Posted · UM2 head on UMO+ (fan problems)

Hello,

 

I have a Ultimaker Original with a 2.1.4 board. I put a UM2 head on it and the fans don't spin all the way on full power. Checked the main fans and the voltage I getting is 6V, which is half or fourth of what I should. The hotend fan isnt working either when the temp goes above 5V. I flashed the firmware with that from the custom builder (bUltimaker builder) and also tried to compile one of my own. Not sure how to fix it and wondering if there was something that would work. Thanks!

Read on to find out about all of these improvements and more.

        Dustin posted a topic in Firmware,

        (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.
