Has anyone got this universal analog output circuit to work?

I'm not familiar with the circuit you reference, but it looks reasonable to me.
Can you specify more detailed what you "can't get it to work"?
Do you get any output at all?
If yes: what is the expected output vs. the measured output?
In which environment is the circuit expected to operate (what supply voltages, what load resistance/burden)?

O.K.
first: randomly altering values seldom does any good. Try to understand the circuit first. And on basic thing: Except under very rare circumstances (like superconductors) whenever there is a current, there is also a voltage. A current at the output can onlky flow if you add apath (ressitor) between the two output pins. Without load, there is no way for a current to flow and the circuit will just output max. voltage.

So which resistor did you change? In the schematic there is no resistor labeled gauge.

Also which wires "going through the center of the 1st OpAmp" are you talking about? I can't see any wires going through the OpAmp. Are we talking about the same schematic?

I recommedn you build the circuit on a breadboard, then you can experiment.
