I work as a draftsman for a cabinet shop, was running the cnc for awhile, but my boss wanted me back estimating and doing shop drawings, had to teach a new guy to run it... man he's dumb. Control just went out, had to ship it to Italy, 4 weeks, $4,000 and 2 days of repair later I got it working again. To bad he just didn't $4k, otherwise I might ask for a raise lol.
