so I am looking at some of these patterns, is it normal these printers to be running for hours. I mean I was told there are some where it takes 3 days total? 7 hours, 18 hours...are these machines made for it. I will admit I am nervous about starting one of these longer prints. I just got an Ender 3 neo and don't want to burn it out on one print any advice or guidance would be appreciated. I know these prints take a long time. but just want to make sure the machines are made for it.
