From the website: "Whilst this article features a Shimano 105 front derailleur, the adjustment process is the same for all mechanical front derailleurs from the following Shimano group sets;
- Shimano Dura-Ace – R9100 front derailleur (FD-R9100)
- Shimano Ultegra – R8000 front derailleur (FD-R8000)
- Shimano 105 – R7000 front derailleur (FD-R7000)
- Shimano GRX – front derailleur (FD-RX810, FD-RX400)"
Thanks for the link. However it doesn't really address initial setup of the FD Which is where most of my problem lies. It just says that if the cable is too tight loosen it and if too loose just tighten it. Duh! It is not easy to do this in small increments with a "fuzzy" inner cable.
Reading the comments the author mentioned that the initial cable setting interacts with the "H" limit screw. Now that is about as non-intuitive as you can get! So the H limit has to be set correctly before the cable is tightened. This is TOTALLY missing from the Shimano Dealer Manual... and likely most of my problem.
Luckily the author covers this in a separate article on FD installation that can be found here:

When you attach a new cable you have to reset at least the cable tension and "H" limit screw and then set trhe "L" screw to position the outside of the cage with the outside of the big ring teeth.
I'll try to have another go at this tomorrow in the daylight.
