Calibrate Tips vs ScanRDV. Combined?

I am getting into scanning on 3 of the CMM machines I have, they all support scanning. My question is on the calibration and how i should approach it. I have autocalibration programs that we use to calibrate our whole library at once. I currently just calibrate them all using the standard calibrate tips routine. However i was made aware of the ScanRDV and am wondering if i need to do both routines? or is doing the ScanRDV covers both? It looks like when i run the ScanRDV it takes hits as well.

  • I'm not an expert on this so take this advice with a grain of salt. Are you selecting "DCC+DCC"?  If so, then I think it will do what you describe and take hits points as well, but will only report the ScanRDV deviation.  Try selecting "DCC", then it will just do the ScanRDV without the hit points.  When I calibrate, I only use "DCC+DCC" for the Primary Tip and "DCC" for everything else.  I do a regular calibration first, then a ScanRDV, both using the "DCC" option.

    Also, do you know if your CMM is a chrome model?  If it is, then uncheck "TRAX Calibration" and you shouldn't have to do a ScanRDV.  It will scan the sphere during normal calibration.  If you don't have a chrome model, then don't uncheck it.  

    Again, I'm not 100% sure if I'm correct here.  So if someone else gives you different advice, then ignore mine.
