I have even left mine run all night when it was on a long finish cut. I like to stay close when it's running but I can multitask at the same time. It's almost like having another set of hands without the people hassle. I have 4 stations set up. While the machine does it's thing I can make new files for projects, cut and glue material to needed sizes, sand and stain, and poly or spar.
It works good for orders big and small.
The more you use it, the more you will trust it. BUT.........there's a reason we name them after women. You still can't become too complacent.
