I Have an 8 month old Haas VF2 SS and it has the 15" screen on the controller, but i've noticed that during machining the whole controller slows down and the numbers refresh once a second. all of the numbers including spindle and axis loads. it doesnt keep the real time numbers up. After a min the controller seems to catch up to itself and run smoothly. this doesnt effect the accuracy or machining but it's not right and Haas hasnt been able to offer very much help. I was wondering if anyone else had this problem and might know what is going on with it.
