Sue is doing the 2 mil maintanence right now-and when she was almost done, #16 needle was 3/4 'down' and the machine said 'Z access time out', 'error in moving table' or something like that. She was able to go into maintainence tab and click 'head up' and 'bottom center' and then 'head up' again and it cleared it. Any ideas what went wrong? She hadn't hit the table arms or moved anything-is sitting there on a stool in front of it. Roland
