By the way, is there any way (a setting) to control the speed of the heat break fan?
I had a bad day with several prints failing because of heat creep, I had ironing enabled, then also without it: in the end it was PETG not liking the closed enclosure and 55C. But it makes the printer and thus the room much quieter, so I’d prefer to keep all closed, if there’s a way to avoid heat creep, that is.
