Its been what, 2 years since you recommended we disconnect that, which I 
did like this, fixing my problems with something related to following 
errors. From TLM's .hal file:

net     x-vel-cmd      <=  joint.0.vel-cmd # => pid.x.command-deriv
and
net     z-vel-cmd      <=  joint.1.vel-cmd # => pid.z.command-deriv

I found those nets commented out in the GO704 configs

No pid's are used in the sheldon or 6040.  Should I be now?

Is there now a better way or was that an original stepconfig bug?

Their has been quite a bit of water under the bridge since then.
