The picture shows how the bit assembly mounts on the bit frame.
Note the position of the orange (arity 5) connectors of the programming hardware on the bit frame. These are positioned so that when the bit assembly is toggled all the way to one side, the connector ligns up in sucg a way that it would just clear the upright blue strut in the middle of the actuator rod side of the bitframe.
Here's how our partially assembled model looks with the bit assembly mounted.
