Was this a heavy cut? I can easily imagine that taking a light cut first, it follows the commanded path. Then, at greeater depth, the cutting forces overload the servos and you get some different path. Are the following error limis set tight on that machine? If so, then the above theory is wrong. What radius was the G2 move? Is there any possibility there is some oddball character in that particular block of G-code that caused EMC to mis-interpret the command? I think that was reported recently, and it was a non-printing character inserted by a word processor.
I can imagine a case where a large radius arc has some short G1 moves after it. If the arc move was ignored for some reason, the next G1 move would appear to actually cut straight across the planned G2 start and end points.
