Posted an enthusiastic FR10 review after loading sleeves at a training bench. I've reread it and made myself sound a lot more capable than I was. The demonstrator had the fingers made, tray located and program ready. I loaded parts and adjusted a taught position with help. Still a decent afternoon, but the preparation needs saying.
Add a preparation paragraph near the start, where readers form their first impression. You can still describe what felt straightforward during your own supervised work.
