AXIS X and Z view

Hi!
I use linuxcnc for modeling the processing time my Okuma LC lathe.
I have some difference in X layout.
The increment X coordinates is from UP to LOW (in AXIS window). But I need to make increment in Ocuma form LOW to UP (see pictures).
How can I change it?
The first Picture shows the current behaving of AXIS, the second how I need for Okuma modeling.

I tested both variants. Each has its own features and disadvantage. Thank you for help!
