Classic CNC routers use massive frame and rails to eliminate play. How is this thing supposed to be precise if it just hangs on four cables?

Cables are kevlar-reinforced belts and the machine knows how long they are and how much tension in on them so it's relatively easy to compute how much they'd stretch under most conditions.

The frame these belts are mounted on still needs to be stiff, though. A concrete floor is a pretty good option.
