11s Di2 FD stuttering. Help!
Before i take it to the mechanic/friend who set it up, I figured I should ask the collective.
The setup is 11s Di2 Ultegra, I believe this is a mix of 1st and 2nd generation 11s. The junction box is external under the stem.
On today's ride, everything worked fine for a few miles...but then the FD stopped working properly. It was in the small ring, and an attempt to shift to the big ring was met by a "shudder" where the FD cage moves about 2mm towards the big ring, the servo motor seems to "try" to move a few times, and then the cage goes back to the original position. It will NOT shift to the large ring.
I can post a couple pics of the FD, i actually took a video of the action the FD takes but that cannot be posted.
