Posted · Nozzle touching printed layer when moving

Greetings,

 

I'm currently experiencing an issue with my UM3 using 2.85mm PLA where the Nozzle barely touches the section it just printed as it travels to continue printing on the same layer.

 

I've tried the following to no avail at .15mm, 210C, and 40mm/s infill AND wall speed:

  • Reduced flow to 90% (read online that it could be caused by over extrusion)
  • Reduced temperature to 205C
  • Changed layer height to .2mm (last ditch effort)

 

I've attached a picture below and please ignore the bottom-right to top-left movement issue as that is just due to me canceling the print.

 

As you can see, the bottom-left to top-right diagonal is the nozzle leaving its path behind as it traveled to another part of the layer to print.

Anyone have some other ideas that I can try to see if I can solve this issue? Everything else about the print looks perfect... except the lines that appear on the final layer.

      • 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.
