You have to manually edit the G-code offsets or use an external program to shift the bottom layer.
Learn FlatCAM . The double-sided registration and ground plane optimization are essential for modern PCB design. While the learning curve is steeper, the community support (GitHub, Reddit r/hobbycnc) is excellent. Only buy CopperCAM if you find FlatCAM too slow on your old computer or if you exclusively make single-sided, vintage-style boards. Coppercam Vs Flatcam
FlatCAM (unquestionably). If you do double-sided boards, CopperCAM is a nightmare.

However, your CNC is only as good as the toolpath it receives. That is where converters come in. The two giants in this niche are CopperCAM (a long-standing paid software) and FlatCAM (the open-source champion). FlatCAM (unquestionably)
FlatCAM uses a .
Both produce reliable G‑code for common CNC routers (e.g., 3040, 3018, Shapeoko). For hobbyist use, FlatCAM is often sufficient and easier to start with; for professional PCB prototyping with complex isolation, CopperCAM’s automation can save time.
