I'm using Cura on a Reprap Mendel. Im getting vertical ribs or waves on smooth surfaces on my prints, on all sides.
Reprap forum suggest I try a different slicer, but I love Cura because its the only slicer that I found that does infills.
I print a round gear or a box and I get the ribs on the sides, as a matter of fact if I load the gear into Cura and zoom in on it, it shows the ribs.In the past I used Slice3r and had no ribs, but the gear printed with gaps in the teeth. I would give a pic of my problem but my present camera dosent do macro. Please help.
