I can give you a specific recommendation based on your hardware. Share public link
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).
Milling printed circuit boards (PCBs) using a CNC router is a popular, chemical-free alternative to traditional acid etching. However, raw Gerber files from your EDA software (like KiCad, Eagle, or EasyEDA) cannot be read directly by a CNC machine. You need specialized CAM software to convert these design files into G-code toolpaths.
Steep learning curve. Because it unbundles the geometry from the CNC parameters, beginners often find the multi-step generation process confusing. However, it features a powerful built-in command-line console that allows advanced users to automate repetitive tasks using Tcl/Python scripting. 3. Isolation Routing and Tool Management Coppercam Vs Flatcam
: Can’t change UI or internal algorithms.
The learning curve for PCB milling can be steep, making software usability a critical factor. CopperCam: Visual and Guided
This is where the war gets bloody.
You want to write scripts to process your Gerber files automatically via a command line.
FlatCAM features a highly advanced "NCC" (Non-Copper Clearing) tool. It allows you to clear out massive areas of copper using multiple tools of descending sizes, maximizing efficiency and minimizing tool wear.
It handles isolation routing, drilling, and board cutouts with very little manual intervention. I can give you a specific recommendation based
Both programs excel at creating the paths that outline your traces. However, if you need to remove all excess copper between traces (known as "rubout" or copper clearing), their approaches differ. CopperCam calculates hatch-style clearing paths exceptionally fast. FlatCam offers multiple clearing patterns (ZigZag, Offset, Spiral), giving you finer control over surface finish and tool wear. Board Cutout (Profiling)
You wish to automate repetitive tasks completely using Python scripts and macros.
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 Milling printed circuit boards (PCBs) using a CNC
Both programs handle basic isolation routing, drilling, and board cutout (contouring), but they diverge significantly on advanced features. Rubout and Area Clearance
