No, I only use the MicroFence adapters, for the most part, for "circle" work, to-date....I originally intended to do some inlay banding, but haven't found a worthy project yet.
I use my MicroFence on the Festool Guide Rails all the time for dados. I gave up using dado blades on the saw a while back because rarely do I find dead flat ply, and consequently the dados would vary in depth. Not so anymore using my 1400 and the MicroFence. Expensive yes, but extremely accurate and versatile.
