Does anyone know how to turn on the 4th axis on a Tree 425 with a Dynapath Delta 50 control? I have wired everything up according to factory specs, however I need to be able to turn the control on. I have been told I may need a floppy disk to do this. If so, where can I obtain one. Or can this be accomplished by changing parameters? If so, does anyone know what they are. Thanks!
