As tittle say, the button that i point on the screen shot never work for me.
The reason it is not deleting that particular file is that the printer is using it. Uncheck that file and try some others.
nevermind… it only work when the printer is iddle.
Even thought the delete button is greyed out on the right side you can still delete objects while the printer is printing as long as it’s not the file it’s using.
In this picture the printer is busy printing the file “Cuboid…”
I can still click on the other files to show a pop up menu to Delete If I need to.
