im having the strangest problem ive ever seen. this is on a KIWA KH-45, FANUC 31i model A. using a touch probe, while at B0 I find the Z postion of the face of a part the USER and RELATIVE screens read Z 1.38 , i rotate B axis to B180. and probe the same face that was measured at B0 and Z reads Z-1.27 but it should read Z-1.38 Z is off by .11. if i rotate to B90 and probe that same face in X it reads X1.32 but it should read X1.38 so its off by half as much as at B180.. this machine is in a 2 machine cell with a 24 pallet fastems system, so i put the part and pallet in the other machine and every thing works and reads exactly as it should. hopefully someone has advise or solution because i am stumped on this issue. i have to assume its a issue with the controller because i have confirmed that the part is parrallel to X and Z axis at B0, B90, B180.
