Please help, can’t even print one thing on Ender 3 Max neo because I just got it and it is about to print but keeps saying the bed temp is too low and beeping nonstop so I have to turn it off. I wasn’t having this issue at all before, in fact, I was halfway through my 1st print and suddenly the temp went from 60 to 20 and now I can’t get it back up or print anything. What should I do? Should I return it or try again?
