Problem with B axis in TNC640

[jaroslaw.ostrowskiVMVJM]

Hello

I have a 5x machine with a rotating axle C and a tilting axis B on TNC640. When I generate in Fusion 360 indexed programs, the B axis always turns to plus. But I often have to generate a mirror prgogram, e.g. relative to YZ. Fusion then turns the axle +B instead of simply twisting the axis -B. In the attached picture you can see that the hole is far from the operator. It will be closer in the mirror part and it will cause a collision with the machine. I tried Cycl19 and Spatial Plane. The same effect +B. I use a postprocessor from the Fusion library. Maybe it's a problem of Fusion 360 himself. Maybe someone has an idea. Sorry for my english.

Have you tried changing the preference tilt in the machine configuration?

Hello.

I have not changed the definition of the machine. I was changing the postprocessor. Now I changed the definition of the machine and it works. Turns the -B axis. It seems that for normal part machining, this setting must be positive and negative for the mirror. This is a solution. However, I would prefer to be able to set it via a postprocessor.
Thank you

Could you possibly upload a file where you are using a mirrored program so we can have a look for a better solution?

Hello

I am sending manufacturing model from the picture. I removed most of the operations.
