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.
