My front shifting is still not working properly. I believe the problem

53 tooth ring, which worked nicely with my original Microshift

because the Isis bottom bracket was narrower. The new Shimano
derailleur does not like shifting up the 50 tooth ring, so now I
ordered a Microshift derailleur that says it's made for a 50 tooth
chain ring.
Does anyone else have this much trouble getting a front deraileur to
work?

In a mix-and-match system that could be tedious. Nothing
wrong inherently with combining your favorite brands BTW.
Set up the changer to be 2~3mm above the outer ring teeth at
the closest point.
Front changers for compact/triple are frequently optimized
for 48 outer, road sometimes for 53 outer. More than just
the curvature of the outer cage, the various lips and folds
of the inner plate are in different places and the outside
front tip is shaped differently. (that's a critical part as
it lands the chain on the ring).
Besides height, also check that the derailleur cage in in
the same plane as the chainrings when viewed from above.
Askew a couple of degrees will shift poorly.
If you think your system would shift better with wider
chainline, ISIS can have a spacer between RH cup and frame
face, 2mm or 3mm are common.
Ajdrew, is it true that Shimqano and Capagnolo 11 speeds have the same spacing between the cogws on the cassette?
