Cheers. I've got an FLSUN machine that has a BT7272A board running marlin. I recently switched over to a software controlled fan for the extruder. It works but I have to manually turn it on in the manual settings. I'm pretty sure there is a G code to turn it on and off but I'm too much of a newbie to know what it is or how to search for it. I'm mainly using Slic3r and I see the options for start and end G code. It would be awesome to enable it at a certain temp and disable it at another. Can you guys help me out or point me to a G code resource that can help me figure it out?
Thanks for any help.
