NoteI rarely struggle with bed adhesion but out of the entire printer, this is the only one that gave me trouble. It kept getting knocked off. I ended up having to use a brim and enable z-hop to prevent it. Make sure supports are only used on the one end and that you don't generate supports through the square holes in the middle where the belts will go in the future. Support under the "triangle" shape against the build plate is probably unnecessary but it's a very small amount and helps ensure that piece, which slides in to the fanhead, is nice and flat.
