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.
