24.11.23 Tweak CY stages
------------------------
```
stage without load: slowest open loop motion:
#3out-14
#3out 15
(14-15% of nominal curttent ~275mA)
sometimes stuck and needs up to 35% !!! of nominal current to start mofing againg.
This is the drawback of brushes that do not provide a smooth current switching and continous torque
