Had my lathe down for a little maintenance and when I brought it back up, had a problem, can't get my head around it or find a solution.  If I tell the x axis to move 2.5 inches, it moves 2.5 inches.  If I tell the tool to take a .010 cut in diameter mode, it cuts .020.  If I tell it to cut .010 in radius mode, it cuts .020.  No matter what I do...  I don't get it.   Any ideas?
