This page describes the status of the fishing rods and provides characterization information measured at the time of assembly.
It's important to bear in mind that the reported range of the stepper motor in number of steps is not expected to be accurate and it's useful only as a guideline:
- Whenever the stepper driver is reset the posion of the motor (measured in number of steps from a zero) is lost and begins counting from zero wherever its physical position is.
- Inaccuracies may arise when a stepper motor reaches the physical end of range because the driver still considers valid the requested position even when its beyond the physcal limit.
With respecto to the LVDT range limits, those may change with temperature.

- The number of steps for the stepper motor seem relatively small. In principle there's nothing wrong with this but let's point this out.
