I asked about this, cuz I just KNEW I'd hear something novel and
interesting. I ask this same question of everyone I can that's built a
LARGE format router for this type of wood/foam work, and always marvel
at the diff. schemes people have used. And yeah, the dust from such
material really does seem to be a problem, potentially on both the
positioning mech & the slides.

Anyway, thanks for the word picture. Fascinating.
