How about leaving it in E-stop and moving the machine back and forth manually. Does it still get a position shift after moving and then moving back?
Or, is this just mechanical backlash? Are you saying the position shifts by ANOTHER .001" every time out and back, or just that one inch commanded moves are only .999" ?
