Hello I've got an error message saying "Toolchanger has no basic position" after pushing "Internal Stop" after a tool change. The books instructions want me to use a function that is greyed out. Nothing will move or respond. Anyone have any ideas how to fix this? It sure seems like they should make machines that just don't do this or if it does, up pops a window to guide you through the fix. Other machines are pretty easy to fix this stuff, but this is not intuitive at all.
