Conventional design of moving gantry type m/c s is generally type A in my sketch below - short beam - nice and rigid and within reason - the long axis can be quite long...
I like to push things or at least try!
so type B in my sketch below has the long axis in the other plane and means a longer and bit bigger section beam is used... I'm wondering about going down this route perhaps myself - I'll make clear that I intend to use two Acme screws each end of the long beam.
what are the pro's and cons of these basic designs?
A long beam means you can hang more routing heads on it? more accessible ?
