Hello, I’ve just shortened my chain as it was too long but now its making a loud grinding sound. I’ve readjusted the B limit too but this hasn’t helped. Its 105 di2 with an ultegra 11-30 if that helps.
I only shortened it a couple links as the bike shop said its too long (used a chain length calculator and the small chainring big cog method to be sure)
It seems to be scraping on something possibly? I cant seem to see were it could be tho
Any help is appreciated, thanks!

Classic! You routed the chain incorrectly through the rear derailleur cage. It’s rubbing on the small tab that it needs to go on the other side of.
Good old cage routing mistake😅all time classic!
I’ve been working on bikes for a couple decades and I still occasionally do that. Easy mistake.
