Post Processor For 4th Axis B Rotations Issues

Good morning everyone.

 

I have been trying to develop a post processor for Kitamura horizontal machines.

We bought a fusion 360 license about a year ago and I was able to hack together the HAAS A-Axis post to get us running but its time to develop a more stable post with all the proper functions.

 

I started with the generic Fanuc post and was able to get it to output the proper codes for a lot of the machines functions.

 

My issue right now is that it will not output negative B axis rotations.

 

I can do everything just fine in the positive B axis rotations. But when it needs to rotate to B-90.0 it outputs a B90.0 code instead.

 

I have made a dummy file to show my issue. I face and drill on both B90 and B-90 faces. 

Both rotations go to B90.0

 

I have attached my dummy Fusion file, my post processor, and the .nc file that gets posted when I output the code to a memory stick.

 

I have named the toolpaths in the file so that when you post out the program you can see what rotation is supposed to be called out in the code. I have also attached 2 photos of that I am talking about here.

 

I hope there are some post processor experts on here that can help me out.  

@seth.madore do you know of anyone on the Fusion team who can help me out?
