Tool is not tracing toolpath

[Metals and materials]

Hello all, 

I am new to Mastercam. I just started learning mastercam 4th axis from the pdf of mastercam 5axis. THe tool in 2axis, follows the 2D path perfectly. But in 4th axis, the path of tool and the tool path does not match. I am attaching few screenshots, to understand this better. 

ss_1 : toolpath looks good. It's in the wireframe, proper place.      ss_2  Going to verify now.    ss_3 Is not starting where I wanted.       

ss_5 is completed pocket.    ss_4 the axis rotated and now the pocket is in the place. 

 

What is happening here?

This tutorial is an axis substitution then a rolldie Chook

Can you attach your file?

Yes, sure, here it is. 

 

AXIS SUBSTITUTION - UNROLL THE GEOMETRY.mcam

Everything looks correct except the Lead In/ Out Arc Entry and Exit. Then they get you to change the rough stepover to 20%. Then do the rolldie operation.

The tool just looks like it is cutting in the wrong location but after the verify finishes it looks correct.

That's the main issue I am having tough time understanding. why tool comes down at the wrong location? Is it because I did something wrong or because wireframe cannot rotate like the part rotates, gets cut, and goes back to original position?

It is just a graphics issue I believe. The Backplot shows it correctly. Set the Backplot Options to simulate rotary axis and axis substitution.

Ohh okay okay! I really really appreciate your help!
