about the 5/8/' morse origin somewhere, but that also seems like an arbitrary

The issue with sharing encoder signals with both the
Gecko servo driver and the PC comes from the fact
that the step and direction signals into the Gecko
are optically isolated and the encoder and its signal
exist on the other side of the isolation barrier.
