How to change the rotary axis to output + and - for CW and CCW rotation?

Hello,

 

I have a 5 axis CNC Machine controlled by Linuxcnc (XYZAC and C is the wrapped axis) but it requires the C axis to output "-" if i want to rotate the axis CCW for example:

 

C90

C-0

 

which rotates the axis 90° CW and then 90° CCW back to 0° 

 

i tried copying snippets from the Postprocessor from (https://forums.autodesk.com/t5/hsm-post-processor-forum/4th-axis-vmc-standard-dpm-feedrate-output/m-...) but it ended in syntax errors and stuff

 

i have uploaded my Postprocessor and a example Program (just to verify correct motion)

 

if someone could help me i would be happy 🙂
