It seems to me that adding rigidity to that upright must improve overall performance? Even in lots of the steel or aluminium builds i look at, the vertical support, seems prone to flex. Am I missing something?
Most builds seem to have the bearings, linear rails etc arranged vertically. Does it not make sense to have these rail systems horizontal, increasing the width of the Y axis supports?
