That code looks a bit strange.. Not sure what your trying to accomplish with it. Are you trying to move in a YZ arc? If so, then you should have G19 enabled (moving in the YZ plane) then your code should be something like G3 Y4.15 Z-.4666 Jxxx K-.4688 Where J would be the distance along the Y axis to center of the circle, and K is the distance along the Z axis to center of the circle.
Read up in the haas manual on how the G02/G03 commands work, and also about the G17,G18,G19 plane specifications.
Just when you thought you had it all figured out, all hell breaks loose..
