UM2 extrusion always stops

Posted · UM2 extrusion always stops

at first some prints starts well and then in the mid within one layer no extrusion anymore and the feeder is grinding in the material.

so i disassembled the feeder, cleaned it, tried a small print with no problems, but with a longer print extrusion stops.

so i disassembled the hot-end, and saw that the coupler was deformed (with only 250hrs on it, the last one was over 600hrs).

the nozzle was clean, so i put a new coupler in and started printing.

at hour 11 from a 12hrs print it happened again no extrusion anymore.

The feeder is just grinding and little to nothing comes out.

When doing an atomic method and push the material through i get a nice strand, but that does not help.

      • 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.
