Need help with this gaps in top layer


Recommended Posts

Posted · Need help with this gaps in top layer


I use Cura 4.8.0 on my Windows 10 machine. I have a small part to print. I used the draft settings, changed 'wall line count' from 2 to 3, changed infill from 20% to 40%.
If I slice I get a small gaps in the top layer of the lower part, see image:


If I set wall count back to 2 then the gap disappears:



How to get rid of the gap if 'wall line count' is set to 3?

The *.3mf file is attached.

Thanks for any help...

    This might actually be a bug.  This is the second model with this problem in a week.

    If you change the "Inner Wall Line Width" to .3 the gap goes away.

    It's such a small part, why not change the infill density to 100%?  That makes the gap go away as well.


    This problem seems like it comes up when there is a small dimensional difference between the top feature and the base feature.  Cura typically puts the walls of the top feature on a solid base but in this case (and the other) this doesn't happen unless other settings are fudged.


    EDIT:  Here is the other instance. "Gap in Wall"

    Hi Greg,

    orthographic does not help unfortunately.
    Pan and rotate are smooth, but scrolling using the wheel just provides rough steps.
    Is there any keyboard shortcut to zoom without the mouse wheel?

    Plus and Minus keys either on the numeric keypad or the regular keyboard.  They still want to jump though.  The mouse wheel "jump resolution" might be a result of the way scrolling is set in your Op System Mouse controls.
