Was talking to a young man on youtube the other day about the all in one cooling solution on the adoptabot. He had a good point that for printing PLA you don't want the part cooling to be on, but you need the hotend cooling on. So I'm thinking it might be worth it to separate the two out. I see that Printrbot has hotend cooling brackets on youmagine. I may try that. What are your thoughts? Worried about first layer if part fan is blowing?
