ER15 ultimaker 3 Extender


Recommended Posts

Posted · ER15 ultimaker 3 Extender

I have a printer ultimaker 3 Extender which has had problems especially in long impressions when it stops saying in the indicator ER15 which is something related to the temperature sensors of the print core as I understand, we try to change the print core as the page "https://ultimaker.com/en/resources/23149-heater-error-on-printcore" said but the error happened again, by checking the monitoring of the print I noticed that in a flash shot to 700 someone could help me with this thanks

    It's probably a loose cable in the print head.  This is extremely easy to fix.  Remove the rear two screws - very long screws at the top rear of the print head.  After you pull those out the panel on top of the print head towards the rear half comes off.  Then push the cable connector down better and when you put the cover back on push the cable in a little for strain relief and also add some blue tape or other shim so the cable doesn't slide up again.

    Hey there,

    we´ve experienced a simillar error and it occurs still and somehow randomly.

    While Printing our UM3 freezes with the ER15 error in the display. After a look at the monitoring of the print it looks simillar to your posted curve. After Contacting our local support we´ve got a solution from the Database which basically recommended changing the Printcores. But it had no effect on the occuring error. We´ve began to change the signal chain part after part ending up with changed printcores, changed Printhead PCB, changed wiring harnes from Printhed to Motherboard as well as numerous updates to the latest UM3 Firmwares. But still the error occurs randomly. The last possible thing would be to change the Motherboard but is it really nessecary? Is ther no direct support from Ultimaker for problems which are not soluable by the solution Database or the knowledgesources on the website etc.?

    Hope you can help me, thank you in advance.

    When I had such issue with Er 15 printhead disassembly fixed it. I disassembled printhead, removed and cleaned printhead PCB board and assembled everything back. First of all I tried to reconnect rear printhead cable but nothing hapened.

      • 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
