First post and I'm intending to start my first cnc build soon, I'm starting to design at the moment but something is puzzling me.

Having a very rigid gantry seems to be crucial but all the designs I've seen seem to try and accomplish this by adding huge amounts of material and weight to the gantry which then means you have to start upgrading or doubling up on motors etc.

Has anyone done a gantry design by laminating aluminium honeycomb between either aluminium sheet or carbon fibre?

It would seem to provide a far more rigid solution for any given weight when compared to the mdf/plywood/aluminium builds, am I missing something blindingly obvious or would this be worth pursuing?

The cost shouldn't be that excessive if you look at the cost of honeycomb from easycomposites.
