ULTIMAKER 2+ FANS


Recommended Posts

Posted · ULTIMAKER 2+ FANS

hi there,

my Ultimaker 2+ is blocking inside the tube due to (i think) heat creep, all other parts are running fine apart from rear fan.

i have checked all the connections, they look fine, looked at the soldering on the motherboard, looks fine. and now i dont know why it wouldnt be running?

    If the rear fan doesn't spin you do get blocks mid-print or at the start of a newer print after things have cooled down.

    The problem is almost always in the wiring just inside or above the print head. Remove the plastic netting (slide it up or cut the heatshrink off the end if necessary and slide it up) until you find the 3 white fan connectors. The two that are connected together with a short loop are for the side fans. The other one is the rear fan. Try jiggling that connector while the nozzle is at 70C (fan comes on around 50C). Consider just cutting those connectors off (with power off) and soldering the wires directly.

      • 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.
