Posted · Hot end fan insufficient voltage.

Hi, everyone.

I have Ultimaker 2+. It worked fine for a year, then hot end fan began to rotate slowly. I replaced it. The new one worked for three weeks, and then the same problem occurred, afterwards it stopped. I measured voltage. It was 2.53V both at the end of the cable and on the main board, instead of 5V as it should be. Have anyone faced similar problem? Any advices?

      • Release Notes: S-Line Firmware 8.3.0 (Latest)

        Dustin posted a topic in Firmware,

        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.
