We’re seeing something like this in this issue which came from this thread.
In both your file and the one in the issue above, the gcode processor is creating parameters that require more precision than is available.
In your case, I think that MakerCam’s metric mode is causing the problem. Once you’ve loaded your SVG into MakerCam, use the Inch/MM button in the upper right corner to put MakerCam into Inch units, then calculate and export. I think that the file will run correctly then.
