Doug It sounds like the FD does not move far enough to the inside to shift to the granny of a triple with the low adjustment screw all the way out. A possibility is your FD is designed for a front chain line greater than you actual front chain line. FD have about 20mm of sideway motion and if the front chain lines are mismatched AND the crank ring spacing is > 5mm, the FD can move to the granny.
Suggestion: Measure the front chain line to the middle chain ring and compare it to the design value for the FD Measure the front chain line of the granny ring. If the middle - granny is > 5mm (like 7 to 8 mm on a Sugino XD/TD crank you may have a problem. Possible solution: Get an old triple FD designed for a 45 mm front chain line, like a FD-MT-60 form the 80's. I bought a Sora FD-3030b (9spd) with a FCL of 45m and it shifts a Sugino TD-2 46-36-26 with problem. The XT-FD-M781-AX6S had a FCL of about 50mm and could not shift to the 28T granny. TD-2 ring spacing is 8mm Outer to Middle and 5mm Inner to Small. I bought the Sora from Universal Cycles for $34.88. My FD-MT60 also shifted it fine, part of a Biopace crank on a 88 Schwinn Voyaguer.
