LT3080 output drop compensation

[MarkSvrc]

Hey guys, I am new here at the forum.

I am currently building a linear bench power supply whose main part, the voltage regulator, is the well-known lt3080 that e.g. Dave Jones used in his own design. I am running into a bit of trouble now as when i was testing the lt3080, the regulation seemed to be quite poor. While I have made sure to measure the voltage directly across the regulator tap and the COM of the circuit, i might have very well still miss something.
    But whatever the cause of the voltage drop may be, I have decided that just relying on the regulator to maintain the stabilized voltage and on the internal connections not to drop much of it is not the proper way to do it. So i was thinking and came up with the idea of providing the op amp follower with a voltage feedback for the inverting input directly from the OUTPUT regulator rail instead of the SET pin like you can see in the picture below.
As i am using pots to set voltage and the arduino to read the output terminal voltage ONLY, compensating for the voltage drop with it the digital way is not an option for me.
   What i want to ask you guys is, do you think that this confuration could really work and that the lt3080 would now provide better load regulation? I don't really need that much of a clean ramp up but don't want the output to overshoot significantly before the opamp  stabilizes itself. [ Specified attachment is not available ]

edit#1: For anyone having a similar issue with the regulation of LT3080 - I badly underestimated the importance of adding low ESR output Capacitance. Problem solved!

Quite frankly, I question your use of a breadboard here.
At least set up your circuit on a perfboard, anything less is complete rubbish.

Breadboards are for playing with a transistor, an LED and a couple of resistors, nothing else.
