@EvanFoss I don’t know about how common it is but @SachaGloor had flare and printed well, and now @Annino who also had flare has done a beautiful set of test prints here, even @Steve_Johnstone’s latest prints in a warmer environment are looking good see the later ones in this post. So there are definitely printers with flare that work well. None of this is to say that these problems are or are not rare, just that we have multiple good examples of printers with them and printers without them.
