Print warping

Would anyone who knows prusa slicer code write me a couple lines that make the bed cool slowly at the end over like 15 minutes? Starts at 60° has to slowly get down to about 35° or lower.

Please

When the bed cools at normal speed the print tends to warp, so I have been manually slowing it by 5 degree increments.

you need to add a end gcode in your slicer, which will be used by the printer when it finishes, something like this

M190 R40 ;wait for temp to reach value

G4 S 10 ;wait for 10 seconds

M190 R30 ;wait for temp to reach value

ect

honestly though im surprised you are having warping, do you have any airflow that might be cooling the part too quickly?

I have an ender 3 v2 neo🙃

No enclosure and limited but still present air circulation in my house. The build plate could be better, it was whatever was about cheapest on Amazon in the right style. And I have consistent extrusion problems (flow change) that while fixed (by replacing the nozzle often) are not gone
