Problems with Tank zeroing

[Dummkopf 5]

Greetings all, i have a small problem some of you may be able to help me with. 

 

Im currently making a tank in Arma 3, and everything is complete bar texturing. however after doing some testing i discovered that the main gun isn't zeroing properly. It acts as if it doesnt get any range value from the rangefinder when T is pressed. And when manually zeroed its sometimes on point, sometimes off by 100's of meters. 

No matter what i try, moving the memory Lod points, tweaking the discretedistances and discretedistanceindex; my tanks main and coaxial guns are always of target. 

 

Here is a photo of my FCS in the vehicles config.

And here are the memory points that are used (the point at the end of the barrel is excluded from the image)

all the memory points are in the correct place, and the gun elevates and depresses, just not in perfect sync with the gunnersview; i assumed this was the problem initially but after moving the gunnersview around i couldn't get them to sync up. Not that it should matter if its just draws a line from the barrel to intersect the line the gunnersview draws. :-/

I have run out of ideas for what it might be, hopefully someone here can give me a hand. 
Cheers in advance.

gunBeg & gunEnd memory points should be lined up and from your screens it seems to be off by way cm. Press shift+e to manually set their coordinates in order to have it properly positioned

Thank you for replying. 

I lined them up using shift+e, (they where only decimal points off). 
The machine gun appears to zero now but the main gun still does not. 

Gunbeg and Gunend can be seen in this photo.

And ill upload a video in about an hour showing the problem in game if that helps to diagnose the issue.

here is the video of the issue in game, you can clearly see that the machine gun now zeros but the maingun still fires at a sharp angle down regardless of current zeroing.

Video is private. Can you post your config too?

Apologies, 
Here is the video now available to the public

My config is only a series of includes i assume your after the CfgVehicles component.

can you also past model.cfg? looks like you have desynced main gun with gunner view

Here is model.cfg.

you are rotating single point two times
first time with MainGun anim, since gunnerview is attached to otocHlaven & second time with this

 

            class MainGunOptics: MainGun {
                selection="gunnerview";
                axis="gunnerview";
            };

that creates discrepancy between muzzle & your view. Either attach gunnerview to otocVez or remove animation mentioned above

Brilliant, that fixed it up nicely. Thanks for the help.
