As others said, dish soap over IPA. I've also had shite PLA before as others mentioned. Find a good brand and stick with it. Also, magigoo is amazing. Basically glue but not glue. Designed to stick when the bed is hot then release when it cools. I add magigoo any time I have a long print where I worried about potential warping or lifting.
Stop using the fucking service! I'm so sick of people complaining about all of these tech companies, but they continue to use it. People need to realize they have an addiction issue and treat that shit.
100% agree, just listened to it recently and wow was it boring. That and Foundation, thought since liked the show that I'd like the books, wrong. Those are the only 2 books so far that I just couldn't get into. But I suffered through to the end with both. Even started the second Foundation book and then asked myself why I was torturing myself.
