the left print is from 15.04.6 and the right is 2.7
Printing speed was 40mm/s on both verisons
the nozzle is 0.4mm
walls are 1.2mm and top layer 0.8mm in both versions.
temperature was 230 degrees C on both prints.
infill overlap was 15% in both.
This is what is confusing me. Same printer and filament. all the settings that i can compare are set the same.
What??? The left one looks better, right? Maybe zoom in more? It sure looks like it is touching just fine here.
Anyway if it's the same printer and filament then it has to be something in the gcodes. So the main things are temperature, speed, layer height and line width.
Both curas have at least 3 printing speeds, cura 2 has more than 2. You have to check *all* the printing speeds (infill speed, inner wall, outer wall) as any of these can affect the issue.
Same with line width - check *all* the line widths in cura 2. And in cura 15 is your nozzle size an exact multiple of the shell? if not it kind of ignores your nozzle size. So for example if nozzle size is 0.4 and shell is 1mm it will do two 0.5mm wide walls and all the infill will also be at 0.5mm wide.
Like speed, there are many temperatures.
Should be set to 15% in both curas. Check that.
