Thin walls

Hi Guys,

 

I am using Cura with my i3 mega printer. When I print out cookie cutters for my wife, I tend to get one thin wall. I watched the printer and it is at the point where each new layer starts to print. It is like the nozzle is not extruding enough material for the first few mm of print. Is there a way to force the nozzle to start  at a different location for each layer so that this gets spread around or are there better options?

 

Thanks, Terry

    Well make sure the "retract on layer change" feature is off. That will cause exactly what you describe.

     

    I believe this is called the "z seam" and I believe you can randomize this location - I think it's a feature somewhere in cura.

     

    Although the "z seam" is more often created by moving from shell to infill (not one layer to the next which in most versions of Cura I belive happens interior to the part so it's not visible).

    Thanks for the reply. " retract on layer change " is unticked.The inner wall you are referring to doesn't exist with a cookie cutter since the walls are only 1mm thick as it is. I was hoping someone could tell me how to make it "randomize" the starting points.

     

    Thanks

    Yes there is. The setting is under Shell settings section, named Z seam alignment; set to "random". From you comment I would add that your model having walls which are not a multiples of your nozzle width is unlikely to help you in your quest for perfection.
