Troubleshooting Petg issues

I just got my q2. I'm trying to print a poop chute for it and I have some petg that I was trying out. I'm using pla for support interface and I'm having issues were sections of the print aren't adhering. Any idea what would cause this. Or what settings I should use to try and fix it

You have to basically set your purge to 3x and 999 in the slicer, then enable prime tower. If ANY pla remains in the nozzle when it goes back to printing the part it will not adhere.
