R7000 front derailleur adjustment?
The new breed of Shimano FDs are challenging me. The older Ultegra/105 seemed really easy to tweak. I知 getting just a tiny bit of rub at the cage when in the 52/12 combo, but what I知 reading about the R7000 FD seems to indicate I should NOT just adjust the limit screw. Is this correct? Do I have to go back to zero and undo the cable and then re-setup the whole thing to get this minor rub sorted out?

Yes, these "toggle" style derailleurs are different from the older stuff in some ways.
In addition to the Shimano tech documents, I found these very useful when working on my R7000 front derailleur for the first time:
Cycling Obsession - Modern Shimano Front Derailleur Adjustment Guide
Cycling Obsession - Installation Guide for Shimano Front Derailleurs
The second document includes some instructions for how to "reset" a derailleur that has already been installed on a bike, which puts one in a better position to start going through the set-up procedure. I had to go through that when sorting things out on a new-to-me secondhand bike.
Although I might go through the whole procedure, the "adjustment guide" article does specifically discuss, in the "troubleshooting" section, the possible need for fine-tuning to address the problem you describe, using some combination of cable tension adjustment and high adjustment.

if I read the manual correctly r7000 is like the r8000 and they are different from previous generation in terms of adjustment.
I had to re read the manuual I down loaded https://si.shimano.com/en/pdfs/dm/RA...001-05-ENG.pdf in order to do it, but once I understood it is easy
Just follow the steps in the manual, but basically 1) adjust derailler heigth and cage to large chainring 2) adjust low/high 3) set shifter to all the way low, 4) pull cable tight and secure 5) shift all the way to high 6) one trim click low 7) then alighn the adjustment line using the hex head adjuster on top of the derailler

Thanks all for these tips!!! [QUOTE
=oldbobcat;22888291]These guides look excellent. One of the issues I've had when setting these up is getting enough initial cable tension. Unlike the old 10-speed derailleurs that required a bit of slack for effective downshifting, these take a tighter shift cable. Make sure the ferrules are fully set before clamping the cable. For additional tension, try this hack, used by many mechanics. Just before clamping the cable, place a screwdriver or 4mm hex wrench between the derailleur cage and the frame to hold it away from the low limit screw a bit. You won't have to pull on the cable so hard.[/QUOTE]

Keep in mind that these derailleurs will only work as advertised on a current Shimano crank. On aftermarket cranks you'll lose the inner most trim position due to the narrower chainring spacing.
