homing z

I am currently working through the commissioning step by step.
When I click on the button (see picture) the printing plate moves upwards, so I have inverted all three Z-motors in the printer.cfg. now everything seems to work correctly, but ...
When homing, the printing plate now moves all the way down and does not stop “chattering”.
Are the buttons in Klipper wrong or am I thinking wrong or ...
Is the problem in front of the monitor?

Solution

So undo the Z motor inversion and you will be fine. The sound you heard when it hit the bottom was the motors trying to pull the plate through the bottom of the printer. I hope you did not leave it making that sound for very long, it can burn out the motors
