I made an account, and the videos are still super short. Where did you see him saying he's using 150F??? I was told by someone else that you have to troll super hard to actually get info off instagram. I much rather prefer this forum. Tell that guy to come over here!
I saw a few comments mentioning he is doing it at 150F, but couldn't find any with him saying that publicly. He said he is pre-heating his plates, but has coils that are currently in the machine shop being tuned.
