How to set up Z axis parking in Marlin?

Question

3D

Setting up Marlin firmware for Zav3d printer. Everything works fine except for parking the Z axis. The limit switch is at the bottom, respectively, the printer must bring the platform to the very bottom until it hits the switch there and drive back a certain number of steps. Before flashing, he did so successfully.
At the moment, if the platform at the beginning of the parking is close to the bottom, it successfully reaches, clicks the limit switch and goes back a little, the parking is successful. But if the platform was at the very top, then for some reason it does not reach the limit switch, but at a distance of a couple of centimeters from it it stops and slightly returns back, as if it had successfully clicked on the limit switch. When you repeat the parking, it goes down quite a bit and again repeats the rollback.
What firmware configuration setting will fix this issue? Is there a parking limit there? Couldn't find this setting myself.
