Brand new X-MAX owner question

[jamescragle]

Hi everyone, I just got an Qidi X-MAX printer and I've been playing around with it learning. This is my first printing journey so I'm breaking a few eggs but I'm having fun. There is something in the box that I don't have a clue as to it's use and it isn't explained in the owners manual (image attached). This forum looks pretty active and I look forward to participating.
