If the calibration marks line up after running the calibration
program than the robot is ready for the application program
that is loaded the same as the calibration except the
directory and filename is specific for your machine.
If the Calibration marks do not line up:

attention to your accuracy.
b) Check the resolver values as compared to the written
values in the base next to the Axis 1 motor. See Chapter

c) Re-calibrate robot. See the Calibration Chapter for
procedures. If this works, note that there could be a
resolver problem occurring.

as per Chapter 9 - Motors and Resolver Circuitry.
