Hi everyone!
I am new to this forum so please let me know if i posted this in the right section.
I have run into a problem with my Duplicator i3 using Simplify3d.
I have read about the retraction settings and tried a few times with different combinations, and I did end up eliminating most of the strings.
The only problem is, that the printer seems to be under-extruding some layers or areas of the print, leaving a weak point.
I have printed a 3dbenchy prior to changing the retraction to have a control.

Another thing is, the printer seems to be leaving gaps between some walls leaving a hole in between the two faces of a print.

Anyone have experienced this issue and managed to fix it?

Thanks!
