== Preliminary analysis by PR ==

   * Disconnecting the redundant chain does not improve the situation at
     all (if we really had to work like that, I would recommand to try a
     threshold of 6000).

   * short circuit of the connectors brings us back to a "smooth" situation: 
     smooth movement, and apparently much better reproducibility of stop
     positions.
