Perhaps a bit late for the last poster, but in case anyone else needs it -- I recently upgraded my Migbot i3 by installing a Z-probe and while I was at it, I also upgraded to the latest Marlin firmware (1.1.8). The configuration file changed quite a bit from the original version so if you need something to start with, here are my final config files.
Make sure you adjust your travel limits etc.!

Prusa i3 and variants

The solid infill / solid top infill / top infill extrusion widths may be too low. If the rest of this part looks fine, these may need to be tweaked.
I tried three different widths for comparison and it seems that 0.5 mm gives me by far the best infill results, so I think I can consider my original issue to be, more or less, solved.

If that photo is of the bottom layer, then your bed is NOT level. Extruding more plastic is a sudo fix but the correct fix is to properly level your bed.
It is the TOP layer. I noted it both in the first post, and in my first reply.
I also explained that it depends on the starting point of extrusion, it would appear in a different corner if Slic3r decided to start there. Bed leveli

All right, setting all widths to 0.4 mm helped quite a lot; even without calibration and leaving the extruder coefficient at 0.8, the surface is nearly perfect:
(Left is with default (automatic) Slic3r widths, right is all 0.4 mm.)
There are still some signs of asymmetry, but even not considering the problem I'm trying to solve, the surface just looks much nicer. So thanks a lot for the idea -

Are these foto's from a top layer or the first bottom layer?
It is the top layer.
QuoteFrans@FranceIs the under extrusion always at the same position for each object (right top corner)? or does it depends on the direction of the extrusion. Reason for asking is that it almost looks like the bed is lower at one end and therefor there is more distance between bed and hotend on th

Hi everyone,
I've been playing with my first 3D printer (i3 derivate) for more than a month now and while I'm generally quite happy with the print quality, there are still some issues I would like to address before calling the printer "properly calibrated".
The main issue I'm unable to resolve is insufficient extrusion at the beginning of infill (most notably at the top surfaces):
