Re: [CAD_CAM_EDM_DRO] A stupid question

Hi Mariss,

RS274-X is basically a subset (extension) of Gcode. You'll see some
Gerber specific header blocks (lines) starting with '%' in your
example. Following that is a G54D12, which selects an aperture.
Following blocks end with '*', seems you've got a bunch without
CR/LF's. The X and Y values have the decimals omitted, and there are
several formats to know how to interpret them. Some have leading zeros,
some don't. Some are in "mills" (1/1000's), or other scales may be
used.

The last is a doc you can download.

With a few tweaks to my Gcode interpreter, I can read some Gerber's I
have.
