Folks - I am trying to print with PETG on MakerGear M3. The issue I encounter at this point is the following:

- I have dual head printer and use PLA as my support material as this allows me to easily purge the support after piece is printed in PETG.
- The problem is that I had bad layer adhesion at the point where PLA support touches PETG. In other words, it looks like PETG does not stick to PLA and I get bad surfaces at those joint layers.
- I tried turning fan off at that transition layer but it lead to bad stringing. I also print at 150 mm/s which I like and not sure if increasing the speed further would help



Much appreciate any suggestions and alternative solutions to be able to print with PETG when I have to use support for overhangs
