    I am wondering if this has ever been discussed at all.    I was staring at the machine contemplating how to expand the working area as much as possible and thought it might be possible to stack the x-axis motors on top of the y-axis motors thereby  removing the crossing gantry rails and allowing for the router to be mounted on a more (conventional?) center oriented gantry that x travels on a dual rail arrangement.  I see a few issues right off.   Is it too much weight for the Y axis motors?   It would need a means to support the  weight of the router/gantry, not to mention the loads in use.  And the Gantry Parts would need to be broken out in such a way that they could still be printed (or maybe CNC machined).     I guesstimate the rails would be spaced about 3 1/2″ -4″ apart (for US conduit) but they don’t necessarily have to be directly above one another.  Some angle set back could aid load distribution or even a three rail arrangement maybe  (conduit is cheap)?   Please shoot this idea down, so I don’t go making the wife crazy embarking on yet another project.   😉

    If you look at the remixes on thingiverse, someone did exactly this. There’s also the artisan3/pearcnc that did the same thing, good places to start if you need inspiration.
