Very Rough Edges on Robo 3D R1 Plus

[philline]

On my prints, as you can see, the sides are coming out extremely rough. The bottom layers are smooth, but when it starts building the sides, it lays out the 2 outside beads smooth, then when it fills in between those beads, it shakes/vibrates and seems to push out the smooth outside beads causing the roughness. The original.stl file looks perfectly smooth. I get the same results with Matter control slicing as I do with Simplify3D. None of the machine parts appear to be loose. Is there any setting in S3D that will correct this.

Looks like either a lot of over-extrusion or a machine issue
