I just wired up an OKK G4 Graphite mill with the tool changer in the back with a tilt out door. When I turned on the air to the machine it opened the tool change door. I do not have manuals to tell me how to close the door manually. Any help would be appreciated.

I am sure there is a manual way to open and close the tool changer door because there is no external way to access it but I haven't figured it out yet. What I did to get it to close was to turn off the machine, turn it back on and cycle a tool change.

OKK electrical manual has the list of M-codes for the machine in it. Do not be fooled when you first open the book and think everything is in Japanese. They alternate chapters in the book. First Japanese then English. We do not have a G4 electrical manual here but in the DGM400 manual M100 opens the ATC door and M102 closes the door. Most of OKK machines will follow the same set of M-codes.
