Milling double-sided PCBs on a 3040 CNC router HD

PCB design was done in KiCad, then converted to tool paths in FlatCAM via gerber & excellon file import, then sent to a Grbl-converted CNC router via grblControl. An accidental FOSS toolchain that worked best for me. If you have any questions, feel free to ask them in the comments.
