I'm having a problem with the infill and top layer in my 3d prints. I did a test with 95% infill rectilinear, and the infill is inconsistent. Instead of appearing gaps with a certain pattern, it seems that some parts get thinner than others. The steps of the extruder are not 100% configured, as I could not because of these faults. Since this inconsistency also appears with the infill in 100% in some parts of the piece. Here is a picture with the infill at 45 degrees: I also tested the infill lines along the X and Y axes, respectively: Does anyone have any idea what the problem might be?
