Auto home

Hello,
It is the first time I use my printer and when I press Auto Home, the Z axis goes up instead of going down...
When I move Z axis, the nozzle goes up but when I come back to 0 on the screen, nothing happens, the nozzle does not come back down...
It is as if the command to go down does not work...
Does someone have an idea to what I did wrong?
Thank you !
Sandrine

1.Try to upload the firmware again
2.Check the A4988 broken or not(You can swap them)
