Ultimaker 2+ Side Fans Stopped Working


Recommended Posts

Posted · Ultimaker 2+ Side Fans Stopped Working

I have an Ultimaker 2 that I upgraded to a 2+ a few years ago.


Yesterday, both the side fans suddenly stopped spinning. I swapped out the fan cable to see if there was an issue there, but there was no change. The rear fan is working fine and the LED strips appear to be fine as well.


I'm not able to measure the voltage with both fans plugged in. I'm not sure if this is the correct way to measure, but I unplugged one fan, then measured the DC voltage at the fan plug, plugged the fan back in, and did the same thing on the other side. In both cases, I measured a DC voltage of 18.5-19V. I measured the voltage at the LED strip and it was 24.2V.


I have no idea how to proceed from here. What do I try next?

    So I thought maybe the issue was with one or both of the side fans, so I ordered new fans. I plugged in the fans, but they are not spinning at all. I tried setting the fan speed to 100% in the menu without printing, then tried to start a print and then set the fans to 100%. They didn't budge at all.


    What else can I try?

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.

      • Ultimaker Cura 5.6 stable released
        Cura now supports Method series printers!
        A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
