The problem with both Incra fences is that they cannot go -under- the Festool track without limiting the minimum thickness of the material to cut. Having the fence going under the track is important for supporting the material when it is short.
I do realize this is an old thread . . .
I use the Incra Fence attached directly to the MFT/3 top, but installed a 3/16 inch aluminum flat bar under the Incra Fence that also sits proud of the front face of Incra Fence. The flat bar extends under the Festool Rail to within 5 mm of the kerf, providing support for material under the fence. The flat bar is the real fence, being aligned to bench dogs in the same way as shown in the OP's image. The Incra Fence only provides the repeatable positioning with the stop. I would like to integrate Incra positioning into an extrusion other than the Incra Fence, but I have not found a suitable solution.
