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

    Here are some things to try:

    • make sure you have properly cleaned the new bed; ipa or dish soap. I have gone so far as lightly sand my new pei sheets with high grit sand paper to improve adhesion. Try the list below before considering sanding.
    • bed temp: as you mentioned a cooler bed temp may improve corner curling. 50c or just yolo it and turn it off
    • sounds like you’re printing with PLA: maybe slightly lower your hot end temp.
    • mouse ears at the corners may help keep them from curling.
    • make sure your printer isn’t catching a cool breeze.

      Thanks I’ll give some of these suggestions a try. I am printing with PLA at the same temps I’ve used in the past with the same material. I wouldn’t think the change to pei would require a changing of print temp but I’ll keep that in mind as well.

        One option to consider, and one that solved corner warp for me, is adding in a draft shield to your slices. I add in a 10mm draft shield and have yet to have any issues. Ymmv, obviously, but it’s another option to try.
