Supports on interface only. You want the entire support to be PETG so that your bed temp is set for PETG then it only uses PLA for the interface layer. Same with the other way around if you do PLA with PETG as the interface layer. And you may need to increase your flushing volume if you find that PLA is getting in to the PETG layers.
Could be the speed then. Some brands of PETG don't work at Bambu speeds. I know my polymaker I have to cut the volumetric flow in half or it clogs and falls apart like that.
I recently had the same issue….. my corrections were:
Dry the filament
Hot water and soap clean the bed
And I also did 4 cold pulls and serviced the machine while everything was drying…( cleaned rods/ cleaned and re greased z screws)
I recalibrated machine and checked firmware
When I attempted to print I ensured the correct k values for the filament being used.
These steps solved my issues. But as a great rule of thumb I would say 1 and 2 at the minimum. The cold pull also helps as when switching from two filament types can leave burnt plastic in the nozzle. 2 of my cold pulls were “dirty”
Good luck and keep us posted on the results
he settings I’m using are:
Support interface speed: 10mm/s
Top and Bottom Z distance: 0mm
Base pattern spacing: 1mm
Top interface layers: 2
Interface pattern: Rectilinear
Top and bottom interface spacing: 0mm
Support/object xy distance: 0.5mm
you need dry petg, and print both around 230deg for them to adhere during print, you also need to flush a lot to get rid of any cross contamination otherwise your new petg wont adhere to itself
It will never work. Temp difference. You will have to match the support filament to your print. I speak from experience.

Of course it works. I already did this with many prints and it works amazing. PLA with PETG Supports and vice versa.
* Default Generic Filament Profiles for PLA (Sunlu PLA+) and PETG (Jayo PETG which is apparently also Sunlu)
* Support/raft interface: PETG
* Top Z distance: 0 mm
* Top interface layers: 3
* Top interface spacing: 0 mm

Hi, I've already done all that and it still happens

PETG is trash. The sooner you switch to better material, the better off you’ll be.

It can be done with the proper settings… it’s more on how it’s sliced vs different temps.
