Re: Learning G Code

Brian, list,

A properly written G code interpreter will ignore "white space".
Therefore the lines (called blocks in g code):

G01 x5 f12
G01x5f12
G 0 1 x 5 f 1 2
G01 x5 f 1 2

will all be treated the same way.

G code is also SUPPOSED to ignore case, but many interpreters require
the use of upper case letters to work correctly. MaxNC is one example.

Hope this helps.

P.S. Yes, most gcode interpreters use ( ) around comments, and
everything within the parenthesis is ignored. An exception to this is
EMC's messaging system, which reads into the left "(", looking for
the letters MSG. This is something added by Tom Kramer while writing
the interpreter used in EMC, and is NOT standard g code...
