I've been having some trouble with my fans on my UM2+ lately. I noticed that this post describes similar issues to what I'm experiencing:

So I decided to follow the test instructions. Here were my results:

Test 1: T1 0.841, T2 0.841

Test 2: T1 0.856, T2 0.992

Test 3: T1 0.053, T2 0.671

 

Does this mean that the T1 transistor needs to be replaced?

 

UPDATE: In case anyone else is experiencing a similar issue, I did need to replace the transistors. I consulted a friend who is more experienced with circuit boards than I am, and he confirmed that the transistors were probably in bad shape. I ordered part number BC817-16FDICT-ND from Digi-Key, and my friend swapped out the old transistors for the new ones. The fans started right up with no problem! No need to kick them, and they are properly cooling the prints now. Thank goodness for these forums or I would have been totally lost!

The problem has been solved and I wanted to include an update with the solution.

      • 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.
