Closed loop @ bin2

We start the bin2 loop but there is a kind of waffle mode which comes out and is not seen in the slopes.

Moving the camera lens gets rid of this mode, but makes the loop unstable.

It appears that the IM calibration has been done without centering the camera lens before using the automatic loop, so we have to take another one.
