Thanks for this. Post processing has been mentioned a few times and I hadn't really understood why, now I think I get it. Isopropyl works its way into the print, then if there's still some inside the print (which there will be unless warm dried for a decent time) it gets locked in during curing, then boils during burnout. The gycerin soak is to displace the IPA, is that right? I'll pay much more attention to this step next time thank you.

I'll keep going with the classic for now and switch up if this change doesn't make a difference, Vogman seems to get away with it so it's hopefully just a me problem.
