I am engraving some writing on a plaque made of aluminum that is 5 inches by 2.5 inches. I can get down to the bold line in the program down below but then I get a "257 Prog Data Error". I looked it up and it says it is a corrupt program, so I deleted it and reloaded it but the problem persisted. HELLLLLLP!!! I am using a HAAS CNC Mini Mill.
