Trouble with Ref Sphere Position

[[To...]]

On RDS-XXT and get the warning below after attempting Reference Sphere Position. Any thoughts?

SDO Error -1117
No Convergence 1

I edited it to add the suggestions.

t could be a number of things. Follow this list:
1. Restart the computer with Calypso and power the CMM controller off for 30 seconds then power back on.
2. Make sure everything is clean: MasterProbe sphere, reference sphere, stylus adapter plate, probehead adapter plate mounting surface, and RDS adapter plate and mating surface (if using an RDS).
3. Make sure everything is tight: no loose spheres on MasterProbe or reference sphere, reference sphere clamped down solid.

Hopefully this helps. I have seen this in the past with a Vast XXT with RDS but have not experienced it with any other sensors.
