I think you'll find that the only unsupported rais it has are on the Z axis, but even having siad that there are FOUR of them spaced a good distance apart and held between FOUR X axis colums which in turn run on yet another FOUR supported rails.

Col.

Yes, that's what I am saying...

"Also that Z is, even if it uses ball screw, it is still using unsupported curtain rods."

Yes, four of them, but still. Also, the rest are pretty weak design, 12mm screws and 12mm supported rods that's not a lot at all. Add to that the pretty weak 60x20 extrusions... and it is nowhere near what I'd call "muscle".

It also looks like you'd have huge problems fitting that with a real spindle, other than the Kress, or possibly a tiny Dremel.
