If you cant increase chamber temp, you can try reducing bed temperature. There is a minimum bed temp you need fot first layer, but you can try dropping it even more (5C) after a layer or two. PEI shouldnt loose adhesion and you will have a bit less shrinking. Not sure would that be enough for your part tho, warping is massive

Do you think this is something I could combat with higher chamber temps? I’ve been putting off swapping my acrylic panels for ACM and installing radiant insulation, but if it will help…
Using my hot end thermometer as a chamber thermocouple (hot end fan on high), 75mm above the bed and in the centerish it looks like I’m hitting around 50 °C after 45 minutes or so. I doubt it’s getting much hotter in there.
My bed is already fairly low at 100 °C, but I could try 95 °C after the first layer as you said. I can also lower my extruder temp some, but ambient is still going to be way cooler than the plastic coming out of the hot end.

Higher chamber temp should help and I think its the best way to deal with this issue. If you are going to try a different build surface like Kapton, consider gluing PEI sheet directly on the alu plate instead (not the spring steel sheet, just a PEI)
