Hi everyone,
I'm new to the forum and, as of a month and a half ago, new to using Mach 3. My primary duty at work is as a manual machinist, but I have also had some training at my local community college using CNC mills and lathes. My company recently bought a Velox CNC router to perform some rework and due to the time frame they gave us, I only had a couple of days to learn how the Mach 3 control software works. So far, I'm pretty pleased with it, but we have run into an issue that seems like it could be a bug in the software.
What's happening is that occasionally our router will just stop in the middle of our last X,Y movement at the end of the program. The message that is displayed in the status field is: "Cycle pause.. No jogging No reverse!!" This has happened to us at least once a week. No one has accidentally hit anything on the keyboard, nor have we intentionally clicked on the feedhold button. We've probably run this program hundreds of times without any other incidents and there's no way of knowing when the machine is going to freeze up on us. I'm hoping that someone here can help us shed a little light on this problem.
We're running Mach 3 version R3.043.022 on a computer running Windows 7. I had to write the code for our program myself because we don't have a CAM program. I'm not ruling out the possibility that something in the code might be the problem, but as I've said we've run this program a lot and the issue seems very hit or miss. Here's the code we've been using in case anyone can identify something that might be amiss. The line in red is where we've been seeing the machine freeze up.
I appreciate any help or suggestions you may have to offer.

Might be the M5 in a line with an axis move. ? ? ?
and ... a spin down delay set in your Spindle Set-up dialog.
I'd try it with the M5 on it's own line ... or maybe with the M30.

Also, do you have a physical feed hold button? If so, how is it connected to mach? Might be picking up noise on that input but I would think it would be a little more random if that's it.

Thanks Overloaded, I'll see how the M5 works on it's own line. I'll just have to wait until the staff we have running the machine goes to lunch so I can swap out the code.
Chaoticone, we don't have a physical feed hold button hooked up. We just have the onscreen one for use.
Thanks for the replies. I'll let you know how things work out.
