infill and nozzle travel

Recommended Posts

hello, i was excited to learn about the infill patterns and shell patterns!  i had some odd looking flat surfaces.  anyway, i switched shell top/bottom pattern and bottom pattern initial layer to lines. in the preview, i'm using 3.1, it looks great.  in the actual print - which failed for another reason - it looked like the attached.  as close as i can figure, the out-of-place lines are similar to the travel lines which are previewed in blue on my screen.


is there a way to eliminate this from printing? or is it something other than travel lines?

update. indeed someone else has had this issue :) i saw that retraction seemed to be the issue.  in cura i was able to disable combing mode, i set it to off. then i made sure retraction was enabled.  i did nothing with z hop when retracted.  the 1st layer looks better with no angled line in it and i'd guess that the infill will not have those lines either.

    • "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.
