RT program moves away

[[SH...]]

I have a part, something like a worm shaft,a thread at centre and two cylinder top and bottom. I create two circles top and bottom and a point at top then created a 3D line using these circle for base alignment. 3D lines space axis is Z+. Used same features for RT alignment at zero and 180 degrees. When I completed the manual base alignment and execute in CNC mode, Probe moves to Z Plus clearance plan and instead of 5 stylus it try to hit 3 stylus and collided with part. Something like RT alignment is flipped.
When I did manual base alignment using the button inside the base alignment definition template, and run the part in CNC mode without manual alignment program running well no problem.
When I select one feature and runs the program using current selection for running only that feature same problem comes again.
I created RT axis by symmetry construction as usual that 3D line from zero and 180 degree RT position.
My wobbling and eccentricity is within 20 micron.
I can't run the program in manual alignment and obviously I can't run by selecting any particle feature.
I know it is something simple, but can't figure it out.

Hello Shabu,

Just a thought here, not necessarily a fix, but maybe something that might help lead to one. Have you tried turning on "Show probing object" in the CAD menu (That's CAD>CAD model control>Show probing object specifically). If you have that on, Calypso will show where it thinks the probe is. It unfortunately doesn't show it while it is navigating, but it is still very useful to see where Calypso thinks the probe is and I find it helps me find the root cause a lot quicker.

Beyond that, it almost sounds like an alignment issue, but it is hard to say without the program in hand.
