Interface layers and support removal.

Posted · Interface layers and support removal.

I’ve been learning cura at a slow rate.  I was doing fine with easily removed support structures.  Apparently, in my exploring, I changed something and now support is very hard to remove.  I think this may have something to due with interface layers but not sure what I need to change and to what value.

 

i need help understanding what might have caused a change in the ability to remove support.

    I don't know the answer.  Just raising the temperature a bit will make the printer extrude a few % more and now support will bond more with the part.

     

    1) There is a setting "support z distance".  That is probably the crucial one.  Make sure it is equal (or larger) to your layer height.  If your layer height is 0.1 then support distance of 0.15 and 0.19 will not do anything different.  But 0.2 will be more than 0.1.  I very very rarely use support so I'm not an expert and not sure what 0.2 z distance means for 0.2 layer height - is it the very next layer?  Or the layer after?  You can ask cura by setting it to each possibility and checking if there is a "blank" layer in preview mode.

     

    2) You can see what settings you have changed in cura from the default profile.  At the top of the settings there is a box next to the word "Profile".  In that box it should say "fine 0.1" or "fast 0.2" or similar.  On the right side there is a star (if you have made changes).  Click that star.  In the box that pops up on the lower right look for settings that are crossed out (it means you overrode that setting with the value in the "current" column).  And look for settings that are italic.  Also click on the tab above that: "Extruder 1" and check those settings.  This shows you what you have overridden in the profile.

      • 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.

      • Ultimaker Cura 5.6 stable released
        Cura now supports Method series printers!
         
        A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
