I haven't bothered to read any other replies, but here's my advice.
Make sure the height and pitch are properly set. Once done, go ahead and try to shift to the big ring. From here you will adjust the H stop screw until it shifts to the big ring. Go ahead and shift all the way to your highest gear in the back (11t or 12t) and then begin the fine adjustment. I like to set the front derailleur cage centered on the big ring, and then slowly adjust the stop screw until the outside of the cage is closest to the chain without rubbing. This will prevent the system from over shifting while still allowing proper shifting between the small and big ring.
There has never been fine adjustment electronically for the front derailleur via the A junction box. There is a calibration process within the e-tube project software you download to your computer, but that has nothing to do with your scenario and hardly anyone ever needs to go through with that process. It just need the stop screws set properly.
Hope this helps.

Bit of help and advice please. I have put together my bike and fitted it with Ultegra 6870 Di2 (TT version with shifters on the brakes too) everything seemed to be going well, including the RD.
HOWEVER I am having trouble getting the FD right. I have got the low and high adjustments sorted fine with the 2mm Allen key, the problem lies with the electric adjustment when in the big chainring and biggest sprocket... the chain guide isn't far enough in to keep the chain on the big chain ring (due to the automatic FD adjustment) and it keeps dropping into the small chainring. I have switched the red button on to try and do as per instructions ie adjust the FD in micro amounts with the switches that usually move the FD.
Problem is that the FD doesn't seem to be electronically micro-adjusting with the red light on.
Any idea what I may be doing wrong?
Many thanks
