My 2003 mini mill has a random problem,I can be running the same program and it will stop x,y and z axis the spindle will still be running and on the screen it will say running waiting...I can push any button on the screen and it acts like it is in single block mode for a few times then it will take off again.I had the Haas tech install new software and the problem still exists.Now he wants to install a new board and software.Has anyone else had this problem.I called Haas direct and they have never heard of this.
