CURA Compensate wall overlap

Recommended Posts

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.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
