Cooling fan stopped working midprint, not working anymore. UMO+

Posted · Cooling fan stopped working midprint, not working anymore. UMO+


Today during a 3 hour print my cooling fan suddenly stopped working.

The fan output on the board isn't working anymore for both printing or via the ulticontroller command.

At first I thought the fan died but I tried 2 other ones but they all didn't work on the fan output on the pcb but did work on the 'always on' 24v output on the pcb.

The soldering looks fine and board didn't short out or anything like that.

I restored the board multiple times with no results.

All the parts on the printer are stock Ultimaker parts.

Can anyone please help me? I have no idea how to fix this , the board is only two months old and barely used.

    I would call your seller for warranty support.

    But also, (I would ask them first just in case it affects the warranty, who knows...)

    So, you could swap the FAN PWM to the LED PWM. Then I would install this https://bultimaker.bulles.eu firmware. Just choose Ultimaker Original + on the printer selection.

    This firmware with the default settings adds an option on the ulticontroller to control the LED PWM connector.

    And with the ulticontroller you can raise the led (while having the fans connected to it) and see if it works.

    Thinks that can kill the PWM FAN:

    - Connecting the +/- inverted kills the transistor

    - Using too high mA fan to the pwm fan kills the transistor

    So if you didn't did any of that, just call your reseller or ultimaker distributor where you bough the kit.

      • 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
