Mechanically etching PCB boards

Process to get PCB boards made.

– Design in Eagle, and export from the CAM module in Eagle layers 16, 17, 18, 20, as GERBER_RS274X
РAlso export layers 44 and 45  as EXCELLON
– Import gerber file and excellon fine in CircuitCam
– Isolate as required (using only small and standard tools), and batch export DXF ;this outputs 4 files (small tool path DXF, Standard tool path DXF, Drill DXF and border DXF)
– Import DXF files in CNC USB Controller software, and export “Toolpath to G-code”
– Each DXF file will have a .nc file to be cut with the appropriate tool.
