Greetings all;
Has anyone written an mdi script to run this autocal pid thing
described in the man page?
For some reason I've only been able to make it exersize z but once,
not very far, Those findings copied into the ini file result in Z
hunting at about 3/4 hz, by about .0004" non-stop.
Thanks all.
Cheers, Gene Heskett.
Petter has written a Python script you can find here:

This Hans, seems to lead to a huge list of stuff to dl, but nothing to
exec other that what's in the man page. Was there a script in the midst
of that wall of jpeg's that I missed?
Also here some useful information you might already read:
http://linuxcnc.org/docs/html/motion/pid-theory.html
And this I've seen many times. But as I wrote in the original post, I
was not able to get it to run again after I'd found some setting that
ran it about 1 mm up and down. I expected a 1 to be an inch but I guess
it was taken as metric.

Thanks Hans. Take care & stay well.
