Welcome to the SeeMeCNC Community

Hi guys i'm new to the 3D printing and am asking for a bit of advice to improve my prints, i have uploaded a few images and would like help on what settings would improve my print, the worst part of the print is the inner columns.

My current settings are.
Rostock Max V2
ABS
Nozzle 0.5
Extrusion Multiplier 1.0
Extrusion Width 0.60
Retraction 8.00
Retraction Lift 0.10
Retraction Speed 100
Layer Height 0.20
Top Solid 3
Bottom Solid 3
Perimeters 2
Infill 0 (for this test)
Support 0 (for this test)
Bed Temp 90
Head Temp 235
Print Speed 40

Lift 1mm, retract 4-6, outline overlap 40-80%, more top layers, coast and wipe need tweaking, .55mm extrusion width,

Have you tried printing it with a .50 Extrusion Width?
Under the Infill tab, you can try "Infill Extrusion Width" at 200%.
Also under the advanced tab, try 50% "Allow gap fill when necessary"

edit: jFettig beat me to the outline overlap.

One more thing, checkout this topic. It helped a great deal with fine tuning over/under extruding.
