EMC Hangs when loading this code???? was created by bqgray
So,
I guess I'm in the process of becoming less of a newbie.
I've written a piece of g-code (o-code?). The purpose of this code is to put a surface on a given area. I have been hoping to make it really accessable, so that the primary program variables will be easy to alter for any user.
I wrote the code, and now I would like to load it into my machine, but when I try the EMC2 Axis interface simply hangs. It is a very simple piece of code (at least from a programming perspective)
What can I do to make this load/work?
Thanks,
Bill

I've done some more research, and it would seem that Axis is not really able to handle the "while" loop at all?
Below is my new test code. If I simple remove the while statement, things load up fine. With the while statement Axis hangs. Seems that there might be a bug here? Or am I missing something?
Thanks,

Well, a little more beating my head against this I seem to have something working.
All I can say is that the code seems to be real picky about capitalization and numbers.
Using capital O and three digit O numbers such as O123 not o2 appears to make the whole show work.
Pretty weird that that doesn't through an error and instead just makes the system hang, but whatever.
Thanks,
Bill

I ran the code above and had no problems. It seemed to run one loop. No matter if I use o2, o200 or O200 I still get one loop. Trying to run the first example must have an infinite loop as it never seems to finish loading when I hit escape it stops but is incomplete. Single stepping the second code it goes through the loop only once.
