Is this a router? plasma? laser?
Dont always go with what you see in the toolpath window it may not be true to what it will actually cut, Specially if you are simulating the toolpath, instead of a cylce start.
another thing. the setting you are using on CV stop angle wont do anything to 90º corners, if you want it to stop on 90º corners the setting would have to be 89.
My suggestion.
1. Leave settings as they were (CV on, CV dist and angle turned off) and cut a part.
2 Put a G61 in the begining of yout g-code and cut a part.
3. Put a G64 in the gcode, and turn on the CV dist and angle, put something like 89 in the angle, and 0.5 in the distance, and cut a part.

Compare the 3 and see which one is better.
My guess is that the part in suggestion 1 will have the most roundness but will cut faster, and with less shaking of your machine. Part 2 should cut without rounding but slower and with more machine shaking. Part 3 should be the lesser of two evils.

Chaoticone ,
Problem was our router was keep taking shortcuts and making ''evil edges  ::)  '' we were trying everything  but finally we solved with all the help from you guys!
Actually we  tought we were chanceing the parameters from the machscreen but  it makes no effect at all (switching between g61/g64 -exact stop/constant velocity )
Somehow we manage to embed those codes trough the actual machine code and it works (i think the screen design has a problem maybe the buttons are not assigned ? or whatever )
 we solved thank you  again 
for the future reference , if any one faces something like that(please see the past posts) please also keep that in mind sometimes the buttons you think works actually may be disabled! so go old school and add  the damn code  in your lines !!! ;D 

thanx all!

Baran,
From past experience, all buttons in mach work. But in the default mach screen, i beleive there is no CV button, its just a LED.
I mught be mistaken, but if there is and you press it on, and you have a G61 on your code, it will over ride it, and vise versa.

So were your problems fixed by turning CV off? Did you machine handle the shaking well? what about cutting speed?

Fernando

Fernando,
    That is right about a G61 over riding the button.

Good job. ;D
