Hi advanced members.
I am a newbie, I have my ultimaker now for couple of weeks. One day i noticed the extruder fan is always turned on, usualy i can control the fan from ulticontroller (Temperature > FAN) but now i can't.
I still can print without any problem, but i checked the voltage. it's 19 Volts (for 12 v fan)
Sould i worry about this? is there any trouble with the board?
Thanks.
