Hi DD, I've seen you state several places that belt-coupled screws help maintain orthogonality of the axes, but I'm not getting it.
Isn't the direction of the z-axis defined by the linear support (rail/rods)? If you rotate one screw alone, that will raise/lower that side, tilting the platform and potentially binding the screws.
But even tilted, turning both screws in sync will still move the platform along the same vector - and the tilt can be compensated through bed leveling.
What am I missing here?
