Mach cannot handle X-A arcs. Arcs have to be on the X-Y, X-Z or Y-Z planes.
To get around this you need to break the arcs into lots of short line segments. Go to c:\program files\sheetcam\posts. Make a copy of the post then edit the copy with a text editor. Look for
function arc()
Delete the whole function and replace it with this one:
function arc()
arcasmoves(0.1)
end
If the line segments are too long, reduce the number. While you are digging into the post, look at function rapid() and function move(). In both functions, change " Y" to " A".
In SheetCam, load the modified post and away you go, no more editing the G-code.
