You want absolute control over your toolpaths, enjoy scripting repetitive tasks via Python, or need advanced geometric manipulation.
: CopperCAM for quick one-off simple boards; FlatCAM for serious work. Coppercam Vs Flatcam
Automatically detects trace clearances and handles multi-pass isolation (milling wider channels around traces to prevent solder bridges) with a single setting. It excels at smoothly calculating paths around complex pad shapes. You want absolute control over your toolpaths, enjoy
