Used the Mecreator 2 for 1 week with no issues. Now when I power the machine on the fan speed is very high and only slows down once I heat the bed and start a print. The speed is so high it sounds like a part is going to get damaged eventually. Is there any way to set the fan speed on startup?

Hi,which fan are you pointing at?There are two fans in the extruder.One cannot be controlled,and the other can be controlled by Repetier Host manual control.
