OK, EMC is very picky about the radius from the start point and the end point to the arc center being equal. I note that while your coordinates have 3 decimal places, the I and J only have two. Right there, that is going to cause problems, as the I and J can never represent the location of the arc center as accurately as the XY coords. See if your CAM program can be set to send more digits on the I and J coordinates.
You also have an odd form of the arc move, where you only have I and J words, no X or Y. I'm not sure if that is required, but maybe. I think the CAM file is trying to make full circles, so the X and Y coords are not actually necessary.
