Ulitmaker 2 board dead


Recommended Posts

Posted · Ulitmaker 2 board dead

Well i have the ultimaker 2 3d printer

i updated it to 2+ with the upgrade kit


later on after a lot of successful printing i found that the cooling fans not working well

so i check the wires and ports on the board and there was a dead connection at the printer head

soldered the junction and it worked for a good time


later o i found that the fan 5 volt not wokring so i tried to change it and while iam doing that i accidentally short circuit the wires

and now the board is dead at all ...

doesnt wont to open..only the on light led is on

no connection to the laptop...no TX RX leds working

and no display working

    It would have been best to work on those wires with the power off.  Obviously now.


    So you probably only damaged one or two components.  The schematic is here - about half way down this pdf:

    https://github.com/Ultimaker/Ultimaker2/blob/master/1091_Main_board_v2.1.1_(x1)/Main Board V2.1.1.pdf


    The most likely broken component is U6  which is an A4403GEUTR-T made by allegro microsystems.  I'd make sure pin 1 was at 24V and pin12 was not at 5V and if so I'd probably just replace that.  It's possible something else was damaged but I suspect only that part got destroyed.  So if you are good with surface mount you could try replacing it.


    Or you could get a new PCB either from Ultimaker or you could get a knock off from china.  The knock offs are a bit different - with removable stepper drivers.

    Unless you have multiple UM2's that you want to keep the same for a consisted workflow, I would recommend replacing the board with a Duet3d board.  Basically modernize your machine for less money. It's more silent, and it's network connected, controlled from any device that runs a browser.

      • 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
