~0.6mm, two layers of you use 0.3mm, people often use 0.2mm layer height though.

But I think mesh bed can handle this.

How does the printer compensate for precision loss do to movement? In industrial robotics, there is the concept of measuring the inprecissions in the machinery at any given point (direct measurement) and compensate that via variables in the robotic matrice. Is there something similar for printers?

I'm not sure. But in the end you are laying molten plastic on top of each other. Even with a perfect flat print surface you will have slightly uneven extrusion that will be noticeable on top down lighting.

What we have is Pressure Advanced. Where we stop extruding (as much) right before a corner. And we do that by doing some test prints with different values and eye balling it.

Also some firmwares like klipper have some math in it to compensate for heat expansion over time of the printers frame. Or something like that.

Most hobby printers do not compensate at all. There are input shaping to reduce vibration, and hacked together closed-loop upgrades, personally I haven't heard of any more sophisticated controls.
