He’d only mentioned it once. A throwaway comment: “Found a weird Fanuc post that saved my ass.”
Leo stared at the Fanuc screen. The machine was idle. The spindle was still warm.
And Leo wasn’t sure he wanted to find out.
Leo exhaled. He copied the post processor to a USB stick labeled “GOLD” and dropped it in his desk drawer.
