We have an older Okuma with the OSP700 control. Other programmer handles it. He was on vacation a couple weeks ago, and I could only load one program. A one block program stays in the control to retrieve programs via DNC. Once the main program was loaded, it wouldn't even accept another one line program.
Today the programmer/set-up guy couldn't even get one complete program in the control without deleting a couple operations. Been a few years since I had anything to do with this machine, but I do remember having several programs in it at the same time.
Why are we losing memory space?
