Small zits and gaps using Cura

[Th3RadMan 0]

For some reason, I keep getting these little zits and holes across my print using Cura on my Prusa MK3S.  I have a feeling it is a simple solution, but it's difficult to pick out the one setting that will fix it.  They primarily form on concave/convex overhangs, but are also visible on vertical walls.  I'm thinking maybe retraction.

 

 

Additionally, there are these little ripples in the center of the picture.  They appear specifically there, on all 3 faces around the print that are identical.

 

 

I'm using Esun PLA, fresh roll, dried, 210C, tried printing from sd card and octoprint, outer wall speed is 30mm/s, acc/jerk is stock Prusa MK3S settings, aligned z seam, no coasting, no outer wipe.  I can print the same model in PS with just a little artifacting in the overhang and no ripples on the side.

Hi Th3RadMan,

 

Try to reduce the "infill overlap" in Cura, this one, is normally set to 10%, however, in some object I'll reduce it to about 3% and this work for me.

 

PS: What you show us here in your print, can be seen using the gcode file viewer in Cura.

The important thing to remember is; use the gcode file that you send to your printer (and not the one shown in Cura after slicing).

 

If the gcode viewer in Cura show "something", your printer "normally" will print exactly that!

 

Thanks

Hello. I am having this same exact problem. Did the solution to @Th3RadMan problem end up being adjusting infill overlap?

Hi @JSched,

 

Never had any feedback on this one, so I do not know, however -using the "gcode file" and view it in Cura will actually give you a "real" picture of how your object will lock like when printed!

 

PS. You need to tell Cura to be able to view the "gcode files" in the "setup settings" -when installing Cura.

If you have not done this, you'll have to reinstall the version of Cura you're using and tell Cura that you want to be able to view "gcode files" as well.

 

This is the important message in here.

 

Happy 3D printing.
