Help troubleshooting "Failed Print"


Recommended Posts

Posted · Help troubleshooting "Failed Print"

Hi, I had a print fail about 8h in on a 21h print job with no real indication as to why.

See images.(8) The "Failed" display is not - what I recall - the same as the flow sensor detection stop because of underextrusion/clogged nozzle etc. 

This leaves me confused. The spool is free to rotate, extrusion seemed to be happening even after print stop, but there was a tiny blip where it stopped before the print head moved up indicating some flow / oozing before print failure script took over... The print head shouldn't be the point of failure however since it was free to move / reset position after removal..?

Could this be a simple case of clogging/underextrusion still despite conflicting evidence or is there something im missing?
The software & printer are giving me no hints at all.
Is it a known software/firmware thing? (Ultimaker S5 7.1.3 and cura 5.2.1)

Appreciate any reasonable suggestions/directions... hopefully im just missing something simple.

    Update: had a "fatal error" occur and crash report when attempting to restart the print today in cura 5.2.1. Just started printing from cura 5.0.0 instead. I'm not sure its related to a print stopping 8h/40% in on a replicated print, but when two strange things occur its hard to think its not. Praying its 100% a software issue...

        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.
