Did you use "sudo"?
"sudo ./univdiags c030 bus"

For now just linking a button to perform touch off zero would be good, but I
need a way to control which axis. I have several buttons spare so I could use
one for each axis.

I've just 'wired' up a joystick to use as a pendant, based on the Simple Remote
Pendant article on the Wiki. As I only have two analogue inputs X & Y (the
third is normally used for throttle and does not self centre so I did not fancy
using that) I used the trigger button to select between X &

How about defaulting to the current position in the text box, and adding a
Zero button that zeros and submits in one click.

For a spindle P gain is not much help, as you need a non-zero PID
output even when at the set speed (and when the error is zero). That

Gene,
You have no Pgain, but Igain and Dgain. That's a problem. An all I and
D loop is almost always unstable.
Chances are you are going to want Pgain and a little Igain and little
Dgain(maybe.. if at all).
Start out by trying some Pgain and no Igain or Dgain and see what happens..

I currently have the commanded spindle velocity, NDI if it is supposed to
be rpms or what, essentially being fed thru the abs function directly into
the pid.0.command input.
I am sending the encoder.0.velocity thru the abs function also then into
pid.0.feedback. This voltage on the hal meter i

Perhaps the desired behavior can be triggered by the INI file.
I've given up using the touch off for setting the Z offset for the tool
table due to making so many mistakes with not having the correct touch
off selected in the menu and created a pyvcp button to do that. Next on
the list is a pyvcp button to touch off the Z of the material. I always
use a 0.
