Z axis not working

Hi,
just downloaded and tried some different releases but i always have the same problem with Z Axis
on my Ender 3 with SKR mini e3 v2 and bl touch on z probe pin - dual z.
if i home axis, the Z AXIS just move up, probe in the air and STOPPED appears on the screen.
It seems it doesn’t go in negative position.
The same i found in the move menu…can’t move z axis in negative position.
thanx

So what I ended up doing was building my own firmware for it. Instead of using the builder. I used the firmware builder for 2 different boards the BTT e3 mini V2.0 and my Creality 4.2.2 board and both of them did the same thing when trying to Home Z I think the problem may be in the builder, because you can choose the bl touch port, but not the actual pin. On 4.2.2 board the pin needs to be pb1 and on the BTT board it is PC14 once I wrote my own firmware problem was solved
