Probe hitting style and show plane profile with hit points X Y Z variation

Hello All

I was moved to another plant with v2019.1 and got some confusion, I really appreciate any help for those issues:
1. Our old v2015.1 when works on calibration, the probe hits the sphere very quick and moves to the next hit. The current machine hits the sphere and stays for a while before retreat. I did read the manual before, I remembered there should be setting to choice those different hitting modes... but can not find it now.

2. When we measure a plane, if the profile is out of SPEC, and shows red, for example 0.059 , the SPEC is 0.075. I believe this is because PC-dmis calculate profile using Lease square method, but the profile is calculated by MAX MIN points deviation. Can we show those points from the plane on the results ( I can pickup points and form a plane, and show both of them, but can measure the plane and show the points by X, Y Z)

Thank you

probe option set up properly? What machine and controller?

What type probing system? Sounds like the older one is a TTP and the newer one is a scanning probe which will exhibit the type of probing your describing.

In your example of profile, could you post a screen shot of the result ?
If the spec is 0.075 on a profile, it should be ±0.0375, so 0.059 is OOT ?
If it's a flatness, then the tol is +0 + 0.075 so .0.059 is ok.
The profile uses the T value, and the plane must be constructed with minsep.
Then
ASSIGN/TVAL=DOT(PL1.HIT[1..PL1.NUMHITS].XYZ-PL1.XYZ,PL1.IJK)
ASSIGN/MAX_VAL=MAXINDICES(TVAL)
ASSIGN/MAX_POINT=PL1.HIT[1].XYZ
ASSIGN/MIN_POINT=PL1.HIT[NUMHITS].XYZ

2019.2 Global which bought 2020. The calibration issue is when the probe hit the sphere, the probe stays there for about 1s, I can tell the probe head, the needle is a little bent.

Yes. The newer one can do scanning job. How to fix it , I did remember I read something for manual before. Thank you

I think for the profile, PC-dmis uses least square method for the plane profile. On the other hand, it will show red if points MAX or Min absolute number over 0.0375. So 0.059 could be MAX + MIN, it could be red or green.
