Actually, you spoke with an Applications Engineer, not a Service Technician.
I'm teaching a class this week, so my availability is limited.
Per Michael An, Doosan's Employee who probably knows more about Fanuc, than Fanuc does: Please send the back-up data (files) from your machine, and a picture of the tool management screen prior to powering down, as well as a picture after powering up.
You can send them to me, and I will forward them to Michael An. My email is darryl.hardt@doosanmt.com
