Nozzle blocked? Please help

Posted · Nozzle blocked? Please help

Hi, I am not having much success solving a problem I am having when printing with the UM3. The printer stopped extruding early in a print, during the first or second layer, please see attached images. The images of the PETG prints were taken on a piece of paper as they were not visible on the glass.


The issue first started when I was printing with PETG, see Images 1A&1B, after cleaning the print core and manually feeding filament through the nozzle I tried again to print PETG, same issue, see Image 2. After cleaning the nozzle and the feeder I decided to try PLA, once again this issued happened, see Image 3.


On every occasion the feeder ground the filament, see Image 5, and I could not get the UM3 to unload the filament, the nozzle end swelled up due to pressure see 4mage 4.


An image of the print core (left) is attached, see image 6.


These are the setting for both filament. these have worked well in the past.


Printing PETG

Bed Temp - 70°C

Nozzle Temp - 245°C


Printing PLA

Bed Temp - 60°C

Nozzle Temp - 206°


The feeder is set to the middle mark.


Any suggestions would be appreciated.

        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.
