I've had a few servo motors who's encoders did not have an index wire, but the encoder had all of the index hardware populated, and simply adding the necessary wire to connect it enabled it.

Seems like it would be handy. It appears to have an index slot in the glass plate , but not enough wires π€π€π€ OTOH, for XYZ, not a hard and > fast requirement as long as the home switches are good.
