Got a TM2 with AM3 and I am getting random issues when cutting lettering and circles. On circles it will cut out of round by jogging in a little so its not perfectly round. Its not the file as I can cut same file mult times and it changes places or cuts normally. Its never in same location either. Also lettering it will jog one letter up or down a little. Everything is clean rails and cassette, spur gears tight no play in table. I have alot of hours on it. Only thing I am not sure on is the cassette but it moves fine by hand. Example is the "O"'s and the "D" below. The are moved up and away from the other side of the text. It does this randomly. I can cut the same file again and it will do it on another letter. The other picture is of a circle how it joggs on the cut path. Any ideas?
