I opened the first pdf and it has an article on pid tuning. It suggests
applying a square wave command and tuning from that. How hard is it to
generate a square wave in emc? Will this require hal trickery or can it be
done with GCode?

Frank,
I have a little thing called a battery-box, that I build years ago (exept it
has not got a battery, it just hooks in the +-15V of the drive).
In any case its sole purpose is to generate a square wave with a
sufficiently slow period that the table moves while I can observe the result
on an
So far, this person (?) has only mailed twice, no real contributions,
just spam. In such cases, the most efficient thing to do is to cancel or
kick him out and watch him reappear or complain, if he is a real list
follower.

You can do that in EMC2 without special tools:

There are examples of this and other buttons on the forum in the Hal

Chris taught me to tune emc2 axes with motion provided by gcode.
Set your following error sloppy enough to let your machine run untuned, but
tight enough that if it runs away emc will stop it. Run axis (or your gui of
choice), run halcmd (for interactively setting pid gains), run halscope
The only thing I would add - set G61 (exact stop mode) to be sure emc is
using the max acceleration in the ini. (Thanks ChrisR for pointing that
out).

Andy, I gotta ask.. how many counts is your encoder? More
specifically, how fine does an encoder need to be, to do what you do.
The lathe encoder is 400 counts (100 slots) and the milling encoder is
200 counts (50 slots).

It seems to me that an external square signal might cause an overly
aggressive acceleration.
Only when you want to impress the neighbours with a shaking building . . .
A few millivolt of signal at about 50 Hz or so, depending on the bandwidth
of the system, is enough.
Just check at a slightly

Christian,
it could be that you need to invert the axis. You could do this in the
configuration wizard on the setup page for pinouts. I think that there is a
checkbox labeled 'invert'

Which image, which text? Is this a screen problem or a machine problem?
