Rough RT Location program question, what alignment

[[Mi...]]

So I have a pre-installed program for our rotary table (RT) 

After homing the CMM I need to redo the RT axis, the Rough RT Location is a program pre-installed and uses the center bore of the RT for it's position.

I have 2 circles in the features column and one is base alignment and the other is CMM alignment, they are within a few microns of each other in X and Y

Would one be more ideal to use than the other for establishing the rough location before doing an RT Axis program?

I don't think this will have any effect. It is only for the 'rough' location.

 

you should be fine.

Thanks, I just looked at the RT position and axis in the RT window and it is relative to base alignment once the RT Axis program is run with the ref spheres. And the X, Y location is different than the Rough RT Location and would be more exact.
