Keep getting 'One material seems to be empty' while printing TPU

Posted · Keep getting 'One material seems to be empty' while printing TPU

Hi, 

 

I've been printing for a while now using two Ultimaker S5. The only problem I encountered so far is that when I am printing with TPU, the printer repeatedly stops the print and prompts the message 'one or more materials seems to be empty'. I'm printing with regular Cura settings and does not have altered the tension on the feeder gear. What can I do to prevent this error message? Lowering the print speed or feed rate? It is a real bummer to come back after a weekend and only see some layers being printed and this message on display. 

 

Regards, 

 

Michiel

    Flexible materials seem to trigger more often wrong flow-events than other materials. I would expect that Ultimaker is currently working on improving that situation and providing a fix in a future firmware version. Something you can do for the time being is to disable the flow sensors in the settings menu of the S5. This will prevent the printer from a wrong interuption but of course might lead to a lost print if a real flow issue occurs.

        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.
