Re: gcode comments

Ballendo,

So is the ';' not advisable? I want to implement the "stock size"
also. I have also read (NIST ?) that '/' can be used to "comment out" a
line. Is this in general acceptance? I like the '()' comments, easy to
parse. Although I'm inclined to put in "//" or "/* ... */" comments!
;>)

Jon E. brought up G92, which is something I had been looking for. His
description (thank you Jon) also reminded to put in code for limit and
home switches (not that I've got any switches mounted yet). Seems the
G92 also saves (to file) the offset of the "new coordinate" to the home,
so that it can be re-established (hope I got that right). What I want
to know, is/are there specific command(s) to "go home" and zero the X/Y
axis?
