Are my fans dead?


Recommended Posts

Posted (edited) · Are my fans dead?

Noticed during last print that both side fans are not working. Left one even lost one of the blades, somehow. They're not spinning if I override fan speed in setting during start of the new print. Fan for nozzle cooling working properly.

Could they break because of overheating? I use closed chamber.

If they are dead, can I buy me new fans at any hardware store? If so, what are the specs that I should pay attention to?

    You can check by going to maintence -> advanced -> fan speed and set to 100, if it doesn't spin something's up.

    I would check the connection of the fan wires at the head first, it's under the black wrap near the head, just check to see that everything is connected.

    Secondly, I would check to back to see if there's any pinching of the wires between the print head pieces. If you did maintenance recently, you might have pinched a fan wire.

    Lastly, is the 3rd fan running? when your nozzle is 60+ degrees? The fan in the back blowing forward.

    Found the issue. Fans were not dead, thankfully, the green wire on the bundle of connectors inside the black flexible tube on the top of printhead teared off it's pin. It seems that these two fans connected successively, so it broke both of them. I soldered it back, and fans started to spin again. Main challenge was to actually stuff everything back into this damn tube without tearing something else - those huge connectors just refused to fit in at first.
