### Troubleshooting Rotary Table Problems

Problem | Readings across the part have a large error.
Solution | The tool length and rotary table location are not matched. Rerun the journal file while adjusting the rotary table center. Remember that the rotary table data will be reloaded from CncMachineData/<machine name>/rotab.dat when the machine is selected and restored when unselected.

For PC-DMIS NCI, the standard rotab.dat file in the installation directory is used.

If the results improve with center adjustment, try recalibrating the rotary table. If thermal drift is an issue, a local recalibration of the spindle length (Z) can be included in the PC-DMIS program by measuring a known location.

Problem | The path goes the wrong way
Solution | Clockwise/Counterclockwise is wrong in Rotary table setup.
Problem | Motion is not generated for the axis
Solutions | The rotary table is not enabled in PC-DMIS. You don’t have the rotary table option in your port lock. The Axis code in the Machine Definition is wrong.
Problem | Rotary table results do not track table angle for Fanuc controls
Solution | Verify that the wrong table angle is being included with every point in the journal file (or the machine readout if NCI). If it is, position the table at a known location and write a simple MDI program to read the location. For example #530 = # 5004

If the value of the arbitrary temporary variable #530 is wrong, review the controller / machine documentation to find the right address. #5004 is typical for the A axis, but the axes may not be linearly mapped against controller addresses. Change the value in the machine definition, save all, close down and restart PC-DMIS CNC Server.
