You need to set the support interface gaps to 0. A quick trick you can do is make the pla you want to use “support for pla/petg” and then in the support interface material selection, pick that filament. It will ask you if you want it to change all the necessary settings for you. Click yes or ok. Then go back to your filament list and change it back to the pla you want to use. Then go back to the support interface material selection and change that back to the filament you want to use as well.

Also not the pla filament profile up the nozzle temp of the pla to 230 & change the bed temp to match that of the PETG you’re printing. Then go to your speed settings and change the interface speed to something low like 40.

Nice! What is your interface pattern and interface pattern spacing set to? Make sure the spacing is set to 0
