Re: Problem with Dyna 2400 CNC milling machine (ARC Problem)

Elliott,
Maybe something benign after the 3 parms? Are the 3 statements on 3
following "lines" each with CR LF, or are the parms and arc command
on a single line ie "700 ARC [1][2][3] (CRLF)"
-or-
700 ARC (CRLF)
[1](CRLF)
[2](CRLF)
[3](CRLF)

Maybe the normal run mode and the line execute mode (mis)handle
these cases and grab the CRLF as a parm

I'm just trying to toss out ideas of what could hose and ascii
interpreter.
