Please do not print past 3 pm. If you need to print something that will go beyond the 3 pm finish, email the file and Prusa specifications to Miss Pringle, and it will be printed off-site using Creality slicer. Power to the 3D Printers will turn off at 3 pm.
Always turn on the fan behind the 3D Printer machines - don't open the windows above. The power switch is on the powerboard that the power cord is connected to. If you need help figuring it out, please ask.
