MAESTRO - MORBIDELLI PROBLEMS

After a 3d routing operations the head rise up to the maximum Z position.(G153 G0 Z0 - in ISO code)
Maestro don't accept value to the "safety quota" (if I write a value then the software erase it)
The machine spent a lot of time to do this unnecessary movement.(20 mm over the material top it's enough).
May be I can modify the post processors (NCI.cfg) file but i don't know where to modify and how ....
Please help me !
