I cannot figure out how to remove my 4th axis from my VF2.. If I unplug the cables before powerup I receive an error that locks my machine because it cannot find my 4th. If I try to turn it off in the parameters it will not allow me to because "servo is on!"... Cannot find any info in my manual and nobody else at work knows anything about the machine... Teaching myself how to run it so any pointers would be helpful. Thanks! Michael
