I am in the beginning stages of designing my first CNC router setup and I am debating as to whether to have a moving gantry layout or having a fixed gantry and moving bed.
The materials I plan on cutting with my router would be mostly plastic and aluminum. My initial feeling is that a fixed gantry with sliding x table would provide a more rigid support for the Y, Z axis when cutting harder materials, but the moving gantry style seems to be the predominant style on these boards.
What is the advantage/disadvantage of each? I know that the fixed gantry design would inherently have a larger table footprint, but that is not necesarily important. Size wise the working area (cut zone) would be about 24" x 24".
The great vault of knowledge and experience on this board would be greatly appreciated.
Thanks
