I was running a program on my company's 1996 Bridgeport VMC 1000/22 CNC Mill, and after just a few minutes even though I was running the mill at 25% speed it made a loud jarring sound and this alarm sprang up on the screen. So I reset it, and let the machine rehome, and it happened again while it was homing, and when I got it to finally run again I speed it up to 100% and it did it again, I've attached pictures just so anyone who may have run into this problem maybe could give me a hand.
