this doesn't unless the temps are high enough to iron it down, 200C and a bump its all ripped loose, 225C and a bump is ironed down by the next pass. Pretty delicate balance. I'll change nozzles the next time its cooled down like Andy suggested. I have a bag of spares. Gotta figure out how to do it though, it has a si rubber cover I don't want to muck up. Thanks Chris.
