Hi,

I am an owner of Ultimaker 2 for about a half a year. Since a week I have been experiencing problems with cooling fans. I try to turn them on at the start of machine.

I go to the maintanace - > advanced - > set fans speed - > set 100% and nothing happens, the voltage on fan pins are 2.5 V.

Where can I look for reason of this issue.

Best regards

Piotr

    that's what i tought as well. if you set fan speed the gcode regularly checks if fan speed set to zero as this is what usually is the setup in the gcode.

    when i had this problem i waited the print to start and then set the fans and leave it in the set fans menue that way it stays the value that is on the display..

    The transistor responsible for fan's pwm is conducting electricity constantly - w/o depending on settings in controller. I think it is dead.
