I teach CNC programing and set up for high school students. We have Fanuc Om controller that got a 911 alarm. we have had this before and had to wipe the control clean so I did but know it will not let me enter any of the parameters into the machine. When I type them in I can not input, or insert them in any way. I need help because I'm at a loss on this and we have an open house for the community this weekend. Thanks
