Somehow I totally missed the part about threading being disabled in Demo mode.  Looks like that should fix me up, thanks fellas!


Not long after this I purchased a license and everything has been working great.....until yesterday.  Actually, I don't know when it started but I just noticed it yesterday.  It's back to doing the same thing again.  Any thoughts on why it would start doing that???

Thanks again for all of your help guys.

But it works, just not correctly.  Is that what is supposed to happen?

I recently noticed it wasn't a purchased copy, although the previous owner told me it was.  I will be purchasing a license anyway, just waiting to see if I should stick Mach3 or go to Mach4.

Here you go guys.  This is a custom xml that was created by the previous owner.  I've had this machine for over 6 months and so far it works well, this is the first problem (that wasn't operator error) I've come across to date.

I hope there is something in there that can help!

I'm still not sure why it would create the correct pitch (or at least what appears to be) on the first pass then go crazy on the remaining ones.  My program is set to take 8 passes and by the time it is done what is remaining does not resemble anything like a thread.

Please see the edited post.

What would the xml tell you that would help in this case?  Just curious.

[EDIT]

So, I got it working.....sort of.  The problem I have now is it will turn the correct thread pitch on the first pass only.  After that it runs at least 2x as fast and the thread gets all messed up.  Any idea what is causing that?

Any suggestions on how to re-write what I've been using?

Interesting, I guess that I've never seen that explicitly stated.   Just a Mach3 thing, I assume?

I meant to add that:

You can put anything in for the X positions and it acts the same way.  I'm actually trying to make a much smaller thread (M22x1.0) but when that didn't work the first thing I tried was increasing the X's by a large amount, no change.

I can post the xml file too if you need.  Thanks!!!
