Seems to me that mounting the axis drive motors on posts could result in wind up of the mount, intoducing inaccuracy and possible resonance. Why not combine 2 of the posts into a flat plate (tons of beam strength, no torsional flex) with 1 plate for the top holes and 1 for the bottom, which would have the added benefit of keeping most of the chips away from the coupling and motor bearing. I understand that it's entertaining to watch the coupling turn during an operation but I'm not talking about enclosing it completely.
