Probably too much cooling, for PLA+ I never use full fan.

I would bring the bed temp down some and keep the heat the same or down to 220. Cooling settings?

You will need to dial in your support interface settings and cooling then, also if your bed is too hot or cold it can warp. For PLA+ I usually stick at 55-60c.

I can try this, sick.

What is it doing? Warping? I also would recommend tree supports, and make sure supports only come from the bed plate not starting on the part either.
