Is there an existing issue for this feature request?

I have searched the existing issues

The current M142 implementation in layer change for P2S seems to be just copied from Bambu Studio:
M142 P1 R30 S40 U{max_additional_fan/100.0} V1.0 O45; set PLA/TPU ND0.4 chamber autocooling
The RC version of Orca had also PETG version
M142 P1 R50 S55 U{max_additional_fan/100.0} V0.5 O55; set PETG ND0.4 chamber autocooling
Not sure if max_additional_fan is an existing variable.

Which printers will be beneficial to this feature?

Others

Describe the solution you'd like

While this may (or may not) be a valid solution, the chamber temperature auto-regulation should be evolved with some configurable logic, including heating/cooling switch override.

Describe alternatives you've considered
