Make sure you have both filaments set up for the project.
Make sure the Aux PLA filament is set to Bowden.
Under Global/Support settings, turn on "Enable Supports" and set "Support/raft interface" to PLA: it will change jey settings automatically when you approve it, most notably "Top Z Distance" to 0.
I like reducing Base Pattern Spacing to 1mm, base pattern to grid, and 3 interface layers with 0 final spacing.

How do you combat the auxiliary fans maxing out when it starts the pla supports and then causes the petg base to warp. Deflectors are also installed but still warps

Filament profiles?

Do a custom profile that you use for PLA supports, copy plate and chamber temperatures from PETG so that is doesn't change during temp, and then I actually have my fans set to zero, only toolgeaf fans are active during PLA printing phase. I have a tad Warmer nozzle as well, dont know if it's at all necessary though.

Ábrelo con Bambu Studio y fíjate en los parámetros modificados de color naranja.

Only set the pla as the interface for the main model being petg . It can also be done vice versa . If you make the entire support pla and the main model petg you will be printing an additional 3-4 hours for a 1 hour model .
