Managed to get the X Axis connected in. The flexures all seem to reach, and moving the Y Axis manually doesn't seem to cause any deflection viewed through the cheap microscope. New Z Tower is a drop-in replacement. Next stop, Y Axis. If I can get that done and tested in the next few days I can leave the git/wiki/Printables work to do on rainy days in hotels over the following week.

Work progresses on the Pantograph Driver. It's a bit unwieldy as-is, so I'm thinking of shortening the arms and lowering the mechanical advantage to 2:1. This should still be adequate for micron work, and I consider anything over +/-5mm movement as meeting the V0.05 design goals at this point. I'm trying to figure out ways of putting the complementary flexures to constrain the Drive Screw into either the motor bracket or the driver's frame. V0.03/4 Axis Drivers are prone to wiggle if not carefully assembled, and I want to eliminate that.
Another problem with long beams is that they require a long frame to support them, and that frame can flex. So the shorter I keep the beams, the more rigid the framework can be kept.
In other news, my Prusa XL is now operational, but it's a bit of a beast and my existing work table is clearly not up to it. I'm afraid I'll have to spend some time making a new one. This will give me multi-material printing though, which will enable a few more interesting experiments with flexures and so forth (though I do not want to make multi-material prints a requirement for the standard design).
