3D printing in school

A day at school again, working on the rover project with two classes. When school was out, I was talking about the project with some parents when all of a sudden both printers stopped working. After some investigation this turned out to be because we had connected the printers to the power group for the stage sound and lights. This gets switched off after school and that’s when the printing stopped. Unfortunately, this did mean that two items that had already been printing for over two hours, were lost and we had to start the prints all over again. We’ll see the results on Monday...
