0.01mm deviation in Y for all tips

Hi guys
so i have this simple check program of a guage ring where i measure it with mastertip, align to it and then measure it with all the other tips in my rack.
so the other day i noticed all the tips following mastertip had a deviation of 0.01mm in Y.
so i thought maybe someone had crashed the tip and then i re calibrated all my tips.

I ran the check program again and the results were the same!
the roundness of the ring is a few microns, so no shaft hits
and the calibration results were good too, between 0.001 - 0.002 std

what can i do

  • no the machine wasnt homed, and yes
    we have a autocalibration program that goes thru all tips
    YES to first master tip, and then no the rest of the tips
    but !!!!!!
    later we needed to add a new angle to our program, so i added the new angle, measured the sphere with master tip (yes the sphere as moved), and then calibrated the new angle with (no).
    but that shouldnt affect the chain no?
