While I'm fiddling with the XY Flexure Table I decided to eliminate an issue with the way the Y axis is driven. Because of the way I originally developed Maus, the Table has just been a passive thing that allows the Stage to move in the XY plane. Long, thin flexures attached the X & Y Axis Drivers directly to the Stage. Unfortunately movement on the X axis would then influence movement on the Y axis as the flexures bent to accommodate each other. The effect was small, but there was no need for it to be there other than it being the way I threw the thing together. So now I'm driving the Y flexures on the table like this:

Still being developed (forgot to recess the screw heads for a start), but the Y Transfer Bar now pushes on the Y flexures in the frame. As these are isolated from the X flexure system, the movement of the Y axis will now be linear. This doesn't mean that the movement of the Stage will be perfectly linear yet, because the X Flexure will bring its own influence to the party. 

Working on that. Github update not quite ready yet.
