Hello everyone,

 

I started to notice a progressive under extrusion (ABS, PLA, PETG, on both UM3 noozles) when printing large planes.

It happens on every layer: it starts the extrusion properly (on the photo it is possible to see the plane completely covered on the bottom, without gaps) and then, progressively, gaps starts to appear between the lines.

 

Any idea what could cause that? The only reason I could think off would be trying to print too fast, pushing the material faster than the nozzle can handle, but that is not the case. The nozzle temperatures are stable during all printing. Prints were sliced in Cura 5, with standard settings.

      • Release Notes: S-Line Firmware 8.3.0 (Latest)

        Dustin posted a topic in Firmware,

        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.
