I need help with the following problem on my "dinosaur" Roku Roku 1979 Vertical Milling machine with a Fanuc 5M control. The machine only moves positive in the Y and Z axis no matter what you do. The problem occurred overnight while it was switched off. I have already reloaded the parameters and this has not helped. I have checked all the limit switches and all are in order, none are stuck. The X axis works perfectly.
