I would argue that the genius in the prusa printer is not directly that its calibrated - its in little details that become obvious once you have experience them during upgrades of your own printer. Say the magnetic bed and the elimination of bed springs. Or where exactly stepper motors are placed. Details of cooling fan ducting. If you add good calibration to that you end up with a very well working printer. this means that if you copy it exactly the printer will work well even with inferior parts. So companies that are cheap and innovate are punished and do not know why exactly.
