When is someone going to implement a permanently level bed? One sturdy enough to maintain calibration.

What is the trick here?

apparently the gear motor with worm turns the gear the gear has a component that triggers the 3 releases in its turn one at a time. while that point is released the nozzle pushes it down to 0 with nozzle in place the gear continues around re engaging the lock and then the next 2 points. the lock must be friction based
