I've got an ancient Mori-Seiki Lathe with a Yasnac LX1 controller. So far it's been a decent machine. Just got one issue really gumming up the works. We need to use a bar puller for a few production jobs but neither the manual nor the internet seems to have an Mcode list for this thing. Usually there's a code to open and close the chuck, sometimes one to allow that to happen during automatic operation and a pair of Mcodes to switch between feeding in inches per minute and inches per revolution. I just can't find them anywhere. If somebody could tell me or even better post an example that would be fantastic. The usual codes for opening and closing don't seem to work "M68 and M69".
