Help with placement of G112 in Lathe post

[exospex]

Hello all,

I was wondering if someone could tell me how to change the spot where the post starts the polar coordinate conversion.

 

existing code:

My machine does not like the c-axis output before the G112 is set. I need the g112 to be before the comp engage line. I started with the generic Fanuc 4 MT post. I'm new to modifying posts. Can anyone point me in the right direction?

 

Much appreciated.
