The first problem with the post should be solved with @xander.luciano input. 

As @Steinwerks mentions your clearly missing a key aspect to the setup.

 

I do not have your machine. But have extensive 5 Axis experience. And what I will describe may help you.

 

As for the 5 Axis setup... There are typically two basic methods to manage that.

 

 

1) The first method is very basic and static in nature. That is the WCS and part program zero would be static and fixed. And typically based on the intersection of the rotary tables. What that means is you must model your fixture and part to use that as part of it's math and setup. Next the setup on the machine must precisely match that setup. The post simply looks at the WCS as the absolute origin for all math output. If the Z Axis vector that is used for the setup remains the same there is no change in output with respect to rotary motion. IF you a Setup in Fusion CAM with a Z Axis vector and then have tool paths that have a different Z axis Vector (Tool Orientation) Then the two vectors are used by the post to calculate the correct rotations for output code.

This method typically works with Table on Table method and not necessarily for Head on Head 5 Axis machines.

 

In the most simplistic sense you should be able to setup both Fusion and your machine to work in this mode. It's more work on the front end as you must pre determine the center of rotation and build this into your Fusion CAM setup. And insure it matches the machines actual setup.

 

2) The second method uses TCP that is Tool Center Point Programming. Your machine must support it. And this allows for one origin to be established in the fusion side of things. On the machine side of things your setup can be anywhere like a normal use of fixture offsets. The post still calculates the differences in vectors and the output looks pretty similar as far as rotary angles are concerned. But the output WCS does not have to be the rotary intersection. The machine handles rotary compensation in this case. There are many other advanced 5 Axis modes depending on the control manufacturer and machine builder. As seen below in this video

I would get with your SurfCam programmer and try to mimic his exact setup in both software and then on the machine.

 

In the post below are a couple examples here of Fusion CAM files for 5 Axis 3+2 style programming using mehod 1) above.

I hope this helps.
