I have a Mycenter 2Xi with a Fanuc 16i control. Occasionally the spindle orientation during tool change will be as much as 5-10 deg off. Meaning that the drive dogs will not be in the correct position for the ATC arm to put the tool into the spindle. This will only happen when the spindle is in High Gear, the spindle must be switched into low gear for it to reliably orientate to the correct position. I have searched the manual and can not find any help on this.
