unwanted lines on surface

Hi, I can see what's happening, it's not retracting when moving between the first set of walls it outputs (the innermost walls). This could be related to a known bug (currently not fixed) or it could be something different. My only suggestion at the moment is to have retract before outer wall enabled and print outer wall first enabled. That combo should ensure a retraction occurs. Also, I notice that you are not using the wall order optimization which is available as an experimental feature. If you enable that it will do less traveling. Hope this helps.

    Retract before outer wall is in custom settings -> travel

    Outer before inner walls is in custom settings -> shell

    To see these preferences you may need to go to Menu settings -> configure setting visibility

    Cheers,

    Mark

    Thanks for the file. Yes, it's still not retracting on some of the travels. I think this could be related to an existing bug. What happens if you turn off combing altogether? I would expect that to force a retraction for all moves.

    I've had a chance to look at this some more. With your recent gcode, it is retracting when crossing the red regions but it isn't doing a z-hop. This is controlled by the combing code which I believe has a problem in this area. If you turn off combing it should not do this.

    That's the same file as you posted yesterday! Combing is set to no skin, I would like to see the gcode that corresponds to your latest better print.

    That looks a lot better. Note that you will get fewer travel moves and retractions if you enable the wall order optimization.

    Anyway, the root of your problem was the bad travels (with no z-hop) caused by combing. There's definitely a problem with the combing still.

    I am having this exact same frustrating issue. The keychain on the left has little blobs of red above the small letters made during the combing maneuver. When I changed combing to 'No Skin'. I ended up with tons of crossing lines even though I had 'Retract Before Outer Wall' and 'Outer Before Inner Walls' checked. I found a possible plugin solution, but I can't figure out how to get the plugin installed. https://github.com/Dim3nsioneer/Cura-Plugins/wiki/Retract-While-Combing-plugin. Can anyone help me?

    Have you tried turning off combing completely? I think that helped the OP above.

      • 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.
