POSITION_FILE = position.txt That does the 'remembering'. The file format is internal to extreme precision, but I suspect that it doesn't account for which side of the backlash the machine is currently sitting at when you shut down emc. A simple + or - based on the last direction it moved, appended or comma separated from that axis's position and something in the position recovery code could process the + or - and then do a decent job of recovering a machine with say 5 thou of backlash comp in its setup, doing it to a less than a thou loss in accuracy.
