Hi everyone,

This is one of my first print test and i tried to change some parameters but it isnt getting better.

What should i change to improve the quality of my prints?
Especially i want to get rid of those gaps

Prusa i3, Ramps 1.4.2, Marlin Firmware, Heatbed, Cura

It almost looks like over extrusion on most of your print, to me at least. Which the gaps would be filament slipping or being chewed by the extruder or the extruder motor missing steps. The side image almost makes it look like you have an underlying mechanical problem with either something loose or not aligned or bent.

Maybe a bit fast?
What speed are you running at? id suggest starting at 40mm/sec and go from there.

@ Floyd

@ PDBeal this pictere is a bit older it is nearly solid on the sides now but its not alined? the sides are quite rough .. perhaps a lower heigh would do the trick?

With the sides not aligned, that's why it sort of looks like a mechanical issue of alignment, loose, or bent.

Might not be a bad idea to look through Print Quality Troubleshooting.

You also have backlash (top left "corner") , that can be the cause of the infill not being stuck to perimeter.
