I started my machine earlier today and set up a job, the part was good. I shut the machine down and when I came back later the Y got an over travel alarm in the middle of homing. I shut down the machine and held down the q/p can buttons and it homed. I then ran a part and the Y positions were shifted in the Y+ directions. For a test I made a short program to home all 3 axis. It ran 3 times in auto with no problems. I then tried zero return manually and Y got an error every time. What is causing this? The home switch? A skipping motor encoder? Why does it complete the homing sequence in auto and not manual operation? My encoder on the Y motor is the A860-0300-T001 2000P model. Thanks Dan.
