odd problem...

Hi,

I'm trying to run a program which runs just fine on the AHHA controller
and am getting some really disturbing problems.  At the end of the
program  I have a G02 Move to make a hole followed by a retract and then
I have a move to park the table for a part change.  Somewhere in the
last few lines of the program the Emc goes wild!!!  The stepper motors
freeze and make a screaming sound, the display counts to -several
hundred and/or displays NaN on all axes.  While this is happening
mousing to abort and clicking the escape key do nothing.  The f1, f2,
f3, f4, or f5 keys do nothing...  The only way out of the situation is
to mouse to "File" and mouse down to "Quit". Other than pulling the plug
that is...  This problem is NOT intermittent.  I can reproduce it every
time.

Of course I will study this in more detail tomorrow.

My contribution to the project seems to be "Fool Proof Testing" and I'm
just the fool to prove it!

What does NaN in the X, Y and Z axes display mean?  It kinda sounds like
when I was teased in third grade  "NaN, NaN, NaN!!!!"

Thanks,
