UM 3 randomly stops printing


Recommended Posts

Posted · UM 3 randomly stops printing

My Ultimaker 3 started to randomly abort print jobs and melts the printcore onto the object which is printed.

After that the Printer just display that the print is failed and ask to clean out the print. (No error messages or similiar)

I already tried different objects to print and different ways of printing so via Network or USB. I also already reseted the printer via a sd-card.

But the problem keeps appearing with no recognizable pattern and with all print jobs


Can anybody help me or has some tips how to solve this problem ?

I also added the logs of the last failures at the attachment.

Thanks already,

    Same thing happens to me on my S5. Wondering why and how to lower the print bed so that I can remove the print safely.

    I had that last time, too.

    Normally, you would want to heat up the print core in this situation. For me, that didn't work.  The option is disabled as long as a print part is on the printer.

    When you say the print part is removed, it makes reference run and rips out the rails.

    So better you try to remove it manually.
