You snipped too quick. It wasn't stuck, but just took about 90 minutes to render it. And the render looks good. So now I'm about to take a load of 00 buck and put it out of its misery. I put a new nozzle in it, and Andy's yellow stuff hasn't arrived so I have a sheet of BuildTak on the glass, the head gap lowered and reduced the global flow to 80%, it laid a brim so-so with the head gap reduced by .1mm, and I went back up to 80C/245C, but 4 layers up its still slobbering and laying extra plastic that looks like snow. But at least it isn't pushing a biscuit of plastic 3/8 in diameter and an eigth inch thick stuck to the botton of the nozzle. So I'll reslice after knocking back the flow a bit more, and maybe set the gap down another .1 mm. Do you have any better ideas? Thanks Chris.
