed to provide maximum control over every mathematical parameter of the PCB generation process. 2. User Interface and Ease of Use
