CURA Compensate wall overlap

[rmcrabb 0]

Ive been using CURA for a few months and am very happy with the results. Lately I've been printing at higher speeds and more detail. One thing I've noticed is when printing parts with high detail my printer seems to vibrate and jerk very bad. I sliced and ran the same part with Slic3r at the same speeds and the vibration went away.

I noticed by looking and the layer paths that CURA and Slic3r handle walls differently. So in CURA I unchecked the "compensate wall overlap" and ran the file again. It ran just as smooth as Slic3r but with a slight over extrusion where the walls overlap (of course).

It seems to me that CURA is changing the velocity of the print head to compensate the material flow where the walls overlap. To me this velocity change is too much for my machine to handle. I would like to know more about how this "compensate wall overlap" function works and if there are other setting that may help smooth things out and still compensate for wall overlaps.

FYI - I'm running a Makerbot replicator clone with sailfish 7.7 firmware.
