Okuma LB15 tailstock advancing issue..

[Fireater]

Any ideas I cannot got my tailstock to move out on my 1990s Okuma lb15 with the peddles. Don't know if there is a command to input or unlock. Petals, cord switches all check out it just doesn't advance. I reversed the switches and it moves out. I checked the original switch and it to works. Wondering is its possibly in the board? Maybe a fuse? If so can you pull the board to change the fuse without losing all data. I do not have a back up made or know how at this point. Help greatly appreciated.

Have you switched it on in parameter mode? Chucking work/ center work on the same page as your OD/ID chucking. SET to center work.

Use M codes through MDI and takes out issue of Pedals

Question... What are the M codes...

Like I said go to Parameters. I think you only item down 1 page and you will see a diagram showing chucking and center pictures along with the registers for changing from OD to ID chucking and from Chucking work to Center work.
