I've setup my Bambu X1C with an exhaust fan from the printer to the window. This is for when I print with ABS or ASA. Only issue is the printer doesn't exhaust on these filaments. I have set the fan on a smart switch so before I open the door I will exhaust the chamber. The flag will remind me to vent the chamber.

Unless someone can tell me what gcode I use to put the Chmber Fan on for 3mins after a ASA print that would be great.
