This print started fine the first handful of layers before I walked away. I came back later and everyone of these blocks was curling up with the corners lifting off the bed. I just put on the PEI plate, this is the first print on it. I did level the print bed manually with a sheet of paper, the first layers of each block looked nice and uniform. I’m printing with the bed at 60c which is what I’ve always used with the flexible magnetic print mat that came on the printer. Should I be turning down the bed temp with the PEI plate?

Thanks for any advice
