Okuma Millac 415V Mill., One problem fixed only to have a new one. The magazine works fine now will rotate in CW or CCW. Not the tool changer arm is stuck under the spindle. It seems that Z zero was not Z zero even though the Z home light was on. Attempted a tool change and the arm hit the tool holder in the spindle and it was .147 off from setting in the proper position in the arm. Needless to say system stopped and arm is now under the spindle. I did manual lower the arm to remove the holder from the spindle. The manual says to do a M31 and then a M180 to inch the arm to a stand by position . I go to MIDI mode enter M31: M180; insert, cycle start and nothing. I tried just doing M31 cycle start and then M180 cycle start not luck either way. What am I doing wrong or is there another way to get the arm back to home position. I am sure I can reset the Z if I can get the arm back and reset the alarm. EX508 ATC Position error (actuator). The manual does not say how to correct this error also the manual says Message bit A17.1. Is there some where I can look at what that means? Thanks guys for any assistance. I have a small CNC mill at home and can fix anything on it. This
