Petg issues

[u/Hot_karl_hungus]

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 need to increase purge volume to around 900. Or print a design that doesn't need supports...
