After changing toll position

Hello, I’m working on a PP for a Linux CNC System. I have used a FANUC PP and did some changes. 

But I still got a problem, after changing a tool. 
The zmax_pos = 95 what the CNC is capable of in z.
Everytime a tool is changed, the the next zpos = znext which is 120.
I can’t find where znext is defined.

I also don’t know where xnext and ynext is coming from, but there is no issue with those.

As shown in the picture. 

Thanks a lot for your help. 
  

can you post your INI file.
