I really appreciate you typing all that for me, but unfortunately, it’s like you’re giving lessons for landing a 747 and I only moved here yesterday from the darkest jungles of Africa and I never saw a plane until today. But less ignorant 3d printer enthusiast will hopefully find the information useful. As Rocky said “I’m just a ham and egger”. He knew how to box a little but knew nothing about the finer points so that he would be competition for Apollo. I’ve heard terms like heat creep (ond others), but I don’t know what it means. After I learn a lot more, I’ll return to your piece. Thanks
