Slicing differences between Cura and Prusa

[ga63rez 0]

Hello,

 

I want to slice a cylinder with 40% rectlinear infill, layer height 0.4 mm, nozzle diameter 0.51 mm, line width 0.51 mm. I have tried it on two different slicers, the first one was Cura, the second Prusa slicer (the files are attached). I have expected to get more or less the same structure with both printer, but in Prusa I get 15 lines infill per layer and in Cura I get 13. What is the reason for that? Did I miss a setting I have to change?

 

If I calculate the infill lines by myself, my result is that I should have 13 infill lines, so this is maybe not the right forum to ask, because it seems to be Prusa working odd, but maybe there is someone out here who can help me.

 

Thanks in advance

Sebastian

40% in The Netherlands = 35% in Austria.

Bankers know this.

 

(16.5 x 40%) / .51 = ~13

 

When I analyze the Gcode, the PrusaSlicer Arachne engine appears to be putting down the infill lines at .45 line width rather than at .51.

 

(16.5 x 40%) / .45 = ~15

Ok, good to know. So I change my location to the Netherlands and then it should work? 😉

 

Ok, how can I avoid that Prusa changes the lines to .45? Is there a setting to do so?

I have tried to change the perimeter generator to classic, but that doesn't seem to change anything.
