This is the most important first print you need to print.
It will allow you to Live adjust Z Hight.
Very short print.

In 5 minutes you will set the printer to print beautiful models.

It is set to test PLA or PETG.
If you use the stl, please use the settings as pictured so it will start printing near you and inside.

Just above is too high
Above that is too low

and top is almost OK

Good Luck
