Problem EMC2 and Solid - lathe

Hi
I was just wondering can you fellas help me out? I have a gcode generated by Solid for a part I am working on (and it has a fanuc post-processor, its not my Solid 2015 copy, and I cant mess with asking to explore and add one that is more suitable).
It s a small handle, and it has a radius end. Now, when I start EMC2 and make a first piece, it all goes OK. When starting the same piece again after the first one is done, when the finish move on the ball radius part is cut, instead of making a radius cut, the tools moves in a taper manner, straight line, and ruins the piece (and it shows that move on preview the same way, straight pink line). If I restart the EMC2, and run it again, it cuts radius once more. If I try the second, I get taper line again. Its not much of a deal, but its boring to restart it over and over again... I have attached the code file, maybe you can shed some lite to me?
Thanks

I think you need move first line (G0 X15 Z20) after initialize all g-code:

G0 X15 Z20
G0 T1M6G43
G0 G54 G40 G80 G97 G99

G0 X15 Z20
G0 X20 Z0.5

maybe this is due to the fact that the instrument compensation comes into effect

Thank you forcthe idea - I tried it, but it didnt work. Maybe its some problem with the controller itself (PRC 5 axis)?
