If you have had the cable off the front derailleur lately, chances are that it was reinstalled in the wrong location. Look at the end of the cable arm outboard of the cable attachment screw. If there is a groove on the end of the arm then the cable goes over the end of the arm and then to the attachment screw. This will change the ratio of the front derailleur enough so that it works for the triple.


Edit: After seeing the pics: In the first pic there is a tab sticking out over the retaining washer on the cable attach point. Go over the tab from the inside and then under the screw/washer.
